This is a rational analysis of a non-rational problem.

"Risk aversion" is the closest term I can find in common use. "Oh, this might be wrong!" or "Oh, someone might criticize me!" become risks you're unwilling to run. "If I give a talk about my idea, people might make fun of it!"

Everyone goes through this. Instead of thinking about it even more, Kerkour needs to work on his emotions. There's no shame in it. We're all afraid.
