It's Gwern! He's like a combine harvester for data in all forms, digesting it and putting stuff out there that is usually bullet proof and extremely enlightening. I've yet to see him put out something that didn't meet that standard. Well worth your time, also on other subjects.
The actual linked PDF is not from Gwern, it's a 2003 paper from two sociologists Blake E. Ashforth and Vikas Anand.
