BK Eakman has written a lot about the Delphi Technique:
“In group settings, the Delphi Technique is an unethical method of achieving consensus on controversial topics. It requires well-trained professionals, known as “facilitators” or “change agents,” who deliberately escalate tension among group members, pitting one faction against another to make a preordained viewpoint appear “sensible,” while making opposing views appear ridiculous.”

Is that akin to the new-age psycho-nonsense that was / is promoted by groups like LifeSpring?
