Further, your request is nearly tautological. The way that one gets to a big, statistically robust test of a hypothesis is via small stepping stones. E.g., this sort of self-experimentation. If you scoff at everybody doing something small and say, "you're probably wrong because there's no big evidence", you decrease the chances of getting the sort of proof that you claim to want.
I don't think there's anything wrong with saying, "personally, I'd like to see convincing measures of the effect of bright light therapy on mood and intelligence before I adopt this." But that's frustratingly different than your apparent attitude that in 2 minutes of thought you know more about this guy's experience than he does.
