Steve Ayan in Scientific American:
1. Your perspective on yourself is distorted.
Your “self” lies before you like an open book. Just peer inside and read: who you are, your likes and dislikes, your hopes and fears; they are all there, ready to be understood. This notion is popular but is probably completely false! Psychological research shows that we do not have privileged access to who we are. When we try to assess ourselves accurately, we are really poking around in a fog.
Princeton University psychologist Emily Pronin, who specializes in human self-perception and decision making, calls the mistaken belief in privileged access the “introspection illusion.” The way we view ourselves is distorted, but we do not realize it. As a result, our self-image has surprisingly little to do with our actions. For example, we may be absolutely convinced that we are empathetic and generous but still walk right past a homeless person on a cold day.
The reason for this distorted view is quite simple, according to Pronin. Because we do not want to be stingy, arrogant or self-righteous, we assume that we are not any of those things.
