>My opinion is that amyloid-as-cause moved from a majority to a minority view over the past few years, but it's not yet reflected in the literature
>I don't have a "read" on the evidence, because I don't read Alz literature
these two sentences seem contradictory to me. i am not sure how you would keep up on the research (to know it's moved from majority-held to minority-held view), and know that the move is not reflected in the literature, without reading the literature.
Most scientists who are not experts in their field don't read the literature for a field directly. Instead, they synthesize their opinions about the field by consulting experts, and weighing various sorts of evidence. In my case, I work in an adjacent field and see presentations from scientists, have casual conversations with them, and read the news articles in major journals.
The raw literature for alzheimer's, as well as biomed in general, is not really easily interpretable. It's rife with errors, misleading statements, and intentional obfuscation.
