Why the Myers-Briggs check is completely meaningless
The Myers-Briggs Sort Indicator might be essentially the most extensively used persona check on the planet.
About 2 million people take it yearly, on the behest of company HR departments, faculties, and even authorities companies. The company that produces and markets the check makes around $20 million off it every year.
The one downside? The check is totally meaningless.
“There’s simply no proof behind it,” says Adam Grant, an organizational psychologist on the College of Pennsylvania who’s written about the shortcomings of the Myers-Briggs beforehand. “The traits measured by the check have nearly no predictive energy on how blissful you may be in a scenario, how you may carry out at your job, or how blissful you may be in your marriage.”
The check claims that primarily based on 93 questions, it will possibly group all of the folks of the world into 16 totally different discrete “varieties” — and in doing so, serve as “a robust framework for constructing higher relationships, driving constructive change, harnessing innovation, and attaining excellence.” Many of the devoted consider it primarily as a software for telling you your correct profession alternative.
However the check was developed within the Nineteen Forties primarily based on the completely untested theories of Carl Jung and is now completely disregarded by the psychology neighborhood. Even Jung warned that his persona “varieties” had been simply tough tendencies he’d noticed, quite than strict classifications. Several analyses have proven the check is completely ineffective at predicting folks’s success in numerous jobs, and that about half of the individuals who take it twice get totally different outcomes every time.
But you have most likely heard folks telling you that they are an ENFJ (extroverted intuitive feeling judging), an INTP (introverted intuitive considering perceiving), or one other one of many 16 varieties drawn from Jung’s work, and you could have even been given this check in knowledgeable setting. Here is an evidence of why these labels are so meaningless — and why no group within the twenty first century ought to depend on the check for something.
The Myers-Briggs rests on wholly unproven theories

In 1921, Jung revealed the e book Psychological Types. In it, he put forth a number of totally different fascinating, unsupported theories on how the human mind operates.
Amongst different issues, he defined that humans roughly fall into two main types: perceivers and judgers. The previous group could possibly be additional break up into individuals who favor sensing and others preferring intuiting, whereas the latter could possibly be break up into thinkers and feelers, for a complete of 4 varieties of folks. All 4 varieties, moreover, could possibly be divided primarily based on attitudes into introverts and extroverts. These classes, although, had been approximate: “Each particular person is an exception to the rule,” Jung wrote.
Even these tough classes, although, did not come out of managed experiments or knowledge. “This was earlier than psychology was an empirical science,” says Grant, the Penn psychologist. “Jung actually made these up primarily based on his personal experiences.” However Jung’s affect on the early area was monumental, and this concept of “varieties” specifically caught on.
Jung’s rules had been later tailored right into a check by Katherine Briggs and her daughter Isabel Briggs Myers, a pair of Individuals who had no formal training in psychology. To study the methods of test-making and statistical evaluation, Briggs labored with Edward Hay, an HR supervisor for a Philadelphia financial institution.
They started testing their “Sort Indicator” in 1942. It copied Jung’s varieties however barely altered the terminology, and modified it so that folks had been assigned one risk or the opposite in all 4 classes, primarily based on their solutions to a collection of two-choice questions.
Increase two (the variety of prospects in every class) to the fourth energy (the variety of classes) and also you get 16: the several types of folks there apparently are on the planet. Myers and Briggs gave titles to every of those varieties, just like the Govt, the Caregiver, the Scientist, and the Idealist.
The check has grown enormously in recognition over time — particularly because it was taken over by the corporate CPP in 1975 — however has modified little. It nonetheless assigns you a four-letter sort to characterize which end result you bought in every of the 4 classes:

The Myers-Briggs makes use of false, restricted binaries
With most traits, people fall on totally different factors alongside a spectrum. In case you ask folks whether or not they favor to suppose or really feel, or whether or not they favor to guage or understand, the bulk will inform you somewhat of each. Jung himself admitted as much, noting that the binaries had been helpful methods of fascinated with folks, however writing that “there is no such thing as a such factor as a pure extravert or a pure introvert. Such a person can be within the lunatic asylum.”
However the check is constructed totally across the foundation that individuals are all one or the opposite. It arrives on the conclusion by giving folks questions such as “You are inclined to sympathize with different folks” and providing them solely two blunt solutions: “sure” or “no.”
It would be one factor if there have been good empirical causes for these unusual binary decisions that do not appear to explain the fact we all know. However they arrive from the disregarded theories of an early-Twentieth-century thinker who believed in things like ESP and the collective unconscious.
Precise knowledge tells psychologists that these traits should not have a bimodal distribution. Monitoring a bunch of individuals’s interactions with others, as an illustration, exhibits that as Jung famous, there aren’t really pure extroverts and introverts, however largely individuals who fall someplace in between.
All 4 of the classes within the Myers-Briggs undergo from these sorts of issues, and psychologists say they are not an efficient manner of distinguishing between totally different persona varieties. “Contemporary social scientists are not often finding out issues like whether or not you make choices primarily based on emotions or rational calculus — as a result of all of us use each of those,” Grant says. “These classes all create dichotomies, however the traits on both finish are both impartial from one another, or typically even go hand in hand.” Even data from the Myers-Briggs test itself exhibits that most individuals are someplace within the center for anyone class, and simply find yourself being pigeonholed into one or the opposite.
For this reason some psychologists have shifted from speaking about persona traits to personality states — and why it is extraordinarily laborious to discover a actual psychologist wherever who makes use of the Myers-Briggs with sufferers.
There’s additionally one other associated downside with these restricted decisions: take a look at the chart above, and you will discover that phrases like “egocentric,” “lazy,” or “imply” do not seem wherever. It doesn’t matter what sort you are assigned, you get a flattering description of your self as a “thinker,” “performer,” or “nurturer.”
This is not a check designed to precisely categorize folks, however quite a check designed to make them really feel blissful after taking it. This is among the causes it is persevered for therefore a few years within the company world after being disregarded by psychologists.
The Myers-Briggs gives inconsistent, inaccurate outcomes

