Shane Parrish

Parrish is the author of The Great Mental Models Volume 1 — General Thinking Concepts and the host of The Knowledge Project podcast at Farnam Street (fs.blog). In Kyle’s corpus he functions as the modern systematizer of Charlie Munger’s “latticework of mental models” thesis: his mental-models book is read as “Shane Parrish’s explicit attempt to organize the latticework Munger argues for,” a direct progenitor-to-curriculum line from Poor Charlie’s Almanack. While annotating Munger’s “Elementary Worldly Wisdom” talk, Kyle’s own margin note asks “How does Shane Parrish think about this with his ‘mental models’ books?” — making Parrish the explicit bridge between Munger and the practitioner’s curriculum.

His ideas show up as load-bearing citations elsewhere. In The Great Mental Models he uses John Muir’s line (“When we try to pick out anything by itself, we find it hitched to everything else in the Universe”) to argue for second-order/systems thinking, and his journaling passage on self-feedback (“Keeping a journal of your own performance is the easiest and most private way to give self-feedback… painful for the ego, which is also why it helps build a Circle of Competence”) anchors Kyle’s What’s In a Post-Mortem - Research notes on reflection and post-mortems. He is also the interviewer of Naval Ravikant on The Knowledge Project Ep. #18 (Naval Ravikant — The Angel Philosopher).

Context: Shane Parrish is a Canadian writer and former intelligence-agency employee who founded Farnam Street (fs.blog), an influential blog and brand focused on mental models, decision-making, and learning, and hosts The Knowledge Project podcast.
