Robert Cialdini

A psychologist of persuasion whose work runs through Kyle’s notes as a touchstone for the mechanics of influence. In Poor Charlie’s Almanack, Charlie Munger credits Cialdini’s book with the “push” that sent him through three psychology textbooks to build his own checklist of the psychology of misjudgment; Munger recounts in detail Cialdini’s famous compliance experiment — asking strangers for an absurdly large commitment (two years supervising juvenile delinquents), then following up with a smaller “will you at least take them to the zoo one afternoon?” — which tripled the acceptance rate by triggering the subconscious reciprocation-of-a-concession tendency. His commitment-and-consistency and incentive-caused-bias ideas appear directly in Munger’s framework, which is why Cialdini’s Influence sits on Munger’s recommended-reading list as a books-to-read anti-library entry.

Across the essays-research notes, Cialdini is cast as a source on persuasion and information warfare: The Storytelling of Investing - Research places Influence alongside Richard Brodie’s Virus of the Mind on Bill Gurley’s reading list and links Cialdini to Memetics, while Open-Source Knowledge - Research treats his principles (with Dale Carnegie’s) as the classic social-engineering playbook now running at internet scale and always-on intensity.

Context: Robert Cialdini is an American social psychologist, professor emeritus at Arizona State University, best known for his 1984 book Influence: The Psychology of Persuasion. It codified six principles of persuasion — reciprocity, commitment/consistency, social proof, authority, liking, and scarcity (he later added unity).

Where this appears

• Poor Charlie’s Almanack — Munger credits Cialdini’s book for prompting his self-taught psychology synthesis; recounts the door-in-the-face reciprocation experiment.
• Influence — Cialdini’s Influence listed in Kyle’s anti-library as a Munger recommendation.
• The Storytelling of Investing - Research — Influence on Bill Gurley’s information-warfare reading list; Cialdini tied to memetics.
• Open-Source Knowledge - Research — Cialdini’s persuasion principles as classic social-engineering tactics scaled by the internet.
