Cuando nos planteamos cómo mejorar la calidad y la eficacia de los sistemas educativos, rara vez pensamos en los patios escolares como espacios de aprendizaje. Y sin embargo, algunos expertos consideran el patio y todos los demás espacios físicos de la escuela un “tercer maestro” por la importancia que tienen en el desarrollo de los estudiantes.

Parte del aprendizaje

Tiene sentido que las familias, a la hora de elegir el lugar donde sus hijos pasarán más de cinco horas cada día, tengan muy en cuenta que el patio sea amplio y verde o las aulas acogedoras y luminosas. Si los espacios educativos fueran estéticamente más dignos e interesantes, la experiencia cotidiana de millones de estudiantes tendría mayor sentido y brindaría más oportunidades para el desarrollo de la sensibilidad y de diversos modos de cognición.

Y es que el patio no es solo un espacio para el descanso entre clases, sino que forma parte activa del contexto de aprendizaje: en él se pueden disfrutar experiencias creativas, artísticas, sociales y emocionales. Por ello, su diseño y uso no deberían ser cuestiones externas o secundarias, sino desarrolladas de manera colaborativa con el alumnado y la comunidad docente. Ambos colectivos necesitan espacios flexibles y abiertos para la socialización.

Más allá de la lógica funcional

Durante mucho tiempo, los patios han respondido exclusivamente a una lógica funcional. Grandes superficies asfaltadas destinadas al deporte o al juego libre han limitado sus posibilidades educativas.

Hoy sabemos que el entorno influye en la forma de relacionarse, en el desarrollo de la creatividad y en el bienestar. El arte ofrece herramientas para activar este potencial, transformando el espacio para abrirlo a nuevos usos.

Y desde luego no hablamos de propuestas relacionadas con la decoración, sino de una apuesta estética y funcional que vaya más allá del esteticismo, de lo bonito. Intervenciones artísticas, instalaciones, juegos de color, propuestas de diseño, elementos escultóricos o murales colaborativos pueden transformar la forma en que se ve, se vive y se comparte el patio.

El papel del profesorado y la comunidad

Cada centro educativo tiene sus propias condiciones. Por eso, la transformación del patio debe partir de su realidad y plantearse como un proceso comunitario en el que están implicados profesorado, alumnado y familias.

El profesorado es el que puede vincular el proyecto con los objetivos educativos y asegurar su continuidad. Alumnos y alumnas son los que saben el uso que se da y que quieren dar a este espacio. Las familias y otros agentes como asociaciones vecinales pueden sumarse mediante talleres o jornadas de trabajo; de esta manera su vínculo con el centro se verá fortalecido.

Cuando el proceso es participativo, no solo cambia el espacio: también se refuerza la convivencia y el sentido de pertenencia.

Análisis, planificación e intervención

La transformación del patio comienza por sensibilizar a las personas involucradas (alumnado, docentes, padres, entorno escolar) para que colaboren en el proceso de análisis de espacio (características e usos) y así diseñar una propuesta de forma colaborativa y contextualizada.

Debemos observar todas las posibles dimensiones:

  • Dimensión espacial: delimitación, organización, tipología de superficies y espacios, elementos naturales y artificiales, señalización, confort y adecuación.

  • Dimensión funcional: el uso de los espacios teniendo en cuenta climatología, autonomía del alumno, usos, polivalencia, diseño funcional de partida y consideraciones posteriores si más adelante se amplía el tipo de usuarios (a horas no lect.

  • Dimensión social y relacional: cómo puede mejorar la convivencia y la comunicación, cuántos alumnos hay, perfiles de usuarios y potenciales usuarios, qué conflictos son más frecuentes, qué mecanismos de socialización y experiencias se pueden potenciar, qué tipo de actividades y valores deben priorizarse.

  • Dimensión temporal: dinámica y organización de los tiempos.

  • Dimensión artística y pedagógica: elementos visuales, simbolismo, identidad.

La fase de intervención constituye la parte más tangible del proyecto; pero tras esta fase es necesario evaluar los resultados y asegurar un seguimiento. La sostenibilidad y el mantenimiento son fundamentales para garantizar la transformación del patio, dar continuidad al proyecto y hacer que el cambio sea real.

Estrategias artísticas

Hablamos de humanizar los patios y contextualizar la educación, a partir del análisis de cómo percibimos y nos relacionamos con estos lugares. De intervenciones que, a través del uso de la estética, el arte y el diseño modifican la relación del alumnado con el espacio escolar. Algunos ejemplos:

  1. Emplear el color con intención estética y comunicativa para delimitar zonas, activar comportamientos (juego, calma, tránsito) o sugerir usos del espacio sin necesidad de incorporar elementos físicos. Tonos desaturados y formas orgánicas para zonas de descanso o circuitos de líneas geométricas en colores saturados para invitar al movimiento o proponer espacios de juego.

  2. Realizar un mural en una pared exterior a partir de un boceto creado en el aula de manera colectiva.

  3. Crear instalaciones sensoriales como recurso didáctico: propuestas espaciales que invitan a explorar con los sentidos a través de materiales, formas o texturas.

  4. Introducir esculturas y mobiliario para actividades de baja intensidad que fomenten la calma, la tranquilidad y la interacción social. Mesas compartidas, pequeños refugios que favorecen el juego simbólico o la conversación, mobiliario en disposición circular, zonas de lectura o mesas de juego contribuyen a diversificar las experiencias del alumnado.

  5. Incorporar elementos naturales que mejoren el entorno. Jardines, huertos o zonas verdes hacen el espacio más habitable y agradable.

Nuevas formas de estar, de juego y de movimiento en los patios escolares.
García Serrano et al. (2017), Guía de diseño de entornos escolares, Madrid Salud, Ayuntamiento de Madrid.

Estas estrategias creativas buscan nuevas formas de estar, de juego y de movimiento, muchas veces construidas con materiales reutilizados.

Repensar el patio es repensar la escuela

Transformar el patio no es únicamente una cuestión estética: no se trata solo de “embellecer”, sino de reflexionar sobre la escuela que queremos y las experiencias que ofrecemos al alumnado.

Los patios, concebidos desde un enfoque artístico, fomentan la creatividad y la convivencia, tanto a lo largo del proceso de transformación como por los resultados obtenidos. La escuela, de esta manera, se constituye como una comunidad que va más allá del aula.

¿Qué supone el ascenso al poder de un milenial en Hungría para élites y votantes jóvenes europeos?

Source: The Conversation – (in Spanish) – By José-Francisco Jiménez-Díaz, Profesor Titular de Ciencia Política y de la Administración, Universidad Pablo de Olavide

Líderes como Péter Magyar en Hungría o Zohran Mamdani en la alcaldía de Nueva York
reabren un debate recurrente en la política: ¿hasta qué punto importan la edad y generación de los dirigentes?

El enfoque social de las generaciones es muy adecuado para contextualizar los procesos de cambio sociopolítico. Generación alude a un grupo social, nacido en un intervalo temporal y socializado bajo la influencia de ciertos acontecimientos históricos en sus “años impresionables” (entre 15 y 25 años de edad).

Ese grupo sostiene relaciones sociales concretas con sus contemporáneos (todas las generaciones vivas) y sus coetáneos (las personas de su misma generación) en un momento histórico.

Pertenecer a una generación no determina el carácter, sino que apunta a ciertos acontecimientos que forjan las formas de relacionarse de un grupo social.

Marcados por la Guerra Fría

La hegemonía política europea y mundial está representada por presidentes y primeros ministros nacidos a mediados del siglo XX, entre 1940 y 1950. Es decir, los años impresionables de dichos dirigentes transcurrieron en plena Guerra Fría. Por ende, líderes mundiales relevantes son septuagenarios u octogenarios. Pero su relevo puede estar cerca.

