After reading a bit of evolutionary psychology, I realized to my astonishment that humans have evolved to survive, and not to be perfectly rational. Rational so much so its useful. I'm actually convinced that extreme rationality has evolutionary disadvantages. When you realize the universe has no meaning, does it motivate you and your species to keep breeding and take risks? As Schopenhauer said, if you truly considered all the costs associated with having kids before having them, no rational being would ever have kids! No person thinking clearly would ever trade 10-15 minutes of feeling good for a lifetime of costs and responsibilities. Then there's tribalism and ingroup and outgroup psychology which dictates much of what we see. These are survival mechanisms meant for living in small tribes, malfunctioning in a globally connected civilization. I would suggest yuval harrari's recent article on how humans are hackable and how that completely demolishes our concepts of liberal democracy , free market etc which assumes rational actors behaving in their self-interest.
