The Deep Dive: A Podcast About Everything
S3E5 - Heuristics as Evolutionary Design Features
Welcome to the Deep Dive: this episode explores why simple mental shortcuts — fast and frugal heuristics — can outperform complex statistical models in noisy, uncertain environments. We examine vivid case studies (like Kalahari Bushman trackers and an emergency-room triage that beats a 19-variable algorithm), theoretical tools (bias–variance trade-off, the recognition heuristic), and evolutionary accounts (error management theory and ecological rationality). Key points: heuristics are often adaptive features, not flaws; ecological fit determines success; asymmetric error costs shape biases; and simple rules can be more robust than complex models in large, uncertain “real-world” problems. The episode closes wit...

S3E4 - Resource Rational Metareasoning
Welcome to the Deep Dive: this episode explores why thinking isn’t free and how our minds make effective decisions under limited time and mental energy. Using the Deep Blue vs. Kasparov match as a launching point, the host walks through bounded rationality, Herbert Simon’s satisficing, and modern resource-rational models that reframe biases as efficient adaptations. The episode covers meta-reasoning and the value of computation (VOC), neural evidence for effort tracking, the model-based vs. model-free arbitration, and an AI analogy (Monte Carlo Tree Search) that mirrors human selective thinking. It also discusses cognitive switching costs and evol...

S3E3 - Predictive Processing & the Bayesian Brain
This episode unpacks the Bayesian brain and predictive processing: how the brain builds hierarchical generative models, minimizes prediction error and free energy, and uses precision (neuromodulators like dopamine, acetylcholine, norepinephrine) to weight surprises. It opens with the pilot "black hole" illusion and other real-world examples to show perception as active prediction. Hosts and expert commentary explore active inference versus classic reinforcement learning, how dysregulated prediction can produce hallucinations and delusions, empirical and pharmacological evidence, major critiques of the framework, and a practical sensory prediction journaling exercise you can try. Key takeaways include the roles of...

S3E2 - Dual Process Theory Under Strain
In this episode we unpack dual process theory (DPT) — the idea that human thinking runs on two interacting modes: fast, automatic intuition (System 1) and slow, effortful reasoning (System 2). Hosts explore the classic bat-and-ball example, boundary conditions where the model breaks down (expertise and emotion/pressure), and the neuroscience showing different but interacting brain networks. They discuss signal detection theory and the speed-accuracy tradeoff, how stress and emotion shift decision criteria, and real-world implications for fields like medicine and aviation. The episode closes with a practical "Cognitive Gearbox" exercise (breathe, reframe, commit/iterate) to help listeners pause and choose the ri...

S3E1 - Why Rationality Was Always Conditional
Welcome to The Deep Dive. In this episode we unravel why perfectly logical systems can still fail when their assumptions clash with the messy, adaptive real world. We trace the arc from classical models of rationality (homo economicus, expected utility, and Bayesian coherence) through Kahneman and Tversky’s discovery of systematic cognitive biases and prospect theory, to Herbert Simon’s bounded rationality and satisficing, and Gerd Gigerenzer’s ecological rationality. We also cover Steven Pinker’s defense of human rational capacity and the tension between individual goals and the public truth-seeking commons. Through stories—like a revenue-optimizing airline al...

S2E06 - Civil Society Under Pressure
Today, we examine how modern authoritarians undermine civil society by making participation in independent institutions costly, rather than outright banning them. Specifically, we highlight recent executive actions in the United States that have targeted law firms, universities, and students, arguing these actions are driven by personal grievances and an intent to suppress dissent. This approach is exemplified by freezing university funding, canceling student visas based on political speech, and pressuring law firms for representing disfavored clients. We also draw comparisons to tactics used in Hungary, Turkey, and India, where similar strategies of legal and financial pres...

S2E05 - Elections Under Federal Pressure
In this episode, we look at a significant clash between federal authority and state sovereignty regarding election administration, primarily focusing on a sweeping executive order and the Justice Department's demands for voter data. We highlight how a federal judge blocked key provisions of the executive order, such as requiring proof of U.S. citizenship for voter registration and banning the counting of mail ballots arriving after Election Day, citing their likely unlawfulness and unconstitutionality. Finally, we tie this all back to the broader trend towards democratic backsliding that we observe today.
