In my post Bomb Threats And You: Temperaments In Action, I wrote about the four personality temperaments. The temperaments are now part of the modern Myers-Briggs Type Indicator, but they date back to at least 590 B.C.

Akemi Gaines at Real Life Spirituality left a comment on that post, bringing up a number of points I wanted to respond to. Now a year and three months later, I figure it’s about time I did! All quotes are from Akemi’s comment.

“All these personality analysis are based on the respondents’ answers, in other words, their own perception of their preferences and choices. This automatically sets limits…is my own observation correct?”

The MBTI and most personality profilers are based on the individual’s self-assessment. And while that makes perfect sense in some ways, it also makes it easy to intentionally or unintentionally bias the results. If you want to be a certain type, or you think you know the “right” answer, or you wish a particular trait applied to you, it’s easy to be less than honest with yourself (possibly subconsciously).

Last month I wrote about a career test based on color preferences. While I wasn’t much of a fan of that test, I like how it’s hard to influence. If you like green, and you have no idea whether that’s “good” or “bad,” you might as well say you like green.

But if the person is capable of steering the results towards what they want, I think we just have to accept that as a limitation of the testing methodology. The best defense is to be careful to answer the questions accurately, knowing that there are no right or wrong answers.

“For instance, if I choose going out with friends rather than staying home as my preferred way of spending spare time, wouldn’t I know already I’m extroverted? Do I need the test to tell me?”

Probably not. Most people already know whether they’re an introvert or an extravert, because these are terms they’ve been hearing for years. However, it’s very unlikely that they really understand what they mean, particularly introverts (hence, the need for The Introverts Strike Back and Introverts And Extraverts: Can’t We Just Get Along?).

Also, there are people who are somewhat borderline, who might need a test to tell them what they are. There have been many I vs. E debates over Hillary Clinton, Barack Obama, Oprah Winfrey, and Adolf Hitler, for example.

Finally, while the average person may already know whether they’re an introvert or extravert, they don’t know a thing about sensing/intuition, thinking/feeling, or judging/perceiving.

“In reality, I spend the majority of my time alone at home, and my answer may be based on my perception of what I do in my spare time — those occasional special time I go out. So am I really E?”

When someone came to my workplace to administer the MBTI, she went over the types of our company’s two founders. She surprised some people by telling us that our extremely chatty CTO was an I. She explained that although he talked a lot, you have to pay attention to what he was talking about – generally software, never himself.

In the same way, there are surely explanations for an extravert who spends most of their time alone at home, but let’s not put Akemi under the microscope.

“Another problem of these analysis is they force us to think in either-or way. For instance, MBTI puts you either sensing or intuitive. But really? This may be helpful for someone who is close to 100% of either way (I’m 100% intuitive. I hardly see the “practical” side of reality) but what if someone is, say, 60% intuitive and 40% sensing?”

I think this is one of the most valid criticisms of the MBTI. If you think of the S-N scale as a continuum from 0% N to 100% N, it follows a normal distribution, or a bell-shaped curve. A few people are close to 0% N, a few people are close to 100% N, but most people are clustered around 50% N. So then why are we polarizing everyone, when most people are near the middle?

I don’t have a good explanation, but the theory is that your absolute position on the scale matters less than the side of the middle on which you lie. Meaning that a 45% N might be more similar to a 20% N (far, but same side of the middle) than they are to a 55% N (close, but on the other side).

This doesn’t make much sense, but it actually seems to hold up pretty well. I’m not an extreme T and I’m probably only a moderate N, but I definitely connect with these sides far more than their opposites.

“In this case [60% intuitive and 40% sensing], I think it would be more helpful to say, “You are very intuitive and conceptual, but you are also very capable in paying attention to details””

Yes, people should be aware of different sides of their personality. If a detailed customized report is available, it should explain this. If only general descriptions of each type are available, the person should read about similar types. And if they can take the MBTI step 2, this breaks down each letter pair into 5 facets, to show their preferences in much more detail.

“In my case, judgmental and perceptive is almost the same amount. If you check ENFJ, you may agree it’s Akemi.” [She identified herself as an ENFP]

Yes, I can see that. ENFJ’s are “the great communicators.” I’m very split on J/P too, and if you check INTJ (“the masterminds”), you may agree that it’s me [but I'm really an INTP]. (BTW, be careful to use the words judging and perceiving rather than judgmental and perceptive – many people use them interchangeably, but they have different meanings.)

Being split on a letter does happen sometimes. I spoke to a career coach who had a client that was split right down the middle on all four letters – and very confused about what career path to follow!
