Self-knowledge is the cornerstone of human identity. Without it, we wouldn’t be able to construct a logical story of who we are, which would make our experience of life, and interactions with others, chaotic, irrational, and unbearable. And yet, self-knowledge is a hard skill to master, with research suggesting that only 10-15% of people are self-aware. In fact, if there is one consistent finding in the history of psychology, it is that self-deception is far more common than self-knowledge.
