How To Pursue Goals without Striving (with Stephen Zerfas)
Read the full transcript here. Why can the same meditation technique produce emotional openness in one person and dissociation in another? How can meditators tell whether they are cultivating equanimity or merely numbing themselves? Why is meditation unusually difficult to teach compared with visible skills like tennis or music? Can live narration, experimentation, and tacit knowledge transfer solve meditation’s feedback problem? What can shifts in breathing, smiling, memory, and loving kindness reveal about the nervous system? How do practitioners learn to enter deeply blissful states without grasping for them? Are the jhanas distractions, training wheels, or powerful tools for lasting psychological change? How might altered states help reset emotional defaults around grief, anger, fear, and shame? Can meditation turn difficult emotions into useful information without suppressing them? Will nervous system mastery become more important as AI commoditizes cognition? Stephen Zerfas is the CEO and Co-founder of Jhourney — a tech startup scaling transformative meditation through a data-driven lens, guiding complete beginners into deeply absorbed meditation states known as the Jhanas, in less than a week.

Bicameral Minds and Leaderless Tribes (with Tor Parsons)
Read the full transcript here. What happens to a community when no one has the formally recognized authority to punish, exclude, or forgive? Are written rules a constraint on freedom, or are they sometimes the very condition that lets unusual people survive socially? When a group says it has no hierarchy, does that eliminate power, or merely disguise power as consensus, vibe, shunning, and informal reputation? Why does a leaderless community so often become a place where everyone watches everyone else? Is mob justice an aberration from human nature, or one of the oldest forms of social order? When people call for a world without cops, do they imagine a world without enforcement, or a world where enforcement has been redistributed into every friendship, feed, and campfire? Why do tight-knit groups sometimes seem humane, supportive, and morally serious from the inside, yet suffocating or terrifying to anyone who cannot fit the mold? If cancelation only works on people who once belonged to the in-group, what does that reveal about belonging itself? Is the arbitrary quality of online punishment a failure of justice, or the predictable result of a system where norms are enforced before they are named? Can a society make room for weirdness without first deciding, in writing or by custom, which kinds of weirdness it is willing to protect?

How Small Actions Rewrite Identity (with Eric Zimmer)
Read the full transcript here. What changes when we stop imagining transformation as a single breakthrough and start seeing it as thousands of small, low-resistance actions? How do we know whether a small action is genuinely sustainable or merely another form of self-improvement theater? What makes one habit a keystone habit for one person but irrelevant or even counterproductive for another? How can someone choose a direction for change when modern life constantly offers competing prescriptions for what a better self should look like? Why are the boring, repetitive, off-camera moments of change so much harder to honor than the dramatic moment of decision? What would recovery, habit formation, or personal growth look like if relapse and failure were treated as learning signals rather than moral verdicts? When does counting streaks reinforce commitment, and when does it turn a broken streak into a reason to abandon the whole project? How should we think about behaviors like social media use when they resemble addiction in loss of control but differ radically in risk, stigma, and physiology? What does addiction reveal about the way pain, relief, shame, and repetition can form a closed loop? Why might the same addictive mechanism be easier to recognize in a socially condemned drug habit than in a socially acceptable pattern of drinking, working, scrolling, or consuming?

The Twelve Levers for a better life (with Jeremy Stevenson)
Read the full transcript here. Why is so much self-help useless, and why is some of it genuinely life-changing? What separates a powerful psychological technique from vague advice? Why is “love yourself” often less useful than a concrete sequence of actions? How can insight into the causes of suffering become a path to change rather than just an explanation? When does understanding the past help, and when does it distract from the controllable patterns happening now? Why can a simple realization about approval-seeking, avoidance, or fear reorganize a person’s life? What does exposure therapy reveal about the gap between what the anxious mind predicts and what reality actually delivers? Why is the stretch zone so important for change? How do thoughts, attention, speech, and the body become the real machinery of self-improvement? And what would it mean to build a toolkit around what people can actually control?

