ELI5 What is a Catch 22?
gpt
Imagine you're a pilot. The only way to get out of flying missions is to be certified insane. Additionally, if you demonstrate concern for your own immediate safety, you are certified sane. Sane people must fly missions.

You and your friend Orr are concerned that the mission you are about to go on is incredibly dangerous.

Orr is a crazy man. He talks to his bed. This means that he could easily get out of flying the mission by claiming insanity. But why would he want to get out of the mission? Because he is concerned for his own safety, and so is sane. So he must fly the mission.
