New technologies usually follow the technology adoption life cycle. Innovators and early adopters rush to embrace new technologies, while laggards and skeptics jump in much later.

At first glance, it looks like artificial intelligence is following the same pattern, but a new crop of studies suggests that AI might follow a different course – one with significant implications for business, education and society.

This general phenomenon has often been described as “AI hesitancy” or “AI reluctance.” The typical adoption curve assumes a person who is hesitant or reluctant to embrace a technology will eventually do so anyway. This pattern has repeated over and over – why would AI be any different?

Emerging research on the reasons behind AI hesitancy, however, suggests there are different dynamics at play that might alter the traditional adoption cycle. For example, a recent study found that while some causes of this hesitation closely mirror those regarding previous technologies, others are unique to AI.

In many ways, as someone who closely watches the spread of AI, there may be a better analogy: veganism.

AI veganism

The idea of an AI vegan is someone who abstains from using AI, the same way a vegan is someone who abstains from eating products derived from animals. Generally, the reasons people choose veganism do not fade automatically over time. They might be reasons that can be addressed, but they’re not just about getting more comfortable eating animals and animal products. That’s why the analogy in the case of AI is appealing.

Unlike many other technologies, it’s important not to assume that skeptics and laggards will eventually become adopters. Many of those refusing to embrace AI actually fit the traditional archetype of an early adopter. The study on AI hesitation focused on college students who are often among the first demographics to adopt new technologies.

There is some historical precedent for this analogy. Under the hood, AI is just a set of algorithms. Algorithmic aversion is a well-known phenomenon where humans are biased against algorithmic decision-making – even if it is shown to be more effective. For example, people prefer dating advice from humans over advice from algorithms, even when the algorithms perform better.

But the analogy to veganism applies in other ways, providing insights into what to expect in the future. In fact, studies show that three of the main reasons people choose veganism each have a parallel in AI avoidance.

Ethical concerns

One motivation for veganism is concern over the ethical sourcing of animal by-products. Similarly, studies have found that when users are aware that many content creators did not knowingly opt into letting their work be used to train AI, they are more likely to avoid using AI.

These concerns were at the center of the Writers Guild of America and Screen Actors Guild-American Federation of Television and Radio Artists strikes in 2023, where the two unions argued for legal protections against companies using creatives’ works to train AI without consent or compensation. While some creators may be protected by such trade agreements, lots of models are instead trained on the work of amateur, independent or freelance creators without these systematic protections.

Environmental concerns

A second motivation for veganism is concern over the environmental impacts of intensive animal agriculture, from deforestation to methane production. Research has shown that the computing resources needed to support AI are growing exponentially, dramatically increasing demand for electricity and water, and that efficiency improvements are unlikely to lower the overall power usage due to a rebound effect, which is when efficiency gains spur new technologies that consume more energy.

One preliminary study found that increasing users’ awareness of the power demands of AI can affect how they use these systems. Another survey found that concern about water usage to cool AI systems was a factor in students’ refusal to use the technology at Cambridge University.

Personal wellness

A third motivation for veganism is concern for possible negative health effects of eating animals and animal products. A potential parallel concern could be at work in AI veganism.

A Microsoft Research study found that people who were more confident in using generative AI showed diminished critical thinking. The 2025 Cambridge University survey found some students avoiding AI out of concern that using it could make them lazy.

It is not hard to imagine that the possible negative mental health effects of using AI could drive some AI abstinence in the same way the possible negative physical health effects of an omnivorous diet may drive some to veganism.

How society reacts

Veganism has led to a dedicated industry catering to that diet. Some restaurants feature vegan entrees. Some manufacturers specialize in vegan foods. Could it be the case that some companies will try to use the absence of AI as a selling point for their products and services?

If so, it would be similar to how companies such as DuckDuckGo and the Mozilla Foundation provide alternative search engines and web browsers with enhanced privacy as their main feature.

There are few vegans compared to nonvegans in the U.S. Estimates range as high as 4% of the population. But the persistence of veganism has enabled a niche market to serve them. Time will tell if AI veganism takes hold.

When socialists win Democratic primaries: Will Zohran Mamdani be haunted by the Upton Sinclair effect?

Source: The Conversation – USA – By James N. Gregory, Professor of History, University of Washington

It has happened before: an upset victory by a Democratic Socialist in an important primary election after an extraordinary grassroots campaign.

In the summer of 1934, Upton Sinclair earned the kind of headlines that greeted Zohran Mamdani’s primary victory on June 24, 2025, in the New York City mayoral election.

Mamdani’s win surprised nearly everyone. Not just because he beat the heavily favored former governor Andrew Cuomo, but because he did so by a large margin. Because he did so with a unique coalition, and because his Muslim identity and membership in the Democratic Socialists of America should have, in conventional political thinking, made victory impossible.

This sounds familiar, at least to historians like me. Upton Sinclair, the famous author and a socialist for most of his life, ran for governor in California in 1934 and won the Democratic primary election with a radical plan that he called End Poverty in California, or EPIC.

The news traveled the globe and set off intense speculation about the future of California, where Sinclair was then expected to win the general election. His primary victory also generated theories about the future of the Democratic Party, where this turn toward radicalism might complicate the policies of the Democratic administration of Franklin D. Roosevelt.

What happened next may concern Mamdani supporters. Business and media elites mounted a campaign of fear that put Sinclair on the defensive. Meanwhile, conservative Democrats defected, and a third candidate split progressive votes.

In the November election, Sinclair lost decisively to incumbent Gov. Frank Merriam, who would have stood less chance against a conventional Democrat.

As a historian of American radicalism, I have written extensively about Sinclair’s EPIC movement, and I direct an online project that includes detailed accounts of the campaign and copies of campaign materials.

Upton’s 1934 campaign initiated the on-again, off-again influence of radicals in the Democratic Party and illustrates some of the potential dynamics of that relationship, which, almost 100 years later, may be relevant to Mamdani in the coming months.

California, 1934

Sinclair launched his gubernatorial campaign in late 1933, hoping to make a difference but not expecting to win. California remained mired in the Great Depression. The unemployment rate had been estimated at 29% when Roosevelt took office in March and had improved only slightly since then.

Sinclair’s Socialist Party had failed badly in the 1932 presidential election as Democrat Roosevelt swept to victory. Those poor results included California, where the Democratic Party had been an afterthought for more than three decades.

Sinclair decided that it was time to see what could be accomplished by radicals working within that party.

Reregistering as a Democrat, he dashed off a 64-page pamphlet with the futuristic title I, Governor of California and How I Ended Poverty. It detailed his plan to solve California’s massive unemployment crisis by having the state take over idle farms and factories and turn them into cooperatives dedicated to “production for use” instead of “production for profit.”

Sinclair soon found himself presiding over an explosively popular campaign, as thousands of volunteers across the state set up EPIC clubs – numbering more than 800 by election time – and sold the weekly EPIC News to raise campaign funds.

Mainstream Democrats waited too long to worry about Sinclair and then failed to unite behind an alternative candidate. But it would not have mattered. Sinclair celebrated a massive primary victory, gaining more votes than all of his opponents combined.

Newspapers around the world told the story.

“What is the matter with California?” The Boston Globe asked, according to author Greg Mitchell. “That is the farthest shift to the left ever made by voters of a major party in this country.”

