Pareidolia describes pattern-seeking behaviour in individuals. Is there a term for when organizations demonstrate collective pattern-seeking behaviours similar to pareidolia?

I'm not sure it's the same as institutional confirmation bias – that would be selectively interpreting information to support existing beliefs. Pareidolia is spontaneous pattern recognition. Perhaps there's a gap in organizational theory here for something like "institutional pareidolia"?

Not quite what you prob meant but this recent piece by Mary Harrington on the term egregore rhymes? Root meaning of “audience capture” as collective pattern-seeking behavior. Content warning: the first third or so tough to read, here’s the nut: 
“… Suppose egregores are sufficiently real to merit discussion. Are such entities agentic and sentient? I’ll save that for another post; it’s a question that makes sense within an idealist paradigm, but that statement on its own probably needs more explanation than space allows here. So I hope that ‘no, but also yes’ will suffice for now. The pull of audience capture, though, is real: believe me, I feel its pressure daily. And the power of a really big egregore is difficult to overstate….”

Thanks @jenna. I do follow Mary and enjoyed her book. I missed this post but think there's something to work on
