Personality and Intelligence: A Brief Contrast and Comparison

Personality: The complex of all the attributes--behavioral, temperamental, emotional and mental--that characterize a unique individual; "their different reactions reflected their very different personalities"; "it is his nature to help others"

Intelligence: The ability to comprehend; to understand and profit from experience.


Many people have been conditioned to think that one of the above can be changed while the other is concrete for life. The ability to comprehend and apply lessons to one’s experiences to their benefit and the benefit of others is something that is not constant: This is a reason why intelligence quotient tests can be used as a metric of change in intelligence. Given a specific demographic the knowledge, skills, and the ability to apply them to a series of problems is charted across peers in that demographic. As we grow older we may learn more or we may learn less, but at any rate maturity tends to bring with it increased judiciousness and a changing attitude towards risk.

By contrast, personality is the underlying construct to intelligence: Just like an operating system controls the functions of a computer or the framework of a house determines how large the house can be or where walls, rooms, and doors can go, personality instructs how we learn and how our intellect interacts with the rest of the world. Just as new information can change our intelligence if we are receptive to it—just as it is that a house can have an addition added or rooms taken away—what is to say that personality, the underlying construct of who we are, cannot be just as malleable?

Research by developmental psychologist Dr. Carol Dweck at Stanford University suggests that this is, in fact, the case. An article recently published in Newsweek overviews the old way of thinking and the empirical data that suggests otherwise:

The old thinking was that our personality—the sum total of our human qualities—was an inherited legacy, fixed at birth and unchanging through life. So we had adventurous people and timid people; competitive Type As and laid-back Type Bs; conscientious, truthful types and—well, scoundrels and liars.

Instead:

The new thinking is that these traits are not fixed but in flux, and there are many ideas about why personality might change. Dweck's theory is that our beliefs about ourselves and the world—our "self theories," in the jargon—are a powerful influence on who we become in life. In other words, our own lay theories about personality and aptitude actually shape our character.

Years ago when I was in a special leadership development course we were taught that “People see the world how they want to see it.” This correlates strongly with the adage that “someone convinced against their will is of the same opinion still.” My friend Rick once counseled me with the following advice: Whenever we have problems with someone it behooves us to look inside. It stands to reason, then, that the best way to change our world and how we interact with it is to look inside and change our worldview.

In Dr. Dweck’s research hundreds of pre-teens were given a standard IQ test. Most of them scored “OK” on the test but different groups were praised differently on the test: Some were praised for their natural talent (“What a great score! You're so smart!”), while others were praised for their hard work (“What a great score! You must have worked very hard!”). The first message was crafted to convey people’s abilities as a fixed personal asset and the second message meant to convey a person’s abilities as something that can be changed.

As they say, “the proof is in the pudding:” Where results are the things that matter, the children who were told that they were smart were less apt to expose themselves to more circumstances that would possibly offer evidence to themselves that would take away this worldview, this perception, that they had. The pre-teens that were told that they had worked hard, however, were more apt to expose themselves to new challenges more because it allowed them the opportunity for growth.

To prove the point, the pre-teens were subsequently given very difficult problems to solve. When they failed, the children that were told that they were “so smart” saw it as a blow to their self-worth. Those that were told that they had worked “very hard” just “dug in more.

The story gets better.

After all the testing Dr. Dweck gave the kids the opportunity write down their thoughts about the test, leaving a space to record their grade on the test under the auspices that it would be for those that took the test in the future. Those that scored badly inflated their test scores in order to improve their own self-perception of their own self-worth. In other words they justified their actions by lying to themselves in order to make themselves feel better instead of expending the effort to actually do better.

In the end the research has proven that undesirable personality traits need not be permanent or be allowed to affect our lives for the worse: As long as we don’t allow our self-perceptions to be negative and look at problems as opportunities, exerting enough good old-fashioned effort, each of us should be able to overcome anything in our path.