Ante la hegemonía de líderes políticos más mayores, la llegada de un milenial a la política europea en 2026 rompe la tendencia gerontocrática de la escena mundial.
El ascenso al poder de Péter Magyar (1981) puede interpretarse como una señal de cambio en un contexto de desgaste político y fatiga de las democracias liberales, prolongado, al menos, desde 2010.

En buena medida, el movimiento de los indignados en España respondió a dicho desgaste en 2011, y estuvo liderado por las generaciones más jóvenes.

Hungría se ha tornado en un laboratorio para observar hasta qué punto el relevo generacional puede traducirse en cambio político real. Tras más de una década de dominio de Viktor Orbán, nacido en 1963, la aparición de un perfil más joven no solo introduce una alternativa electoral, sino también una narrativa de renovación.

La victoria de Magyar se vincula a su percepción como líder político menos ideologizado y “capaz de entender y reformar el sistema”. Los procesos de relevo generacional suelen ser graduales y coinciden con momentos de descontento social, en los que la ciudadanía busca figuras que encarnen ruptura más que continuidad.

De la hegemonía de los boomers a la llegada de los milenials.

Varias publicaciones recientes muestran que políticos nacidos en la posguerra civil española, como Felipe González, José María Aznar y Mariano Rajoy, dominaron el campo político hasta la segunda década del siglo XXI.

En España, la generación de dicha posguerra ha dominado la política durante casi cuatro décadas.
En Estados Unidos, Biden y Trump, nacidos en la década de 1940, han dirigido la política en el pasado decenio. En Israel, Benjamín Netanyahu (1949) ejerce como primer ministro, después de dos mandatos previos. Los presidentes de Portugal (Rebelo de Sousa, hasta marzo de 2026) e Italia (Mattarella, en el cargo desde 2015) también nacieron en los años 40. Los presidentes de China, India, Rusia y Turquía lo hicieron en los 50, al inicio de la Guerra Fría. Por último, el canciller alemán Friedrich Merz (1955) y el presidente Frank-Walter Steinmeier (1956) son coetáneos de los líderes anteriores.

Desde una mirada global, la política todavía sigue dominada, tras varias décadas, por la generación del baby boom.

Una nueva forma de conectar con los votantes jóvenes

Aunque ser líder de la generación milenial (que abarca a las personas nacidas en el periodo 1980-1995) no implica impulsar políticas distintas a las aplicadas por los líderes más mayores, sí parece representar ciertas posibilidades de cambio en sistemas políticos percibidos como anquilosados y desgastados.

El factor generacional marca diferencias claras en la relación con el electorado más joven.
Estudios del Eurobarómetro, del Pew Research Center y del Centro de Investigaciones Sociológicas apuntan a que las generaciones más jóvenes participan menos en la política convencional (menor afiliación a partidos, mayor abstención electoral) y están más descontentos con la democracia, pero no son apáticas. Es decir, la juventud se relaciona políticamente de otras maneras.

En ese escenario, los líderes más jóvenes parten con ventaja. Comparten códigos culturales, manejan con naturalidad las redes sociales y adoptan un lenguaje y estilo comunicativo más directo con el electorado joven. Esto facilita una conexión que desborda los canales institucionales clásicos.

Sin embargo, esta afinidad generacional tiene límites. Los votantes jóvenes son también los más volátiles y más críticos: cambian de preferencia con mayor rapidez y exigen coherencia entre discurso y resultados.

Como señalan diversos investigadores, se trata de una ciudadanía menos leal, pero más exigente y crítica. La afinidad generacional abre la puerta, pero no garantiza la fidelidad política. A medio plazo, la ciudadanía más joven tiende a cambiar sus preferencias en función de nuevas expectativas que ofrezcan otras opciones políticas.

¿Puede extenderse este relevo generacional en Europa?

En España, hay diversos ejemplos de liderazgos de la generación milenial: Pere Aragonès (1982), Gabriel Rufián (1982), Marga Prohens (1983), Fernando López Miras (1983), Irene Montero (1988), Ione Belarra (1987), Alvise Pérez (1990), etc.

Europa no es ajena a liderazgos jóvenes. Casos como el francés Emmanuel Macron (1977), el británico Rishi Sunak (1980), la finlandesa Sanna Marin (1985) o el ucraniano Volodímir Zelenski (1978) muestran que la edad puede convertirse en un activo político. Pero el posible “efecto contagio” del caso húngaro dependerá de varios factores.

Por un lado, existe un incentivo claro: muchos partidos europeos tienen dificultades para movilizar a los jóvenes y podrían apostar por perfiles generacionalmente más cercanos. Por otro, persisten los límites estructurales. Los partidos son organizaciones jerárquicas, burocratizadas y con líderes de recorrido dilatado, donde el acceso al liderazgo presidencial requiere trayectorias largas.

Esto significa que el relevo generacional no es automático ni uniforme. Más bien, aparece de forma gradual y desigual, especialmente en contextos de profunda crisis política.

Lo inevitable

Quienes ostentan el poder político tienden a perpetuarse en el mismo. Pero la vida está limitada temporalmente y el relevo político generacional termina por suceder.

Dicho relevo suele acontecer enmarcado en crisis políticas. En la próxima década, los milenials, hijos de los boomers, ascenderán al liderazgo y ello implicará cambios sociopolíticos notables.

La edad y generación de los liderazgos políticos importan, pero no por lo que son dichos liderazgos sino por lo que simbolizan y por las relaciones trabadas con el electorado. La llegada de la generación milenial no implica por sí misma una mutación de la política. Su importancia es simbólica y relacional: representa una demanda social de renovación, nuevas formas de comunicación y otras interacciones entre ciudadanía y
poder
.

En síntesis, la victoria electoral de Magyar en Hungría se enmarca en una tendencia más amplia. En un contexto de incertidumbre y de desgaste institucional, la llegada de líderes más jóvenes no implica tanto una nueva política como narrativas y promesas de cambio.

Latest attack threatening President Trump reflects rising political violence in US

Source: The Conversation – USA – By James Piazza, Liberal Arts Professor of Political Science, Penn State

For the third time in three years, Donald Trump has come under threat by an attacker. Many facts remain unclear after a gunman stormed the Washington Hilton on April 25, 2026, during the White House Correspondents’ Association dinner.

As the investigation into the shooting continues, Alfonso Serrano, The Conversation’s politics and society editor, spoke with James Piazza, a political violence scholar at Penn State, about what is driving the rise of political violence in the U.S. and what can be done about it.

This is not the first time Trump has faced political violence. What stands out after the latest attack?

I think the events of April 25 underscore how dangerous this political moment is in the United States. For the past several years – certainly since Jan. 6, 2021 – the U.S. has been experiencing a period of increased political violence, which is generally defined as violence that is motivated by politics or is intended to communicate a political message or achieve a political objective.

Researchers at the Polarization & Extremism Research & Innovation Lab have documented that political violence has increased in the U.S. in recent years. Several recent examples come to mind: the Jan. 6, 2021, insurrection at the U.S. Capitol building; multiple assassination attempts on President Trump; the deadly attacks on Minnesota lawmakers Melissa Hortman and John Hoffman that left Hortman and her husband dead; the attempted murder of Paul Pelosi; the assassination of Charlie Kirk. In my home state of Pennsylvania, Gov. Josh Shapiro was targeted in an attack on the governor’s mansion.

What’s driving that apparent plague of political violence afflicting the country?

There are several important drivers of political violence at work in the U.S. today, according to my own research and research by other scholars. The United States is currently very politically polarized, meaning that Americans are sharply divided against one another along partisan lines. They are suspicious and hostile toward one another, and this produces a tense and volatile environment for politics and public life. This has produced a “zero-sum” environment in which every election and political contest is a “do or die” moment.

