No, I'm afraid the Tavistock Institute is one subject I know little about, just that there are allegations that they are/were heavily involved in mind control, brainwashing, social control, etc. research, and have seen a few examples in some video or another of the sort of stuff they allegedly put out - lots of flowy colors and soothing music designed to relax and confuse a person while presenting the message you want them to believe - especially if it is seemingly wrapped in something they might normally think is reasonable.

I've seen some interesting content on this site (can't say I would accept any of it at face value), so their entry on the matter might be interesting to review: http://educate-yourself.org/nwo/nwotavistockbestkeptsecret.shtml
