Here's my quick summary of The Elephant in the Brain: Hidden Motives in Everyday Life by @robinhanson and @KevinSimler. The big thesis is that we humans are strategically blind to key aspects of our motives, namely self-interest and in-group interest. 1/n The authors argue this self-deception seems to be a feature of the human brain, not a bug. Why do we deceive ourselves? In short, we’re much more effective at being selfish when we aren’t aware of our own selfish motivations. This blind spot is the Elephant in the Brain. 2/n
