Dr. Applewhite's lack of preparation is startling, as others have mentioned. It should be noted that, from what I've seen/heard in the recording, it appears all that she was hired to do was to review the material that the Society had already made public, which is essentially WT propaganda meant to convey the appropriately upstanding, empathetic, loving, etc. image that they so vigorously protect. As such, it is--and I think the Commission can see this--essentially worthless, as the material NOT made public is what matters. Elders are routinely told to destroy letters and other records, for example. Applewhite would not be given access to confidential files or even the Elders' manual (although I guess that is publicly available now).
Also, she's coming up short in academic rigor, as I cannot imagine any report worth its salt not identifying, for example, those religious organizations to which WT standards supposedly favorably compare and offering instead a wildly generalized statement like "worldwide religions" or whatever it was that her report said. It's interesting that she's pointing out her own errors while on the stand (and of course, the Commission is doing so as well!).
