In this list, we detail the 25 most popular personality tests in the world, from the ever-iconic Rorschach inkblot test to the lesser-known but commonly given Minnesota Multiphasic Personality Inventory. To properly take these tests and get a valid result, you’ll have to pay, but feel free to look for reduced versions of them online; just know they likely won’t be entirely valid. If you’re interested to learn more about yourself (and the personality tests which will help you do that), check out this list of 25 Different Personality Tests To Help You Discover Yourself. NB: It should be known many of these tests are seriously challenged by psychologists. While nearly all have been developed by the profession, many people raise alarms about the tests’ validity and reliability. Rather than go in depth about all the criticisms, we’ve chosen to focus on the tests themselves.
