Catastrophes industrielles, ferroviaires, maritimes… L’erreur individuelle existe-t-elle vraiment ?

Source: The Conversation – France in French (2) – By Chauvin Christine, Professeur en ergonomie cognitive, facteurs humains, Université Bretagne Sud (UBS)

L’erreur humaine est considérée comme un facteur déterminant dans la survenue d’accidents majeurs. Elle a été ainsi désignée comme une cause principale dans le naufrage du « Titanic », l’explosion de l’usine de pesticide de Bhopal, l’explosion du réacteur de Tchernobyl ou encore la collision aérienne de Tenerife. Lorsque de tels accidents surviennent, les médias mettent souvent en exergue l’erreur commise par l’équipe ou l’opérateur qui pilotait le système et l’associent parfois à la responsabilité individuelle d’une personne. Est-ce vraiment pertinent ?


Prenons l’exemple de la collision frontale entre un train de voyageurs et un convoi de marchandises survenue en Grèce, dans la nuit du 28 février au mercredi 1er mars 2023. Faisant 57 morts et 81 blessés graves, c’est l’accident ferroviaire le plus meurtrier qu’a connu la Grèce. Dans un article paru le 1er mars, le lendemain de la catastrophe, le journal le Monde titrait Accident de train en Grèce : le premier ministre pointe « une tragique erreur humaine », puis précisait plus loin que le chef de la gare de Larissa avait été arrêté et était poursuivi pour « homicides par négligence ».

Deux trains avaient circulé pendant plus de dix minutes sur la même voie, en sens opposé, sans qu’aucun système d’alarme ne soit déclenché avant la collision. Le rapport d’enquête rédigé par la HARSIA (Hellenic Air & Rail Safety Investigation Authority, l’équivalent du Bureau d’enquêtes sur les accidents de transport terrestre en France ou BEA-TT), publié le 27 février 2025, montre que la cause immédiate de l’accident est une erreur d’aiguillage. Le train de passagers IC 62 en provenance d’Athènes aurait dû rester sur la voie principale (ascendante), mais le chef de gare orienta l’aiguillage vers la voie descendante qui était occupée par un train de fret venant en sens inverse.

Malheureusement, le chef de gare ne détecta pas cette erreur et il n’y eut pas de communication claire avec le conducteur du train qui aurait permis de l’identifier. En effet, le chef de gare donna un ordre ambigu qui ne mentionnait pas la voie qu’allait emprunter le train. Le conducteur aurait dû répéter l’ordre en demandant au chef de gare de préciser la voie (ascendante ou descendante). Il s’agit de la procédure dite de « readback/hearback » qui consiste à répéter et à confirmer chaque instruction critique pour éviter tout malentendu. De plus, le conducteur aurait dû contacter le chef de gare lorsqu’il a constaté qu’il ne se trouvait pas sur la voie montante.

Le rapport met en évidence les circonstances dans lesquelles cette erreur a été commise (notamment la charge de travail élevée du chef de gare, un pupitre de contrôle comportant de nombreuses commandes et informations). De plus, il fait ressortir les défaillances du système ferroviaire grec comme constituant des facteurs sous-jacents (infrastructure dégradée et insuffisamment entretenue, sous-effectif chronique, absence de maintenance préventive des dispositifs de contrôle-commande et de la signalisation, problème de formation et de gestion des compétences des personnels, défaillance du système de communication, absence de retour d’expériences qui aurait permis d’apprendre des incidents et accidents passés).

Les auteurs de ce rapport n’examinent donc pas seulement les activités du chef de gare et du conducteur de train ; ils s’intéressent aussi aux décisions d’acteurs institutionnels : la compagnie ferroviaire chargée de l’exploitation des trains, l’entreprise publique gestionnaire du réseau ferré et, donc, l’État.

Cet accident a entraîné de nombreuses manifestations en Grèce ; les manifestants pointant les dysfonctionnements du réseau ferroviaire. Le chef de gare de Larissa a été le premier à être placé en détention provisoire, puis trois autres employés des chemins de fer ont été poursuivis pour « homicide involontaire par négligence ». Le 15 septembre 2025, le procureur d’appel de Larissa a demandé, à l’issue d’un rapport de 996 pages, que 33 autres personnes soient renvoyées devant la cour d’assises. Il s’agit d’acteurs opérationnels ou administratifs responsables de la sécurité ferroviaire.

Cet exemple montre qu’il est important, lors d’un accident majeur, d’opérer un déplacement de point de vue :

  • ne plus se focaliser sur l’opérateur, mais examiner l’ensemble des éléments qui compose le système au sein duquel il opère ;

  • ne plus se focaliser sur l’action ou sur la décision d’un opérateur « de première ligne », mais considérer l’impact des décisions prises à tous les niveaux d’une organisation.

Erreur humaine ou défaillances systémiques ?

Nombre de travaux menés depuis la Seconde Guerre mondiale invitent à considérer une action erronée non pas comme une action fautive, mais comme le symptôme d’une mauvaise adéquation entre les capacités de l’opérateur et les caractéristiques de sa situation de travail.

En 1990, le psychologue anglais James Reason publie un ouvrage de référence intitulé Human Error dans lequel il distingue les « erreurs actives » et les « erreurs latentes » ou « conditions latentes ». Les premières ont un effet immédiat. Il s’agit d’actions « erronées » commises par les opérateurs « de première ligne ». Les secondes sont présentes au sein du système depuis parfois de nombreuses années, mais sont « dormantes ». Elles se développent à partir d’activités humaines éloignées de l’activité qui déclenche le dommage (activités de conception, de maintenance, management). C’est en se combinant à d’autres facteurs qu’elles se révèlent et contribuent à l’accident.

Nous avons utilisé ce cadre pour analyser des collisions entre navires. L’analyse menée fait apparaître trois grandes classes d’accidents.

La première classe est typique d’accidents qui surviennent dans des eaux dites « resserrées » (des chenaux principalement) alors qu’un pilote se trouve à bord du navire. Les principaux facteurs d’accidents sont des problèmes de communication (entre navires et au sein de l’équipage). Ce résultat met en exergue l’importance des formations au travail d’équipe, tout particulièrement pour les situations dans lesquelles un pilote doit interagir avec le commandant et l’équipage du navire. Ce facteur fait écho à l’ambiguïté de la communication entre le chef de gare et le conducteur de train qui participa à la collision ferroviaire de Larissa.

