Do people who look better have less chances of getting into a brawl?

Ever pondered after such an incident, ways it could have been avoided or things that could have aggravated the situation... I thought... One point is looks... Do good looks provided them more chances of avoiding fights..?.. Like if the person looked at your face while talking and suddenly start responding more calmly..Or is it the anger that's going to affect your sight irrespective of the looks and make you see red... I'm not talking about physique which can scare the other party off... Just general facial looks, do they guarantee that whatever you do it'll be ok
