Pratfall Effect

When students were asked to rate the attractiveness of high and average-performing quiz-takers, their ratings changed drastically when quiz-taker made a small blunder -spilling coffee on themselves. 

Participants rated high-performers much higher, and average-performers much lower in attractiveness. 

We find it endearing when people we admire make mistakes, but judge mediocre performers more harshly.
