Ten people loved it, one person didn’t, and guess whose comment you memorized word for word.

Criticism sticks harder than praise because attention is built to track threats rather than compliments. The single negative comment feels like the real verdict while the ten good ones feel like politeness, though there is no reason to think the critic was the more honest person in the room. What you are experiencing is a weighting error rather than information. Naming it as one helps.

Count the actual responses next time instead of going by which is loudest in your head. Keep the useful part of the criticism if there is one, then read the other ten again properly.