Building fear

Primaries are one thing. But in 1934, the November general election turned in a different direction.

Terrified by Sinclair’s plan, business leaders mobilized to defeat EPIC, forming the kind of cross-party coalition that is rare in America except when radicals pose an electoral threat. Sinclair described the effort in a book he wrote shortly after the November election: “I, Candidate for Governor: And How I Got Licked.”

Nearly every major newspaper in the state, including the five Democratic-leaning Hearst papers, joined the effort to stop Sinclair. Meanwhile, a high-priced advertising agency set up bipartisan groups with names like California League Against Sinclairism and Democrats for Merriam, trumpeting the names of prominent Democrats who refused to support Sinclair.

Few people of any party were enthusiastic about Merriam, who had recently angered many Californians by sending the National Guard to break a Longshore strike in San Francisco, only to trigger a general strike that shut down the city.

The campaign against Sinclair attacked him with billboards, radio and newsreel programming, and relentless newspaper stories about his radical past and supposedly dangerous plans for California.

EPIC faced another challenge, candidate Raymond Haight, running on the Progressive Party label. Haight threatened to divide left-leaning voters.

Sinclair tried to defend himself, energetically denouncing what he called the “Lie Factory” and offering revised, more moderate versions of some elements of the EPIC plan. But the Red Scare campaign worked. Merriam easily outdistanced Sinclair, winning by a plurality in the three-way race.

New York, 2025

Will a Democratic Socialist running for mayor in New York face anything similar in the months ahead?

A movement to stop Mamdani is coming together, and some of what they are saying resonates with the 1934 campaign to stop Sinclair.

The Guardian newspaper has quoted “loquacious billionaire hedge funder Bill Ackman, who said he and others in the finance industry are ready to commit ‘hundreds of millions of dollars’ into an opposing campaign.”

In 1934, newspapers publicized threats by major companies, most famously Hollywood studios, to leave California in the event of a Sinclair victory. The Wall Street Journal, Fortune magazine and other media outlets have recently warned of similar threats.

And there may be something similar about the political dynamics.

Sinclair’s opponents could offer only a weak alternative candidate. Merriam had few friends and many critics.

In 2025, New York City Mayor Eric Adams, who abandoned the primary when he was running as a Democrat and is now running as an independent, is arguably weaker still, having been rescued by President Donald Trump from a corruption indictment that might have sent him to prison. If he is the best hope to stop Mamdani, the campaign strategy will likely parallel 1934. All attack ads – little effort to promote Adams.

But there is an important difference in the way the New York contest is setting up. Andrew Cuomo remains on the ballot as an independent, and his name could draw votes that might otherwise go to Adams.

Curtis Sliwa, the Republican candidate, will also be on the ballot. Whereas in 1934 two candidates divided progressive votes, in 2025 three candidates are going to divide the stop-Mamdani votes.

Religion also looms large in the campaign ahead. The New York City metro area’s U.S. Muslim population is said to be at least 600,000, compared to an estimated 1.6 million Jewish residents. Adams has announced that the threat of antisemitism will be the major theme of his campaign.

The stop-Sinclair campaign also relied on religion, focusing on his professed atheism and pulling quotations from books he had written denouncing organized religion. However, a statistical analysis of voting demographics suggests that this effort proved unimportant.

Unpacking Florida’s immigration trends − demographers take a closer look at the legal and undocumented population

Source: The Conversation – USA – By Matt Brooks, Assistant Professor of Sociology, Florida State University

Immigration has dominated recent public discourse about Florida, whether it be the opening of Alligator Alcatraz, a migrant detention facility in the middle of the Everglades, or Florida Gov. Ron DeSantis declaring an “immigration emergency” for the state that has lasted more than two years.

As demographers – that is, people who count people – we’ve noticed that this conversation has proceeded largely without the benefit of a clear description of Florida’s immigrant population.

Here’s a snapshot.

How many immigrants are in Florida?

We used data from the Office of Homeland Security Statistics and the American Community Survey, conducted annually by the U.S. Census Bureau. Homeland Security provides estimates of the state’s undocumented population and annual counts of authorized arrivals. Census data allow us to describe the social and economic characteristics of Florida’s immigrant population.

In 2023, the most recent year for which the Department of Homeland Security provides publicly available data, an estimated 590,000 immigrants without legal status were living in Florida. This is the third-largest population of immigrants without legal status in the U.S., behind California and Texas. But in contrast to those two states, the number of immigrants entering Florida illegally has been shrinking since 2018.

On the other hand, DHS data points to recent growth in Florida’s population of immigrants with legal status. This represents a rebound from declines between 2016 and 2020.

In 2023, Florida welcomed 72,850 residents from outside the country. This is just 0.3% of Florida’s population that year. About 95% of these new Florida residents were admitted as lawful permanent residents, or green card holders. The remainder entered as refugees (3%) and people granted asylum (2%).

For comparison, U.S. Census Bureau estimates suggest roughly 640,000 people moved to Florida in 2023 from other states.

Who makes up Florida’s immigrant population?

The American Community Survey data tells us even more about Florida’s immigrant population. The survey estimates that 4,996,874 foreign-born individuals lived in Florida in 2023, up from 3,798,062 in 2013. These numbers include those who are in the U.S. legally and illegally and encompass both recent arrivals and long-term residents.

In 2023, about 22% of Florida residents – and nearly 7% of Florida children – were immigrants. An additional 29% of Florida children have at least one immigrant parent.

According to the American Community Survey, nearly half of Florida’s immigrants were born in Cuba, Haiti, Venezuela, Colombia or Mexico. Despite being born elsewhere, Florida’s immigrants in many ways resemble other Floridians: About 20% hold a bachelor’s degree, compared to 22% of nonimmigrant Floridians, and 13% of both groups have a graduate degree. Nearly all Florida immigrants, 89%, speak English, and the majority, 57%, are naturalized citizens.

Immigrants make up a disproportionate share of Florida’s workforce, particularly in essential sectors of the state’s economy. They account for more than 47% of Florida’s agricultural workers, 41% of hotel workers and 35% of construction workers.

Florida immigrants also work in sectors that many might not consider to be “immigrant jobs.” They constitute 33% of child care workers, 21% of school and university employees and 27% of the health care workers.

Across all sectors, immigrants have lower unemployment rates than nonimmigrants. Although available data cannot tell us the extent to which these numbers are bolstered by undocumented immigrants, the importance of Florida’s immigrants for the state’s economy is undeniable.

Florida’s population is growing at a faster rate than any other state in the country, boosted by people moving in from abroad and from other states. This growth both reflects and feeds the state’s economic vitality. Between 2019 and 2024, Florida’s GDP grew twice as fast as the nation’s as a whole.

Is Florida experiencing an “immigration emergency”? That’s for politicians to decide. Our research suggests that policies that discourage new arrivals or encourage – or force – migrants to leave could jeopardize Florida’s robust economy and the well-being of its population.

Great Lakes offshore wind could power the region and beyond

Source: The Conversation – USA (2) – By Cora Sutherland, Interim Assistant Director, Center for Water Policy, University of Wisconsin-Milwaukee

Offshore wind power could provide far more electricity than the U.S. uses for residential, commercial and industrial purposes. But the federal government has recently stopped approving offshore projects in the ocean.

