3. Personality Tests

Tests like the MMPI and other question and answer type tests ask people to answer questions about what they think is true of themselves or what they are consciously aware of.

Other psychologists felt that so much of our personality was controlled by unconscious things.  Projective tests are used to try to get at one's unconscious thoughts and feelings. In these types of tests a client is shown various images  and asked to freely respond with whatever comes to their mind. 

One of these tests is the well known  Rorschach Inkblot Test.  It was developed by the Swiss psychiatrist Hermann Rorschach (1884–1922). The Rorschach Inkblot Test is a projective measure of personality in which the respondent indicates his or her thoughts about a series of ten symmetrical inkblots.

Although you can find these inkblots and the supposed meanings of your responses on the internet and in books, these types of tests were always meant to be administered by a psychologist.
