Don’t know if you’d consider remote viewing to be “psychic powers” or not, but there most certainly was a very serious effort to harness this form of anomalous cognition, termed “nonphysical perception,” for military purposes. Whether there still is, I can’t say.
It’s one of those fleeting, vague, out-of -the corner-of your-eye sort of things, for most people, but most people have at least limited ability to perceive nonphysically. There’s testing for it online, or once was. I played around with an online remote viewing test myself, years ago, through the Rhine Institute here in NC, http://www.rhine.org.
Got fairly good at it, too. Pretty simple. A blank, red screen, with a timer. You click on the area of the screen where you think the hidden dot is, and there are numerous screens in series, seems like twenty in all. I got pretty good at it, was in the top ten for the few weeks that it held my interest. My “trick” was to not focus directly at the screen, and when something twitched or darkened or flickered in an area of the red screen, I clicked on it. Focusing too hard blows it.
Wish I still had that link, I’d post it; but I don’t.
Skeptics proved that the original protocols allowed leaking of information which allowed evaluators to link descriptions and targets with greater than chance success. Once the protocols were tightened up, the effect disappeared.
Besides (AFAIK) this "psychic" stuff was never tested (or used) by the military directly. The remote viewing experiments were done by contractors, particularly a psychical research lab called The Stanford Research Institute (SRI). The government -- belatedly, IMHO -- killed this research in 1995.
