As a communication coach, to smile is one piece of advice for improving people skills I can never give enough of. At the same time, once in a while, some people express concerns about it not being real and appearing fake. Although I’m a big believer in authenticity, I think when it comes to smiling, real or fake, the advice is still fundamentally solid.

Here’s one reason why. Let’s start with a test I bet you’ll find interesting. It’s a “spot the fake smile” test and it’s based on the research of psychologist Paul Ekman, a pioneer in the study of emotions and facial expressions.  You can find it here, on the BBC website. Don’t just keep on reading; take the test.

OK. Did you take the test? How many of the 20 smiles did you identify correctly as being real or fake? The first time I took the test, I got 13 out of 20, which is just a bit more than if I would have picked the answers randomly.

The good news (for me) is that I’m no exception. Most people get similar scores at spotting the fake smile. According to psychologists who researched this area, people in general are pretty bad at spotting a fake smile from a real one. You’ll find out more details about this at the end of the test.

Smiling typically reflects friendliness and a positive state; it’s a great way for social bonding. There are particular ways you can go wrong with smiling and come off as weird, but you can learn about them and calibrate yourself at the context to improve your people skills. The general rule remains: real, fake, smile damn it!