La deuxième classe d’accidents résulte de l’interaction de facteurs appartenant à différents niveaux du système : mauvaise visibilité et non-utilisation ou mauvaise utilisation des instruments, planification d’opérations inappropriées à la situation – comme une vitesse excessive au regard des conditions extérieures ou un nombre insuffisant de personnes affectées à la tâche (facteurs relevant du leadership), système de management de la sécurité incomplet (facteur organisationnel).

La troisième classe d’accidents se caractérise, quant à elle, par le non-respect du système de management de la sécurité ; il s’agit, dans ce cas, de violations (erreurs intentionnelles) relevant du leadership.

De l’analyse des erreurs à l’analyse des décisions

Jens Rasmussen, qui fut l’un des chercheurs les plus influents dans le domaine de la sécurité et de l’étude de l’erreur humaine, explique que la notion d’erreur (supposant un écart à une performance définie) n’est pas vraiment pertinente, parce qu’elle entre en contradiction avec la capacité d’adaptation humaine, avec le fait que les acteurs – au sein d’un système – ont une certaine liberté dans la façon de réaliser leur activité et peuvent ainsi opter pour différentes stratégies.

Adaptation et variabilité sont même nécessaires pour garantir la performance des systèmes. S’intéressant aux interactions « verticales » au sein d’une organisation, Rasmussen propose d’identifier tous les acteurs (acteurs étatiques, législateurs, syndicats, concepteurs de système, dirigeants d’entreprises, managers, opérateurs) dont les décisions ont contribué à l’accident ; il souligne que les contraintes et possibilités qui s’imposent à un acteur donné et à un niveau donné dépendent de décisions prises par d’autres acteurs.

Dans le secteur de la pêche maritime, il est intéressant d’analyser l’impact des décisions prises par les législateurs (au niveau national et international) sur les choix réalisés par les concepteurs des navires et des équipements et, finalement, sur les pêcheurs eux-mêmes. Ainsi plusieurs études ont examiné l’impact, sur la sécurité des marins-pêcheurs, du type de quotas de pêche (quotas individuels qui donnent à un opérateur le droit de prélever une quantité déterminée de poissons sur un stock ou quotas collectifs). D’une façon générale, l’allocation individuelle de quotas réduit la « course au poisson » et diminue les prises de risque.

Dans la lignée de ces travaux, nous avons montré que la législation impose aux marins-pêcheurs des contraintes qui ont une forte incidence sur leurs décisions, sur les arbitrages qu’ils font au quotidien et sur la prise de risque.

Il est nécessaire d’adopter une perspective systémique pour comprendre la survenue des accidents. Dans ce cadre, il apparaît plus pertinent de s’intéresser aux décisions des différents acteurs d’un système, et aux interactions entre ces décisions, qu’aux erreurs qu’ils peuvent commettre.

El Nobel que rima con la historia: del vapor a la inteligencia artificial

Source: The Conversation – (in Spanish) – By Luis Garvía Vega, Director del Máster Universitario en Gestión de Riesgos Financieros (MUGRF) en ICADE Business School, Universidad Pontificia Comillas

Un año más, conviene leer entre líneas lo que dicen desde el Riksbank. Los Nobel de Economía nunca se conceden solo por lo que premian, sino también por lo que insinúan. Detrás de cada elección hay un mensaje subliminal: cuando galardonaron a Ben Bernanke, en 2022, el trasfondo era la política monetaria y las crisis financieras. Cuando en 2023 premiaron a Claudia Goldin, historiadora del trabajo, el foco estaba en la evolución del papel de la mujer en la economía. Este año, al reconocer a Joel Mokyr, Philippe Aghion y Peter Howitt, el acento vuelve al motor del progreso: la innovación.

Como recordaba Mark Twain, la historia no se repite pero rima. Y este Nobel, apoyado en historiadores del crecimiento y arquitectos de la destrucción creadora, rima poderosamente con el momento que vivimos.

Confianza en el progreso

Joel Mokyr es mucho más que un historiador económico: es un arqueólogo de las ideas que hicieron posible el progreso. Profesor en Northwestern University, lleva décadas escarbando en los cimientos intelectuales de la Revolución Industrial, preguntándose no solo qué ocurrió, sino por qué ocurrió allí y entonces.

En obras como The Lever of Riches o A Culture of Growth, Mokyr sostiene que el verdadero motor del desarrollo no fueron las máquinas sino las mentes. Europa despegó, recuerda, cuando cambió su actitud hacia el conocimiento e inventores, científicos y artesanos comenzaron a hablar un mismo idioma: el de la curiosidad, la evidencia y la confianza en el progreso.

Su mensaje tiene hoy un eco especial en el Viejo Continente: Europa ya fue cuna de una revolución industrial gracias a su cultura abierta, crítica y colaborativa. Podría volver a serlo si convierte la inteligencia, humana y artificial, en su nueva materia prima. Mokyr nos recuerda que la tecnología no nace del vacío, sino de un ecosistema cultural que confía en la razón y tolera el error. Y que el optimismo no es ingenuidad, sino una forma de fe en la capacidad creativa del ser humano.

Que surja lo nuevo

Si Mokyr nos recuerda de dónde venimos, Philippe Aghion y Peter Howitt nos explican hacia dónde vamos. Discípulos intelectuales de Joseph Schumpeter, transformaron su intuición sobre la destrucción creadora en una teoría rigurosa del crecimiento económico.

Su modelo, que hoy forma parte del ADN de la economía moderna, describe cómo las nuevas ideas, al irrumpir, desplazan a las antiguas y abren espacio para el progreso. No se trata de destruir por destruir, sino de dejar morir lo que ya no sirve para que surja lo nuevo: la esencia misma del emprendimiento.

Aghion, desde el Collège de France, insiste en que las economías dinámicas son aquellas que premian la innovación y toleran el riesgo, mientras Howitt, desde Brown University, ha mostrado cómo esa dinámica se traduce en bienestar a largo plazo. En tiempos de revolución tecnológica, su mensaje es claro: no hay crecimiento sin cambio, ni innovación sin valentía. Europa, que un día lideró el espíritu emprendedor de Schumpeter, necesita recuperar esa audacia: convertir su prudencia en impulso, su regulación en confianza, y su miedo a perder en deseo de crear.

