There’s an old joke about the psychologist who shows a patient an ink blog and asks him what he sees. “That’s a man and a woman having sex,” the man replied. He shows him a second inkblot. “That’s two men and a woman having sex,” he said. And a third inkblot. “That’s a man and two women having sex.” The psychologist says, “I think I know what your problem is; you’re clearly obsessed with sex.” “Me?” the man says, “You’re the one showing all the dirty pictures.”
Dr. Mike Drayton has an article on the BBC website about the origins and validity of the Rorschach test and points out that how a psychologist reads the test may say as much about them as it does about their client:
Criticisms of the Rorschach have centred on three things:
First, some psychologists have argued that the testing psychologist also projects his or her unconscious world on to the inkblots when interpreting responses.
For example, if the person being tested sees a bra, a male psychologist might classify this as a sexual response, whereas a female psychologist may classify it as clothing.
This seems rather obvious now that it’s been pointed out, doesn’t it?
