“Surely, there are nuances,” you argue. “I can’t classify myself as a singular type of personality, though I can see others I would classify simply.”
“That’s the nature of our worldview: We attribute complexity to ourselves and simplicity to others. So, when someone has a perceived failure, such as addiction, we reduce that personality to a simplistic category we can easily dismiss. Attributing simplicity to the lives of others is the root of prejudice and an easy guarantee of personal psychological security. We can quash our self-doubt by making the world around us easy to understand. Accepting a world of indisputable definition eliminates unanswerable questions.”
