Social Psychology: It's not that difficult to change a group member's attitude

Who knew? There are experiments from the 1930s onward testing the will of people when faced with a rigged experiment or placed in groups. Terms such as groupthink appeared. This was difficult material for me to accept, as I have lived the past 50 years in a culture I was not born into. I have resisted conforming in a quiet way. In work type of situations I did in fact become part of the group. My training lumped me with my kind against "engineers" and "business types" to achieve results in my field of science. It was also useful in job interviews. Every job I got was due to a link to the interviewer, we were equals. However, with things like politics and religion, I never made any waves in a group of strangers. Just get on with what we were doing and don't bring it up. I never had to change my attitude for a group. In any test of psychology I would be the outlier.

As it happens, this one area of  behavior where the right and left are equally susceptible to group pressure. You might be a libertarian, hang out with liberals and appreciate personal freedoms. Then global warming comes up. You have not had the time to read the books to find out 1) is it warming? and 2) what are the predictions? Those are separate problems, you realize. You went to college. But it has become dogma in your group. So you just accept that. The election comes up and you do not make any complaints against a political candidate that places climate high on the agenda. Although sexual minorities and freedoms as well as your suspicious attitude to "big government" may be more strongly part of your thinking. And the cute girl in the group is a liberal. You start tolerating climate change as a big topic, as well as the health and exercise attitude you share. You and your partner are building a better planet with healthier people.

The field is social psychology. It is possible to look at the individuals, it is even possible to use neurobiology and other experiments. But still, it is an empirical field. You can measure the activity of groups with polls and tests of groups in lab settings. You measure trends. This causes that. You don't entirely know why. Conformity, response to strong leaders, obedience, all these things can be measured. As it turns out, rank in your gang also matters. It is easier to influence a low ranking member.

Want more? Try the Richardson book. Not the best book on the topic, but easy to read for the layman.  The rest of the classic books are rather dated. Wikipedia will go a long way with Milgram. See also the entry for the man there.
