Rorschach test

Projective (based on the subject's frank responses to stimuli) personality assessment technique in which a subject is shown 10 standard pictures of inkblots five black and white, three black and red, and two of a same color. The subject is asked to speak freely (in as many interpretations as he or she wants to make) the images and emotions evoked by each inkblot seen as a whole or in parts. Invented about 90 years ago by the Swiss psychiatrist Hermann Rorschach (1884-1922), it is still hugely popular despite lacking any credible evidence of its scientific validity testimony to power of the myth that psychological tests can reveal something about people what the people cannot figure out themselves.
