Study conformance theory.
What basically it says is that 1/3 of all people will believe whatever you tell them. E.g. religious / folks with false belief systems. The world is not flat. 1/3 of folks are complacent. They just go along, even with stupid ideas. They only differ in that they don't believe in crap from the former group. Finally, there's 1/3 of the folks who can engage in critical thinking, stand on their own, and live in the real world.
Conformance theory has been studied for years.
Many folks are insecure; especially some gay guys, and are always seeking validation through the pack. It's stupid, but, is what it is. Folks are truly idiots that are in that first group, but, they can't help it.
FYI: it's other's. Possessive, you know.