What stands out to me is the moral dimension of polarization in the U.S. Each side views members of the other party not as merely having a different view on politics but rather as evil or immoral. The polarized environment has made political violence more normalized. It has also dampened public backlash against political violence when it occurs. This makes political violence more likely.

Political rhetoric has become much more divisive and violent in nature. This works hand in hand with polarization and helps to further normalize political violence. In particular, when politicians use demonizing or dehumanizing rhetoric to attack their opponents – for example, using words that depict their opponents as subhumanthis fosters extremism and helps motivate extremists to hurt their opponents physically.

Disinformation is also an important driver of political violence. A number of people who have engaged in recent acts of political violence seem to have been motivated by conspiracy theories and other forms of disinformation, often gleaned from social media. Disinformation plays a particularly important role in the context of social media communities, where people are exposed to large amounts of disinformation and are hermetically sealed off from other sources that might challenge their worldview. This facilitates radicalization and has been shown to fuel political violence in some cases.

Finally, I think an important factor is also the current assault on democratic norms and democratic institutions in the United States. U.S. democracy is experiencing pressures that are unprecedented in the modern era. This has had a very damaging effect on Americans’ trust in government, confidence in democratic institutions and value for democratic rule itself.

My work shows that individuals who are skeptical about democracy are much more likely to express support or tolerance for political violence.

How does this moment of political violence stand out from other violent periods in U.S. history – are we in uncharted waters?

While the U.S. is currently experiencing an uptick in political violence, unfortunately it is not unprecedented. One example would be the highly polarized period in the 1850s in the run-up to the Civil War. In this era, there was a sharp division between abolitionists and advocates of slavery. This culminated in political assassinations, an assault on an abolitionist member of Congress by a pro-slavery member of Congress, and a bloody civil conflict in Kansas between pro- and anti-slavery armed groups.

The early 1900s, right after World War I, saw another increase in political violence due to labor issues and violence by the second generation of the Ku Klux Klan.

Finally, the 1960s also saw a period of intense political violence surrounding opposition to the Vietnam War and backlash to the Civil Rights Movement.

Though there are some unique features about political violence today – namely the influence of social media – I think we can look for some parallels in these early periods of political violence.

Any last thoughts?

I believe it is absolutely critical that both Democratic and Republican politicians – politicians from all sides – unite to condemn this attack and all political violence. Political commentators and influencers can also condemn this and all use of political violence.

Research amply shows that what political elites – politicians, political leaders, media commentators, online influencers – say in the wake of these sorts of events has a huge effect on citizens’ attitudes. Political elites can adopt rhetoric that does not normalize this sort of behavior.

If the message comes from across the political spectrum, it will be that much more effective at reducing the public attitudes that nurture political violence.

Enfermedades del pasado: trilobites heridos, dinosaurios cojos y otros males prehistóricos

En ocasiones, los paleontólogos descubren tejidos o estructuras extrañas en los restos fósiles que les hacen sospechar que estuvieron enfermos. La paleopatología es la disciplina científica que analiza estas alteraciones y nos permite conocer qué dolencias padecieron los organismos que habitaron la Tierra en épocas pasadas.

Se han identificado procesos patológicos en una gran diversidad de organismos extintos, desde protozoos hasta vertebrados. No obstante, son más frecuentes en aquellos grupos que poseen partes duras (más fáciles de fosilizar), como huesos o conchas.

Además de aportar datos sobre la biología y ecología de esos organismos, su estudio también es relevante para entender el origen, la distribución y la evolución de las enfermedades a lo largo del tiempo.

¿Cómo funciona la paleopatología?

La comparativa entre presente y pasado es clave para entender los males que afectaron a los seres prehistóricos. Para lograr un diagnóstico, la paleopatología se apoya en una premisa fundamental: las enfermedades se desarrollan de forma comparable en especies actuales y extintas.

Los avances tecnológicos han permitido un importante salto cualitativo en esta disciplina. Al igual que en medicina, los fósiles con anomalías se escanean a alta resolución, usando lo que conocemos como TAC. Con los resultados, es posible observar estructuras y tejidos internos y profundizar en el diagnóstico de la dolencia sin dañar el resto fósil.

¿Qué podemos saber de los dinosaurios por sus huellas?


A la caza del trilobites!

Los trilobites, con más de 22 000 especies descritas, son el emblema del Paleozoico (539-251 millones de años). Estos artrópodos extintos, provistos de un caparazón duro, habitaron ambientes marinos de prácticamente todo el mundo. Además, fueron algunos de los primeros organismos en experimentar la depredación en sus propias carnes.

En algunos restos de trilobites se han podido observar partes truncadas o melladas. Científicamente estas lesiones se ha interpretado como posibles mordeduras de depredadores. En algunos casos, los bordes de estos bocados muestran signos de remodelación, sugiriendo que fueron ataques de depredación infructuosos. Por esa vez, el trilobites se salvó.

Pero ¿quién se comía a estos animales? Se cree que lo más probable es que sus depredadores fueran otros invertebrados durófagos, como cefalópodos, asteroideos, artrópodos, etc. Algunos tenían conos orales y otros estaban provistos de espinas en las patas, similares a las de los actuales cangrejos de herradura. También los había que presentaban apéndices frontales que funcionarían como martillos. Fuera la herramienta que fuera, les permitía romper su caparazón biomineralizado.

Históricamente, se había pensado que los principales depredadores eran los anomalocáridos. No obstante, hoy en día existen dudas al respecto. Se sugiere que sólo los depredaban justo después del proceso de muda, cuando el caparazón del trilobites no estaba endurecido.

Además de lesiones relacionadas con la depredación, en los trilobites también se han identificado anomalías asociadas a otros procesos. Por ejemplo, alteraciones del desarrollo, complicaciones durante la muda o enfermedades causadas por parásitos.

Renqueando en el Jurásico

En los restos óseos y dentales de dinosaurios mesozoicos se han identificado un sinfín de alteraciones patológicas. Algunas se interpretan como traumatismos (fracturas, amputaciones, etc), otras como infecciones, y también se han documentado enfermedades degenerativas o alteraciones del desarrollo.

Pero los dinosaurios no sólo nos han dejado restos esqueléticos, sino también evidencias de su actividad. Estas huellas o rastros (conocidas como icnitas) pueden aportar información sobre su locomoción como, por ejemplo, la velocidad a la que se desplazaban, o de comportamiento, si se movían en manada o en solitario.

Además, algunas icnitas sugieren que ciertos dinosaurios presentaban problemas en la marcha. En estos rastros se observa una asimetría en la longitud de los pasos. Es decir, alternaban zancadas largas con otras más cortas. Una hipótesis sugiere que este patrón podría indicar una marcha irregular, posiblemente para evitar cargar una de las extremidades. El origen, entre otras causas, podría ser una herida o una artritis. Aunque no son tan habituales como las patologías en hueso y dientes, se han identificado marchas irregulares en distintos tipos de dinosaurios.

Por otra parte, en el estudio de las huellas también pueden observarse malformaciones en los dedos y en las palmas. Se han identificado icnitas de dinosaurios con dedos ausentes, fracturados o deformados, así como extremidades curvadas o irregulares. También algunos con excrecencias anómalas, e incluso huellas completamente torcidas. Estas formas aberrantes probablemente reflejan lesiones del animal (fracturas, infecciones, etc.) o alteraciones durante su desarrollo.

¿Cómo se puede saber la apariencia de los dinosaurios si solo tenemos sus huesos?


Evidencias que el tiempo borró

No todas las enfermedades que afectaron a los organismos del pasado pueden detectarse en el registro fósil. La escasa preservación de tejidos blandos genera un importante sesgo, ya que la mayoría de lesiones y dolencias no dejan huella en las estructuras duras ni en los restos de su actividad. Además, las respuestas del tejido óseo suelen ser lentas y, en algunos casos, pueden tardar años o incluso décadas en desarrollarse. Por ello, muchas enfermedades, especialmente las de carácter letal, no dejan rastro alguno en los fósiles y permanecen fuera de nuestro conocimiento en el tiempo profundo.

