Other than the utter excoriation and brutal purge of thr Halloween Massacre, which was the dismissal of the majority of the CIA's HUMINT capacity you mean?
Tje guys behind MKULTRA were all fired. The entire approach that it came from was purged. Iran Contra was the clusterfuck it was because the guys that used to do that stuff were either forced into retirement by Carter or captured/killed by Hezbolah.
And MKULTRA was still drugs, not ESP.
Jon Ronson has an entire book on the CIA's experiments in psychokinesis and ESP. It's every bit as laughable as you would expect a Jon Ronson book to be. It also details how it was basically three guys on their own time in secret with zero official cover.
