What I observe with the majority of people: they are fully capable of being free-thinking individuals, but the main way they use this capability is to follow the crowd.
With herd animals that are prey creatures (i.e. cattle, sheep) this makes sense in terms of survival. There is safety in numbers. Stray from the herd, and you get targeted by ever-present predators.
With humans, who are at the top of the food chain and generally have no natural predators, it's just a form of cowardice. I'm not sure the DNA of fruit flies is going to provide a satisfying explanation here, at least not one that can be extrapolated to include people, fascinating though it may be.
