You said the camp promoting the amyloid hypothesis has struggled greatly to come up with evidence to support its position. What did you mean by that if not a read of the quality of the evidence?

Why do you continue to frame this as a choice between a single cherry-picked expert's opinion, and my own non-expert opinion? Either fairly represent the spectrum of experts' views, or decide based on the actual evidence and arguments.

My estimate of the quality of the evidence is based on daily discussions with people who work in that field and reading summary articles in major journals. I typically don't read raw scientific articles directly- those are aimed at people in the field. Instead, my understanding comes from a synthesis of expert opinions weighted by my own priors (based on 30+ years in the field). Derek's opinion is now the prevailing one that I hear from a wide range of researchers.

I've seen this happen before, btw- overturning establishment paradigms, especially ones where the underlying etiology is complex- is extremely hard and often takes decades of experimental results.
