Second attempt. Yes, it is fascinating how we “think” we remember things, but we really don’t.
And of course, this little experiment: https://www.youtube.com/watch?v=vJG698U2Mvo
This version of that is kinda boring lol. I noticed the gorrilla easily.
If you know what is going there… then you will always notice the gorilla or unicorn or whatever. However, someone who has never seen this or the other videos of the same kind and has no clue about what is going on, might not.
I was in a philosophy seminar on perception and we were shown the gorilla video, and even knowing what to expect because the prof had talked about it at some length, nearly a third of us *still* missed the gorilla. I was one of the ones who saw it just fine, but I’m unusually good at multitasking.
Did you see the followup video? With the stage curtain in the background?
