Elizabeth, there isn't a single psychometric test out there that doesn't give different results for the same person over a longer period of time. That is becausee people don't know themselves very well, and they change their minds about their own chracteristics.
Of course, being an INTJ, I don't do that, so I have tested INTJ for the past 40 years - at universities, at doctor's dealing in industrial psychology, and at job tests.
The real resistance with this test starts with sheer jealousy by all the other people who want to make as much money as the INTJ does. The other tests are not being used by Human Resources in business. Nor are they used at universities.
I'm well aware of the criticism. However, it is the only test that ever got me right. It has described me personally. Of course, I never lost a job because of it. In fact, the only business that ever tested me, offered me their job. I declined.
That said, I was given other tests, and one comes to mind by J C Pennys in the US. Apparently I tested to have a type A personality. Well, at some point during the job, I got highly the hell in and explained to the manager who tested me that the only reason I was working for $1100 per month was because I didn't want stress.
She then explained to me that I was a type A personality. I am not. Not even remotely.
However, the test asked me repeatedly if I was always top of the class, if I always excelled at everything, if I generally got As at school. Well, yes. That's becausee I'm gifted with an IQ that has been measured at between .001% of the human population or off-the-graph.
I didn't push myself for any of this. It just happens naturally. To achieve that, other people have to drive themselves. I don't.
Then there's the test given to me by a Dr. Schwart in San Diego. She asked me to do it twice because she found the tests very strange. The second time she told me the reason I was the way I was because I was a rebel, but the results were that I was very sensitive, and rebels weren't sensitive. But that's what the test indicated.
The test was wrong, of course. The writer of the test kept asking me if I would join in with the group, if I would go along with the group, etc. Well, of course, I wouldn't. Why on earth would I join in with a criminal group? We are taught very much to think fo rourselves in South Africa, and we do NOT go along with group activities when they are criminal.
I found out later that groups, in the USA, were social groups. The test did not specify social groups. It just said groups. In South Africa, the Group Area Act, and the word 'Group' was extensively used in a negative way.
I would love to know why MBTI is used at most colleges and unviersities for career guided purposes or why Human Resources uses it. All of these people learnt about the test in those same psychology course, and, of course, all these things are open to criticism.
The last comment made me laugh. It misses neuroticism?
For more than 40 years, I trotted to psychologists and psychiatrists trying to find out what was wrong with me - that's on three continents. In all that time, not one of them picked up that I had Asperger's Syndrome. In fact, many of them told me that I had taught them a lot. Well, I suppose when one has read some 600 psychology and self-help books, that would happen. After all, they read fewer than a 100 for the degree that they study.
I've covered all of this in two articles. Link below. What is more interesting is why you chose to tell me this. Did you lose a job through MBTI?
