That’s fair enough, but even in that case I wouldn’t call it a “hivemind”. I can only speak from my own perspective (don’t have stats to support this) but I don’t think people click an arrow just because X amount of people have done the same. At least I don’t. What it seems like to me is, right or wrong, people will generally behave in ways that reflect their knowledge and level of interest in the subject.
That’s not a hivemind or herd behavior or whatever else people like to call it. The masses aren’t an NPC that does stuff on auto pilot.
