I am no expert on this topic, so can only speak from my own experience having taken MB twice, 7 years apart, scoring INTP on both occasions. Each time following the test I read a few pages in the book about INTP as well as a few pages on each of the archetypes on which I was judged not to be. Generally I regard personality tests with enormous skepticism but in the case of MB I must confess I was impressed with how accurate the INTP profile described my world view. More importantly, I found no such positive correlation between how my mind works and the other profile descriptions.

If the test is worthless, as the author of this article suggests, how would he explain people like me who upon reading the profile for their archetype in the book attest "yes that is a shockingly accurate description of me" and upon reading others' profiles react "no absolutely nothing about that resonates with me"? My own view is that MB, while hardly perfect, is surprisingly revealing for many individuals and can help one understand and be more tolerant of people whose profiles are in sharp contrast to one's own.

That said, I have taken other personality tests which highly intelligent people have recommended to me and found absolutely no value in those results. But I would not make the claim that those other tests are therefore universally useless, because after all I am but one data point.
