·45 min·4 clips

Harvard psychologist Steven Pinker reveals how shared cognition, not just intelligence, controls money, power, and your daily choices.

The episode begins with Jim Kwik introducing the topic of shared cognition as a hidden force behind societal phenomena. Guest Steven Pinker, a Harvard psychologist, defines common knowledge as a recursive state where individuals know that others know something, generated through public witnessing. Pinker illustrates how common knowledge forms the basis of money, government power, and social norms like driving rules. He explains that coordination, from ancient hunting to modern education, relies on these shared understandings. Pinker delves into nonverbal cues, such as eye contact, as evolutionary tools for creating common knowledge. The discussion shifts to social media, where Pinker analyzes cancel culture as a modern form of public shaming to enforce norms. He addresses misinformation, emphasizing the need for truth-seeking institutions like journalism and science. Pinker highlights cognitive biases from his book 'Rationality' and advocates for tools like Bayesian reasoning. The conversation explores AI's role in common knowledge, warning of sycophancy and fragmentation. Pinker discusses the dangers of too much transparency, using examples from relationships and diplomacy. He explains how revolutions ignite when common knowledge of dissatisfaction spreads, citing the Arab Spring. On cryptocurrency, Pinker distinguishes blockchain's ledger from speculative bubbles. Kwik asks about installing a mental upgrade; Pinker recommends meta-knowledge and self-awareness. The episode wraps with Pinker sharing learning from audience feedback and promoting his book.
