Rorschach developed his test in 1921 using hundreds of random ink blots of various shapes and colors which he showed to 300 mental patients and 100 normal control subjects, recording their interpretations. He finally settled on the best ten which showed the greatest consistency in responses from the control group and variability among the mental subjects.
Rorschach originally intended his test to diagnose schizophrenia, but its applications have grown for a variety of diagnostic indicators. Each card looks for specific responses from the subject, and different cultures see different things. Accurate interpretation by an analyst can take years of clinical experience.
