Documents uncovered about our fine governments efforts to use mental powers that on the surface were ridiculed. Of course, no secret why they made fun of such things, because they had more potential than they wanted people to know. An entertainment intro to this would be the movie Men Who Stared at Goats. I can only imagine the other powers or inventions that we are capable of, but are not allowed to surface because of the potential to unseat power. Could be they spent a bunch of money and never had success.