El comunicado oficial del Riksbank lo resume con una claridad que trasciende lo académico:

“Por haber explicado el crecimiento económico impulsado por la innovación, con una mitad a Joel Mokyr por haber identificado los prerrequisitos para un crecimiento sostenido mediante el progreso tecnológico, y la otra mitad a Philippe Aghion y Peter Howitt por la teoría del crecimiento sostenido a través de la destrucción creativa”.

Ideas, energía poderosa

En una sola frase, el premio conecta pasado y futuro: la cultura del conocimiento que permitió la Revolución Industrial y el dinamismo emprendedor que impulsa el cambio tecnológico actual. Mokyr nos recuerda que sin un clima intelectual abierto no hay inventos que prosperen, y Aghion y Howitt que sin competencia y renovación no hay progreso que dure.

El Nobel de 2025 no es solo un homenaje a tres economistas brillantes, sino un recordatorio para nuestro tiempo: las ideas siguen siendo la energía más poderosa de la humanidad. Europa, que una vez encendió la chispa del vapor y del pensamiento crítico, tiene ante sí la oportunidad de hacerlo de nuevo, esta vez con la inteligencia, humana y artificial, como su nuevo motor de crecimiento.

3-legged lizards can thrive against all odds, challenging assumptions about how evolution works in the wild

Source: The Conversation – USA – By James T. Stroud, Assistant Professor of Ecology and Evolution, Georgia Institute of Technology

We are lizard biologists, and to do our work we need to catch lizards – never an easy task with such fast, agile creatures.

Years ago, one of us was in the Bahamas chasing a typically uncooperative lizard across dense and narrow branches, frustrated that its nimble agility was thwarting efforts to catch it. Only when finally captured did we discover this wily brown anole was missing its entire left hind leg. This astonishing observation set our research down an unexpected path.

That chance encounter led us to collaborate with over 60 colleagues worldwide to document what we suspected might be a broader phenomenon. Our research uncovered 122 cases of limb loss across 58 lizard species and revealed that these “three-legged pirates” – the rare survivors of traumatic injuries – can run just as fast, maintain healthy body weight, reproduce successfully and live surprisingly long lives.

To be clear, most lizards probably do not survive such devastating injuries. What we’re documenting are the exceptional cases that defy our expectations about how natural selection works.

Christopher Anderson

This discovery is startling because lizard limbs represent one of biology’s most studied examples of evolutionary adaptation. For decades, scientists have demonstrated that even tiny differences in leg length between individual lizards can mean the difference between life and death – affecting their ability to escape predators, catch prey and find mates.

Since subtle variations matter so much, biologists have long assumed that losing an entire limb should be catastrophic.

Yet our global survey tells a different story about these remarkable survivors. Working with colleagues across six continents, we found limb-damaged lizards across nearly all major lizard families, from tiny geckos to massive iguanas.

These animals had clearly healed from whatever trauma caused their injuries – likely accidents or the failed attempts of a predator to eat them. Perhaps most remarkably, we documented surviving limb loss even in chameleons, tree-climbing specialists whose movements seem to require perfect limb coordination.

Thriving, not just surviving

The body condition of these lizards was most surprising. Rather than appearing malnourished, many limb-damaged lizards were actually heavier than expected for their size, suggesting they were successfully finding food despite their handicap. Some were actively reproducing, with females found carrying eggs and males observed successfully mating.

Jason Kolbe/Jonathan Losos

These findings force us to reconsider some basic assumptions about how evolution might work in wild populations. Charles Darwin envisioned natural selection as an omnipresent force, “daily and hourly scrutinizing” every feature.

But perhaps selection is more episodic than constant. Maybe sometimes limb length matters tremendously, while during other times – such as when food is abundant and predators are scarce – limb length matters less and three-legged lizards can flourish.

These lizard survivors showcase the incredible solutions that millions of years of evolution have built into their biology. Rather than being passive victims of their injuries, these lizards may survive by actively choosing safer habitats or hunting strategies, using smart behavior to avoid situations where their disability would be a disadvantage.

Biological engineering in action

Our research combines old-fashioned natural history observations with cutting-edge, biomechanical analysis.

We use high-speed cameras and computer software that can track movement frame by frame to analyze running mechanics invisible to the naked eye. This combination of field biology and laboratory precision allows us to understand not just that these lizards survive, but how they accomplish this remarkable feat.

When we tested the three-legged lizards’ athletic performance, the results defied expectations. Some animals were clearly impaired in their sprinting capabilities, but others actually ran faster than fully-limbed individuals of the same size across a 2-meter dash during our “Lizard Olympics.”

Researchers used computer software that automatically tracks movement patterns to analyze high-speed videos of lizards sprinting, such as this brown anole missing half of its right back leg. Christopher Anderson

High-speed video analysis revealed their secret: The speedy survivors compensate through creative biomechanical solutions. One brown anole missing half its hind limb dramatically increased its body undulation during sprinting, using exaggerated snakelike movements to compensate for the missing leg.

By documenting the unexpected – the seemingly impossible survivors – we’re reminded that nature still holds surprises that can fundamentally change how we think about life itself.

Why are elements like radium dangerous? A chemist explains radioactivity and its health effects

“What is radium and why is it dangerous?” – Aurora, 10, Laredo, Texas


The element radium can be found in extremely tiny amounts in the Earth’s crust and oceans, and in its pure form it is a soft silvery metal. To an untrained eye, a small piece of radium may look like a chip off a regular gray rock. But radium can invisibly emit radiation – energy and small fragments of itself – that you can’t feel, see or smell. And that invisible radiation can hurt you, without you even noticing right away.

What’s going on with this silent threat that can stealthily damage your body in ways that can take years to reveal themselves?

As a chemist, I’m interested in what makes different elements safe to handle or hazardous. This dangerous release of radiation is called radioactivity, and even though its source may look unassuming, it can burn you or even give you diseases that don’t manifest for years.

Atoms and isotopes

Everything you see around you – your skin, rocks, the pages of books – is all made up of different combinations of extremely small particles called atoms.

An atom has a small, dense center called the nucleus. Negatively charged particles called electrons move around the nucleus. Inside the nucleus, there are two types of particles: positively charged protons and neutral neutrons.

