Status: Psychology test
I've linked to a fake smile test before
, but this one
hosted by the BBC (and designed by Professor Paul Ekman, from the University of California) is more elaborate since it allows you to see actual video clips of people smiling. I did quite badly at differentiating the real from the fake, scoring only 9 out of 20. The blurb at the conclusion of the test notes that "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."
That made me feel a bit better. The blurb also explains that "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."
However, I don't think knowing that will significantly improve anyone's score on the test.
