One question that started it all: is brainy really the new sexy? In this milestone retrospective, Ben revisits the full arc of The Deductionist podcast. What began as a question about intelligence versus the performance of intelligence has grown into one of the most scientifically grounded behaviour and deduction shows available anywhere. This episode is the case file review. The debrief before the next chapter. Covered in this episode: How the show's central thesis formed around Jonathan Haidt's research on moral reasoning and post hoc rationalisation. Why most people are bad at observation, and why that has nothing to do with intelligence. The inference cycle, and the difference between a guess and a genuine deduction. Memory as an engineering problem, from Nelson Cowan's working memory research to the method of loci documented by Cicero. Why the popular mythology around body language is almost entirely wrong, and what Bella DePaulo's meta analysis actually showed. The Nicola Bulley case as a live study in how online communities reason under uncertainty. The emotional recession, Gallup's global data, and what Sherry Turkle's research on the flight from conversation tells us about where we are headed. Antonio Damasio's somatic marker hypothesis and why suppressing emotion does not make you more rational. What 221 episodes has actually taught about the unified nature of the deductionist skill set. 221b is coming.
