The above is mostly from Johnstone. Previously on LW. (ETA: not textually from the Status chapter in Johnstone's Impro, but quite clearly cribbed from it. The whole list needs a garland of "citation needed" annotations - none of these assertions have any evidential backing AFAICT.)
I can't remember how I found this, just that I was amazed at how rational and near-mode it is on a topic where most of the information one usually encounters is hopelessly far.
