Center of the universe bias is the assumption that other people are always looking over your shoulder. If you see something, or do something, instantly every other human being is aware. And, judging you.
For example, when you’re walking and you trip on the sidewalk. After which you scan the ground for the closest, hopefully excessive, crack. You curse at it, then at politicians, and if it’s icy, you curse the weather.
Back in reality, nobody saw you trip. And nobody saw your subsequent skit.
You’re the only one in attendance ninety-nine percent of the time.
So, next time you’re worried about other people, take solace in the likelihood that nobody has a clue.
