I definitely think there's something to what you're saying. I've heard people talk about how a large percentage of people form their beliefs purely on the basis of what they think is socially acceptable (as opposed to based on principles or arguments). This is one of the reasons why arguing with most people is so futile.

It's often safer to be wrong together than right alone.

For my part, I usually defer to others on these sorts of decisions, because I know I won't get upset if I don't get my way and that doesn't seem to be the case for people in general. I'd rather not get my way and still have a pleasant time, than get my way and have to deal with someone being a petulant child about it.
