The shame lingers not because the incident was disastrous, but because it nudged against something deep: our phobia of not fitting in, of being seen as stupid, of not having social capital. And though those anxieties are correct on some primal survival level, they're completely disproportionate to most contemporary situations.
The irony is that these moments make us more lovable, not less. People tend to trust those who can laugh at themselves and rebound from mistakes. But the brain at 2 A.M. doesn't care about perspective, instead, it's replaying a loop of that quality you called your teacher in class.
Finally, being publicly incorrect humiliates us because it momentarily shatters the armor around the self-image we present to the world. And those late-night rewinds? That's just your brain, wrongly trying to "protect" you from repeating the error, while keeping you awake all night in the process.
