020 | Mental Models 3: Fantastic Biases and Where To Find Them

November 5, 2019

This is part 3 of the series on Mental Models, in which Gianluca and Jared discuss the cognitive biases that often impede aspiring rationalists. They discuss the idea of “System 1 and 2” thinking as a framing for the entire discussion, before exploring 12 of the most deadly thinking traps and how to avoid them. This includes everything from the Planning Fallacy and Anchoring, to more esoteric pitfalls that are yet to be named. Finally, they describe meta-biases—like the Bias Blindspot and the Fallacy Fallacy—equipping your mental toolkit with everything you need to upgrade your thinking.

019 | Mental Models 2: How To Think Like A Bayesian, Avoid Black Swans, & Know The Value of Your Decisions

October 28, 2019

This is part 2 of our series on Mental Models. In it, we’re bringing you the most useful and applicable models we’ve encountered in everything we’ve read, heard or seen over the years! In part 2 we unpack models from Bayesian reasoning, calibration, and expected value. We also cover fat-tailed distributions, counterfactual reasoning, inversion, and red-teaming. Throughout, we build up each model with examples and motivations, and often found ourselves making previously unseen (by us) links to other models which gave us several new insights. We hope this conversation will do the same for you!

This is part 1 of a new series on Mental Models - tips, tricks, and tools to add to your mental toolbox. In this episode we introduce the concept of a mental model but then quickly dive in to explanations of the most powerful models we’ve encountered. Join us and learn how to make better decisions (or know when a decision is not worth making), how to have more original and impactful ideas (and how to find the most promising ideas to work on out of the thousands you’ll soon have), and when tidying up your messy desk is just plain wrong (sorry, Marie Kondo!)