All atoms with the same number of protons in their nuclei are the same element. Besides radium, some elements you may have heard of are carbon and oxygen. All carbon atoms have six protons and all oxygen atoms have eight protons. Radium atoms are much heavier – all radium atoms have 88 protons.

Interestingly, it is possible for atoms of the same element to have different numbers of neutrons. Atoms of the same element with different numbers of neutrons are called isotopes. For instance, two carbon atoms would each have six protons, but one might have six neutrons while another could have seven or eight.

The number of protons and neutrons packed together in the nucleus determines whether the nucleus of an isotope is stable or not. If the nucleus is not stable, problems can arise.

Radioactive decay

The nucleus of each atom wants to be stable, but only certain arrangements of protons and neutrons make that possible. The number of protons and neutrons do not have to be equal, but some combinations make for a happy, or stable, coexistence in the nucleus while others don’t.

A nucleus with an unhappy mix of protons and neutrons might break down or deteriorate in some way. That process is called radioactivity or radioactive decay.

Elements are radioactive if they decay by releasing parts of the nucleus or high-energy particles.

That radioactive decay process releases some form of radiation from the nucleus. This radiation can take the form of tiny particles moving rapidly or high-energy electromagnetic waves emerging from the nucleus. It is that radiation – the high-energy particles and waves shooting out from the nucleus of unstable atomic nuclei – that can make you sick.

There are different types of radioactive decay. In one case, an atom decays by kicking out a small fragment of itself that is made up of two protons and two neutrons. Since the number of protons determines what element we have, decay that changes the number of protons in an atom turns it into a different element.

Radioactive decay can be quite slow, though. It can take thousands of years for one element to decay into a different one.

The case of radium

All radium atoms are unstable and radioactive. Many of these isotopes decay very quickly, but Ra-226, which has 138 neutrons and 88 protons and is the most common, decays the slowest. It takes 1,600 years for half a sample of Ra-226 to decay.

Radium undergoes alpha decay, where it loses a fragment of its nucleus containing two protons and two neutrons, after which it becomes radon.

As Ra-226 decays, it loses two protons and two neutrons, which turns it into an isotope of radon. Then the radon decays, and the atom eventually reaches a stable form as the element lead. Each step in that decay series releases more nuclear radiation.

Some other elements in nature with no stable isotope are technetium, polonium, actinium and uranium.

Effects on the human body

The nuclear radiation emitted when radium and other elements decay can damage the cells in the human body. It can lead to cancers or other health problems.

Marie and Pierre Curie experimented with radium, which ended up causing health complications for them.
André Castaigne

Whether you’re exposed to a lot of radiation quickly, like making the mistake of walking around for a few hours with radioactive material in your pocket, or you’re exposed to just a little over a long time, the high-energy particles and electromagnetic waves from nuclear radiation can lead to serious health problems, including burns and cancers.

Remarkably, even though radioactivity is a threat to life, scientists can control and use it to diagnose and treat diseases – including cancers. If the radiation is delivered precisely to where cancer cells are, the radiation can destroy those rogue cells wreaking havoc in the body.

People who work professionally with radioactive materials need to follow strict guidelines and procedures to protect themselves. They use special shields and radiation detectors, and they minimize the amount of time they’re exposed to any radioactivity.

Pierre and Marie Curie, who discovered radium in 1898, suffered some of the negative effects of radioactivity. Pierre experienced radioactive burns, and Marie died from a blood disease likely caused by chronic radiation exposure. Over 100 years later, her notebooks are still radioactive.

Far fewer Americans support political violence than recent polls suggest

Source: The Conversation – USA – By Ryan Kennedy, Timashev Chair of Data Analytics and Professor of Political Science, The Ohio State University

Some surveys have reported that a large number of Americans are willing to support the use of force for political ends. stellalevi, DigitalVision Vectors/Getty Images

A series of recent events has sparked alarm about rising levels of political violence in the U.S. These episodes include the assassination of political activist Charlie Kirk on Sept. 10, 2025; the murder of a Democratic Minnesota state legislator and her husband in June 2025; and two attempts to kill Donald Trump during the 2024 presidential campaign.

Some surveys have reported that a large number of Americans are willing to support the use of force for political ends, or they believe that political violence may sometimes be justified.

My research is in political science and data analytics. I have conducted surveys for almost 25 years. For the past three years, I have studied new techniques that leverage artificial intelligence to conduct and analyze interviews.

My own recent surveys, which use AI to ask people about why they give their answers, show that the surprisingly high level of support in response to these questions is likely the result of confusion about what these questions are asking, not actual support for political violence.

A failure to communicate

Why would multiple surveys get the answers to this important question wrong? I believe the cause is an issue called response error. It means that respondents don’t interpret a question in the way the researcher thinks they will.

As a result, the answers people provide don’t really reflect what the researcher thinks the answers show.

For example, asking whether someone would support the use of force to achieve a political goal raises the question of what the respondent thinks “use of force” means in this context. It could be interpreted as violence, but it could also be interpreted as using legal means to “force” someone to do something.

Such response errors have been a concern for pollsters ever since survey research began. They can affect even seemingly straightforward questions.

What did you mean by that?

To avoid this problem, I used an AI interviewing system developed by CloudResearch, a well-known survey research company, to ask respondents some of the same questions about political violence from previous surveys. Then I used it to ask what they were thinking when they answered those questions. This process is called cognitive interviewing.

I then used AI to go through these interviews and categorize them. Two short reports that summarize this process as applied to both polls are available online. These analyses have not been peer-reviewed, and the results should be considered very preliminary.

Nonetheless, the results clearly demonstrate that respondents interpret these questions in very different ways.

Nuance matters

For example, in my survey, about 33% of Democrats agreed with the statement that “use of force is justified to remove President Trump from office.” However, when asked why they agreed, more than 57% gave responses like this: “I was not thinking physically but more in the sense that he – the president – might need to be ‘fired’ or forced out of office due to rules or laws.” Still others were envisioning future scenarios where a president illegally seizes power in a coup.

Once you account for these different interpretations of the question, the AI only coded about 8% of Democrats as supporting use of force in violent terms under current conditions.

Even here, there was substantial ambiguity – for example, this type of response was not unusual: “The language ‘use of force’ was a bit too broad for me. I could not justify killing Trump, for example, but less extreme uses of force were valid in my eyes.”

