Why a High IQ Doesn't Mean You're Smart

D1gital_Prob3 writes "How can a 'smart' person act foolishly? Keith Stanovich, professor of human development and applied psychology at the University of Toronto, Canada, has grappled with this apparent incongruity for 15 years. He says it applies to more people than you might think. To Stanovich, however, there is nothing incongruous about it. IQ tests are very good at measuring certain mental faculties, he says, including logic, abstract reasoning, learning ability and working-memory capacity — how much information you can hold in mind."

  6. IQ is not the same as EQ by Aceticon · · Score: 4, Insightful

    IQ measures raw mental abilities. It's a bit like measuring raw CPU power and memory in a computer.

    EQ (Emotional Quotient) measures things like self-motivation abilities (including things like optimism), self-control and inter-personal abilities. They're a bit like measuring the quality of the software that runs in a computer and how well it works together with other programs in the network.

    [Sorry, no car metaphors]

    In real life, even though a large IQ will allow you to solve incredibly complex problems, if you have a low EQ, you might actually be incapable of doing so because, for example:

    • Low self-motivation means you give up too easy unless constantly rewarded
    • Lack of self-control means you constantly get side-tracked with other "interesting things" not directly related to solving the main problem
    • Difficulty with relating with others means that you will either never be assigned the big problems to solve in the first place or will have trouble communicating the solution at the end. Also if the problem is not fully and clearly defined up-front (like the vast majority of real-world problems) you will have trouble with getting more information from others

    In the end, a high EQ is much more highly correlated with success than a high IQ.

    Simply put, being optimistic means you're more willing to take chances (which might eventually result in a big payout), being self-motivated means that you can keep going even when things are though, having self-control means you can deny yourself a small reward now for a much bigger one later and being good with people means you can more easily find the chances and convince others to work with you.

    That said, the good news is that one can change one's own EQ over one's life - most of its component are behavioral traits that can be learned.

The comment struck me as amazingly arrogant and short-sighted. I didn't say anything at the time, but I thought exactly what you are saying. This guy's problem, in my not-so-humble opinion, was that he was letting his score on an IQ test define himself and his potential friends. As long as people who score well on IQ tests go around wearing it like a badge and looking down on everybody else, they are going to be outcasts, because even if you don't say it out loud, people will pick up on it, and then they don't want to be around you. Nobody wants to hang out with the guy who's always subtly reminding everybody of how smart he is. At that point, it's the natural human reaction to soothe your ego by thinking "average people just can't handle being around smart people like me. They're jealous of my vast intelligence." But it's just not true. I have plenty of friends who would probably score lower than I would on an IQ test (I say "would" because the last time I took an IQ test I was around eight years old). I also have friends who would probably score higher. You can be friends with anybody as long as you're mutually willing to accept each other as equals. And when you do that, you find that there's something to learn from everybody. Because I guarantee that even the homeless guy you pass on the street who sleeps on a park bench and pees on himself knows something that you don't. He has acquired some skill, knowledge or wisdom from his life experience that you haven't. As long as we define ourselves and others strictly in terms of a single, nearly meaningless number, we close ourselves off from a wealth of potential knowledge and experience.

    It's not exactly a mystery. You tend to mimic the lifestyle of your parents, and they mimic the lifestyle of their parents and so on. So if your parents placed a high priority on schooling, learning, education etc then you are likely to pass that lifestyle onto your kids. So... you might have many generations which have been too busy putting food on the table with multiple jobs or dealing with gangs or drugs or a dangerous neighbourhood and had more things to worry about than making sure their child focuses on school, gets help with homework and stays out of trouble.

    And vice-versa. My parents were big on school so I was very limited in my TV/video game time. I had to read a novel each night for an hour and my homework was priority #1 after school. My sister struggled and they got her a tutor. As a result I did well in school and will pass that on to my kids.

    Of course, you can have within individual families a radical shift. One parent decides they want 'a better life' for their child and makes a big shift resulting in that family breaking the cycle. But when you are looking at entire societies or segments of the population that kind of change is much slower.

    Race or any other 'trait' has nothing at all to do with it other than historically. The "such and such race is inherently smarter than such and such other race" argument is nonsense, and horrendously hard to test because family and societal factors creep into your study if you are looking at a large enough study group (ie - student performance across a state or country).

Those Irish, Italians, and people growing up in Appalachia have a significant, definite chance, however small it may be, to work their way out of the ghetto. Black people in America largely do not, or if they do, it is obviously a significantly smaller chance than do other groups of people.

    The real question is, why after a generation of post civil rights marches and such, things haven't really changed? Why haven't more Black people not availed themselves to free education?

    We just elected a black man president.

    Change isn't some magical thing where suddenly, one day, everything is completely different. Most people do not even recognize change as it is happening, they recognize it after it has already occurred. For a very, very long time, blacks in America have lived in a country which was either outwardly hostile to them or completely unsympathetic to their situation.

    As you said, it's been about a generation "post civil rights and such". Eisenhower forced desegregation of schools in the South in the 50s; exactly what effect do you think that should have? Starting around 1960, blacks finally had an "equal" opportunity for education. I say "equal" because it still obviously isn't quite completely equal, even though it is no longer strict segregation. It's been about one generation, at most -- the people who could go to desegregated schools have grown into adults and have probably had children of their own.

    One adult got the opportunity to receive a good education, and with this opportunity comes the potential to take advantage of it or waste it, just like any other. The rates for wasting it are probably slightly higher still because of the quality of education they may receive, as well as coming from a background where it may not be highly stressed, or where it may be completely unaffordable. One pair of adults have one set of children, who receive a similar opportunity. There's still a lot of work to be done, both by the people who sometimes unknowingly support discrimination against blacks, who must recognize their faults and their communities' faults in prolonging the poverty of blacks, and even moreso by the blacks themselves, who must work hard as individuals in order to take advantage of the opportunities presented.

    One of the major problems is that the black subculture in America has been so shattered that it has no real ambition. There are very few role models. The role models they do have have often been forced into specific tracts of life. It should be obvious that the "success" achievable for a white man in America aren't as available to black men in America, for a variety of reasons. As such, the underclass tends to focus its skill, effort, and talents in other areas, especially ones which have an emphasis on individual abilities and personal distinction, in part to separate them from the negative stereotypes. Look at the histories of American music and writing in the 20th century, or at cultural phenomena, where many have a very profound impact from black people who managed to be successful and innovative. The blues, jazz, swing, and rock and roll all have very, very distinctive black roots. Blacks are commonly depicted as being better dancers or perhaps better singers. American literature abounds with black poets and writers, with a much greater proportion than could ever be expected normally. Look at sports, especially in the latter half of the 20th century and on to today, where black athletes have practically dominated. Why is this so?

    It's one of the few avenues of life where they are allowed to be successful, and everything in their lives is practically constructed to shift them into having a focus in those areas. Remember how I said they are often lacking in role models? Many of the role models they do have succeeded in areas like this. Kids all over dreamt of
