Clearer Thinking is a podcast about ideas that truly matter. If you enjoy learning about powerful, practical concepts and frameworks, wish you had more deep, intellectual conversations in your life, or are looking for non-BS self-improvement, then we think you'll love this podcast! Each week we invite a brilliant guest to bring four important ideas to discuss for an in-depth conversation. Topics include psychology, society, behavior change, philosophy, science, artificial intelligence, math, economics, self-help, mental health, and technology. We focus on ideas that can be applied right now to make your life better or to help you better understand yourself and the world, aiming to teach you the best mental tools to enhance your learning, self-improvement efforts, and decision-making. • We take on important, thorny questions like: • What's the best way to help a friend or loved one going through a difficult time? How can we make our worldviews more accurate? How can we hone the accuracy of our thinking? What are the advantages of using our "gut" to make decisions? And when should we expect careful, analytical reflection to be more effective? Why do societies sometimes collapse? And what can we do to reduce the chance that ours collapses? Why is the world today so much worse than it could be? And what can we do to make it better? What are the good and bad parts of tradition? And are there more meaningful and ethical ways of carrying out important rituals, such as honoring the dead? How can we move beyond zero-sum, adversarial negotiations and create more positive-sum interactions?

Are stock prices set by cash flows or crowd vibes? Why do bubbles last if “smart money” can short them? What should retail traders learn from GameStop and zero-commission options? When does momentum make sense - and when does it burn you? Why don’t obvious mispricings get fixed - what actually stops arbitrage? Will AI help us think clearer, or supercharge manipulation and personalized pricing? Where should regulators draw the line on gamified trading and price discrimination? Do tariffs feel good because they keep others out—even if we pay more? What does the "winner’s curse" mean for auctions, IPOs, and everyday deals? How much of what we want is copied from other people, and why does that matter for markets?
 
Alex Imas is the Roger L. and Rachel M. Goetz Professor of Behavioral Science, Economics and Applied AI and a Vasilou Faculty Scholar at the University of Chicago Booth School of Business, where he has taught Negotiations and Behavioral Economics.

What does “100x more good” mean relative to your current giving? How can your giving more closely align with your pre-existing values? If cost-effectiveness is the denominator we forget, what changes when dollars per outcome sit front and center? Can independent evaluators fix a charity market that rewards storytelling over outcomes? Greatest need, stronger evidence, cost per result, a wider moral circle, multipliers - how do each of these levers compare in your giving portfolio? How do self, passion, and effectiveness map cleanly onto your intrinsic values? How do you avoid bad compromises? When do risky policy bets beat reliable bed nets? How do you keep prevention’s invisible wins from being crowded out by visible cures and photogenic stories? What kind of pledge or trial would actually help you follow through and inspire others without preaching? If the biggest brands need your dollar least, where is it marginally decisive right now?

Can you do 100x more good? (with Sjir Hoeijmakers)

Note: Please note that in this episode, Spencer and Dr. O'Sullivan discuss a controversial and complex medical topic where the science is still in development and there is a lot of ongoing debate. We don't know whether or not the perspective that Dr. O'Sullivan expresses is correct, but the topic appears to be an important one as we look towards the future of neurophysiological diagnostics and treatment.
 
What changes when long COVID is split into medical damage, post-viral fatigue, misattribution, and psychosomatic mechanisms? When symptoms soar while tests stay normal, what should count as evidence? When do surveys without controls manufacture a syndrome we then chase? Does renaming “psychosomatic” to “functional” clarify or conceal? If long COVID and severe COVID affect different populations, what follows for causation and care? How do clinicians explain mind–body pathways without sounding dismissive? When is stopping more tests the most scientific decision? What actually helps once the testing spiral ends - graded activity, distraction skills, or non-reactive awareness? Can early diagnosis break fear–avoidance loops before habits harden? How should we meet chronic pain when anatomy is silent? If suffering is real and causes are mixed, how should we measure success?
 
Suzanne O'Sullivan is an Irish physician practising in Britain, specialising in neurology and clinical neurophysiology. In addition to academic publications in her field, O'Sullivan is an author of acclaimed non-fiction focusing on medical casework related to neurology and medically unexplained illness.

