You should be so skeptical that you will need to read about all 240 writers discussed here

Why read all past posts on the 240 writers (and related subjects) I have discussed over the last seven years?

Why not limit yourself, let’s say, to reading Marjorie Taylor’s study of 50 anonymous writers

plus my posts on the 10-50 writers with whom you are most familiar, and associated subjects, selected from my name and subject indices?

Because, if you have an ordinary amount of skepticism, you will need to read about literally hundreds of diverse writers before you are convinced that 90% of fiction writers actually do have real multiple personality (the creative trait, not the clinical disorder), and you begin to realize that if this is true of 90% of fiction writers, it may also be true of up to 30% of the general public (which would be a new view of normal psychology).

I know that if I hadn't explored 240 diverse fiction writers, I would never have believed those conclusions.

Added March 22, 2021: What I mean is that, if, like most readers of this blog, I hadn't had clinical experience diagnosing and treating multiple personality, then I might need to read about hundreds of writers before believing it. The great obstacle for most readers of this blog is that they have never seen the indisputable condition themselves. The reason I added the subtitle to the blog about memory gaps is that that is the most likely key for a person to discover multiple personality. I know that I was shocked the first time I asked a puzzling person if they had memory gaps and they said yes. Then of course I had to ask questions about that, which led to meeting an alternate personality, which is what convinces you that this is something objective, and not just an interpretation.