The Hidden History of Evidence-Based Everything (with Helen Pearson)
Read the full transcript here. How do we know whether the things we do every day actually work? Why do so many practices in medicine, parenting, education, conservation, and public policy begin as intuition, authority, or anecdote rather than careful evidence? What can the tragic history of front-sleeping advice and sudden infant death syndrome teach us about the danger of untested conventional wisdom? How should we distinguish between a bad outcome, a bad decision, and a reasonable decision made under uncertainty? When does intuition work well, and when does it fail because we lack repeated examples, tight feedback loops, or meaningful outcome data? What makes randomized trials so powerful, and why are they still only one part of the evidentiary picture? How should we weigh anecdotes, observational studies, randomized trials, systematic reviews, meta-analyses, clinical guidelines, expert judgment, patient values, and political constraints? Why do people resist evidence when it threatens their identity, authority, or past decisions? What does evidence-based medicine get right that fields like education, policing, business, and conservation still struggle to embed? And in a world of social media, declining institutional influence, polarized trust in science, and AI-generated scientific output, how can we build better habits for finding, synthesizing, communicating, and acting on evidence?

Is cash a better form of charitable aid? (with Nick Allardice)
Read the full transcript here. How much good is lost when charity optimizes only for what can be measured? When does a cost-effectiveness model clarify reality, and when does it create false confidence? Could the most important interventions be the ones that look too uncertain, too political, or too indirect to fit neatly into a spreadsheet? What would it mean to judge philanthropy not only by the marginal dollar, but by its power to unlock whole systems of future impact? And if social change follows a power law, should doing good look less like buying guaranteed outcomes and more like building a portfolio of serious bets? Why might cash transfers be unusually powerful despite their simplicity? What happens when money does not just help one household, but circulates through an entire local economy? How should we weigh scalable, robust interventions against more complex programs that may work brilliantly only when execution is excellent? What do donors miss when they ignore team quality, government relationships, political context, and second-order effects? And in a world where every intervention sits inside a messy system, how do we stay rigorous without becoming trapped by certainty?

When painful thoughts feel true but aren't (with Christine Padesky)
Read the full transcript here. Why do our minds sometimes need experiments more than insight? What changes when therapy becomes a way of practicing life outside the therapist’s office rather than explaining life inside it? If CBT is fundamentally about learning skills, how much of good therapy depends on what happens between sessions? Why can a five-minute action matter when depression says that nothing is worth doing? What does it mean to test a thought instead of trying to replace it with something merely positive? How do moods make certain evidence visible while hiding the rest? Why does anxiety grow when we organize life around avoiding danger rather than strengthening our capacity to cope? What would change if we treated catastrophes not only as predictions to challenge, but as scenarios we could prepare to handle? How do safety behaviors keep fear alive by teaching the wrong lesson? And what might therapy become if it started not only with what is broken, but with the strengths, habits, and forms of resilience a person already has?

She has been recognized for her client-centered, collaborative, and strengths-based contributions to cognitive behavioral therapy (CBT).

Could an international agreement protect us from dangerous AI? (with Malo Bourgon)
Read the full transcript here. What are the world’s leading AI companies actually trying to build when they talk about superintelligence? Is the goal merely better chatbots, or systems that could outperform all humans across every cognitive task? Why would such a system be so alluring if it could accelerate medicine, science, education, abundance, and human flourishing? Why would it also create an unprecedented concentration of power for whoever controlled it? If intelligence includes not only abstract reasoning but persuasion, strategy, manipulation, planning, and technological invention, what happens when those capacities are automated at superhuman scale? How seriously should we take AI CEOs when they say the technology could go catastrophically wrong, and how should we interpret the tension between their public concern and their continued participation in the race? If we cannot reliably inspect their goals, motives, reasoning, or learned objectives, how could we know whether apparent obedience is real safety or just surface behavior? Even if alignment were solved, who should be trusted to steer a superintelligence? Could compute governance, chip tracking, training thresholds, inspections, and a US-China agreement buy time before the frontier moves further? What do nuclear weapons, nuclear power, chemical weapons, and germline engineering teach us about the possibility and limits of technological restraint? Is resignation itself part of the danger, and could a credible movement for coordination make a saner future more possible? averages? And when injustice affects both men and women differently, what framework avoids turning that into a zero-sum argument? Links: MIRI Malo Bourgon leads the Machine Intelligence Research Institute. Before becoming CEO, Malo served as a program management analyst and then as COO, helping implement many of MIRI’s current systems, processes, and program activities. Malo joined MIRI in 2012 shortly after completing a master’s degree in engineering at the University of Guelph.
