(Sort of; you did say “more gossipy → more widely known”, but I wanted to specifically add the word “larger”, the point being that a small + extra gossipy community would have a higher that usual report rate, and so would a large + extra gossipy (+ memory-ful) community; but the larger one would have more raw numbers, so you’d get a wrong estimate of the proportional rate if you estimated the size of the relevant reference class using intuitions based on small gossip communities. And maybe even a less gossipy but larger network would still have this effect; like, I *never* hear gossip about people in communities I’m not a part of, even if I talk to some people from those communities, so there’s more structure than just the rate of gossip. It’s more a question of how large is the “gossip-percolation connected component”.)
