This podcast episode explores the challenges of knowing ourselves, both in terms of character and competence. The speakers discuss how we overestimate our agency in the world and our own knowledge, leading to an illusion of understanding. They also highlight the invisibility of our flaws and foibles, as well as the unreliability of feedback from the world. Additionally, the speakers emphasize the role of self-deception and ego protection in hindering accurate self-knowledge. They also discuss the impact of social media on our self-awareness, highlighting both its potential for increasing self-awareness and the risks of epistemic trespassing, where people overestimate their expertise in areas outside their competence.