Otro problema es el mimetismo tafonómico. Durante el enterramiento y otros procesos tafonómicos pueden generarse alteraciones similares a las lesiones patológicas, como abrasiones o fracturas. Por ello, el equipo investigador a cargo del estudio debe ser cauteloso y prestar especial atención a los detalles para evitar identificar enfermedades donde no las hay.

La paleopatología nos enseña que la enfermedad ha existido desde que la propia vida se inició. Aunque rara vez deja huella en el registro fósil, cuando lo hace nos permite asomarnos a las historias de los organismos de una manera completamente inusual: no solo cómo vivían, sino también cómo enfermaban, resistían o no lograban sobrevivir. Incluso en el pasado más remoto, la vida nunca estuvo libre de sus propias fragilidades.

Le paradoxe des jeux vidéo : entre glorification de la violence et émergence d’une conscience morale

Source: The Conversation – France (in French) – By Emmanuel Petit, Professeur de sciences économiques, Université de Bordeaux

Depuis les premiers jeux violents des années 1970, le débat sur l’impact des jeux vidéo divise : corrompent-ils ou éduquent-ils ? Notre recherche montre que la clé réside moins dans la violence elle-même que dans la manière dont les jeux, par leur design et leur narration, suscitent des émotions chez les joueurs – entre indifférence et prise de conscience morale.


Le 5 février 2026, lors d’une interview, le président de la République, Emmanuel Macron, a exprimé le fait que

« [l]a violence qui s’installe dans la société chez les plus jeunes […] est aussi liée au fait que les enfants, les adolescents, sont beaucoup plus exposés à la violence dans des vidéos ».

Les jeux vidéo, a-t-il poursuivi, « où on descend tout le monde, dont Fortnite, c’est pas ça la vie, parce que ça déréalise le rapport à la violence ».

Pourtant, l’engouement récent autour de Clair Obscur : Expedition 33 – jeu acclamé par la critique et primé aux Game Awards 2025 et aux Pégases 2025 pour son approche narrative et son exploration des dilemmes moraux – rappelle que le jeu vidéo peut aussi être un vecteur de réflexion profonde. Clair Obscur illustre la capacité d’un jeu à susciter des émotions complexes, interrogeant le joueur bien au-delà du simple divertissement.

Suscitant l’indignation des gamers, la remarque présidentielle a relancé le débat sur les effets de la violence inhérente à de nombreux jeux sur les comportements des jeunes dans le monde réel. Certes, le chef de l’État a reconnu qu’il ne fallait pas mettre « tout dans le même sac » et que certains usages des jeux vidéo étaient « bons », comme l’atteste en effet toute une littérature en game studies autour des jeux historiques, persuasifs, pédagogiques ou encore ce qu’on appelle les jeux sérieux.

Cependant, comme l’a montré l’économiste Agne Suziedelyte, il est difficile de trouver des preuves empiriques que les actes de violence déclarés par les enfants envers autrui augmentent après la sortie d’un nouveau jeu vidéo violent. Ainsi, les politiques qui restreignent la vente de jeux vidéo aux mineurs auraient, selon l’autrice, peu de chances de réduire la violence.

La question de la violence et de ses effets reste cependant en suspens lorsque l’on regarde de plus près la façon dont sont conçus les jeux de guerre. Notre hypothèse est que certains jeux peuvent générer de le violence, ou rendre indifférents à la violence, parce qu’ils mobilisent la figure du héros et qu’ils donnent la priorité à la dynamique ludique du jeu.

D’autres jeux, au contraire, sont capables de créer un design et un narratif qui incitent les joueurs à une véritable réflexion morale. Dans les deux cas, comme nous le suggérons dans notre ouvrage, Émotions et Jeux vidéo. Une approche comportementale et institutionnelle (Garnier Flammarion, 2026), ce sont les émotions ressenties et exprimées par les joueurs qui sont au cœur de la dynamique vidéoludique et de l’apprentissage moral.

Quand le divertissement efface l’éthique

Un jeu vidéo, c’est avant tout un savant mélange entre la définition de règles plus ou moins rigides (ce que l’on appelle le game) et une mécanique de jeu qui donne au joueur le plaisir (le fun) qu’il est venu y chercher (ce qu’on appelle le play). Dans tous les jeux, les concepteurs cherchent à maintenir un équilibre attractif entre les contraintes (induites par les règles) et la liberté d’action du joueur.

De la même façon, les concepteurs sont soucieux de trouver un équilibre entre l’expérience hédonique du joueur et ce qu’il apprend ou saisit au cours de cette expérience. L’« économie rétentionnelle » du jeu vidéo implique en particulier la mise en œuvre d’une interface vidéoludique (design, narration, cinématiques, etc.) qui suscite en permanence l’attention des joueurs, par l’intermédiaire notamment des mécanismes d’« amplification affective ». C’est ainsi, selon James Ash, chercheur en games studies, que lorsque « les variables [à saisir dans le jeu] sont trop nombreuses, le joueur est débordé et perd le sentiment de maîtrise ; à l’inverse, s’il n’y en a pas assez, il peut s’ennuyer faute de défis. »

En étudiant les jeux de guerre, qu’on appelle aussi des jeux de tir à la première personne – comme, par exemple, Call of Duty, Counter-Strike, Battlefield, Overwatch, Halo, Rainbow Six – les chercheurs en études vidéoludiques ont montré que ces jeux violents déforment la réalité de la guerre en recourant à des mécanismes de désengagement moral : justification et incitation systématique de la violence, mise en avant de la figure du héros, occultation des conséquences de la guerre, déshumanisation des ennemis, invisibilisation des victimes et des populations vulnérables (comme les femmes et les enfants).

Ces procédés – narratifs et ludiques – transforment la guerre en un divertissement sans ambiguïté morale. En évitant toute confrontation avec la complexité éthique des conflits réels (traumas, deuils, dilemmes), ces jeux banalisent la violence et réduisent l’empathie, tout en renforçant une vision simpliste du bien contre le mal. Le joueur ne tire aucune intuition morale de son expérience dans le jeu et passe à côté de la représentation de ce que serait une « guerre juste » dans laquelle les protagonistes respecteraient les normes humanitaires fixées par la Convention de Genève.

Jeux vidéo et responsabilité morale : l’exemple du phosphore blanc dans Spec Ops: The Line

Dans les jeux, la morale a tout d’abord été introduite en opposition à l’intérêt personnel du joueur. Par exemple, Papers, Please met les joueurs dans l’embarras en les confrontant à leur désir de poursuivre la progression dans le jeu qui s’oppose à la possibilité de venir en aide à l’un des personnages virtuels du jeu. Le dilemme moral est dit « impur », puisque le joueur a intérêt à ne pas secourir le personnage. Plus intéressante est la situation où l’intérêt ne rentre pas en ligne de compte comme c’est le cas dans l’effrayant Until Dawn où le joueur doit décider quel personnage virtuel il doit sacrifier, sans que cela ait une incidence sur sa progression dans le jeu.

Dans ces cas, le joueur fait face à un véritable dilemme moral. Apprend-il cependant quelque chose de son choix ?

Dans une version plus récente de Call of Duty: Modern Warfare, le joueur ne contrôle pas un soldat surentraîné (un héros) mais une enfant blessée, traumatisée, piégée dans un espace ravagé. En jouant notamment sur la mécanique du jeu (vitesse de déplacement réduite, absence d’armement, etc.) et sur l’impuissance de son personnage-joueur, cet épisode propose une expérience immersive qui favorise une prise de conscience empathique vis-à-vis des civils, réels ou fictionnels, dans les zones de conflits. Ces mises en situation peuvent ainsi faire naître chez le joueur une réflexion morale plus élaborée.

