"It was an innocent time, the mid-1950s. America wasn't yet cynical about its geopolitical games in the Cold War. Case in point: In order to maintain its spying edge over the Russkies, the CIA considered the benefits of hypnosis."

Wow they are confidant in there hypnotizing ability. It makes me they were full of it or if there is alot the government doesn't tell us. The thing said they had nominal success with drug induced hypnosis that sounds a little scary. If drugs can bypass certain cognitive principles like memory, perhaps they could be used to put someone in that state of hypnosis and then bring them out of it. If that is possible the CIA isnt going to tell us. From what I have read on hypnosis and meditation they are powerful techniques that can have effects both mentally and physically causing the body to change arousal level, heart rate and such. It's hard to do research on material that is so insubstantial but what there is is pretty interesting
