I cannot remember where I read thisa A study of human behavior was done I think in England. They asked a class room full of teenagers to always pick line B no matter what the question was they then called in a guy and asked him to join the class. The had 10 straight lines of different lengths drawn on the black board. Line A was the longest. They asked the class which line was the longest and the whole class put up their hand for line B except guy who was not told to answer only B. He looked around and you could see that he was uncomfortable but also put his hand up for line B. He later said that he knew the answer was A but did not want to be different.
I think most of us are like this, we all at some stage of our lives have conformed to other peoples norm just to fit it and not draw attention to ourselves. In a mind control group this is even more likely to happen and it does.
I'm ashamed at the way I treated friends that were df. Yes, I confromed to the norm of my surroundings at the time something I hope I have learnt from and will never do again.
