Phsychology as a concept? That is rather a wide group of fields. No doubt some have their uses. I happen to think Freudian phsychology is laghable though,
yes peer pressure is phychological. No argument there.
I went back and tried your link again. It was kind of interesting but somewhat misleading in that it all but said that I was wrong and should try again. It didn't even cross my mind that it was possible to make the same choice a second time.
IMO this wasn't an issue of peer pressure. I could care less what most people choose. I was simply under the impression that I was not
able to pick the same choice again and was physically being forced to choose a different one. Since I was 100% sure I was right, I chose to say to hell with it and left the site. That was why it pissed me off.
