Description from the site:
Farnam Street (FS) helps you master the best of what other people have already figured out. Together we will develop the mental models to understand how the world works, make better decisions, and live a more meaningful life.
In a world full of noise and expiring information FS is a place to step back and think about time-tested ideas. Not only will will help you remember how curious you were but we’ll help you think in a multidisciplinary way.
