The MMPI is “the original” and most authoritative personality test (being as it has been “studied” the most extensively (ie. the results correlated to random things); it is also quite extensive). Unlike other personality tests where all the possibilites are generally positive, this one does a good job of spitting out problematic traits. This happens to make this test actually useful.
Normal: Yes / No / Mostly / Not so much
(pay for detailed report)
Of course most people would come out as Mostly.
