You Are Not Alone In Your Delusion
We suffer from a bias that tricks us into believing our opinions are the norm. Most people mistakenly assume their personal choices and beliefs are shared by the majority of others.
This psychological quirk explains why we feel shocked when someone disagrees with us on basic issues. We subconsciously project our own internal logic onto the rest of the world, assuming others see things exactly as we do. It creates a false sense of security that our worldview is universally correct. Understanding this bias is key to seeing the true diversity of human thought.
