I was pretty surprised when i took this test and only got 60% right ): I really thought I was pretty good in finding out if someone is being genuine or not. o well variance.
I tried to look for indicators of the smiles being forced and got plenty of them wrong.

Is anyone else easily fooled by the fake smiles in this test?
