They have a VR simulation of swimming with dolphins. They let little kids try it. Then a few months later, they ask the kids about their experience of swimming with dolphins. A sizable fraction think it really happened, and add details as if it were real. It's possible to use VR to implant false memories.
They have the capability of mapping one face onto the video image of another person, and can construct, using morphing software, combinations of two faces. They've discovered that, if they construct a face which is weighted 1/3 or so of the subject's face and 2/3 of some politician's face, and play a campaign speech, people still recognize the politician but agree with them much more.