Another option is available, though: the Great Lakes, where we are based as water policy researchers, and where state agencies rather than federal officials are the trustees of the lakes. A January 2025 executive order from President Donald Trump attempts to stop all federal permits for offshore and onshore wind power pending a review of federal wind leasing and permitting practices.

But the states, not the federal government, handle leases and permits for wind power on the Great Lakes, though federal agencies are involved in the overall process. It is unclear how this executive order might impede federal action, but at the very least states could lay the groundwork now to be prepared to act when the next shift in federal priorities arrives.

A 2023 analysis from the National Renewable Energy Laboratory found that the Great Lakes states have enough offshore wind power potential to provide three times as much electricity as all eight Great Lakes states use currently, which would mean plenty left over to meet increasing demand or send power elsewhere in the country.

States are looking for opportunities

States have been forging their own paths separate from federal clean energy policy for decades. All eight Great Lakes states have state clean energy goals, and five of them – Illinois, Michigan, Minnesota, New York and Wisconsin – have a goal to achieve 100% clean or renewable energy by 2040 or 2050.

The challenge is not just to transform the current energy supply. As transportation and other sectors electrify, that increases electricity demand. As artificial intelligence proliferates, tech companies need more and more electricity and water for their data centers. By 2028, data centers are projected to consume nearly 12% of the country’s total usage, which requires massive increases in production in the Great Lakes and other key locations.

Companies and states are looking high and low to find enough electricity to meet the rising demand. They are extending the lives of coal-fired power plants and building new gas-fired power plants. Elon Musk’s xAI company has even been powering an artificial intelligence data center in Tennessee with massive generators that add air pollution without permits.

Government and industry are also looking to other sources, such as investing in nuclear fusion advancement and building geothermal plants.

A brief history

In the 2000s and 2010s, the Great Lakes Commission Wind Collaborative, Wisconsin Public Service Commission and the Michigan Great Lakes Wind Council began to sketch out regulations for offshore wind in the Great Lakes and to identify locations that might be suitable for the turbines.

In 2012, the Obama administration agreed to collaborate with five Great Lakes states – Illinois, Michigan, Minnesota, New York and Pennsylvania – to streamline a permitting process for offshore wind development. Multiple projects were proposed off the shores of Michigan, Ohio and Ontario, Canada, though Ontario banned offshore wind projects in 2011.

Since then, momentum has stalled. One effort, the Icebreaker project off Cleveland, was approved and survived various legal challenges, but the project backers paused it indefinitely in 2023 due to the economic impacts of the legal delays.

Community activists are split, with some embracing offshore wind in the Great Lakes as part of a clean energy future and others vocally opposing it, citing environmental, health and economic concerns.

As of mid-2025, the Great Lakes were home to no offshore wind turbines.

A map shows relatively high wind speeds across much of the Great Lakes.
Wind speeds at the altitude of 460 feet (140 meters) above the surface of the Great Lakes are high enough to drive turbines that generate wind power.

Big potential, big unknowns

States continue to explore the possibility of offshore wind power in the Great Lakes. In early 2025, Illinois legislators again introduced a bill to create a pilot wind project off Chicago in Lake Michigan.

Also in 2025, Pennsylvania legislators introduced a bill to facilitate offshore wind power in Lake Erie. If adopted, the law would map which areas are fit to be leased for development by avoiding nearshore areas, shipping lanes and migration pathways. The Ontario Clean Air Alliance is pushing the province to lift its moratorium and reconsider offshore wind in Canadian waters.

A lot of details remain unknown. New York state supports offshore wind in the ocean but says “Great Lakes Wind does not provide the same electric and reliability benefits” by comparison. Ocean wind tends to be closer to areas where electricity demand is high, which can make those projects more cost-effective.

New York also concluded in 2022 that despite the combined 144.5 terawatt-hours of annual technical potential in state waters in Lake Erie and Lake Ontario, “numerous practical considerations … would need to be addressed before such projects can be successfully commercialized.”

To further explore the concerns New York’s report and others have raised, in 2024, with National Science Foundation funding, we collaborated with a team of researchers looking at a wide range of issues, including engineering, environmental effects and law. That effort resulted in articulating research questions whose answers would clarify how realistic different aspects of offshore wind could be in the Great Lakes, such as:

State jurisdiction is an opportunity

In the oceans, U.S. states have jurisdiction from shore out three miles, with the federal government’s jurisdiction continuing out for hundreds of miles beyond that. So offshore project sites in the oceans are leased by the federal government.

The Great Lakes are different. The state governments hold the lakes’ waters and submerged lands in trust for the public. And state jurisdiction extends from shore all the way out to the boundary of a neighboring state’s jurisdiction or the international boundary with Canada.

Regulation of planning, site selection, leasing and other elements of offshore wind projects in the Great Lakes are the responsibility of one or another U.S. state. The federal government’s role is secondary, conducting environmental reviews and protecting navigation, but could still result in slowing state-led projects.

In research we published in 2024 and 2025, we explain that states could evaluate and select offshore wind projects based on a range of social and environmental benefits, in addition to financial considerations. For instance, they could look for designs that provide fish habitat or seek corporate partners that agree to train local workers, manufacture turbines and ships near the lakes, and provide cheaper electricity to local consumers.

Despite all the unknowns, we encourage greater support for research to harness the potential of offshore wind energy in the Great Lakes to be a renewable resource for states, the region and the nation as a whole.

Parents don’t need to try harder – to ease parenting stress, forget self-reliance and look for ways to share the care

Source: The Conversation – USA (2) – By Elizabeth Sharda, Associate Professor of Social Work, Hope College

Modern parents experience many demands, with little support. Abraham Gonzalez Fernandez/Moment via Getty Images

I wrap up my workday and head for home, making a quick stop to grab the supplies my sixth grader needs for a project due this week and some ingredients for a quick dinner.

Once home, I check the sixth grader’s school website and discover a missing assignment. Bringing this up sparks a minor meltdown. I summon the emotional energy to help her calm down and problem-solve. My husband arrives home with our high schooler, who’s discouraged by something that happened at soccer practice. We’ll have to process that later.

Around the dinner table, we realize that both kids have sports practices Thursday, on opposite ends of town, at the same time as a mandatory parent meeting at school. And now I’m ready for my own meltdown.

On this particular evening, my family wasn’t navigating anything unique or especially catastrophic. Scenes like this play out nightly in homes across the United States. In fact, my family’s circumstances offer the protections of multiple forms of privilege. Certainly others have more difficult circumstances.

Why is it still so hard?

For a long time, I felt ashamed for being overwhelmed by parenthood. How do others seem to have it all together? Of course, the highlight reel of social media only fueled this comparison game. I often felt that I was falling short, missing some hack that others had found for not feeling constantly exhausted.

The reality is I’m far from alone in experiencing what social scientists term parenting stress. Defined as the negative psychological reaction to a mismatch between the demands of parenting and the resources available, parenting stress has become increasingly prevalent over the past five decades. In the wake of the COVID-19 pandemic, nearly half of all parents in the U.S. said their stress was completely overwhelming on most days.

Stress like this has an impact: Parents who experience high levels of parenting stress have decreased mental health and feel less close with their children.

I began researching parental stress and well-being when, several years after becoming a parent, I left my job as a social worker and entered a Ph.D. program. Through this process, I learned something that changed my perspective entirely: Parents today experience such high levels of stress because people have never traditionally raised children in isolation. And yet, we are more isolated than ever.