Theoretically, folks may nonetheless get worth out of the Myers-Briggs if it precisely indicated which finish of a spectrum they had been closest to for any given class.
However the issue with that concept is the truth that the check is notoriously inconsistent. Analysis has discovered that as many as 50 percent of people arrive at a distinct end result the second time they take a check, even when it is simply 5 weeks later.
That is as a result of the traits it goals to measure aren’t those which can be persistently totally different amongst folks. Most of us differ in these traits over time — relying on our temper once we take the check, as an illustration, we might or might not suppose that we sympathize with folks. However the check merely tells us whether or not we’re “considering” or “feeling” primarily based on how we answered a handful of binary questions, with no room in between.
One other indicator that the Myers-Briggs is inaccurate is that several totally different analyses have proven it is not significantly efficient at predicting folks’s success at totally different jobs.
If the check offers folks such inaccurate outcomes, why achieve this many nonetheless put inventory in it? One purpose is that the flattering, imprecise descriptions for lots of the varieties have big quantities of overlap — so many individuals might match into a number of of them.
That is known as the Forer effect, and is a method lengthy utilized by purveyors of astrology, fortune telling, and different kinds of pseudoscience to steer folks they’ve correct details about them.
The Myers-Briggs is essentially disregarded by psychologists
All for this reason psychologists — the individuals who give attention to understanding and analyzing human conduct — nearly utterly disregard the Myers-Briggs in modern analysis.
Seek for any distinguished psychology journal for evaluation of persona assessments, and you will find mentions of a number of totally different programs which were developed within the a long time for the reason that check was launched, however not the Myers-Briggs itself. Aside from a number of analyses discovering it to be flawed, just about no main psychology journals have revealed analysis on the check — nearly all of it is available in doubtful retailers like The Journal of Psychological Type, which had been particularly created for such a analysis.
CPP, the corporate that publishes the check, has three main psychologists on their board, however none of them have used it in any respect of their analysis. “It could be questioned by my tutorial colleagues,” Carl Thoresen, a Stanford psychologist and CPP board member, admitted to the Washington Post in 2012.
Aside from the introversion/extroversion side of the Myers-Briggs, the newer, empirically pushed assessments give attention to totally totally different classes. The five-factor model measures folks’s openness, conscientiousness, extroversion, agreeableness, and neuroticism — components that do differ extensively amongst folks, based on precise knowledge collected. And there is some proof that this scheme may have some predictive power in figuring out folks’s capability to achieve success at numerous jobs and in different conditions.
One factor it does not have: the advertising and marketing machine that surrounds the Myers-Briggs.
So what’s the Myers-Briggs helpful for?
The Myers-Briggs is beneficial for one factor: leisure. There’s completely nothing incorrect with taking the check as a enjoyable, fascinating exercise, like a BuzzFeed quiz.
However there’s something incorrect with CPP peddling the test as “dependable and legitimate, backed by ongoing international analysis and growth funding.” The corporate makes an estimated $20 million yearly, with the Myers-Briggs as its flagship product. Amongst different issues, it prices between $15 and $40 to every one who desires to take the check, and $1,700 to every one who desires to turn into an authorized check administrator.
Why would somebody pay this a lot to manage a flawed check? As a result of after getting that title, you possibly can promote your companies as a profession coach to each folks on the lookout for work and the 1000’s of main firms — corresponding to McKinsey & Co., Normal Motors, and a reported 89 of the Fortune 100 — that use the check to separate staff and potential hires into “varieties” and assign them applicable coaching applications and obligations. As soon as licensed, check directors turn into cheerleaders of the Myers-Briggs, guaranteeing that use of the outdated instrument is sustained.
If non-public firms need to throw their cash away on the Myers-Briggs, that is their prerogative. However about 200 federal agencies reportedly waste cash on the check too, together with the State Division and the CIA. The military in particular depends closely on the Myers-Briggs, and the EPA has given it to a few quarter of its 17,000 staff.
It is 2015. 1000’s {of professional} psychologists have evaluated the century-old Myers-Briggs, discovered it to be inaccurate and arbitrary, and devised higher programs for evaluating persona. Let’s cease utilizing this outdated check — which has about as a lot scientific validity as your astrological signal — and transfer on to one thing else.
Correction: This piece beforehand acknowledged that the army makes use of the Myers-Briggs for promotions specifically, quite than utilizing it as a common software.
