你知道什么是啦啦队效应吗？　　电视里我们常会看见这样一个场景，一群女孩穿着短裙有说有笑地在大街上走过，把路人们都看傻了，其实单个来看，她们的长相并不出众，可是凑在一起就显得青春貌美，这就是“啦啦队效应”——cheerleader effect。
　　　　When you see a group of girls or guys and they look hot, but when you see each person individually they are NOT.
This is called “cheerleader effect”.
　　当你看见女孩或男孩成群结对在一起时，觉得他们看起来都很辣，但单个来看的话，就没那么迷人了。
这就叫作“啦啦队效应”。
　　To many, cheerleaders are beautiful and sexy.
However, their perceived beauty is in part a visual illusion.
Any one cheerleader seems far more attractive when she is with her team than when she is alone.
　　在许多人眼中，啦啦队员们又漂亮又遥。
然而，她们的美有一部分是视觉上的幻象。
任何一个啦啦队员在队伍中看起来都要比单遥看时迷人得多。
　　New research shows that individual faces appear more attractive when presented in a group than when presented alone.
Therefore if you want your profile picture on social media sites to be perceived as attractive, opt for a group shot with friends.
　　新研究发现，人的脸放在群体中比单遥来看显得更迷人。
所以如果你想让社交网站上的头像显得漂亮，就选一张和朋友的合照吧。
　　Example:　　A: I wish I looked like those girls.
　　B: Honey that’s the cheerleader effect, if you see them individually you will realize they are just plain Janes.
　　甲：我希望我能长得像那些女孩一样漂亮。
　　乙：亲爱的，那是啦啦队效应，如果你单个来看她们，你会发现她们长相都很一般。