It clicked: Parents don’t need to do more or try harder. We need connection. We don’t need more social media posts on the “top three ways to keep your family organized.” We need a paradigm shift.

The myth of family self-reliance

Throughout human history, people primarily lived in multigenerational, multifamily arrangements. Out of necessity, our hunter-gatherer ancestors relied upon their clan-mates to help meet the needs of their families, including child-rearing. Research over time and across cultures suggests that parents are psychologically primed to raise children in community – not in isolated nuclear family units.

Anthropologists use the term alloparents – derived from the Greek “allo,” meaning “other” – to describe nonparent adults who provide care alongside that provided by parents.

Research suggests that alloparenting contributes to child well-being and even child survival in populations with high rates of child mortality. A 2021 study of a present-day foraging population in the Philippines found that alloparents provided an astounding three-quarters of the care for infants and an even greater proportion of the care for children ages 2 to 6.

In contrast, the ideal of the nuclear family is incredibly recent. It developed with industrialization, peaking in the 1950s and 1960s. Despite the significant changes in family structure – such as an increase in single-parent households – since that period, the paragon of the self-reliant nuclear family persists.

And yet, support from others is a key factor in family resilience. The familiar adage “It takes a village to raise a child” is, in fact, bolstered by social support research among parents in general, as well as those of children with special needs.

Parenting with collective care

Social support, while often viewed as a singular phenomenon, is actually a constellation of actions, each with its own unique function. Social scientists specify at least three types of support:

  • Tangible: Material or financial resources or assistance
  • Emotional: Expressions of care, empathy and love
  • Informational: Provision of information, advice or guidance

Different parenting challenges call for different types of support. When my husband and I realized we had three commitments in a single evening, we didn’t need advice on managing our family’s calendar; we needed someone to take our kid to practice – that’s tangible support. When my tween was blowing up over homework, I didn’t need someone to bring us dinner; I needed to remember what I learned from a book on parenting adolescent girls – that’s informational support.

To move away from the myth of family self-reliance and back toward an ideal of collective care would take a paradigm shift, requiring intervention at every level, from federal to state to family. A 2024 Surgeon General’s Advisory on parenting stress called it an urgent public health issue and provided recommendations for government leaders, service systems and communities. Systemic strategies like providing access to high-quality mental health care, expanding programs like Head Start that support parents and caregivers, and investing in social infrastructure like public libraries and parks could all help reduce parenting stress in the U.S.

Personal steps toward a paradigm shift

Parenting stress is not a problem that can be solved solely by the individuals experiencing it. But here are five ways you can start making the shift toward collective care in your own life:

  1. Take stock of your network. Assess not only in terms of the number of supporters, but what types of support they offer. Do you have plenty of people to talk to, but no one who would bring you a meal or give your kid a ride? Identify gaps and consider ways to round out your “village.”
  2. Start small. Introduce yourself to your retired neighbor. Sit next to another parent at your kid’s sporting event. Talk to the babysitter you regularly see at the playground. Supportive relationships don’t just happen; they are grown.
  3. Offer help to others. While it seems counterintuitive, people who give support to others experience greater well-being and even longevity compared with those who don’t. Helping others also creates the opportunity for reciprocity. Those you support may be more likely to return the favor in the future.
  4. Normalize asking for help and taking it when offered. For many people, asking for support is hard. It requires dropping the facade and letting people in on your struggles. However, people are often more willing to help than you might assume. Further, allowing others to help you gives them permission to voice their own needs in the future.
  5. Consider your caregiving expectations. The way others care for your children may not mirror your way entirely. Consider what are nonnegotiable practices for your family – such as limits on screen time – and what is worth loosening up on – like veggies at every meal – if it means you have more alloparents helping you out.

None of these suggestions are easy. They take time, vulnerability and courage. In our society of rugged individualism and nuclear family self-reliance, parenting through a lens of collective care is downright countercultural. But perhaps it’s closer to how we, as humans, have raised children throughout the millennia.

In a story in the Buddhist canon, a grief-stricken mother named Kisa Gautami loses her only child and carries the body around town, searching for some way to resurrect the child.

When she encounters the Buddha, he asks her to collect several mustard seeds from a family that has never experienced death. Not surprisingly, Kisa Gautami is unable to find a single such family. She buries her child and decides to cultivate a spiritual life.

I thought of Kisa Gautami’s story when I first encountered the 2020 Korean documentary “Meeting You,” in which virtual reality technology is used to reunite a grieving mother, Jang Ji-sung, with her deceased 7-year-old daughter, Nayeon. While the virtual reunion was moving to witness, I wondered whether it was truly helping the mother to heal, or whether it was deepening an avoidance of grief and of the truth.

Since the documentary first aired, the business of digitally resurrecting the deceased has grown significantly. People are now using AI to create “grief bots,” which are simulations of deceased loved ones that the living can converse with. There has even been a case where an AI-rendered video of a deceased victim has appeared to deliver a court statement asking for the maximum sentence for the person who took their life.

As a Buddhist studies scholar who has experienced several bereavements this year, I have turned to Buddhist teachings to reflect on how creating a digital afterlife for loved ones may inadvertently enhance our suffering, and what alternative ways of grieving Buddhism might offer.

Buddhism’s view on suffering

According to Buddhist thought, the root of all suffering is clinging to illusions. This clinging creates karma that perpetuates negative cycles – for oneself and others – which endure lifetimes. In Mahayana Buddhism, the path to liberate oneself from this suffering begins by becoming a bodhisattva, someone who devotes their life to the liberation of self and others. Mahayana Buddhism, which introduced the idea of celestial bodhisattvas, is the most widely practiced form of Buddhism, particularly in East Asia and the Tibetan Himalayan regions.

In the “37 Practices of All the Bodhisattvas,” the 14th-century author Gyelse Tokme Zangpo wrote:

The practice of all the bodhisattvas is to let go of grasping
When encountering things one finds pleasant or attractive,
Consider them to be like rainbows in the summer skies –
Beautiful in appearance, yet in truth, devoid of any substance.

A digital avatar of the deceased may provide temporary comfort, but it may distort reality in an unhealthy way and intensify our attachment to an illusion. Interactions with a griefbot that responds to our every request may also diminish our memories of the deceased by creating an inauthentic version of who they were.

Grief as a catalyst for compassion

In the tradition of Buddhism that I specialize in, called the Great Perfection – a tradition of Vajrayana Buddhism, which is a branch of Mahayana – uncomfortable feelings such as grief are considered precious opportunities to cultivate spiritual insight.

In a text called Self-liberating Meditation, a 19th century mendicant teacher of the Great Perfection known as Patrul Rinpoche wrote: “No matter what kind of thoughts arise – be they good or bad, positive or negative, happy or sad – don’t indulge them or reject them, but settle, without altering, in the very mind that thinks.”

The Great Perfection contends that all of our emotions are like temporary clouds, and that our true nature is awareness, like the blue sky behind the clouds. Grief and other challenging emotions should not be altered or suppressed but allowed to transform in their own time.

In a culture where we are taught that negative emotions should be eliminated or pushed aside, not pushing away grief becomes a practice of great kindness toward oneself. By cultivating this awareness of our emotions, grief becomes a catalyst for compassion toward others. In Buddhism, compassion is the seed of awakening to the truth of interdependence – the fact that none of us exist as discreet beings but are deeply interconnected with all other beings and life forms.

