 As negative information tends to outweigh positive information, proximity may predict a failure to form friendships even more so than successful friendship formation.One explanation that has been put forth as to why such a negativity bias is demonstrated in social judgments is that people may generally consider negative information to be more diagnostic of an individual's character than positive information, that it is more useful than positive information in forming an overall impression.This is supported by indications of higher confidence in the accuracy of one's formed impression when it was formed more on the basis of negative traits than positive traits.
