I got 17 out of 20. yay. I can nearly always pick a fake smile. But its more to do with the persons energy, expressed through their eyes. Theres no gleam of happiness when its faked.
wow that was interesting.. i got a 10 out of 20, and i thought i was good at spotting fake smiles... or maybe it's fake politeness/demeanor... i work in food service so i get a lot of that.
14/20 So much for looking for other things, such as the length of the smile, and whether the person's mouth looked "used" to smiling.... Still, not bad?
