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?

Where else in the world have major UBI studies been run? What's the difference between "guaranteed income" and UBI? How do people in cash transfer studies tend to spend their money? Should restrictions be placed on what people can spend their study money on? How long does it take to see various effects of UBI or guaranteed income on a large scale? How does guaranteed income affect the nature of work in recipients' lives? How does guaranteed income affect a person's net worth in the long run? What are the effects on well-being? How does topical knowledge affect prediction accuracy in a given area? How good are subject-matter experts at making predictions about the outcome or utility of a study? How can such predictions in aggregate be used to shape future research? To what extent should reseachers express uncertainty when making proposals to policy-makers? How much of an effect does the publishing of academic papers have on the world? What kind of person should try to build a career in academia? How can non-experts assess the rigor and significance of academic papers?

Are narcissists born with narcissism? What are the core components of narcissism? To what extent do narcissists have their own personality that isn't shaped by what others think of them? Are narcissists overly confident or overly insecure? How are grandiosity and vulnerability related? Why might narcissists be offended by compliments? Would narcissists relinquish their narcissism if given the opportunity? Do most narcissists know that they suffer from Narcissistic Personality Disorder (NPD)? How long of a questionnaire is needed to diagnose NPD? In what professions are narcissists overly represented? How should people deal with the narcissists in their lives? How can narcissists be successfully integrated into society? What can people do if they think they might be a narcissist?

What do schools do well and not so well? In what contexts is memorization most effective? What's the value in teaching something that will probably be forgotten by most students after graduation? How should educators balance time spent on building skills versus acquiring knowledge? Why do students so often fail to apply the skills learned in school (e.g., fractions, solving for unknown quantities, etc.) to problems encountered in everyday life? What is "transfer of learning"? What is educational "directness"? How can we learn languages more efficiently? How does review compare to other forms of study or exam prep? How can we forget less of what we read? Is it really true that "practice makes perfect"? How can we best set ourselves up emotionally for optimal learning? What should people do when they hit plateaus in their learning?

Which of the world's hardest problems can be solved merely by gathering more data? Why are social problems harder to solve than biological problems? How should power between business owners and unions be balanced? Why do people so often misinterpret research results — sometimes even to the point of concluding exactly the opposite of what the results show? What heuristics should people use when reading research papers? How are culture wars affecting the reliability of research? Should there be any limits on what can be researched and published? When might left-leaning researchers actually end up causing harm to the groups whose causes they're trying to defend? How much does it matter that we know what sorts of traits are heritable? How important is IQ for predicting life outcomes? In what kinds of situations is skill more important than IQ, and vice versa? Is there value in knowing your own IQ?

What kinds of things really distort our ability to think clearly when making decisions? What is "psychological distance"? What is construal level theory? How can we intentionally increase or decrease psychological distance for ourselves or others who are making decisions? What are "decisionscapes"? When giving toddlers choices, we often artificially limit the number of available options to help smooth out the decision process and avoid decision paralysis. When might the imposition of this kind of artificial limitation be useful for adult decision-makers? What should we do with the productivity gains we've reaped (and will presumably continue to reap) from AI? Is it possible to show someone that you really care about them without making any kind of sacrifice? What has AI done to the value of art? Which individuals and companies currently own the means of digital production? How can we break free from algorithms that drive engagement by triggering negative emotions and promoting conflict? Is survivorship bias the ultimate cognitive bias? What are some lesser-known or lesser-used framing devices for making better decisions?

Is the placebo effect bullshit? Are "open-label" placebos just as effective as "closed-label" placebos? How do placebos differ from dummies? Is the placebo effect just a kind of scientific-sounding "woo"? How does social priming differ from word priming? Why is it important in research to have both placebo and no-treatment groups? What is the Hawthorne effect? What is the John Henry effect? When is it useful to express effect sizes using Cohen's d? If there's not a placebo effect, then what's really going on in cases where it seems like there is one? Is meditation a kind of placebo treatment for mental states? How can researchers believe that people's mental states are important and yet that the placebo effect doesn't exist? What is stress-induced analgesia? Does the nocebo effect (if it exists) provide reason to think that the placebo effect exists? Where do psychosomatic effects fit into this picture? What have animal studies found about the placebo effect?

What is Cognitive Behavioral Therapy (CBT)? What are the "cognitive" and "behavioral" parts of CBT? What are some of its most common techniques? What are "negative core beliefs"? What does CBT have to say about situations in which problems come from a person's environment rather than from within the person's mind? What makes a particular belief or behavior "good"? How do we know how effective various psychotherapeutic treatments are? How much can we rely on meta-analyses about psychotherapy treatments? Is CBT the most evidence-based psychotherapy treatment? What are CBT's main competitors? Is CBT significantly better than its competitors in all respects, or are there situations in which other treatment types have a significant advantage? How can you figure out exactly what a therapist does when they list a dozen different treatment modalities on their website? Can all treatment modalities be similarly effective if they have the right set of core components? How do antidepressants compare in efficacy to CBT? When should one, the other, or both in conjunction be used to treat a patient?
