@Tfmonkey About that experiment you referenced: If 75 percent agreed b matched, then there was more than 1 already saying c, right? 25 percent of 15 participants is more than 1 and if 1 person agreed with you c was correct then it dropped to 5 percent? I don't see how that works out with like the maths...
@UnpopularOpinion all except one of the participants was an actor. The actor conformed with the group 75% of the time when they all agreed on the wrong answer buy only 5% when one actor said the right answer.
