This reminded me a of a TED talk I saw recently: https://www.youtube.com/watch?v=H_pqhMO3ZSY https://www.youtube.com/watch?v=H_pqhMO3ZSY It's only 15mins long but you can skip to 2:35 for one of the face experiments and to 8:00 for an experiment they're running now. That latter experiment is quite creepy but I'd love to know the results.