On peut cependant aller plus loin en évoquant le rôle central des jeux – comme Spec Ops: The Line ou This War of Mine – que l’on qualifie d’« anti-guerres », car ils cherchent à déconstruire la figure du héros et l’esthétisation de la guerre en mettant en scène la souffrance humaine, en provoquant un inconfort volontaire chez le joueur et en refusant de récompenser la violence dans le jeu.

This War of Mine a connu un succès commercial incontestable (plus de 4,5 millions d’exemplaires vendus dans le monde) tandis que Spec Ops: The Line est devenu un jeu culte pour son approche narrative audacieuse et sa critique de la guerre. Une scène en particulier a attiré l’attention des chercheurs : celle du « phosphore blanc ». Conçu pour produire de la fumée ou créer un camouflage, le phosphore blanc est avant tout reconnu et dénoncé par la Convention de Genève pour son utilisation en tant qu’arme chimique. Le 3 mars 2026, une ONG a notamment accusé l’État d’Israël, d’avoir eu recours « illégalement » à du phosphore blanc à proximité de zones habitées au sud du Liban.

Dans Spec Ops: The Line, la mécanique du jeu oblige le personnage-joueur à commettre une atrocité (lorsqu’il utilise le phosphore pour vaincre des ennemis et qu’il tue, par ricochet, des civils innocents) puis l’accuse par l’intermédiaire d’un personnage non joueur (ou PNJ) lorsque ce dernier le met face aux conséquences de son action et de sa responsabilité :

« [T]u aurais pu arrêter. »

Le joueur est incité à désapprouver sa conduite immorale à travers la culpabilité qu’il ressent. En verrouillant les actions possibles du joueur, le récit et le gameplay soulignent ensemble une vérité brutale : en situation de guerre, les « choix » ne sont qu’une fausse liberté, masquant l’absence réelle d’issues morales.

Violence et jeux vidéo : le design comme levier de la sensibilité morale

Résumons. D’un côté, on trouve des joueurs incités à mimer la violence ou a minima rendus indifférents à la violence dans des jeux de guerre standards. De l’autre, des participants qui font une expérience sensible de la guerre et qui peuvent en retirer une portée morale. L’hypothèse que nous développons de façon extensive dans notre ouvrage est que l’expression de la sensibilité du joueur dépend de façon cruciale du contexte dans lequel il est plongé. Les effets de la violence dans le jeu dépendent en conséquence principalement du design imaginé et produit pas les concepteurs et les développeurs.

Le travail effectué par la chercheuse en études vidéoludiques Stéphanie de Smale et ses collègues vient interroger la logique morale et émotionnelle du jeu du point de vue des concepteurs de This War of Mine. Pour ces derniers, « humaniser l’expérience de la guerre » implique que les joueurs ne perçoivent plus les personnages non joueurs comme de simples ressources, mais bien comme des êtres humains. Le design doit aussi intégrer délibérément des moments d’inconfort (et donc des émotions à valence négative comme le dégoût, la tristesse, la peur, la culpabilité ou la colère). La présence d’enfants sur le champ de bataille, par exemple, vise à susciter de la confusion, voire de l’indignation (« Ils ne devraient pas être là ! »).

Le récit, les potentialités offertes par le jeu (mécaniques, interactions) ainsi que le langage et les expressions corporelles des personnages non joueurs doivent conjuguer leurs effets pour éveiller la sensibilité morale des joueurs. En dehors des nombreux témoignages des joueurs et des développeurs, il est difficile d’établir un lien empirique entre inconfort et moralité. On peut cependant mesurer le fait que des situations stressantes dans un jeu comme Nevermind activent sur le plan physiologique des émotions à valence négative. Dès lors, ces émotions peuvent inciter à des actions morales.

Par ailleurs, la création d’un monde adverse, même virtuel, est susceptible d’exposer les concepteurs du jeu eux-mêmes à une forme d’apathie structurelle ou « d’engourdissement émotionnel ». Pour s’en protéger, ceux-ci font appel à des joueurs pour tester le jeu à différentes étapes du processus créatif, évitant ainsi une forme de désensibilisation face à un gameplay émotionnellement éprouvant. Face à une situation répétée de violence, même virtuelle, les individus peuvent chercher à se protéger en adoptant une forme de déni, comme le font par exemple, les modérateurs sur les réseaux sociaux.

On peut ainsi conclure que l’impact réel de la violence dans les jeux vidéo n’est nullement le fruit du hasard. Il dépend, comme le souligne Holger Pötzsch, chercheur en game studies, de la façon dont sont représentées, cachées ou filtrées les formes (réalistes ou non) de la violence, de la manière dont le personnage-joueur incarne (ou non) une idéologie masculiniste héroïcisée, des conséquences tangibles des actions qu’il est amené à poursuive et, enfin, de l’acuité et de la véracité des dilemmes moraux auxquels il est soumis. Ces différents filtres interrogent en ce sens directement la responsabilité des concepteurs au travers de ce qu’ils proposent dans les jeux mis sur le marché.

Hurdles to a hobby: How climate change and ‘runfluencer’ culture impact our daily jog

Source: The Conversation – Canada – By Madeleine Orr, Assistant Professor, Sport Ecology, University of Toronto

If it feels like everyone around you (physically and digitally) has taken up an affair with running in the past few years, you’re not imagining it. Since 2023, running has been the most uploaded activity on the exercise app Strava, according to their annual Year in Sport reports from 2023, 2024 and 2025.

For many of us, running is one of the most accessible forms of physical activity. It is something we can do on our own or with friends. It requires minimal gear and does not rely on a specialized training facility. All we have to do is lace up and go.

However, the seemingly simple practice of running is entangled with complex environmental dynamics. Rising global temperatures and air pollution are making it physically harder and unsafe to run outdoors, and some of the digital tools that many runners rely on carry their own environmental costs.

Strava’s 2023 Trend Report noted that: 75 per cent of athletes said extreme heat affected their exercise plans, while poor air quality affected 27 per cent. We now have to reckon with the reality that, due to warming temperatures, running will become less accessible and safe.

Add to that the rise of “runfluencers,” running fashion trends and a new market of consumer products designed to help runners cope with heat, and it becomes increasingly clear that the relationship between running, climate change and consumption is wickedly ironic.


Hobbies can bring joy, well-being and focus to our busy lives, but so many of us don’t have one. If you’re ready to replace scrolling with stitching, or hustle with horticulture, The Hobby Starter Kit (a new series from Quarter Life) will help you get going.


The dangers of heat

Running in the heat increases the risk of exertional heat illness and heat stroke. Additionally, running in the heat can increase the risk of acute kidney disease due to insufficient cooling and dehydration during exercise-related heat stress.

For those keen to hit new personal bests, running in hotter conditions can impair performance. For example, an analysis of race data uploaded to Strava identified the average finishing time of the New York City Marathon was approximately 12 minutes slower in 2022 — when the temperature was 23C (plus humidity) — compared to 2021, when temperatures were around 13C.

And that’s just a few of the temperature-related risks associated with summer running. In addition to extreme heat exposure, the safety of summer running is also compromised by smoke and poor air quality.

Runfluencer culture

In addition to the climate-driven shifts affecting our daily jogs, the recent running boom and surrounding culture is also shifting how we run.

As runners adapt to rising heat, poor air quality and smoke-filled summers, the pressure to buy, track and optimize intensifies, further entangling running with the very environmental forces that threaten it.

If your social media algorithm is anything like ours, you might have noticed some targeted ads and sponsored content from “runfluencers” highlighting their new favourite running-related products and apps, such as Runna, a British-based coaching app known for its personalized training plans and AI-assisted pacing.

