I got the first 5 wrong because I thought I was meant to pick the computer, not the real person. After that I did ~20, got them all correct.

There's alot of tells. Glasses make the edge of the eyes look strange. Around the ears, hats, sometimes the backgrounds etc, the blurs are wrong or corrupt.

However, if I didnt know 1 of the 2 were generated, I wouldn't look for anything and would probably just assume it's real, unless there was real obvious corruption on the face.
