Quote from: techfan on Sep 07, 2006, 03:24 PMFrom what I have read, techniques developed by Cleve Backster, such as ZCT (Zone Comparison Test), are still widely used in polygraphy. This is the same Cleve Backster who also used polygraphs to "prove" bio-communication with plants, in a widely criticised article entitled Primary Perception.
While I already had great doubts about the scientific validity of polygraphs, I was astonished to learn this information.
I am surprised his psuedo-scientific research (both with polygraphs and psychic plants) aren't prominently featured on this web site.
Why isn't this used to further attack the credibility of polygraphs?
