Neither the number of teeth we teach, nor the opening of the mouth, nor the white of the teeth. The key to know if a smile is true or feigned is in the eyes.

In this post of Lifestyle we are going to tell you some guidelines so you can distinguish one from another .A very useful skill, yes , but with certain emotional risks.Are you ready? Say “cheese”!

Origin of the intrigue

The interest in distinguishing a real smile from a forced one is not new.In fact, it was the French physician and researcher Guillaume Duchenne who published in 1862 the first study on the physiological differences between the two.

His method, though, was very" funny "for his patients, since the doctor used electric shocks to see the functioning of the muscles, but the conclusions were pioneers at the time and, in fact, gave name to the authentic smile: Duchenne's smile .

What does Science conclude?

The spontaneous smile is a consequence of a limbic process that causes the contraction of the muscles major and minor zygomatic near d e the mouth, authors of that we lift the corner of the lips, and the orbicularis muscle, near the eyes, which causes the rise of the cheeks and wrinkles next to the eyes.but, the pressure, in this case, can be such that it leads us to cry with laughter.Has it happened to you, right?

Also, in the fake smile you can see a slight asymmetry on the lips , which tend to rise more on one side, while the authentic one usually appears moments after the moment that motivates them, is gradual and lasts longer.

No everything that glitters is gold

With these indicators, do you feel able to distinguish whether a smile is real or fake?

It's not that easy.There are many situations in which we can use a real smile : to be educated, if we are frustrated or even to show our response to something absurd or outrageous.

This is what the research of the Massachusetts Institute of Technology gathers., which has developed a computer program able to detect the origin of the smile.

Do not forget the social factor , since not every smile caused a negative feeling , or vice versa.Maybe the person in front of you shows you an authentic smile, but for the hat so ridiculous that you wear and not because it is glad to see you.On the contrary, you may receive a smile forced at one point because that person has a bad day, but he has been kind enough to show you his best face.

And the smile has become a great social tool , a vehicle to fit, be accepted and make a good impression.In fact, Dartmouth College in Hanover (USA) has conducted a study in which it concludes that the politicians who they appear with a real smile on the electoral posters they are more successful at the polls than those who use a forced one, and there are many actors who receive classes to improve this gesture in their performances.

And we couldn't say goodbye to an article about smiles without mentioning the most famous and enigmatic : the Mona Lisa.Do you dare to give your verdict? Real or false?
