Farnam Street
Farnam Street started back in 2009 with the goal of posting the best articles from around the internet on psychology, behavioral economics, human misjudgment, persuasion, and other subjects of intellectual interest.

LessWrong
The Less Wrong community aims to gain expertise in how human brains think and decide, so that we can do so more successfully. We use the latest insights from cognitive science, social psychology, probability theory, and decision theory to improve our understanding of how the world works and what we can do to achieve our goals.

The Leisure of the Theory Class
The Leisure of the Theory of Class is a blog devoted to speculation and ruminations on all aspects of economic and game theory.
