On This Day in Science History - November 8 - Rorschach Ink Blots

What do you see in this picture?
Tests show most people will say "A bat". Looks more like a fox face to me. Supposedly, there is no wrong answer.
November 8^th is Hermann Rorschach's birthday. Rorschach used this inkblot and nine other inkblots to aid with his psychiatric practice. The Rorschach Test was intended to give insight to the workings of the patient's thought processes. While the test is still popular, controversy exists among psychologists as to whether or not the test actually shows anything at all.