Runna was first launched in 2022, and its online presence jumped significantly after the app was acquired by Strava in April 2025.

Apps like these can help provide structure and prepare for races. However, they have also faced criticism, with experts noting concerns about the intensity of the AI-assisted training plans in regard to training spikes and risk of overuse injuries. Runna has said they “don’t use AI to generate training plans” but to “monitor a runner’s progress throughout their plan.”

While these apps promise efficiency and personalization, they are part of a wider digital infrastructure with their own environmental footprint. GPS tracking, constant data uploads, cloud storage and AI-assisted analysis all rely on energy-intensive data centres.

As running culture becomes more data-driven and automated, even a traditionally low-impact activity becomes entangled with the emissions and the energy demands of digital technology.

Beyond apps, runfluencers are also using their platforms to share their running esthetic — trying out new shoes, participating in the latest running fashion trends and showing off race day outfits.

That, in turn, promotes a culture that normalizes over-consumption under the guise of self-improvement and dramatically increases the environmental cost of what should be a low-impact activity. Such a focus can make running feel less appealing and appear less accessible.

Staying safe on a run

If you are someone with the flexibility to choose when you participate in races, consider pivoting to springtime training rather than slogging through increasingly risky summer training blocks. Not only will your training runs leading up to the race be cooler, but you can also expect more optimal marathon temperatures (2 to 13C) on race day.

For example, in the Canadian province of Ontario, races like the Mississauga Marathon in April and Toronto’s Sporting Life 10K in May offer runners safer racing temperatures and, potentially, improved performance compared to summer training and fall races.

Think about how you engage with running culture and be a smart consumer. Avoid over-consuming products and programs that you don’t need. Remember, running is one of the most accessible forms of exercise we have. You don’t need a bunch of gear and apps to participate.

As climate change intensifies and summer temperatures continue to rise, running will become less safe on hot days. Runfluencer culture and over-consumption in running fashion are dramatically increasing the environmental cost of what should be a low-impact activity.

To counter these trends, opt for spring races, listen to your body, seek advice from human coaches and pick durable gear over following the latest fashions.

These choices matter not because individual runners are to blame, but because they push back against a running culture that increasingly equates health with optimization, constant consumption and digital surveillance, even as climate change makes the sport itself more precarious.

How principles of self-compassion help fight loneliness in the age of AI

Source: The Conversation – Canada – By Li-elle Rapaport, Doctoral Student and Private Practice Therapist, Department of Psychology, University of Manitoba

Amid a rapid, AI-driven technology boom and all the changes it’s entailed, mental health issues due to social isolation have been on the rise. Researchers in social and clinical psychology have documented this shift and coined it the “loneliness epidemic.”

Human connection is imperative to psychological well-being but the world is increasingly disconnected. With technology streamlining our lives, many report growing levels of depression, anxiety and existential dread brought on by the physical and emotional distance it creates between us.

And so psychologists have begun asking: “How do we stay connected to the here and now, and to each other?”

One facet of self-compassion theory — a concept developed by psychologist Kristin Neff that dictates treating ourselves with the same care and understanding as we would our friends — may hold the answer. “Common humanity” promotes the recognition that we are, in fact, not alone since all humans share the same fundamental experiences, emotions and struggles.

The loneliness epidemic

To begin finding a solution to social disconnectedness, it’s important to understand the vehicles that drive it. A 2024 Statistics Canada survey found more than one in 10 Canadians report often or always feeling lonely, a finding that aligns with psychological research on rising social isolation.

At the same time, studies indicate that heavy reliance on digital technologies can both reflect and reinforce this isolation.

Technology, AI and algorithms divide and capture human attention, often limiting exposure to interactions or varied points of view and perspectives. A study by clinical and social psychologists suggests that the motivation to escape everyday life and experience social gratification reinforces the relationship between mental health and AI dependence, especially for people with mental illness.

The more attention spent in the digital world, the less is available to spend with one another.

It’s easy to fall into a pattern of pessimism as we observe technology shifts toward automated entry-level jobs, addictive doomscrolling and students submitting AI-generated homework. These negative emotions, the attention we spend on them and the frustration we feel with ourselves for having these emotions can perpetuate a cycle of self-isolation.

Self-compassion and common humanity are evidence-based tools that can help stop this cycle by shifting attention back to what is important: each other.

Self-compassion and common humanity

According to Kristin Neff, an American education psychology scholar, self-compassion functions on three key tenets: self-kindness versus self-judgment, common humanity versus self-isolation and mindfulness versus over-identification.

Each facet emphasizes intentionality in our actions, both toward ourselves and others.

At its core, mindful self-compassion’s concept of common humanity is the belief that we are connected by familiar human experiences. Personal suffering is part of a shared human condition, for example, and in accepting this truth, we reduce self-judgment and weaken the tendency toward social withdrawal.

Research shows that self-compassion can be exercised like a muscle through interventions that shift awareness of our personal experiences to how these experiences connect us with others.

Appealing to the humanness of our present experiences reduces feelings of isolation and self-judgment and increases life satisfaction. Common humanity addresses our basic human need to belong.

Feeling down about not having plans with others this weekend? You’re not alone in this struggle. It is uniquely human to feel alone and want to self-soothe with a scroll on TikTok. Knowing this, it might be time to take the first step and reach out to that friend and invite them over.

From theory to practice

Demonstrating the principles of self-compassion and common humanity in the presence of others can create a positive feedback cycle. Three action-based practices help exercise control over our attention, centre community, empathize and attend to our “why.”

Invest in community. Allowing technology to seep into all corners of life is not inevitable. Self-compassion teaches that while this is human, we have the power to change our actions as an act of compassion. It is our choice to bring our attention back to the present.

This may mean making an explicit choice to unplug instead of following the urge to respond; leaning into sharing imperfect experiences and mutual not-knowing; talking something through instead of Googling it immediately; practising collaboration over outsourcing thinking.

Practise empathy. Excessive tech or AI use can leave us feeling depleted and disconnected. In order to interrupt the cycle of overusing technology, notice these emotions without judgment rather than feeling guilt and avoiding the guilt through more tech use.

To ground yourself, ask: “What do I need right now?” You may find your response involves uniquely human experiences: food, a cup of tea, calling a parent, fresh air or a walk.

Centre your ‘why.’ Think about why you choose to connect with others. Centre this “why” in your day-to-day life.

If you notice yourself opting for AI to write an email, pause for a moment and notice this reflex. It is human to seek shortcuts to preserve energy. Consider what you might gain from writing that email yourself. Notice any discomfort. Know that it’s human to feel it, and choose to write it yourself anyway. Theory suggests you might feel more connected to your people and to your own humanness in the process.

In this context, self-compassion functions as a psychological counterweight to the isolating tendencies of digital life. It helps reorient attention away from performance and productivity and back toward shared human experiences.

Here’s how Canadian households can recession-proof finances as economic uncertainty climbs

Source: The Conversation – Canada – By Chetan Dave, Professor of Economics, University of Alberta

Canada’s economic policy uncertainty index has climbed back to levels not seen since the COVID-19 pandemic, a sign that a more volatile period may be taking hold. Income inequality hit a record high last year, and youth unemployment reached 14.6 per cent in September 2025, its highest point since 2010, excluding the pandemic.

Most Canadians have had relatively little experience with major economic downturns. Since the early 1990s, Canada has largely been spared the boom-and-bust cycles common in the United States. The country avoided the worst of the 2008 global financial crisis, and until COVID-19, had not experienced a major economic shock in a generation.

In that long stretch of time, Canadians have grown accustomed to relative stability, which makes the current moment feel especially disorienting. We are, as the saying goes, living in “interesting times,” and that is rarely good news for prices, employment prospects, government budgets, business investment or productivity.

Many Canadian households are carrying a fair amount of debt while facing inflation and rapid changes in job markets. What is a typical Canadian household to do? As an economist, I have some practical advice to offer.