Similarly, 29% of Republicans agreed that “use of the military is justified to stop protests against President Trump’s agenda.” However, almost all of the respondents who agreed with this statement envisioned the National Guard interceding nonviolently to stop violent protests and riots. Only about 2.6% of Republicans gave comments supporting use of the military against nonviolent protests.

Almost all those who agreed that use of the military was justified expressed thoughts like this: “I see the military coming and acting as a police force to stop or prevent the demonstrations that become violent. Peaceful protesters must be allowed to exercise their right to free speech.”

When is political violence justified?

Even questions that explicitly ask about political violence are open to wide interpretation. Take, for example, this question: “Do you think it is ever justified for citizens to resort to violence in order to achieve political goals?”

The lack of a specific scenario or location in this question invites respondents to engage in all kinds of philosophical and historical speculation.

In my survey, almost 15% of respondents said violence could sometimes be justified. When asked about the examples they were thinking of, respondents cited the American Revolution, the anti-Nazi French Resistance and many other incidents as a reason for their responses. Only about 3% of respondents said they were thinking about actions in the U.S. at the current time.

Moreover, almost all respondents stated that violence should be a last resort when all other peaceful and legal methods fail.

One respondent illustrated both problems with one sentence: “The (American) colonists tried petitions and negotiations first, but, when those efforts failed, they resorted to armed conflict to gain independence.”

A call for understanding

Even these numbers likely overestimate Americans’ support for political violence. I read the interviews, checking the AI system’s labeling, and concluded that, if anything, it was overestimating support for violence.

Other factors may also be distorting reports of public support for political violence. Many surveys are conducted primarily online. One study estimated that anywhere from 4% to 7% of respondents in online surveys are “bogus respondents” who are selecting arbitrary responses. Another study reported that such respondents dramatically increase positive responses on questions about political violence.

Respondents may also be willing to espouse attitudes anonymously online that they would never say or do in real life. Studies have suggested that “online disinhibition effects” or “survey trolling” can impact survey results.

In sum, my preliminary research suggests that response error is a substantial problem in surveys about political violence.

Americans almost universally condemn the recent political violence they have witnessed. The recent poll results showing otherwise more likely stem from confusion about what the questions are asking than actual support for political violence.

How the National Trust’s art collections can shape meadow restoration

Source: The Conversation – UK – By Samuel Shaw, Lecturer in History of Art, The Open University

Ox-eye daises in Ismore meadow, Attingham Park, Shropshire. Samuel Shaw, CC BY-NC-ND

Earlier this year I found myself stood among a sea of swaying ox-eye daises in a floodplain meadow on the Attingham estate in Shropshire, on land owned by the National Trust. I noticed other plants growing here: the sunny yellows of meadow buttercup, the wine-reds of great burnet and the furry seed heads of meadow foxtail. The sounds of birds and insects bubbled in the background.

It felt like a thriving environment, but I knew that this meadow could be so much more. Floodplain meadows are hugely important spaces, supporting rare plant communities and providing food for animals to eat during the winter months.

The soils of floodplain meadows are recognised by scientists as an important carbon store, helping to slow floodwaters and absorb nutrients. Many remaining floodplain meadows have been managed in the same way for more than 1,000 years. However, such sites are rare and most meadows are in serious need of restoration.

The diversity and abundance of the plants and animals I encountered at Attingham did not indicate a flourishing ecosystem. While birds such as lapwing had been seen passing through the site, they not been encouraged to stay and breed. The quality of the soil was improving, but only slowly.

After leaving the meadow, I visited Attingham Park, the large house that lies at the heart of the estate. As an art historian with a keen interest in the history and visual cultures of natural sciences, I was hoping to make connections across the trust’s collections. I wanted to find objects in the house that related to what I had encountered in the meadows.

I wasn’t disappointed. Attingham’s collection is large and deep, encompassing paintings, ceramics, furniture, rare books and much more besides. Some objects relate specifically to the house and to the Berwick family who lived there, while others form part of a broader story.

Evidence of meadows and meadow ecosystems appears everywhere: in the famous paintings of cattle hanging on the walls, in the representation of grasses in an early 20th-century fan, and in the tiny beetles that adorned an Italian paperweight. In the delicate lithographic plates of a 19th-century guide to British birds, compiled by the ornithologist John Gould, I found the lapwings that had thwarted me in the meadow.

Perhaps the most interesting object I saw was the original Attingham Red Book. Created in 1798 by landscape gardener Humphry Repton, this red leather-bound book documented his plans for the estate, via a series of charming and clever before-and-after watercolours. Could Repton’s book help me understand how this meadow has changed over centuries, and how it might change again?

The art of meadow restoration

It can be tempting to divide the National Trust’s holdings and activities into natural heritage on the one hand, and cultural heritage on the other. But the trust’s highly significant art and cultural collections (what is found inside) can be used to draw attention to what is going on in the estates (what is found outside). The trust owns thousands of historic objects that can help engage audiences with the past, present and future of its natural spaces.

Since 2006, my colleagues at the Floodplain Meadows Partnership, an initiative at the Open University, have been working with conservation organisations and landowners to ensure that floodplain meadows are protected, restored and successfully managed. By feeding into government agricultural funding schemes such as the countryside stewardship higher tier, the partnership’s research supports sustainable farming and nature restoration across the UK.

Current partners include the National Trust which, as one of the UK’s largest landowners and with ambitious nature recovery targets, is uniquely placed to lead the way in meadow restoration. Together, we have identified 121 fields at English estates, including Attingham, that could be suitable for floodplain meadow restoration.

The trust’s current emphasis on people and nature, as laid out in its new ten-year strategy, hints at a certain nervousness over how to situate the organisation’s significant holdings of art, design and architecture. Yet there’s a strong argument for bringing cultural and natural heritage closer together. Historic objects, such as those I explored at Attingham, do not stand apart from nature restoration, but can stimulate and shape it.

For example, Repton’s Red Book designs directly tackle issues – such as how to manage rivers and their floodplains – that remain at the heart of the estate’s management. But Repton liked his rivers to be ample and majestic, cutting through the landscape cleanly, rather than meandering messily. This goes against what is needed to create thriving river habitats, such as those envisaged by Attingham’s current nature recovery project.

Looking through the Red Book and the collections at Attingham provides much more than a window into the past. These objects show how the past is still so entwined with the present, and how it may inform what we do in the future.

