Spot the Fake

[Shiny]

I got the guy with the long, black hair and crazy long teeth wrong because I was distracted by his odd hairline and crazy long teeth. And a few other people I just failed on. 16/20

I think that was a woman...albeit a very odd looking one.

13/20. I tried paying attention to how their mouths looked after the smile.

The idea being:

Genuine went from to

Fake went from to

Now I know I should have went with another method. I chose both middle options for the pre-test questions, but I don't know if the answers to those effect anything.

I'm one of those people who quickly stop smiling. Even if it's a genuine smile I go from default face very quickly because my cheeks get easily tired. I got 18/20 and was looking at the crows feet and the squint of their eyes.
