There have been studies that show group social dynamics can spread (like behavioral viruses), e.g. the behavior traits that lead to obesity do in fact spread due to the conforming nature of humans.

Timescales are, of course, orders of magnitude different, and maybe that is the only difference that “matters”. E.g. we would still rearrange chairs on a slowly sinking titanic because that’s what humans do.
