On ne laisse rien passer aux gens qu’on n’aime pas …

… même leur démarche nous apparait insupportable, relève une étude que mentionnait Science Daily récemment:

Past research has shown that race or physical similarity can influence brain processes, and we tend to have more empathy for people who look more like us.

(…)

The researchers found that when people viewed someone they disliked, a part of their brain that was otherwise activated in "mirroring" — the right ventral premotor cortex — had a different pattern of activity for the disliked individuals as compared to the liked individuals.