Communal rituals

Compassion manifests outwardly in community rituals that process grief, such as the 49-day Buddhist service, common to the Great Perfection and other Buddhist traditions.

Many Buddhists believe that it takes 49 days for the consciousness of the deceased to transition into their next life. During this time, the family sets up a special altar and recites prayers for the deceased, often with the support of ordained monks and nuns. Practicing generosity toward others is also recommended to accumulate merit for the deceased.

These communal rituals provide much-needed outlets, time and support for processing grief and having it witnessed by others. The time and attention given to the grief process sharply contrasts to the situation in the United States, where bereavement leave is often limited to three to five days.

Deepening relationship with impermanence

In opting for digital avatars, we may undermine what Buddhism would consider to be critical moments for genuine transformation and connection.

When I think of the family and friends who have passed away this year, I empathize with the desire to hear their voices again, or to have conversations that provide closure where there was none. Rather than turning to a technological fix that promises a reunion with the deceased, I choose to deepen my relationship with impermanence and to savor the fleeting moments that I have with those I love now.

As Kisa Gautami’s story shows, the desire to bring back the dead is not new, but there is great benefit in allowing grief to run its course, including a felt sense of compassion for oneself and all others who have ever experienced similar forms of grief.

Iranian Canadians watch the Israel-U.S. attacks on Iran from afar

Source: The Conversation – Canada – By Fateme Ejaredar, PhD candidate in Sociology, University of Calgary

Iranian Canadians have been following the news in Iran carefully. Sadaf Vakilzadeh/Unsplash, CC BY

The recent war waged by Israel and the United States on Iran killed at least 935 people and wounded another 5,332. There’s currently a ceasefire, but the conflict shocked the world and has had unique impacts on Iranians in the diaspora.

Many Iranians in Canada were glued to their media feeds to stay close to Iran and their friends and families.

Based on preliminary interviews with 30 Iranian activists in Canada, many in the diaspora have experienced what they call “survivor’s guilt.”

The interviews are part of a PhD study conducted online or in person by one of the authors of this story, Fateme Ejaredar, and supervised by co-author Pallavi Banerjee. The information from these interviews helps to untangle the roots of political tensions and evolving solidarities in the Iranian diaspora in Canada. For this research, 30 interviews were conducted, with seven followups after the conflict began on June 13, 2025.

A large share of the Iranian diaspora in Canada is comprised of activists who disavow the Islamic Republic. According to The New York Times, the Iranian diaspora includes “exiled leftists, nationalists, secular democrats, former prisoners, journalists, human rights advocates and artists.” This population of diasporic Iranians has been supporting progressive change in Iran.

There are also those who oppose the Islamic Republic in support of the deposed shah, a movement currently swayed by Reza Pahlavi, the son of Iran’s last shah. They see the U.S. and Israel as liberators of the Iranian people. The current war resurfaced many of these tensions that continue to divide the diaspora.

The war has left Iranian activists in the diaspora contending with contradictions about both their standing as activists while mourning the assaults on their country, both from within and outside.

Living in between homeland and hostland

Canada has the second largest Iranian diaspora in the world. Iran’s tumultuous political climate has kept the diaspora on edge and divided since the 1979 revolution that deposed the shahs.

After the revolution, many left-wing and other opposition activists who resisted both the pre- and post-revolutionary regimes went into exile. Continued political repression and economic hardship later forced even more Iranians, including activists, to leave the country. Strife peaked again in 2022 during the “Woman, Life, Freedom” protests which deeply impacted the diaspora.

Matin, a participant in her 30s from Alberta (all names of interviewees are pseudonyms), said:

“I’m sad that my home is being bombed. And you don’t have the energy to argue in this situation. For a soul that’s already tired, its wounds from 2022 aren’t healed yet, it can’t go into this again. It’s a dead end.”

Sociological research on migration and transnationalism has explained how those exiled from their homelands and living in diaspora reside in the “in-between lands.”

This is heightened when the homeland is in a state of political disarray, producing what sociologists have called “exogenous shocks” for the diaspora.

This is the unsettled feeling Iranians in the diaspora have been contending with for the last 45 years. They are constantly navigating life in between the homeland and hostland.

Fragmented nationalism

People’s fragmented sense of nationalism can shape responses to upheavals in the homeland.

Many we spoke with struggle with their own interpretations of Iranian nationalism that clash with their disdain for the Islamic Republic. Their disdain is rooted in their own lived experiences under the regime — ranging from the loss of basic rights and freedoms, to harsh repression including imprisonment and torture for some, or simply an unfulfilled desire of living in a peaceful and free society.

Vida, an interviewee in her 30s who lives in Saskatchewan, said even though she despised the politics of the Islamic Republic and in the past had celebrated the death of key officials like Qasem Soleimani, the recent war has invoked some conflicting feelings about the death of military leaders.

She took pride in solidarities forged among the diaspora due to the war and interpreted it as nationalism. Vida said:

“I never was a nationalist, and I hate nationalism. But there were moments these days that I felt proud. Seeing all the solidarity between people, seeing how they helped each other…”

Even as the activists feel protective of their country because of the war, they also experience a deep sense of loss and guilt they have always felt in exile.

Tensions in the diaspora

Iran’s relationship with the West has continued to be fraught.

The West, particularly the U.S., has leveraged Iran’s repression of women to economically disable Iran through sanctions, breaking down possibilities of diplomacy between Iran and the U.S. But feminist scholars have argued this stance has only further empowered the authoritarian and patriarchal political forces in Iran..

Iranian activists in the diaspora contend with both resisting the Islamic Republic’s role in oppression of Iranians in Iran and the American role in marginalizing Iranians in Iran.

The ‘Iran of our dreams’

The in-between spaces are precarious and unpredictable. But they also bring new possibilities and in this case, as many interviewees have indicated, acts of resistance from afar.

This can be further activated in moments of upheaval. And those living in the in-between spaces can often form new alliances and solidarities.

For many activist Iranians, the resistance in Palestine has been a source of inspiration since before the revolution of 1979. Many participants in this study mentioned in their interviews how they have long felt solidarity with Palestinians, but they say since June 13, they have an even deeper understanding of their situation.

Zara, in her 40s from Ontario, said she now understands more deeply how the world could be indifferent towards those critiquing the actions of Israel, saying she feels:

“… a sense of helplessness and desperation against all that illogical violent power.”

Despite the desolation expressed by our interviewees about the war, many activists also expressed faith in resistance for freedom and justice that allows them to envision a different future.

Jamshid, in his 60s in British Columbia, shared his future vision of Iran. It is:

“ … an Iran that lives in peace. There is social justice in it and no one is injured. It takes care of itself. It’s very kind, immensely kind… Maybe one day it will happen and we’re not here to see it.”

De recibir descargas eléctricas a triturar gusanos: por qué el aburrimiento nos vuelve impredecibles

Source: The Conversation – (in Spanish) – By Sergio Pirla, Profesor Ayudante Doctor, Dept. Organización de Empresas, Universidad de Zaragoza

El filósofo danés Kierkegaard decía que el aburrimiento es el origen del mal. ¿Exageraba o tenía razón? A continuación explicaremos cómo un estado emocional que solemos ignorar podría estar detrás de muchas de nuestras decisiones más cuestionables.