Samuel Shaw’s film, Inside Out: Restoring floodplain meadows at the National Trust.

My research at Attingham, as highlighted in the short film above, shows how art and visual culture can help us better understand and engage audiences with nature restoration. Art objects offer a fresh perspective on environmental debates, helping people to visualise complex ideas in ways that inspire, surprise and change the direction of conversations.

The restoration of key environments such as floodplain meadows may be led by scientists, but the arts nevertheless have an essential role to play.

‘Sex for rent’ is illegal in the UK. Why are thousands of people still affected?

Source: The Conversation – UK – By Chris Waugh, Lecturer in Sociology and Criminology, Manchester Metropolitan University

When Andrew (not his real name) lost his job during the COVID-19 pandemic, he turned to work as a courier. His days became a slog – cycling for hours in rain or shine, juggling Deliveroo, Uber Eats and JustEat.

Despite the grind, he couldn’t afford to rent even a single room in his city. After months of sofa surfing and crammed bunk-bed accommodation, a friend of a friend offered him a room at a rent he could actually manage.

The catch? He had to have sex with his new, live-in landlady once a week.

This is what’s known as a sex-for-rent arrangement: when someone offers free or discounted accommodation in exchange for sex. I’ve been studying the experiences of people in sex-for-rent arrangements, and will be publishing my findings over the coming year.

While such arrangements might come with a veneer of consent, research from the UK and US shows they are often exploitative and disempowering. They start with a power imbalance, usually economic, that allows one person to exploit another’s desperation for housing.

There is relatively little academic research on sex for rent in the UK. But what we do have so far is deeply concerning. A 2022 survey by campaign group Generation Rent estimated that over 200,000 women may have been offered free or discounted rent in exchange for sexual favours.

These offers sometimes appear on platforms like Craigslist or Facebook Marketplace, often couched in vague, euphemistic language: “reduced rent for suitable female tenant”, or “alternative arrangements can be discussed”.

Investigative journalism has shown that these ads typically target young women – especially students and those in insecure work.

While confirming that young women are heavily targeted, my ongoing research reveals how economically marginalised men are being exploited too. Through qualitative interviews with survivors of sex-for-rent, I am exploring how this exploitative practice occurs, who is targeted and why.

Participants like Andrew often work in the gig economy, where wages are low and unpredictable. Others are migrants with no access to benefits or housing assistance, making it near impossible to access stable accommodation. Their experiences of sex-for-rent are made worse by social stigma, masculine expectations of self-reliance and a lack of tailored support.

What I have found so far supports and expands on findings already established in existing research, which has found how sex-for-rent is advertised to young women online, and becoming a regular part of an insecure housing market.

Survivors told me that landladies as well as landlords were engaging in sexual exploitation via sex-for-rent. Landlords were often aware of participants’ financial struggles and framed the arrangement as “helping them out”. Participants who tried to leave said they were threatened with eviction – both legal and illegal – to trap them.

The 15 men I spoke to reported intense feelings of shame, degradation and emasculation. They were also often unaware of support services that might be able to help them, including housing charities or services for male victims of sexual violence. Many feared legal consequences, wrongly believing they had broken the law by “prostituting themselves” and doubted police would believe them.

The limits of the law

Sex-for-rent is technically illegal under the Sexual Offences Act 2003, which states that sex-for-rent amounts to “controlling or inciting prostitution for gain”. Yet only two successful prosecutions have occurred – Christopher Cox in 2022 and Frederick Allyard in 2024.

It is unclear whether any further attempted prosecutions have occurred. But my research indicates that victims broadly believe that they themselves have committed an offence, rather than their landlords, grounded in the wrongful belief that sex work is a crime – it isn’t a crime to sell sex anywhere in the UK.

What is illegal is soliciting, brothel keeping and pimping, though these concepts are poorly defined in British law.

In 2023, the Home Office launched an open consultation on exchange of sexual relations for accommodation. While this is a welcome recognition of the issue, the consultation largely frames sex-for-rent as a matter of individual criminal landlords. It says little about why such exploitation persists – or how social conditions actively enable it.

Landlords hold far more power than tenants in the UK. Rents are among the highest in Europe, with projections suggesting that 2.2 million working adults could be priced out of the rental market by 2030.

The UK average rent is £1,339 per month, a more than 100% increase compared to ten years ago. People on lower incomes can spend up to 59% of their monthly wages on rent alone.

At the same time, wages have stagnated, housing benefit is inadequate, and those with insecure immigration status are locked out of public support entirely. Tenants begin from a position of reduced power, in a housing system that gives more power to the interests of landlords.

This system can be taken advantage of by predatory landlords, either through exploitation like sex-for-rent, or not keeping properties in liveable conditions.

Even if there were more prosecutions for sex-for-rent, it wouldn’t solve the problem alone. We can’t just focus on individual acts of criminality – sex-for-rent is the outcome of structural inequalities in housing, made possible by policy choices: the erosion of social housing, the deregulation of the private rental sector, the rise of precarious work and punitive immigration controls.

Properly addressing the problem would require more secure, affordable housing, an end to no recourse to public funds conditions and support services for all victims of sexual exploitation, not just women.

Over a decade of austerity has left many of these services hanging on by a thread. The current government could do worse than to reverse these trends. Sex-for-rent is not a fringe issue. It is a symptom of how deeply our housing and welfare systems have failed – and it demands a response as structural as the harm itself.

Does resistance training really improve your gut microbiome?

Source: The Conversation – UK – By Rosie Young, PhD Candidate, Gut Microbes in Health and Disease, Quadram Institute

Burnt Red Hen/Shutterstock.com

Lifting weights just two or three times a week can significantly change the trillions of bacteria living in your gut, and it might happen in as little as eight weeks.

That’s according to a recent study – not yet peer-reviewed – finding that previously inactive people who began resistance training showed notable changes in their gut microbiome, the community of microbes living in the digestive system.

Your gut is home to bacteria, fungi, viruses and other microscopic organisms, most of which live in the large intestine. These microbes help break down food that your body can’t digest on its own, allowing you to access more nutrients and vitamins.

Some bacteria are considered beneficial because they’re often found in people who are healthy, both physically and mentally. They produce compounds that appear to support wellbeing.

