The MBTI is more useful than an astrological sign, and less useful than a 15 minute conversation with someone, if you want to understand their personality. That said I think it's a mostly harmless way of classifying people, unlike race, class, nationality, profession, etc.
This is so poorly thought out. I really don't get why some people can't seem to tell the difference between things like MBTIs and astrological signs/zodiacs/horoscopes in terms of their potential to classify people in a meaningful way... One is an arbitrary mapping of a person's date of birth to an set of traits and prophesies. The other is a brief summary of a person's personality/behavioral inclinations based on a…
When I talk about external validity, what I mean is that the MBTI does not predict how people actually behave. What it says about you, and what you actually are, do not line up often enough or non-trivially enough for it to be valuable. The problem is not variation over time - that's fine. The problem is that when someone gets a result, that result doesn't say what it claims to about them. It's similar to astrology b…
If say some person knows two people and that one tested as INTP and the other as ESFJ and this person doesn't know for a fact who had which test results. Are you really sure they won't have better than even odds at figuring out which is which based on their interactions with the people that don't involve asking for their MBTI test results? If so, based on what study?
It's clear I wouldn't be able to tell them apart based on their birthday (unless they were super young or something), but it's not at all clear that it's the case for MBTI.
The covariance of the Big 5 and MBTI is high. This means that if you give both inventories to the same population you can do a factor rotation of one onto the other with much of the variance being preserved. This has been demonstrated multiple times in the academic literature. I have never read an article against the MBTI that mentioned this, and that's because the people who write these articles do not understand st…
That's very interesting. I'm in psychology and I've never heard this. Do you have a source for that covariation? Thanks!
Earlier quoted context omitted.
Add to that "People receive different MBTI results even in the same week."
That proves what? If you want to argue that people's MBTI fluctuates too wildly to be meaningful, the proper question is whether there's any information gain from knowing a person's previous MBTI results for subsequent tests, not whether it is exactly the same. And the answer to that is yes. If you know I scored INTP on my last test, am I equally likely to score say ESFJ on a subsequent test as opposed to INTP or som…
Some more critique on the article.
1. The Myers Briggs test result does not need to be binary. There are variants of the tests that give you a score on each of its 4 axes (Introvert/Extrovert, Sensing/Intuitive, Feeling/Thinking, Judging/Perceptive). For example, see https://www.16personalities.com/free-personality-test
2. The test results do not always talk about positive qualities. For example, here is a discussion of strengths and weaknesses of the ISFJ personality. https://www.16personalities.com/isfj-strengths-and-weaknesse...
Finally, on the point of falsification, I would like to suggest the following test. Take a group of people and let them take the test. Now let the close friends of the test taker read all the personality type descriptions and chose one for the test taker. Find the correlation between the friends' choices and the test results. If the correlation is significant, then the test is meaningful. Otherwise not meaningful.

> I really don't get why some people can't seem to tell the difference between things like MBTIs and astrological signs/zodiacs/horoscopes Then let me try to help clarify. MBTI has no predictive power ("I'm an INTP, so... ?") and is not falsifiable. Those are the delineators between science and pseudoscience, so that's why I bucket it with astrology.
As an individual (INFJ) thoroughly interested in Myers-Briggs, I often see this discussion brought up. As a short rebuttal, I feel as though many of those who tout Myers-Briggs as a comprehensive personality test fail to understand what the Myers-Briggs attempts to identify. While the "value-add" is more subjective, I'm going to go ahead and say it's not as useless as this article claims. While I don't think anyone (…
What about considering other starting points and comparing the added value of them with MBTI? How differs "So, you are INFJ, let's talk about your personality" from "So, you are Captain America/Hobbit/Sith Lord, according to this online test. Let's talk about your personality"?
