What science or psychology is behind the Landmark Forum's coursework? The Landmark Forum is a self-help seminar focusing on helping individuals to make positive changes in their lives by chaing their point of view and using logic to break down emotions to change the way one feels.

According to Wikipedia, the Landmark Forum is based on est, the Erhard Seminars Training, which itself is based on the Socratic Method. However, is there any science or actual psychology behind the Landmark Forum?
This isn't a direct answer to your question .

I got the sense that Landmark was in the same category as other so called 'power' therapies such as neurolinguistuc programming etc. The 7:30 report - a credible Australian current affairs program - did an story on Landmark last year.
