Fun! I played this without sound, and got all of them correct.
I think part of the problem is that I knew that some videos were fake, so I was looking to see if their lips matched other movements. If somebody is talking fast, but their body language/movements are far slower than their talking, then it’s a pretty obvious tell.
If I had just seen one of these videos out in the wild, I can’t say if I’d immediately notice they’re fake, since that wouldn’t be the first thing on my mind. I think it’s probably impossible to get an accurate test given this limitation, but this test would be good for more casual people to try (i.e., people outside of HN).
