This is so awesome. I had never heard of the experiment at the time I saw this video and it was a complete surprise for me at the end. I was assuming that since the research was done over 50 years ago, there was no ethics committee to tell him that what he was doing was unethical or immoral so everything was really happening. In the end though it turned out all right haha! Anyway this video below is the extended full version (I saw a 10 minute cheesy version filled with humor on spikedhumor) so it’s more educational and stuff.
Learning about psychology has never been more fun! See the wiki article for more basic details.
