What is the Rorschach test?
This diagnostic tool was initially intended to provide insight into the mental processes involved with what was broadly termed schizophrenia. Rorschach, who died soon after completing his research paper Psychodiagnostik (1921) had cautioned that ‘that the test is primarily an aid to clinical diagnosis’.
From the 1940s, the Rorschach was adapted for use in occupational assessment and other areas of social science.
In contemporary English, the term Rorschach Test is often used metaphorically to describe what psychologists call projective assessment. Put simply, how you see something depends on your 'priors' or pre-existing assumptions.
