Dr. Spitzer was skeptical, but he decided to find out for himself if sexual orientation was changeable. He developed a 45-minute telephone interview which he personally admistered to all the subjects. Most had been referred to him by The National Association of Research and Therapy of Homosexuality [note: the anti-gay NARTH organization founded by Dr. Paul Cameron, who was expelled from the APA for substandard research practices] and by Exodus, a ministry for homosexual strugglers.Tell me, can you see any potential flaws in this research methodology???
