I took the hated Myers-Briggs personality inventory today. I had never taken it before, so perhaps my hatred was misdirected. But the very idea of classifying people along four binary attributes seems prima facie ridiculous. 16 total personality types in the entire world?
So all right, I’ll now grant that it has some more value. The main value seems to be that it helps you figure out careers that would be a good fit for your personality, which you might not have known otherwise. It’s also good to help you know which managerial style — micromanaging versus letting you create your own path — is right for you. And if it helps you toward that goal, then great; I have no problem with it. Inasmuch as it’s useful, I support it.
However, I encountered a lot of problems with the “instrument” today, and noticed something at the end that could have short-circuited the whole process. First, the inventory asks a bunch of questions of the form “Tell us which of the following words is more appealing to you, based on what it means rather than how it sounds or looks.” One such pair of words was, for instance, “kindhearted” versus “hard-headed.” I don’t see how this could be a valuable question to ask someone, or at least ask me. Depending on the time of day, I might answer that question completely differently. Today when I answered these questions, I was thinking a lot about people I know: would I prefer to be friends with a hard-headed person, or a kindhearted person? Surely a kindhearted person. On another day, I might have had difficulties with someone over a project that didn’t move ahead quickly enough, and I consequently might have more positive associations with the phrase “hard-headed.” It depends.
A lot of the questions play out the same problem: depending on context, I might answer one way or another. This translates into difficulties in the final four-letter analysis of the person taking the test: if you had to describe yourself as either Extraverted (E) or Introverted (I), which would you use? For me, it depends; there are days when I don’t want to see anyone, so I turn off my phone, hide in my room and read a book. Other days I want to be with my friends. In a job setting, I’d prefer to work with a team of people, but every now and then I find something at which I’m much better than my coworkers; when that happens, I want to go off and do it on my own. So am I an E or an I?
At the end of the test, they give you a few personality profiles that seem to match what you answered. It turns out that the personality profile I thought I was (INTJ) is different than what the test says I am (ENTP). Looking at the descriptions of both side by side, ENTP does seem the better fit. But then . . . why didn’t they just give me sixteen descriptions of the various personality types and ask me to choose? Why go through a large set of questions? I’m sure there are good reasons, but it all seems bassackwards somehow.
I also messed up the test. It works by giving you a bunch of more-or-less redundant questions, probably as a statistical check on the others. Presumably a lot of the seemingly redundant questions are slight perturbations of the others, just to see how resilient your responses are to little changes in the questions. Fair enough. But along most of the four dichotomies, my answers were just barely over the line into the personality type assigned to me; like I said, on a different day I could have gone another way.
There must be better ways to measure personality than this. I’m just deeply skeptical of this test, more so after having taken it.