El aburrimiento es un estado emocional desagradable que surge cuando nos enfrentamos a situaciones poco estimulantes. Se caracteriza por una sensación de inquietud, falta de interés y dificultad para mantener la atención en la tarea actual.

Suele ir acompañado de una notable búsqueda de estímulos externos y un aumento en la impulsividad. Es precisamente esta búsqueda impulsiva de estimulación la que puede empujarnos a tomar malas decisiones.

Un claro ejemplo aparece en un experimento publicado en la revista Science. Los investigadores pidieron a un grupo de voluntarios que pasaran 15 minutos en una sala sin nada que hacer más que “entretenerse con sus propios pensamientos”. Durante ese tiempo, los participantes tuvieron la opción de autoadministrarse una descarga eléctrica que previamente habían probado y calificado como desagradable.

De hecho, los voluntarios afirmaron que estarían dispuestos a pagar por evitar recibir otra descarga. Sin embargo, durante los 15 minutos sin poder hacer otra cosa, el 67 % de los hombres y el 25 % de las mujeres se administraron al menos un shock eléctrico (con un participante llegando a la sorprendente cifra de 190 descargas eléctricas en los 15 minutos del estudio).

La escapada a través de los riesgos

En el experimento, la descarga eléctrica funcionaba como una forma de estimulación ante el aburrimiento. En la vida cotidiana, también buscamos maneras de escapar de esta emoción, y una de ellas –quizás la más poderosa– es asumir riesgos.

La mayoría de los riesgos conllevan un componente estimulante. Por eso no sorprende que quienes tienen una mayor propensión a aburrirse muestren una tendencia más elevada a conducir de forma temeraria, participar en conductas sexuales de riesgo o consumir alcohol: todos ellos comportamientos con un evidente potencial dañino.

Esta relación entre aburrimiento y conductas de riesgo resulta especialmente pronunciada entre quienes más tienden a aburrirse: los hombres jóvenes.

Los comportamientos temerarios como respuesta al aburrimiento también son frecuentes en uno de los contextos donde más se experimenta esta emoción: el trabajo. Por ejemplo, varios estudios demuestran que quienes se aburren con mayor frecuencia en el entorno laboral son también más propensos a distraerse, fingir que están ocupados e incluso a sustraer equipamiento o materiales de la empresa.

Aburrimiento y rasgos sádicos

Pero la toma de riesgos no es la única manera de escapar del aburrimiento. Otra vía –igual de poderosa– es buscar estimulación en nuestro entorno social. En algunos casos, esta búsqueda puede traducirse en algo positivo, como cuando encontramos dicha estimulación en la ayuda a los demás.

En otros casos, la búsqueda toma un tinte oscuro. La evidencia científica demuestra que el aburrimiento es especialmente pernicioso cuando se da en ciertos individuos, particularmente aquellos que presentan rasgos sádicos.

Las personas con estos rasgos tienden a disfrutar al causar daño o malestar a los demás, y encuentran divertido o estimulante comportarse de esa forma. Por eso, el aburrimiento en este tipo de individuos se ha relacionado con una variedad de conductas indeseables, que van desde insultar o amenazar en redes sociales, hasta el acoso escolar (bullying) o incluso el maltrato físico en contextos como el cuidado de los hijos.

La evidencia más llamativa fue recogida por el psicólogo alemán Stefan Pfattheicher y sus colaboradores. En este experimento, los investigadores mostraron a un grupo de participantes un vídeo de una cascada durante 20 minutos para inducir aburrimiento. A otro grupo le pusieron un documental sobre los Alpes (de similar duración) pensado para mantener su interés.

Durante los vídeos, los participantes estaban sentados de forma individual frente a una mesa en la que había tres vasos con gusanos vivos y una trituradora de café modificada. Aunque la trituradora había sido alterada para que los animales no sufrieran ningún daño, los participantes fueron informados de que podían usar la máquina para triturar los gusanos si así lo deseaban.

Al termino de los vídeos, solo 1 de los 62 participantes que vio el documental sobre los Alpes intentó triturar un gusano (un 1,6 %). De entre quienes vieron el vídeo de la cascada, 12 de 67 intentaron triturar al menos un gusano (un 17,9 %).

Experimentos con incentivos monetarios

¿Siempre tomamos peores decisiones si estamos aburridos? No necesariamente. Hay situaciones en las que el tedio no nos empuja necesariamente a asumir riesgos ni a comportarnos de manera antisocial.

Por ejemplo, un estudio con 1 300 participantes no encontró que el aburrimiento influyera en la decisión de invertir pequeñas sumas de dinero entre opciones seguras o arriesgadas. De manera similar, otro trabajo con más de 3 500 personas no halló efectos del hastío sobre la generosidad: los participantes no fueron más propensos a donar dinero a otros ni a reducir el pago que estos recibirían por participar en el estudio.

Estos dos últimos estudios comparten ciertas características que los distinguen de los anteriormente citados. Se trata de experimentos con incentivos monetarios reales, en los que la tarea principal consiste en distribuir una pequeña suma de dinero. Es decir, se basan en decisiones que carecen de un valor estimulante importante.

Y es que, si la decisión es ya de por sí aburrida, aburrirnos no nos hace decidir mal.

¿Tomamos las decisiones de forma libre?

Source: The Conversation – (in Spanish) – By Diego Emilia Redolar Ripoll, Associate professor, UOC – Universitat Oberta de Catalunya

Si antes de tomar una decisión dedicamos un rato a pensar racionalmente, eso implica integrar y evaluar múltiples factores, unos externos a la persona y otros de naturaleza interna. Una de las primeras cosas que hacemos en estos casos es sopesar, es decir, comparar el valor de las diferentes opciones entre las que tenemos que elegir. Y a partir de ahí generamos una regla que nos permita seleccionar la alternativa más valiosa en nuestro caso.

Ciertas áreas de la corteza prefrontal, como la región dorsolateral y la corteza cingulada anterior, son críticas para escoger porque permiten sopesar el valor a largo plazo de cada opción en las decisiones que tomamos.

Imaginemos que nos piden que elijamos para desayunar entre un pastel de chocolate o un yogur con fruta. Sabemos que el lácteo es la alternativa más saludable, pero puede que el pastel nos atraiga más, dado que su sabor es más gratificante. ¿Gana lo sano o lo sabroso? En 2009, un estudio reveló que la actividad de la corteza prefrontal ventromedial estaba correlacionada con la preferencia por el gusto del alimento, sin importar si era saludable o no. Por el contrario, la actividad de la corteza prefrontal dorsolateral se disparaba cuando el sujeto descartaba un alimento que le resultaba especialmente apetecible, pero que, lamentablemente, no era sano.

Con los resultados de este estudio, podríamos afirmar que la región ventromedial es capaz de analizar el valor de las opciones a corto plazo, mientras que la zona dorsolateral nos ayudaría a incorporar en nuestra decisión consideraciones del valor a largo plazo de las dos opciones. En cierto modo, ambas actúan como si fueran un demonio y un ángel, hablándonos en uno y otro oído durante la toma de decisiones.

