Thirty years ago in California, a new crash course in group psychology emerged.
In huge hotel meeting rooms, charismatic motivators urged participants in their hundreds to get rid of the 'rackets' in their heads.
Fortunes were made, people were saved, and scandals ruined lives.
Three decades later, these forum meetings still go on in Britain, though their methods have been refined.In the first of a two part investigation, Jenni Mills travels to California to find the truth behind the sensational headlines about the Human Potential Movement.
Jenni Mills continues her investigation into mass group therapy organisations.
This week's focus is on the British end of the business, and attempts to answer why so many twenty-year-olds are signing up.
Jenni persists in her efforts to see for herself what happens at one of these forum meetings.
