PBS in Arizona featured a doctor who offered some form of high tech brain scan. PBS was not selling the services of the doctor directly, but in order to promote the fund raising effort they sure touted the diagnostic and clinical capabilities of this guy.
I did a quick check on the internet and found that at least one site listed him as bordering on fraudulent. Their complaint was that his claims of the efficacy of his diagnostic procedures was not based on standard clinical procedures; i.e., no use of blind studies. Instead, he relied on conjectural data. They said that the type of scan he used was not demonstrated to provide the information that he claimed. For instance, he claimed to be able to diagnose early Alzheimer’s.
From reading the review and listening to him, I concluded that he probably believed in his methods and they might be legitimate, but he certainly could have deluded himself.
Meanwhile, PBS hacks stand up in front of the phone banks giving him legitimacy while asking for money and bragging that they are somehow more “pure” than broadcast TV since they are not beholden to “evil” [not said, but certainly implied] corporate sponsors.
