I will say, um, I was going to say in my thoughts on this question, time, uh, was, was a really big kind of a current change that a l- that we, uh, are able to grapple with now because we have access to data.

So that just re- reinforces what Ron said.

There are two things I'd, I'd add to this actually.

That one is that Lynn Freeman's book on the history of the field of social network analysis is a wonderful, wonderful kind of historical document that, that goes back hundreds of years, actually.

Picks up some, uh, studies that were done a long time ago that were flavors and gave us some kind of a bedrock of information that, that we've been building on ever since.

But, uh, certainly, I think provides a nice frame for exactly the kinds of phases that Ron talked about.

Mm.
