Your Visual Skills Are Not Correlated To Your IQ (vanderbilt.edu)

Science_afficionado writes: Psychologists at Vanderbilt University have conducted the first study of individual variation in visual ability. They have discovered that there is a broad range of differences in people's capability for recognizing and remembering novel objects and this ability is not associated with individuals' general intelligence, or IQ.
Or, as the article puts it, "Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching."

    This is not new information. Millennials should be banned from science until they are at least 45. They 'discover' the already discovered with alarming regularity, and for some reason feel compelled to publish their 'findings'. Newsflash: science is not instagram. It'd be a freaking miracle if they read an old book or paper (formerly known as 'research') instead of conducting their endless science fair projects. Newsflash #2: refusing to acknowledge the work of others is not the same thing as independence, especially not independence of *thought*. If anything, it is the sheep mentality exemplified, and more important still, it doesn't work. Management, please reimburse the ten minutes I spent on this. Thank you.

    I take it then that you didn't like your score.

    IQ tests aren't meaningless, they're just not the solution to every question about intelligence. They're mainly useful in measuring things relevant to formal education before all the new changes.

    I have a high IQ and I can tell you that it's not meaningless, it's just not what people think it is. I can push far more data than anybody else I've met before going crosseyed and I can count cards with the best of them using my own system.

    As for visual skills the tests don't really focus on anything too intensive which is probably why there's so little correlation. I can't visualize at all, but I'm roughly 3 stdevs out.

    The most important thing to remember is that IQ tests are neither meaningless nor harbingers of all types of intelligence.

    There are several 'recognized' intelligences, and arguably many more.

    words (linguistic intelligence), numbers or logic (logical-mathematical intelligence), pictures (spatial intelligence), music (musical intelligence), self-reflection (intrapersonal intelligence), physical experience (bodily-kinesthetic intelligence), and social experience (interpersonal intelligence).

      The only reason we say this is that intelligence tests show that all the wrong kinds of people are intelligent. Thus the resort to "storytelling intelligence" and other nonsense. Intelligence is correlated with every kind of positive life outcome, while lack of intelligence is correlated with every kind of negative outcome. This unacceptable political outcome is why scientists say "heritability stops at the neck" bowing to the extreme social punishments for anyone who dares speak out.

      You're assuming there is some singular RPGesque attribute called Intelligence which governs every decision a person makes. Physically, that would manifest itself as something like more robust connections between brain neurons... I just pulled that out of my ass, but if there's a better explanation for the mechanism that governs singular intelligence, I'd love to hear it.

      The other view is that "intelligence" refers to aptitude for a particular task. To me, that model more accurately describes what we see. You see people who pass calculus with honors, but they can't determine what to say to potential dates. You see people who can balance the books of their company, but they fail to grasp the basic principles (rules and physics) of driving. You see people who can design and build houses, but they can't give you a geopolitical analysis of the wars in Afghanistan. Even when all these people have access to the same information.

      There is no doubt that a person's DNA can affect their aptitudes for these various tasks. But when you say there is some singular variable that raises or lowers all these aptitudes simultaneously, that seems like a coarse simplification. Ignoring the nuances does a disservice to your understanding.

    A developed, specific skill is not the same as general skills. Duh ! That is about like saying that a person who is a musical genius might not do well with foreign languages. There are all kinds of abilities and as the savants demonstrate one can be a super genius in one area and unable to walk to the corner store and return home without being totally lost. There are also some really challenging tests with the colored blocks that psychologists have used for decades. Being able to remember the colors and geometries of all six sides of a cubs and solve a complex puzzle quickly can be more strenuous than many test subjects can tolerate.

    Sure, but success is not the same thing as intelligence. And success is strongly correlated with wealth and access to good schooling (although there are plenty of exceptions), which suggests that IQ is not measuring some kind of innate ability or mental processing limit.

    Your lack of a background in science is showing again. Success is strongly correlated with wealth, and also strongly correlated with IQ. IOW, look up what "controlled study" means. For IQ, especially, it's easy to control for socioeconomic effects, hence the "IQ is strongly correlated with success" assertion.

    You keep saying IQ is correlated with various things... But not intelligence.

    That's what I started with - "IQ is strongly correlated with success".

    IQ tests don't measure "intelligence" because that word, for many people, depends on context. IQ tests measure problem solving ability. This is probably why it correlates so strongly to success: a strong ability to solve problems probably results in a large measure of success anyway.

    IQ tests are like BMI - mostly accurate, for most of the population, in the ways that actually matter. If I were to bet on a random high-IQ person successfully performing an unfamiliar task while you bet on the low-IQ person successfully performing an unfamiliar task, after a few iterations you'd lose your money and I would not.

    IQ is a great indicator of a person's problem-solving abilities. Many people do not consider problem-solving ability to be 'intelligence'.

    So what are you claiming it actually measures?

    Within 20 points of the mean (80 to 120), IQ scores are strongly correlated with income and financial success. Outside that range, the correlation breaks down. If you have an IQ of 140, you are unlikely to earn much more than someone with an IQ of 120. Likewise, someone with an IQ of 60 won't earn much less than someone with an IQ of 80.

    IQ is strongly and negatively correlated with incarceration. People in prison tend to be dumb. This could mean that dumb people commit more crimes, or that they are more likely to get caught and be convicted. Mostly likely it is a bit of both.

    IQ is not correlated with happiness.
