I would assume that’s precisely the point of this silly game — to demonstrate directly that you can’t accurately judge someone by their appearance. But maybe I misinterpret?
Sure, I can see that. It just triggered me a little bit that I was being encouraged to judge people so readily. Plus, the comments here didn't seem to make that connection. They mostly saw it as a particularly "hard" challenge, rather than an exposition of our own biases.
I'd assume many people here interpreted it as a test of general knowledge rather than a test of ability to divine someone's homicidal tendencies from their mugshot.
You're quite right. It's absolutely mocking that idea --however lightly in an entertaining way --which is better than the 'we know better lecture' alternative.
