"Roberts knew the experimental science that let him interpret what he was seeing, in terms of deep factors that actually did exist."
As these the same kinds of deep factors that show that watching talking heads on TV in the morning will cure insomnia because "Anthropological research suggests that early humans had lots of face-to-face contact every morning "? - Roberts' solution for insomnia as described in NYT: http://www.nytimes.com/2005/09/11/magazine/11FREAK.html
So you have a theory personally developed and promoted by an enthusiastic individual, a whole slew of positival anecdotal evidence, but no actual proper experimental verification. Sound much like - ooh any complementary or alternative medical treatment you'd care to mention? Are you sure you're being fully rational here?
ok, but it's still merely a 'just-so' story with no worthwhile evidence behind it.
