Some of it is in my deck that Linda included on the original post on this thread.
This seems like a very good theory. It makes sense. Google uses the majority of the 200+ ranking factors to establish a primary sorting of the SERPs, then lets the UX signals sort the rest.My theory is Google sees that all the "predictive" measures of page quality are strong and so the algorithm bumps that page up higher than it might otherwise to test user interaction (CTR/etc).
