ELI5: Why Scaring People feels so rewarding?
gpt
**TL;DR: Power.**

A big part of our social structure is based on one person having power over other people. Most of us either want to lead, are jealous of the leader, or understand we're not the right person to be that leader.

We see this in a lot of other animals like horses and sheep. The large-and-in-charge 'stallion' or 'ram' gets the girls and leads the pack by showing their power.

Scaring someone - making them react in a startled way - shows you have some power over them, and gives you a little jolt of satisfaction when you do it. Applies just as much when we're young and just figuring things out as when we're older.
