電視里我們常會看見這樣一個場景，一群女孩穿著短裙有說有笑地在大街上走過，把路人們都看傻了，其實單個來看，她們的長相并不出眾，可是湊在一起就顯得青春貌美，這就是“啦啦隊效應”——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”.

當你看見女孩或男孩成群結對在一起時，覺得他們看起來都很辣，但單個來看的話，就沒那么迷人了。這就叫作“啦啦隊效應”。

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.

在許多人眼中，啦啦隊員們又漂亮又性感。然而，她們的美有一部分是視覺上的幻象。任何一個啦啦隊員在隊伍中看起來都要比單獨看時迷人得多。

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.

新研究發現，人的臉放在群體中比單獨來看顯得更迷人。所以如果你想讓社交網站上的頭像顯得漂亮，就選一張和朋友的合照吧。

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：我希望我能長得像那些女孩一樣漂亮。

乙：親愛的，那是啦啦隊效應，如果你單個來看她們，你會發現她們長相都很一般。