Why uncertainty is rising

This ongoing economic angst has several overlapping sources that are both global and domestic in nature.

Geopolitical conflicts, including the ongoing war involving the United States, Israel and Iran, are increasing the costs of everyday items like food and gas. These disruptions ripple through global supply chains, feeding into higher input costs for Canadian businesses and, ultimately, higher prices for consumers.

At the same time, tariff disputes led by the U.S. are causing inflationary pressure and discouraging long-term business investment. This, in turn, weighs on productivity and wage growth.

Food prices are already high in Canada. Will the Iran war make them worse?


Some governments have responded to these shocks with industrial policies, attempting to support or protect specific sectors such as clean energy, manufacturing or technology. However, some economists warn against this approach, arguing that governments cannot reliably “pick winners” better than markets can.

Political fault lines are also contributing to uncertainty at home. Rising anti-immigration sentiment and the separatist rhetoric in Alberta are adding another layer of social turbulence. Without a social consensus, economic planning becomes more difficult and volatility often follows.

Canada’s safety net has limits

Canada does retain an important advantage: its social safety net. Canada spends roughly 18 to 20 per cent of GDP on public social programs — around the the Organisation for Economic Co-operation and Development (OECD) average. That’s below the levels of France, Germany and most Scandinavian countries, but meaningfully above the United States.

Canadians have access to relatively accessible employment insurance by North American standards. The country’s combination of publicly funded health care and income support programs provides important protection during periods of disruption that American households do not have.

But there are limits to that protection. While Canada’s federal net debt-to-GDP ratio stands at 13.3 per cent — the lowest in the G7 according to the International Monetary Fund — the same cannot be said about provincial governments. Large-scale bailouts of households or provinces are not guaranteed because there is no constitutional or statutory requirement for them.

Three things households can do now

Economic theory identifies three ways households can build resilience against a negative income or wealth shock. The first is cutting back spending. This includes spending on both durable goods (such as vehicles or appliances) and non-durable goods (anything with a short lifespan). This can involve delaying large purchases or scaling back discretionary expenses like dining out, travel or subscription services.

The second is shifting spending to lower-cost alternatives, even within the “needs” category. Households rarely have complete flexibility to cut essentials, but they can often substitute within them. This can involve switching to lower-cost brands, using public transit more frequently or seeking more affordable housing options where feasible.

The third — the toughest one of all — is aggressively reducing unsecured debt. Canadian households owe roughly $1.77 for every dollar of disposable income, the highest household debt burden in the G7. Much of that is mortgage debt, which at least builds equity. But revolving debt — credit cards, lines of credit, car loans and the like — carries higher interest rates and greater risk.

Households can do this by paying down the highest-interest balances first, consolidating debts into lower-interest products where possible or redirecting windfalls such as tax refunds toward repayment. Avoiding the accumulation of new high-interest debt is equally important.

Building a buffer

Once those balances are under control, households should build a financial buffer and maintain it even if the economic outlook improves.

A common guideline is saving three to six months of household expenses in case of an emergency. This typically requires setting aside 20 per cent or more of take-home income, depending on household circumstances and obligations.

Canadians have access to several tax-advantaged tools to support this process. The Tax-free Savings Account allows tax-free growth with no restrictions on withdrawals, while the First Home Savings Account offers first-time homebuyers an annual contribution room of $8,000 and a lifetime cap of $40,000. The Registered Education Savings Plan helps families save for post-secondary education.

If you are able to consistently put away funds and invest them based on your risk tolerance, these accounts can significantly improve long-term financial resilience.

Income risk in a changing economy

The harder challenge, of course, is income stability in an age of uncertainty. Canada is primarily a natural resources exporter, and rapid technological change — particularly the rise of artificial intelligence — is reshaping labour markets across other sectors.

Workers face growing uncertainty about which skills will remain valuable and how stable their employment will be.

Because of this, households may need to get creative about diversifying their income sources. This can include investing in additional training or certification programs, developing side income through freelance or contract work, monetizing existing skills through consulting, or building small entrepreneurial ventures.

The current period is unsettling. But households that reduce their debt exposure, build savings and treat the safety net as the partial buffer it actually is will be in a better position to absorb whatever comes next.

Coercion isn’t care, and new laws that enforce treatment and confinement are dangerous

Source: The Conversation – Canada – By Jean-Laurent Domingue, Associate Professor, L’Université d’Ottawa/University of Ottawa

The Supreme Court of Canada has described the right to refuse unwanted medical treatment as “fundamental to a person’s dignity and autonomy, [including] in the context of treatment for mental illness.”

Nonetheless, legislative and policy shift in multiple provinces in the past year threaten this principle — with little meaningful political resistance. It is important to closely examine the conditions and public narratives that have made this renewed use of psychiatric coercion possible.

A legislative and policy shift

In 2025, in an explicit repudiation of harm-reduction principles, Alberta passed legislation enabling the forced treatment of people with addiction disorders on the basis that they are “likely to cause harm.”

Manitoba now allows authorities to detain people for up to 72 hours if, due to intoxication, they are considered a danger or are causing a disturbance.. In British Columbia, the government has opened involuntary care beds inside prisons for mental health and substance use purposes. The province has also expanded its Mental Health Act to allow longer involuntary hospitalization and compulsory treatment for people with substance use issues.

In March 2026, Québec introduced a bill allowing health data sharing and closer co-ordination between police and health services, with provisions to bypass consent for people deemed mentally “altered” or “distrustful” of institutions.

In all four provinces, professionals operating within these coercive frameworks are afforded immunity from legal proceedings.

‘Compassionate intervention’

These examples highlight an acceleration in overt coercive intervention provisions being added to provincial mental health and addictions legislation.

This acceleration, however, is simply a continuation of mental health and addictions legislation across Canada that makes it easier for citizens to be detained, treated and controlled without their consent (for example, Brian’s Law in Ontario, the Nunavut Mental Health Act and the Maureen Breau Act in Québec).

Across Alberta, Manitoba, British Columbia and Québec, parliamentary debates and media coverage consistently portray coercive intervention for addiction and mental health as an act of compassionate intervention.

Even governments with differing ideological orientations — like the NDP versus the Conservatives — converge around the argument that the state has a moral obligation to “protect the most vulnerable.”

This is especially true for people deemed incapable of making rational decisions due to severe addiction or mental health. In legislative debates, the notion of compassion is reinforced through narratives of urgency and failure. Existing harm-reduction strategies are described as insufficient or outdated, necessitating a decisive shift toward more interventionist models.

A disregard for science and ethics

Media coverage amplifies this messaging, emphasizing crisis conditions, public disorder and the visible consequences of addiction or mental health. This coverage legitimizes the need for new legal tools.

Coercion is articulated as care and involuntary treatment is presented not as a restriction of liberty but as a necessary response to incapacity and risk.

This appeal to compassion functions as a unifying political language, enabling cross-partisan support despite differing ideological stances.

By portraying these policies as pragmatic, humane and long overdue, policymakers limit opposition. They also reconfigure the boundaries of acceptable state intervention, illustrating how compassion can be mobilized to normalize coercion. After all, who could be against compassion?

This rhetorical focus on compassion allows governments to sidestep deeper ethical and empirical critiques, including the limited scientific evidence supporting forced treatment and the potential harms associated with it.

In fact, whether administered in closed settings or in the community, there is a striking lack of robust evidence, including an absence of Canadian research, that demonstrates clinical benefits. Instead, research points to significant adverse effects, including deaths due to forced treatments for opiate use, raising serious ethical concerns.

Police-medicine hybridization

Furthermore, this compassion-focused public discourse — and the legislation flowing from it — greatly expands the role of policing in medical matters, often with few limits. At the same time, it extends the reach of medicine and social services into policing.

