I hate being typecast.

Woody Allen caught my sentiment best in a quote from his film Annie Hall: “I love being reduced to a cultural stereotype,” which of course means the exact opposite.

However, most of us enjoy playing games and sorting our friends into different personality pigeonholes. She’s an ogre, he’s a coward, she’s warmhearted, and so on. It is even more enjoyable when the person being typecast is someone like John Kerry or George Bush.

All would be well were it not for a fact that so many people take personality typing too dead seriously, and use it to determine future careers, marriages, and even potential travel destinations. Indeed some 15 million people are tested on the Minnesota Multiphasic Personality Inventory (MMPI) each year in the USA alone. Furthermore, 89 companies in the Fortune 100 use the Myers-Briggs Type Indicator (MBTI) to ascertain which job applicants would be most suitable for employment.

With such profligate use (or misuse) of personality assessments, it is not surprising that these tests are coming under intense fire. Abraham Lincoln (1809-1865) once said, “You can fool some of the people all of the time, and all of the people some of the time, but you cannot fool all of the people all of the time.”

Are personality tests the genuine article with some basic integrity, albeit flawed? Or are they one grand hoax fooling millions of unsuspecting suckers worldwide, worse than any corporate scam ever perpetrated?

Let us look at the criticisms leveled against these tests. One such attack is made by Walter Mischel (1956- ). He found that the results of personality tests, such as the MBTI, are not consistent. Up to 47% of testers end up with a different personality type when retested. He argued that if there is reasonable stability in personality traits, then the wild fluctuations in typing must be due to a flawed test.

Defenders of the MBTI test claim that people with more emotional personality traits, like aggression, are naturally prone to considerable fluctuations, depending upon the circumstances. There is nothing wrong with the test. Indeed it is great that it is sensitive enough to reflect a person’s changes in personality. After all, we behave differently when we are at school, in our office, in a party, with our parents, or at home, don’t we? The problem is not in the test, but that people get bored with repeated tests, that they become rather capricious with such tests, and some may even sabotage them. Conscious and unconscious factors which can affect the expression of different aspects of personality, especially during testing, are not taken into account with these studies.

The second attack leveled against personality testing is that personality is like a huge metaphorical elephant. We do not fully understand the nature of the beast. And the current state of the art in testing is still in its infancy. Thus each test conducted is rather like a blind person feeling a different part of this proboscidean. People are too readily labeled as “individualist” or “challenger” or ESFJ or INTP, or something else. But we do not really know what the labels mean. Nor can we or should we use the labels to predict future behavior. Until we gain a much better understanding of personality, it would be too presumptious to use these tests to determine someone’s entire future livelihood or marriage. I think this is a fair statement.

A further problem is referred to as The Barnum Effect. The term is used in psychology to describe the tendency for people to be rather gullible, and accept vague descriptions of themselves as accurate. This is best seen in astrology, graphology (handwriting analysis), palm reading, psychometric tests, as well as personality profiles. It is named after PT Barnum, a circus showman in the 19th century who had the talent of making others believe whatever he said, whether true or not. The problem with personality profiles is that people are placed into broad categories that overlap considerably. Most of us will fit into several of these pigeon holes. As there are no independent means of assessing the veracity of personality tests, reliance upon one’s own assessment is fraught with hazards of mistyping, due in part to an inherent self-deception.

Hippocrates (460-377 BC) suggested that human personality consisted of the blending of four humors or temperaments, namely sanguine (courage), phlegmatic (unemotional), choleric (bad-tempered), and melancholic (despondent). This roughly corresponds with the four characters in Frank Baum’s (1856-1919) Wizard of Oz: the lion who lacked courage, the tinman who was unemotional, Dorothy who was upset because she had lost her way home, and the scarecrow who was sad that he thought he was witless and worthless.

Modern day theory has not moved very much further. Today we talk about the Five-Factor Model, which comprises the following personality traits: openness, conscientiousness, extraversion, agreeableness, and neuroticism.

Personality testing will always remain popular because we are thirsting to know the answer to such questions as “Who am I?” “What am I good at doing?” “With whom will I get along best?”

I hate being typecast because I do not consider myself a one-dimensional person. Perhaps it’s true that I have multiple personalities. I mold my personality to match the person I’m with at that moment of time. As for career advice, I certainly do not wish to be told that the best job for me is to become a garbage collector. Not that I have anything against this profession. Better that than to be a starving author! But still, I like to be given the freedom to make my own mistakes, thank you.

In the final analysis, until there is better validation of their results, personality tests should remain in the domain of party games, and not be used for any serious and less-than-trivial pursuits. Their interpretations must be taken with a ton of salt!

    No. None of the criticisms you levelled at the old personality schemes are applicable with the Big Five. For instance, test-retest reliability is closer to 90% than 47%, but a more important consideration is that the Five Factor Model has discarded the entire notion of type. Big Five research describes traits as being widely distributed, rather than bimodal; in other words, there is no “visionary” or “architect” type, merely a distribution of traits.

    The Big Five traits also have proven quite useful in making predictions. For instance, Conscientiousness shows decent correlations with independent job performance ratings, while Neuroticism (particularly of the wife) is a predictor of future divorce. Predictors are useful; to demand that they be perfect is unreasonable.

    In fact, it strikes me as probable that what you’re really complaining about is fools who take personality inventories farther than they can go – personality explains a lot, and self report inventories are pretty good at measuring personality, but they aren’t anywhere near perfect and can’t tell you everything. What you really ought to be complaining about is how gullible most people are – although it might be better to try to find a solution than merely complain. Check the URL; you’ll see what I mean.

    I believe that current personality tests are very accurate. However, I also agree that they are being taken to seriously, to the point, as you said people assume that “she’s a challenger” or “he’s an individualist”. Other factors influence how you act; Character for one, who/what you associate with is another. If you you are a MBTI type that, for example, “lives for justice”, but you have bad character, then you will be completely different from the same type with strong character. Or, if you’re an INTP(“thinker” or “architect”) and you fill your mind with junk, your thought patterns will be negative and you will be completely different than a positive thinking INTP. Those are just some of the other indicators of who you are. Personality has its place, but a person is more like a house on pillars; each pillar has an equal role in the houses’ efficacy.