The makeup of your gut microbiome isn’t fixed. It changes based on factors such as what you eat, how old you are, how well you sleep – and, as this study shows, whether you exercise.

Researchers at the University of Tübingen in Germany recruited 150 people who didn’t normally exercise and asked them to do resistance training two to three times a week for eight weeks. Participants used either lighter weights with more repetitions (15 to 20) or heavier weights with fewer repetitions (eight to ten).

Both approaches produced similar improvements in strength and body composition. The exercises included chest presses, abdominal work, leg curls, leg presses and back exercises – two sets of each.

The researchers collected stool samples at the start of the programme, after four weeks and after eight weeks to track changes in participants’ gut bacteria.

Some people gained strength much faster than others. The researchers divided participants into “high responders” – the top 20%, who increased their strength by more than 33% on average – and “low responders” – the bottom 20%, who gained less than 12.2%.

The biggest factor determining whether someone was a high or low responder appeared to be their initial strength level.

But the researchers also found something interesting: the people who gained the most strength showed subtle but significant changes in their gut bacteria that the others didn’t.

High responders showed increases in 16 types of bacteria and decreases in 11 others. Two bacteria in particular stood out: Faecalibacterium and Roseburia hominis.

Both produce butyrate, a type of compound called a short-chain fatty acid. These compounds are created when gut bacteria break down fibre, and they serve multiple purposes: they provide energy for the body and help maintain a healthy gut lining, which prevents harmful bacteria from entering the bloodstream.

Similar increases in these bacteria have been found in other studies looking at exercise and the gut. However, in this study, the researchers didn’t find an actual increase in short-chain fatty acids in the stool samples – only more of the bacteria that produce them.

Not that simple

It’s tempting to label certain bacteria as “good” or “bad”, but it’s not that simple. Throughout the study, some bacteria typically associated with good health decreased, while others previously linked to poor health increased.

This highlights an important point: everyone’s microbiome is unique. The same bacteria might perform different roles in different people, depending on the individual and their overall health.

We also can’t say for certain whether the changes in gut bacteria caused the strength gains, or whether getting stronger caused the bacterial changes. Studies like this can show associations, but they can’t prove cause and effect – the microbiome is influenced by too many factors to control them all.

Diet, for instance, has a major effect on gut bacteria. Participants were told not to change their eating habits during the study, but it’s extremely difficult to accurately track what people eat.

It’s possible that some high responders changed their diet as they became more focused on fitness, and this could have contributed both to their bacterial changes and their strength gains.

What we can say with more confidence is that exercise appears to benefit overall physical and mental health and should be part of a healthy lifestyle regardless of what it does to your gut microbes.

This was a small study that still has to go through the peer-review process of being officially looke at by other scientists. But it has the potential to add to growing evidence that our lifestyle choices, including how much we move, can influence the microscopic world living inside us.

The cooking pot that became a symbol of Sweden’s commitment to helping Palestine

Source: The Conversation – UK – By Maria Småberg, Senior Lecturer, Peace and Conflict Research, Department of HIstory, Lund University

In the hills of the southern West Bank, a Swedish cooking pot has become a symbol of trust, resilience and forgotten solidarity. Half a century after it was first distributed as emergency aid, the cooking pots still gleam in the kitchens of Beit Awwa – reminding villagers of a time when Sweden stood by them in the aftermath of war.

Today, that legacy stands in stark contrast to Sweden’s current policy: a sharp reduction in aid to Palestine which has been folded into a regional government strategy for all of the Middle East and north Africa region.

The origins of these pots – and the trust they symbolise – were uncovered through research into the history of Swedish civil society organisations in Palestine. In the aftermath of the six-day war in 1967, Beit Awwa was one of several villages destroyed by Israeli forces. Villagers lost their homes, belongings and livelihoods.

Beit Awwa was not alone. In the chaotic aftermath of the six-day war, entire Palestinian villages were razed. Few international observers were present to document what happened. Israeli authorities actively tried to prevent outside scrutiny.

One of the few who bore witness was Sister Marie-Thérèse, a French nun from the Companions of Jesus order, who later wrote about the devastation in her diary. Israeli journalist Amos Kenan also reported on the forced expulsions, describing elderly people and mothers with infants wandering with white flags.

By mid-July 1967, John Reddaway, Unrwa’s deputy commissioner-general, estimated that around 16,000 people had been made homeless by the destruction of villages in the West Bank. Altogether, between 200,000 and 250,000 people from the West Bank went into exile.

Just a week after the war ended, on June 10, representatives from the Swedish organisation Individuell Människohjälp (IM), including the then ambassador, Bo Siegbahn, and consul, Arnold Hjertström, visited the ruins of Beit Awwa and the neighbouring village of Beit Marsam. They witnessed the devastation and appealed for help.

Sweden’s foreign ministry did not respond. But IM acted. With funding from the Norwegian Refugee Council and donations from the Swedish public (raising more than kr544,000 (£343,000) in July alone), IM chartered two planes from Malmö.

They delivered blankets, clothing, 100 tons of wheat flour, powdered milk, food supplies, primus stoves, and kitchen utensils — including the now-legendary Skultuna pots, a brand dating back to 1607.

The village elder, or mukhtar, oversaw the distribution, ensuring that aid was shared fairly. One of the men who proudly showed the pots to a visiting development worker decades later turned out to be the mukhtar’s grandson. IM also set up two tent camps and later sent medical supplies, prosthetics, spectacles and wheelchairs.

Cleaning up

Many years after the humanitarian intervention in 1967, Sweden returned to the Beit Awwa area to help resolve a new and complex problem. Swedish representatives were met with goodwill by the villagers, apparently based on the role Sweden had played decades earlier, even though no one was old enough to have their own clear memories of what had taken place in 1967.

During the 2010s, the Swedish consulate-general in Jerusalem identified a growing environmental crisis in the occupied Palestinian territory. In the villages near Hebron, many families had turned to informal recycling of Israeli electronic waste, a hazardous livelihood born out of economic necessity and political exclusion.

After the second intifada, when Palestinian workers were largely barred from entering Israel, some turned to old contacts among Israeli junk dealers. They began importing discarded electronics, burning them to extract copper and other metals, and selling the materials back through informal networks.