¿Y de qué depende que gane el ángel o el demonio? La neurociencia nos dice que hay diversos factores que pueden mover la balanza hacia un lado o el otro: desde las diferencias individuales (lo que tradicionalmente llamamos “fuerza de voluntad” de cada uno), hasta la magnitud del premio (no es lo mismo un pastel de chocolate que un viaje a Islandia, donde sopesamos el gasto que nos supone frente a lo bien que nos lo vamos a pasar), pasando por el estado físico (si estamos más cansados o con más sueño) o emocional (si nos sentimos más tristes o más alegres).

Damos prioridad a lo familiar

Las personas no siempre tomamos las decisiones basándonos en una evaluación racional que sopesa sus costes y beneficios a corto o largo plazo. Muchas se adoptan siguiendo reglas que nos permiten simplificar las situaciones más complejas o difíciles. A falta de más información, solemos decantarnos por la opción más familiar.

Esto nos permite tomar una decisión de una forma más rápida y sencilla, dado que lo familiar se relaciona con la popularidad y otras características positivas. En este sentido, se huye de la ambigüedad y de las situaciones en las que desconocemos las probabilidades de los posibles resultados.

Por ejemplo, imagine que lo único que conocemos del polo es que se trata de un deporte donde dos equipos con cuatro jugadores cada uno, montados a caballo, intentan llevar una pequeña pelota hacia la portería del rival. Resulta que acudimos a un experimento en la universidad y nos piden que apostemos una cantidad nada despreciable de dinero por uno de los equipos que se enfrenta en un partido de polo. ¿Cómo escogemos?

En situaciones de ambigüedad como esta, en la que debemos tomar una decisión casi sin datos, se activan la corteza orbitofrontal (porción que queda por encima de los ojos) y regiones laterales de la corteza prefrontal. La primera se enciende, seguramente, debido a que vivimos la situación como algo aversivo, que no nos gusta y nos desconcierta. En el caso de las regiones laterales de la corteza prefrontal, su activación refleja la necesidad de plantearnos las probabilidades para construir una regla de decisión: no se tiene información, pero, aun así, se buscan posibles indicios sobre los que sustentar la elección.

Pulsar botones del cerebro para entender la generación de ideas

Existen técnicas que, de forma no invasiva, nos permiten activar o inactivar regiones corticales durante unos minutos para hacer pruebas cognitivas y analizar cómo afecta el aumento o la disminución de la excitabilidad de las neuronas de esas regiones. Son las denominadas “técnicas de estimulación cerebral no invasiva”.

Imaginemos que tenemos la hipótesis de que determinada región de la corteza cerebral es crítica para el cálculo aritmético. La podemos inhibir con este tipo de técnicas y, a continuación, hacer pruebas en las que el participante tenga que demostrar sus habilidades de cálculo. Si la región es cardinal para esa función, el voluntario lo hará peor que cuando realice estas tareas sin estimulación (de hecho, este experimento lo llevamos a cabo en nuestro laboratorio, pero ahora esta historia no viene al caso).

Pues bien, la investigación sobre estimulación cerebral no invasiva ha empezado a examinar de forma empírica los efectos del razonamiento sobre la creatividad, algo importante en la toma de decisiones. En este sentido, algunos estudios han demostrado que la inhibición de diferentes regiones laterales de la corteza prefrontal disminuye los mecanismos de control cognitivo, lo que facilita la generación de ideas creativas. Es decir, si se inhibe el funcionamiento de determinadas regiones cerebrales, podemos aumentar la creatividad de esas personas.

En 2021, un equipo de investigadores llevó a cabo un estudio en el que incrementaban la excitabilidad de las neuronas de la corteza prefrontal con el objetivo de analizar cómo afectaba a la generación de ideas novedosas en función de las demandas de la tarea. Los participantes tenían que leer frases a las que les faltaba la última palabra, y se les pedía que la completaran con un final poco común pero apropiado. Se observó que cuando se activaba la corteza prefrontal, aumentaba la adecuación y disminuía la novedad (y, por lo tanto, la creatividad) de las respuestas de los participantes.

Ese mismo año, llevamos a cabo un experimento en nuestro laboratorio para analizar cómo la inhibición de determinadas regiones de la corteza prefrontal modificaba la toma de decisiones de riesgo. Propusimos a los participantes que hinchasen un globo. Cada vez que soplaban iban ganando dinero que después se llevarían a casa. No obstante, cada globo estaba programado de forma aleatoria para explotar con un determinado número de insuflaciones.

Así vimos que inhibir zonas dorsolaterales de la corteza prefrontal hacía que los participantes se arriesgaran más, pero los resultados parecían depender de su personalidad. Es decir, no todos nos comportamos igual cuando tomamos decisiones en circunstancias de riesgo. En parte, esto se explica por el funcionamiento de regiones implicadas en el control cognitivo (que incluye todas las funciones ejecutivas superiores, incluido el razonamiento), pero también por la personalidad de cada uno.

La razón sin emoción es como un general sin ejército

Por último, las emociones también pueden influir en las decisiones que tomamos, cómo esbozamos el futuro o a qué prestamos atención y, después, recordamos. ¿Qué pinta, entonces, la razón? Emoción y razón han de ir de la mano, deben estar en equilibrio. La razón puede ayudar a generar nuevas respuestas emocionales que sean capaces de sustituir los sentimientos que ya tenemos, potenciándolos o añadiendo argumentos que los modifiquen y adapten a la situación que vivimos o al contexto social y normativo en el que nos encontramos. En los pacientes que presentan lesiones en regiones cerebrales críticas para las emociones, los procesos racionales se ven menoscabados a medida que el procesamiento de la información emocional no es correcto.

En palabras de Ignacio Morgado, “la razón sin emoción es como un general sin ejército; la emoción sin razón es como un coche sin frenos”.

El sufrimiento mudo e invisible de los peces

Source: The Conversation – (in Spanish) – By Rubén Bermejo Poza, Profesor Ayudante Doctor en el Departamento de Producción Animal UCM, Universidad Complutense de Madrid

Cada año, más de mil millones de peces son capturados o criados en Europa para el consumo humano. Son parte esencial de la alimentación, de las mesas, supermercados y recetas tradicionales. Sin embargo, a diferencia de otros animales de granja como las vacas, cerdos o gallinas, su bienestar sigue siendo una asignatura pendiente. Y no por falta de consumo, sino por una larga historia de ignorancia y desinterés.

Lo que la ciencia dice sobre la conciencia en peces

Durante mucho tiempo, se pensó que sentir dolor requería tener una corteza cerebral, como la que tienen los mamíferos. Y como los peces no la tienen, se asumió que no podían sufrir. Pero esta visión ha empezado a cambiar gracias a nuevas investigaciones en neurociencia y comportamiento animal. Hoy sabemos que los peces tienen cerebros distintos, pero no menos complejos. Muchas especies poseen estructuras que, aunque diferentes en forma, cumplen funciones similares a las de los vertebrados superiores. Pero más allá de lo que tienen dentro del cráneo, lo realmente revelador es cómo se comportan.

¿Tienen conciencia los animales?


Por ejemplo, los estudios de la investigadora británica Lynne Sneddon y su equipo han mostrado que truchas arcoíris a las que se les inyecta ácido acético en los labios desarrollan respuestas conductuales duraderas, como frotarse contra superficies duras, pérdida de apetito, inmovilidad y cambios en su comportamiento exploratorio. Sin embargo, lo más revelador es que dichas reacciones disminuyen o desaparecen si se administra un analgésico, lo que sugiere una experiencia modulada de dolor, y no una mera respuesta refleja. Es decir, no solo sentían, sino que esa molestia podía aliviarse.

