Summary of Shane Parrish & Rhiannon Beaubien's the Great Mental Models Volume 1 by...

Please note: This is a companion version & not the original book. Sample Book Insights: #1 The first nine mental models in this book are about how the world works. They are representations of how something works, and they help you understand and think about your world. They are essential to making rational decisions, even when there is no clear path. #2 To see a problem for what it is, you must first break it down into its substantive parts. This bottom-up perspective allows you to expose what you believe to be the causal relationships and how they will govern the situation. #3 The biggest obstacle to learning from contact with reality is ourselves. It's difficult to understand a system we are a part of because we have blind spots that prevent us from seeing what we aren't looking for and what we don't notice. #4 We fail to update our beliefs from reality due to three things: not having the right perspective, ego-induced denial, and distance from the consequences of our decisions.