The environmental cost was devastating. Thick black smoke from burning cables choked the air and toxic runoff seeped into the soil and groundwater. The intricacies of the dangerous trade were brought to light by a group of researcher led by Yaakov Garb at Ben-Gurion University. They were able to link the burn sites to rising rates of lymphoma and other illnesses among children in the area.

In response to the crisis, researchers and villagers, supported by the Swedish International Development Cooperation Agency (Sida), developed a pilot project in 2015 to transform the informal recycling into a safer, small-scale industry.

The idea was to replace open-air burning with mechanical cable grinding, decontaminate the burn sites by removing toxic soil, and register the recycling operations as formal businesses with the Palestinian Authority. Local municipalities were also tasked with forming monitoring teams to prevent illegal burning.

The pilot project was a success. A significant area was cleaned, and a volunteer force of 60 people was quickly mobilised to enforce the new regulations. On both sides of the green line, the project earned praise – from Palestinian villagers, Israeli neighbours, and local authorities alike. In the villages, it became known as “the Swedish project”.

One cable-grinding machine remains in operation today – but like many well-intentioned initiatives in Palestine, the project eventually ran into political obstacles. Sustaining the success of the pilot project required a degree of formalised collaboration between Israeli and Palestinian authorities, but agreement on the details proved impossible and the structures of occupation left little room for long-term, trust-based governance.

Events since then, including the Israeli government’s declared intention to annex the West Bank and the trauma of October 7 2023 and its violent aftermath, have made any efforts at aid requiring collaboration between Israeli and Palestinian authorities virtually impossible.

Still, Sweden’s name continues to carry weight in Beit Awwa and beyond. The memory of those aluminium pots – still gleaming after half a century of use – speaks to a legacy of solidarity that transcends politics. As a historian and a development worker, we believe this legacy deserves to be remembered, and reconsidered, in light of today’s shifting aid policies.

Perhaps one day, that legacy will form the foundation for a renewed Swedish contribution to just peace and prosperity in the region.

Diane Keaton pioneered new kinds of complex femininity on screen

Source: The Conversation – UK – By Jen Harvie, Professor of Contemporary Theatre and Performance, Queen Mary University of London

American film actress Diane Keaton, who has died aged 79, was an icon of style but also character. She challenged the boundaries and range of what it was possible for women to play and be, especially in American cinema’s new wave of the 1970s and 80s.

Keaton was most famous for her performance as the title character in Woody Allen’s 1977 satirical romantic comedy-drama, Annie Hall. Her Annie could have been the love child of Katharine Hepburn and Charlie Chaplin.

She had Hepburn’s strength, intelligence, hair in a bun, and gender non-conforming trousers and tie; Chaplin’s comedy, goofiness and charm; and the idiosyncrasy of them both. Annie – like many more of Keaton’s characters – was kooky but smart, troubled and flawed, sweet but sensuous. And always endearing and complex.

Keaton won an Oscar for Annie. She physically overshadowed Allen despite being the same height (according to Allen), and her character’s awkward flirtatiousness, delight and curiosity balanced his character’s neurosis. Allen cast Keaton in eight of his movies and described her as, “with the exception of Judy Holliday”, “the finest screen comedienne we’ve ever seen”.

Keaton is better known as a comedian (or, as film critic Peter Bradshaw puts it, “a comic performer of ethereally self-aware genius”). But she had an impressive record in drama as well.

Keaton as Annie Hall.

Five years before Annie Hall, Keaton played the marrying-in outsider Kay to the mob family in Francis Ford Coppola’s The Godfather (1972). She appeared across the trilogy opposite Al Pacino.

Speaking to US broadcaster NPR in 2017, she explained that she drew on her experience as a young woman on The Godfather’s profoundly male-dominated set to understand Kay’s experience in the similarly male mob world.

The same year as Annie Hall, Keaton played Theresa Dunn in the much darker Looking for Mr Goodbar. Theresa leads a double life. By day she’s a Catholic teacher and by night, she cruises bars and discos for casual and sometimes rough sex.

Adapted from Judith Rossner’s 1975 novel, the film has been criticised for crude sensationalism, but Keaton’s portrayal of Theresa’s desire was broadly admired. Sight and Sound, for example, called her performance impressive “mainly because her strength and sensitivity as an actress seem to be operating apart from the underdeveloped character she is playing”.

Keaton also starred alongside Warren Beatty and Jack Nicholson in Reds (1981), Beatty’s epic drama exploring political and personal commitment in the context of journalists’ engagement with the Russian revolution. Keaton played activist Louise Bryant, who leaves her family to join the political struggle and, let’s be honest, handsome journalist Jack Reed (Beatty).

New York Times journalist Alissa Wilkinson wrote of the performance: “We might not all be Reed, the charismatic idealist giving speeches, but we might be Bryant, just trying to catch hold as history barrels past and discovering who we are inside of it.

Keaton’s later career

It is an indictment of Hollywood that, as Keaton aged, her roles and films generally became more conventional and less challenging than some of her earlier work. That said, she admitted that her own confidence affected her career, mistakenly believing that “without a great man writing and directing for me” she was “mediocre”.

Despite this, she did find and create roles that continued to challenge expectations about how women can behave, and she made a series of successful collaborations with director Nancy Meyers.

The trailer for Something’s Gotta Give.

In 1987’s Baby Boom, co-written by Meyers, Keaton played a career-committed businesswoman who inherits a baby that disrupts her life. Not only does she gradually cope, she eventually pulls off the hat-trick of growing her career, keeping the baby and snatching heartthrob Sam Shepard.

Keaton also starred in another tale of mainstream feminism triumphant, Meyers’ romantic comedy-drama Something’s Gotta Give (2003). Turning the tables on sexist stereotypes, Keaton’s successful playwright character “tames” playboy Nicholson while also attracting the much younger Keanu Reeves.

There is a sense that Hollywood couldn’t imagine Keaton’s early frisson in the body of an ageing woman. But she carried on doing what she could from within these more tame and often liberal feminist comedy-dramas, which sought gender equality but never questioned structures that were fundamentally sexist.

Keaton’s legacy persists. Some of the most influential American women television and filmmakers of the 21st century have sought to take up the mantle of her complex characterisations of smart, awkward and unconventional femininity, including Lena Dunham and Greta Gerwig. And we will always have Diane Keaton’s back catalogue to remind us of Hepburn and Chaplin’s strange, poignant, funny love child.
