Objective Personality Tests
Assessment methods that use a restricted response format (ordinal scale ratings or true/false questions), and which contain extensively tested validity scales to determine whether the person taking the test is responding truthfully. The Minnesota Multiphasic Personality Inventory (MMPI) is a well-known objective personality test.