What is psychosomatic illness? (with Suzanne O'Sullivan)

What do we miss when we treat public shootings as the whole story of mass murder? If public events are a small slice, how should prevention and attention shift? Does saturation coverage turn tragedy into aspiration for the fame-seeking few? Do school “active-shooter” drills protect kids—or seed fear and imitation? Should reporting drop names and faces to starve the infamy motive? How should we talk about risk without distorting it? Can culture stop romanticizing guns without denying self-defense? Are the core drivers of public mass shootings nihilism, toxic self-regard, and a fascination with guns more than psychosis? If suicide removes the final barrier, how should that reshape prevention?Should screening target a narrow profile rather than broad traits with sky-high false positives? If most weapons used are legally owned, what levers actually matter - enforcement, registration, or smart-gun locks? Do “more weapons” predict fatalities better than weapon type, and what policy follows from that? What would it take for laws, norms, and platforms to make infamy harder to harvest? How do we design prevention that is specific, ethical, and effective?

What makes a forum truly open-minded rather than performative? When does listening change minds instead of just hardening identities? Are we teaching citizens to separate facts from frames? Do the best debates surface values as well as evidence? How can we reward calm argument over outrage economics? What reforms reduce polarization without dulling real disagreement? Should any topic be off-limits in a free society? Is philanthropy giving back—or building what’s missing? Should generosity optimize impact or express the values we want to grow? How much risk is acceptable when the upside is transformative?

What does rationality mean when life won’t fit a spreadsheet? If models demand one common scale, what happens to values that can’t be compared? Are we optimizing choices, or narrowing them to what’s easy to count? When do toy problems stop teaching us about real ones? Can preferences be “mapped” if the act of asking reshapes them? When is precision a disguise for guesswork? What standard should judge error when the world is fuzzy by design? If we want better decisions, should we start by choosing better frames? How do fast intuitions and slow reflection share the work when stakes are high? When should we pause because the first answer felt too easy? How can diverse perspectives expose what one mind won’t see? How do we weigh the uncountable without pretending it’s all commensurate? What does a life well chosen look like beyond being error-free?

Beyond the assumption that humans are rational (with Barry Schwartz)

Are the existential risks posed by superhuman AI fundamentally different from prior technological threats such as nuclear weapons or pandemics? How do the inherent “alien drives” that emerge from AI training processes complicate our ability to control or align these systems? Can we truly predict the behavior of entities that are “grown” rather than “crafted,” and what does this mean for accountability? To what extent does the analogy between human evolutionary drives and AI training objectives illuminate potential failure modes? How should we conceptualize the difference between superficial helpfulness and deeply embedded, unintended AI motivations? What lessons can we draw from AI hallucinations and deceptive behaviors about the limits of current alignment techniques? How do we assess the danger that AI systems might actively seek to preserve and propagate themselves against human intervention? Is the “death sentence” scenario a realistic prediction or a worst-case thought experiment? How much uncertainty should we tolerate when the stakes involve potential human extinction?

What does it mean to treat facts as drafts rather than monuments? If truth is something we approach, how do we act while it’s still provisional? When definitions shift, what really changes? How do better instruments quietly rewrite the world we think we know? Are we mostly refining truths or replacing them? When do scientific metaphors clarify and when do they mislead? What public stories make self-correction legible and trusted? What features make science self-correct rather than self-congratulatory? How should we reward replication, repair, and tool-building? Do we need more generalists - or better bridges between tribes? How does measurement expand the very questions we can ask? Is progress a goal-seeking march or a search for interesting stepping stones? Should we teach computing as a liberal art to widen its aims? Will AI turn software into a home-cooked meal for everyone? How do we design tools that increase wonder, not just efficiency?

What changes when we treat violence as a human problem rather than a demographic story? Are fear, anger, and shame the real levers behind sudden harm? How much agency can we ask of people shaped by chaos without ignoring that chaos? Where is the line between explanation and excuse? What would an honest narrative about community safety sound like? Do neighborhoods want fewer police, or different policing grounded in respect? How do we build cultures where accountability and care reinforce each other? If separation is required for rehabilitation, how do we keep it from becoming psychological punishment? How do we welcome people back into society without chaining them to their worst moment?

What changes when psychology stops naming traits and starts naming parts - can “entities and rules” turn fuzzy labels into testable mechanisms? If the mind is a web of governors with set points, what exactly is being controlled - and how do error signals become feelings? Are hunger, fear, and status-seeking all negative-feedback problems, and where do outliers like anger or awe fit? What would count as disconfirming evidence for a cybernetic view - useful constraint or unfalsifiable epicycle? Could a “parliament of drives” explain why identical situations yield different choices? And how would we measure the votes? Do abstractions like the Big Five help, or do they hide the machine under the hood? How many rules do we need before prediction beats metaphor? And could a new paradigm help make psychology a more mature and cumulative science?

How well do we identify with our past and future selves? What are some of the ways we can develop self-awareness and emotional control? How can we learn more and learn faster at a younger age? How can we best express emotions like sadness and anger? What are our intrinsic values, and what should they be?
