I imagine so. I first learned of the MB typing about 3 years ago and while I wouldnt say I learned anything about myself that I wasn't aware of, I was amazed at the accuracy and it probably made me more aware to recognize myself in print more than an astology chart had done. Apparently modern psychology frowns on it as pseudo science while it derives from Jung's work on archetypes. Apparently modern psychology prefers the "Big 5" test, which I also took and the results are similar except that pegged me as an extrovert which is not all that surprising as I'm a not shy introvert and each of the 4 letter designations in the MP testing are which pole in a spectrum are you closest to and I recall i'm toward the middle of the I/E spectrum.
