The Skeptic's Dictionary has quite a good post on Landmark. It's trying to be fair and balanced.
While it discusses the advantages and disadvantages of the Forum and other courses, and the money they cost, it leaves one area very grey.
The effects of Landmark are often described by acolytes as immediate and profound. That's probably so for those susceptible to this kind of persuasion. What we hardly ever hear about is the long term effects.
Does Landmark's Forum have any long term effects--either positive or negative? Are the only ways to get longer term effects by taking more and more expensive courses?
Of course Landmark itself has never researched this nor will it. The evidence would probably be too ambiguous. Punters aren't going to pay money unless they have certainty.
