Nathan Cofnas, the academic who recently drew widespread attention for exposing plagiarism allegations against Cambridge professor Jason Arday, returns to Brain in a Vat to discuss academic freedom, institutional conformity, and his own controversial departure from Cambridge.

Cofnas argues that universities create incentives for academics to conform, particularly when scholarship challenges prevailing political and moral assumptions. He recounts the backlash to his writing on race and intelligence, including student petitions, protests, complaints, and the lengthy Cambridge investigation that followed.

Can universities remain committed to free inquiry when students and administrators find certain conclusions offensive? Cofnas contends that academic institutions must distinguish between social norms and punishment, and that protecting truly open inquiry requires tolerating ideas many people find objectionable.

Former Brain in a Vat producer Jimmy Mullen returns to discuss free speech in schools, exploring how educational institutions should balance student expression with their responsibility to maintain an environment conducive to learning.

Drawing on constitutional law and landmark cases on student free speech, the conversation explores viewpoint neutrality, the role of political disagreement in education, and the limits of school authority.

It ultimately considers how schools can prepare children to think independently while participating in a democratic society.

Colin McGinn joins to discuss sexual ethics on campus. Drawing on thought experiments and his own experiences in academia, McGinn argues that universities too often conflate harassment with consensual relationships while overstating the role of power imbalances. He explains why he believes current policies can undermine academic freedom, due process, and the proper limits of institutional authority.

Rivka Weinberg returns to argue that time is both the source of meaning and its greatest threat, making meaningful lives possible while also guaranteeing loss and impermanence. The conversation explores the relationship between suffering and meaning, whether ultimate meaning is attainable, and why temporary achievements may remain valuable even if nothing lasts forever.

Do adults have a right to decide what goes into their own bodies, even when experts believe they're making a mistake?

Jessica Flanigan returns to defend a radical idea: competent adults should have the freedom to access pharmaceuticals without needing permission from doctors or government regulators. Flanigan argues that the same principles underlying informed consent also support a right to self-medicate.

The conversation explores medical paternalism through debates over prescription requirements, addiction, public health, gender-affirming care, and assisted dying. We scrutinize the limits of state authority and whether doctors are ever truly better judges of our interests than we are ourselves.

We welcome back Stephen Kershnar to discuss the ethics of torture. Kershnar argues that some criminals deserve torture because severe wrongdoing can cause a person to forfeit protections against extreme punishment. He critiques the idea that there are moral constraints the state must never cross.

The dialogue also examines objections to torture concerning human dignity, bodily integrity, and the dangers of granting the state such power.

What happens to human beings in a world without scarcity? If all our needs were met, would we actually be better off? Will technological progress lead to utopia or collapse?

Humans are living through massive improvements in material conditions. More people have access to food, energy, and technology than ever before. Steven Kotler examines what this kind of abundance does to us. It may support a more comfortable life, but it can also erode the conditions that sustain a sense of purpose.

We also discuss how attention and identity are being affected by technological progress. As AI systems take on more optimization and decision-making, the role of human thought may change, raising questions about what remains distinctly human in how we engage with the world.

What does it mean to live with adversity? How ought we respond to the suffering of others? How can we adapt to hardship?

Adversity is a universal experience. Nearly everyone, at some point, faces physical, psychological, or social challenges, and yet suffering often goes unnoticed.

David Benatar joins us to discuss these questions on the human condition, provoked by his book 'Living with Adversity,' a collection of personal accounts of suffering.

Kevin Allison, creator of the RISK! podcast, recounts a high school prank at an all-boys Jesuit school in 1986. After a crush teased him by repeatedly spitting on him, Kevin later mailed him a sealed container of feces labeled “enjoy the cookies.”

In retelling the story, Kevin considers how the prank mixes humiliation and a possible form of intimacy, situated within his experience of growing up gay under Catholic doctrine. For Kevin, telling such stories has become an opportunity for self-reflection.

Beyond this, Kevin argues that sharing what is usually considered “unmentionable” can create a distinct form of connection: moments of vulnerability tend to draw listeners in rather than push them away. Thus, the points of greatest risk are often where an audience leans in most.

Clinical psychologist Chloe Carmichael, author of "Can I Say That?," examines how free expression relates to psychological well-being and social trust. Carmichael argues that suppressing disagreement drives resentment and misperception, rather than resolving conflict. She also scrutinizes the role of safe spaces, the spread of therapeutic language, and what limits on speech might be justified in public versus private life.
