Did you notice that some of the genuine ones made you unconsciously smile back?

17 out of 20 - most of my judgement came from the post-smile-recovery though.

I got 17 out of 20. Amusingly, I got all the fake smiles right, but I didn't trust some of the genuine folk.

Who me? Skeptical?

11 out of 20.

I looked at the eyes, but that didn't work out for me!

16 and i used the teeth.

My sick mind came up with so many questions that that could be the answer to... :evil:

18 out of 20... and I second guessed myself on the two I got wrong.. silly me.

17.

I wonder how they got them to smile genuinely for the camera.

16 out of 20, and I'm an eye man.

Statistically equal to guessing. After reading the "hints" 18 of 20.

Plus I would just like to add, #13 is very scary looking. :eek:

I also wonder if this type of reseach has a practical application like being able to tell if a woman is faking it...