Además, estudios en peces cebra, tilapias, doradas o cíclidos han demostrado capacidades cognitivas avanzadas. Se ha documentado en ellos aprendizaje por observación, memoria espacial, reconocimiento individual y toma de decisiones estratégicas. Observaciones que apuntan a una vida mental más rica y sensible de lo que tradicionalmente se ha asumido.

En 2011, un equipo de investigadores brasileños expuso peces cebra a distintos tipos de estímulos estresantes para ellos. ¿Qué ocurrió? Los peces comenzaron a evitar zonas abiertas, permanecían inmóviles más tiempo y reducían su actividad. Son cambios de comportamiento similares a los observados en mamíferos con síntomas de ansiedad. Y lo más interesante: esos cambios se mantenían en el tiempo y variaban según la historia individual de cada individuo.

¿Se sienten solos los peces?


Incluso se ha observado que algunos peces muestran lo que se llama “fiebre emocional”, también conocida como fiebre psicógena o hipertermia, donde aumenta la temperatura corporal debido al estrés emocional y no por una infección o enfermedad. Investigadores de la Universitat Autònoma de Barcelona observaron que peces cebra sometidos a un estrés previo preferían situarse en aguas más cálidas que aquellos sin ese estímulo estresante.

Puede haber conciencia sin corteza

La idea de que la conciencia depende exclusivamente de la corteza cerebral ha sido cuestionada por muchos neurocientíficos en la última década. Se ha demostrado que la conciencia no depende de una estructura específica, sino de redes funcionales que pueden estar presentes en cerebros muy distintos al nuestro. La Declaración de Cambridge sobre la Conciencia, firmada en 2012 por un grupo internacional de neurocientíficos, afirma que muchos animales no humanos, incluidos los peces, probablemente poseen los sustratos neurológicos necesarios para tener experiencias conscientes.

Esto no significa que los peces piensen como nosotros, o que su dolor sea idéntico al dolor humano. Pero sí implica que pueden experimentar sufrimiento de forma significativa para ellos, y por tanto, merecen consideración moral. La conciencia no es un fenómeno exclusivo de primates ni de mamíferos; es una propiedad evolutiva que puede surgir de múltiples formas en la naturaleza.

Si aceptamos esta posibilidad, o si no la descartamos, la pregunta que sigue es inevitable: ¿no deberíamos actuar con cautela y proteger a estos animales como lo hacemos con otros vertebrados?

¿Cómo se certifica el bienestar de los peces de acuicultura?


Un gran vacío legal en Europa

Pese a esta creciente evidencia científica, la legislación europea sigue siendo ambigua y limitada en cuanto al bienestar de los peces. El artículo 13 del Tratado de Funcionamiento de la Unión Europea reconoce a los animales como “seres sensibles” y establece que las políticas comunitarias deben tener en cuenta su bienestar. Sin embargo, este reconocimiento se aplica de forma desigual: existen directivas específicas y obligatorias para animales terrestres, pero no para peces.

En el caso de la acuicultura, la Autoridad Europea de Seguridad Alimentaria (EFSA, por sus siglas en inglés) ha emitido recomendaciones técnicas sobre buenas prácticas durante el transporte y el sacrificio de peces en los años 2009 o 2020, pero estas directrices no tienen carácter vinculante. En otras palabras, los Estados miembros no están obligados legalmente a seguirlas.

Muchos países de la Unión Europea permiten todavía métodos de sacrificio que la comunidad científica considera crueles. Por ejemplo, se sigue utilizando el desangrado sin aturdimiento, la asfixia fuera del agua y métodos mecánicos como el golpe en la cabeza (percussive stunning) que no siempre se aplican correctamente. En algunos casos, los peces pueden tardar minutos o incluso horas en morir, lo cual sería inaceptable en cualquier otro animal de granja.

Esta falta de regulación contrasta con los avances logrados en otros sectores ganaderos. Para cerdos, aves o vacas, existen normas claras y exigibles que prohíben causar sufrimiento innecesario y establecen estándares de manejo. ¿Por qué los peces siguen siendo una excepción?

¿Los peces sufren? Por si acaso, la ciencia intenta sacrificarlos sin dolor


Un sufrimiento invisible pero real

Parte del problema radica en cómo percibimos a los peces. No emiten sonidos que podamos reconocer como gritos, no expresan emociones en su rostro y habitan un medio físico que nos resulta ajeno. Esta “distancia empática” ha facilitado que su sufrimiento permanezca invisible, tanto para los legisladores como para los consumidores.

Bajo el agua reina lo que podríamos llamar El sonido del silencio, parafraseando la icónica canción de Simon & Garfunkel: una ausencia de voces que defiendan su causa, una indiferencia social y política ante su posible sufrimiento. Pero el hecho de que no escuchemos su dolor no significa que no exista.

Desde un punto de vista biológico, muchas especies de peces poseen sistemas nerviosos complejos, con nociceptores (receptores del dolor), redes neuronales organizadas y capacidades cognitivas que van mucho más allá de la simple supervivencia. Algunos estudios incluso han documentado el uso de herramientas, el reconocimiento de sí mismos en espejos (en algunas especies como el lábrido limpiador) y vínculos sociales duraderos.

La forma en que se sacrifican actualmente muchos peces no resiste un análisis ético. La asfixia fuera del agua, por ejemplo, es uno de los métodos más utilizados, y puede implicar una lenta agonía. Otras prácticas, como el enfriamiento en hielo vivo o la exposición al CO₂, tampoco garantizan una pérdida de consciencia inmediata.

¿Electricidad o hielo? Cómo sacrificar a un pez sin causarle dolor


Una llamada a la acción

La buena noticia es que no estamos obligados a seguir ignorando este problema. Hay soluciones técnicas disponibles para reducir el sufrimiento, como sistemas de aturdimiento eléctrico o mecánico adecuados, mejores prácticas en transporte y estándares de manejo más humanos. Solo falta voluntad política y presión social.

Ante esta situación, muchos expertos en ética animal, neurociencia y bienestar están reclamando un cambio legislativo urgente. Instituciones como el FishEthoGroup, eñ Eurogroup for Animals o Compassion in World Farming han lanzado campañas públicas para exigir a la Unión Europea que legisle sobre el bienestar de los peces.

Implementar estas medidas no solo es una cuestión de ética, sino también de sostenibilidad y salud pública. El sufrimiento previo al sacrificio influye en la calidad del producto final: un pez estresado libera más cortisol) lo que afecta la textura y el sabor de su carne. Además, los consumidores están cada vez más informados y preocupados por el origen ético de los alimentos.

La ciencia ya ha hecho su parte: ha demostrado que muchos peces son seres sintientes, con capacidades cognitivas y emocionales que no pueden ser ignoradas. Ahora le toca a la política responder. Mientras tanto, cada uno de nosotros, como ciudadanos y consumidores, también puede tomar decisiones más informadas: exigir transparencia, apoyar la investigación y elegir prácticas alimentarias más responsables. La pregunta fundamental no es si pueden sufrir sino por qué seguimos actuando como si no lo hicieran.

Es hora de que las leyes reflejen lo que la ciencia ya ha demostrado. Y también es hora de que, como ciudadanos y consumidores, empecemos a escuchar ese silencio bajo el agua.
