“This chapter has shown why it's evolutionarily adaptive for humans to have a distorted perception of reality, such that people believe themselves to be more altruistic than they actually are. Our “self-deceptive altruism” helps explain the substantial confusion over the nature of human nature. It also sheds light on why political scandals perpetually shock both the public and the perpetrators themselves. Finally, self-deception over self-interest explains the similarities in authoritarian governments on both extremes of the spectrum.”
