>>11187572You have to know the right people unfortunately. For example with the Area 51 thing, I heard from several reliable sources (back when I was in grad school) that they moved the juicy stuff to Wyoming a decade ago.
Regarding NLP, hypnosis, psychics and those kinds of things, they actually dedicated a good amount of resources to studying them and officially "they didn't find anything noteworthy". Guess you have to take their word for it.
For the regular guy, your best bet is to have an inquisitive mind and read a lot of top-quality research on the subject.