This growing police–medicine hybridization is concerning for everyone, but especially for groups that have long faced disproportionate psychiatric coercion, including women and Black, Indigenous and other racialized communities.

It also signals a modern return of the asylum — not as a single institution, but as a system of confinement, surveillance and control spread across multiple sectors. Indeed, despite being presented as new, recent and proposed legislative changes are anything but. Forced detention, incarceration and treatment reflect older, deeply rooted correctional approaches with origins dating back at least to the 17th century.

These legislative developments do not suggest a novel policy response. Instead, they reconfigure longstanding patterns of confinement and control under the guise of compassion. If left unchallenged, they will normalize coercion as care and erode fundamental rights in the name of protection.

Canadian legislators should resist responding to complex social and health crises with coercive measures that lack a sound scientific basis and risk doing more harm than good.

Soil monitoring: what the new EU-wide ‘ground rules’ have in store for Europe

Source: The Conversation – France – By Mickaël Hedde, Directeur de recherche, Inrae

The European soil monitoring directive, adopted by the European Union at the end of 2025, aims to achieve healthy soils by 2050. Brussels’ directive is centred on an environmental DNA based approach. France’s experience in measuring soil quality could be used advantageously, particularly as the best monitoring tools are those that integrate several complementary approaches at the same time.

Since November 2025, the European Soil Monitoring and Resilience Directive requires member states to regularly assess soil biodiversity. It calls for soil microbial diversity analysis (bacteria and fungi) at six year intervals based on environmental DNA or “eDNA”.

Yet, while eDNA is a powerful tool for detecting biodiversity at scale, it is not enough on its own for interpreting observed changes and identifying their causes. This is because bacterial and fungal communities only represent part of the soil biodiversity, which also includes many organisms with crucial and varied ecological roles.

Abundance, biomass and the activity of living organisms – dimensions that cannot be assessed by molecular detection alone also determine how soils function. A graduated approach combining several complementary protocols is therefore required to produce robust and useful indicators for field work.

France’s track record via its soil quality measurement network (Réseau de Mesures de la Qualité des Sols (RMQS) and GIS Sol, constitutes, as such, a benchmark for interpreting results and an established operational framework for monitoring soil biodiversity. This could usefully complement the basis of the European legislation.

Environmental DNA: necessary but not sufficient

DNA works with a molecular approach and, as such, offers advantages in environmental monitoring in other words – broad and standardised biodiversity analysis, strong spatial and temporal comparability. Such methods provide a particularly effective tool for detecting changes in the composition of biological communities.

However, the molecular signatures derived from eDNA do not always allow us to correctly identify the taxa that is present in soil. They may show representativeness biases. They are often poorly correlated with other biological characteristics that are essential for characterising biodiversity and soil ecosystem functioning, such as the abundance of organisms, their biomass, their demographic structure or even their activities. They will thus offer an incomplete and sometimes distorted view of soil health.

However, beyond the simple detection of changes in diversity, monitoring devices must also make it possible to interpret these developments, that is to say, to understand what they imply for soil functionality in agriculture, for example, and to identify their causes. This is what will allow us to assess the effectiveness of public policies and management practices. In this context, reducing biological and ecological soil complexity to this single component carries a risk related to interpretation difficulties.

However, the EU directive stipulates that member states may supplement mandatory indicators with other biological indicators in their national monitoring arrangements, thus opening up the possibility of more integrated approaches.

A support tool for policymaking

Environmental monitoring has two distinct and complementary objectives: detecting changes in the state of ecosystems and attributing these changes to environmental pressures, land uses or management practices. These two dimensions are closely linked by the biological and ecological processes that structure how ecosystems function.

Beyond their scientific scope, the indicators used for monitoring soil biodiversity are instrumental in public decision-making. It is not only a question of identifying the dynamics within biological communities, but also understanding their causes. Therefore, this primarily concerns policymakers. The aim is to guide planning and sustainable management practices, identify situations presenting degradation, implement policies to remedy them, and be able to assess their effectiveness.

A monitoring system that would be limited to detecting changes in soil biodiversity without taking into account interpretation and attribution related to environmental pressures would provide a limited basis for evaluating public policies and the implementation of suitable management strategies.

Biodiversity is not just about the number of taxa

Ecological soil functions – such as regulating water and contaminants, providing nutrients, storing carbon, maintaining structure, or supporting biodiversity itself are not static states, but dynamic processes. They are based on the activity of living organisms, their biomass and their functional characteristics (physiology, behaviour), as well as their interactions (competition, symbiosis, parasitism). They are expressed through renewal flows and speeds rather than mere stocks.

In this context, molecular approaches provide valuable information on the presence of organisms, but by themselves do not allow us to assess these dynamic processes or their actual intensity. A correct interpretation of soil functioning therefore requires additional measures as well as interpretation references linking biological indicators to different land use contexts and environmental conditions.

eDNA data is increasingly used for developing new approaches, such as those based on interaction networks, which show how biological soil communities are organised. When these networks are built only on presence or co-occurrence data, they mainly reflect how ecological conditions or environmental niches are shared by different species.

This only provides indirect information on the biological activities at work and on matter and energy flows, which also determine soil functioning. Ecological interpretation requires additional information, particularly on the abundance or biomass of organisms. This is how biological communities can be linked to the ecological processes supporting soil functions.

A graduated and complementary approach

In order to reconcile operational efficiency and ecological relevance, soil biodiversity monitoring benefits from combining several types of approaches, each providing specific information on the condition and functioning of biological communities.

eDNA-based approaches enable broad and standardised detection of microbial biodiversity, and could be extended to other organisms, such as invertebrates.

Other methods are based on direct observation of soil fauna organisms, estimation of their abundance or biomass, or analysis of their functional characteristics. They provide essential information on the biological structure and ecological role of soil communities.

These approaches should not be seen as mutually exclusive, but as complementary tools. They allow us to link the composition of biological communities (taxonomic and functional structure) to the ecological processes that support soil functions. Their combination is, as such, particularly interesting for building a monitoring strategy with different levels of information.

This logic of complementary is already implemented in some existing monitoring tools as it the case in the framework of France’s national soil monitoring network (RMQS) or in the mountain biodiversity observatory Orchamp. These approaches are not meant to be deployed everywhere, but their combination is essential for correctly interpreting the condition and evolution of soil biodiversity.

Suggested guidelines for national implementation of the EU directive

Preserving our ability to understand, explain and take action requires us to recognise that the biological complexity of soils calls for a controlled diversity of monitoring approaches.

With the support of GIS Sol, France is among the nations at the forefront of soil biodiversity monitoring. It has been experimenting with this approach, combining several protocols within RMQS for several years. This experience, which is rare on a European scale, should be the basis for building the country’s future national soil monitoring network.

In addition to the mandatory indicators, the directive enables member states to supplement their own systems with optional indicators. This flexibility gives them the opportunity to set up a monitoring system that’s not only capable of detecting trends in changing soil biodiversity, but interpreting the causes and possibilities for remediation. This finally allows us to assess the implications for public policy.

With this in mind, several principles should be taken into consideration when implementing the EU directive at national level:

  • Do not restrict national soil biodiversity monitoring to a single eDNA-derived measure, which limits our ability to interpret observed changes.

  • Implement a combination of complementary measures in order to link the detection of biodiversity to community structure and ecological processes that support soil functions, with the support of protocols and measures developed across Priority Research Programmes and Equipments (PEPR) Dynabiod and SolsVivants in France, for example.

  • Develop open interpretation frameworks and analytical frameworks to assess whether the observed variations are significant, in order to link biological indicators to land uses and environmental pressures.

  • Take advantage of existing analysis mechanisms, in particular France’s soil quality measurement network supported by GIS Sol, to ensure consistency, comparability and the scientific robustness of any given future national monitoring system.
