Friendship stings: Jealousy behind a close friend's extraordinary experiences
研究发现人们更容易嫉妒密友而非普通朋友的非凡经历，因为密友间更易进行比较；但隐瞒这些经历反而会加剧嫉妒，并影响消费意愿。
Abstract People believe that close friends will naturally share their positive feelings, such as the pleasure of extraordinary experiences. But is that true? We find that people are more likely to be jealous of close friends' extraordinary experiences than those of acquaintances (Study 1). This is because close friends (vs. acquaintances) are more likely to make comparisons, which ultimately leads to jealousy (Studies 2, 5). But this does not mean that keeping secrets from close friends is a better choice. The secrecy of our close friends' extraordinary experiences actually amplifies jealousy (Studies 3, 5), with implications for consumer purchase intentions (Study 4). These studies suggest that close friendships may sting you in some unexpected situations (i.e., extraordinary experiences).
