Most people are surprisingly bad at spotting fake smiles. One possible explanation for this is that it may be easier for people to get along if they don't always know what others are really feeling.Although fake smiles often look very similar to genuine smiles, they are actually slightly different, because they are brought about by different muscles, which are controlled by different parts of the brain.Fake smiles can be performed at will, because the brain signals that create them come from the conscious part of the brain and prompt the zygomaticus major muscles in the cheeks to contract. These are the muscles that pull the corners of the mouth outwards.Genuine smiles, on the other hand, are generated by the unconscious brain, so are automatic. When people feel pleasure, signals pass through the part of the brain that processes emotion. As well as making the mouth muscles move, the muscles that raise the cheeks – the orbicularis oculi and the pars orbitalis – also contract, making the eyes crease up, and the eyebrows dip slightly.Lines around the eyes do sometimes appear in intense fake smiles, and the cheeks may bunch up, making it look as if the eyes are contracting and the smile is genuine. But there are a few key signs that distinguish these smiles from real ones. For example, when a smile is genuine, the eye cover fold - the fleshy part of the eye between the eyebrow and the eyelid - moves downwards and the end of the eyebrows dip slightly.Scientists distinguish between genuine and fake smiles by using a coding system called the Facial Action Coding System (FACS), which was devised by Professor Paul Ekman of the University of California and Dr Wallace V. Friesen of the University of Kentucky.

大多数人都奇怪不善于发现虚伪的笑容。一个可能的解释是它可能更容易相处，如果他们始终不知道别人真的感觉。尽管虚伪的笑容看起来往往非常类似于真诚的微笑，他们实际上是稍有不同，是因为他们都带来的不同的肌肉，由大脑的不同部分。虚伪的笑容可以执行，因为创建它们的大脑信号来自于大脑的意识到部分和提示的 zygomaticus 主要肌肉收缩的双颊。这些都是肌肉，拉嘴向外的角落。真诚的微笑，另一方面，生成的无意识的大脑，所以是自动的。当人们感到很荣幸时，信号通过大脑处理情感的一部分。以及使肌肉移动的嘴，提高 — — 眼轮匝肌和帕斯额骨的面颊肌肉也合同，使眼睛皱起来和眉毛底略。中激烈虚伪的笑容，有时未出现眼睛四周的线条和面颊可能束起来，使它看起来好像眼睛承包和微笑是正版。但有几个关键的迹象表明，这些微笑分辨真正的和。例如，当一个微笑是真实的眼盖折叠-手部的眉毛和眼睑之间的眼睛-向下移动和眉毛结束蘸略。科学家区分真假的微笑，通过使用一个叫做面部动作编码系统 (流式），，想出了加利福尼亚大学的教授 Paul Ekman 和肯塔基大学的博士华莱士五.Friesen 的编码系统。
