You Can't Get Smarter, But You Can Slow How Fast You Get Dumber (nytimes.com)

An anonymous reader writes: An article at the NY Times summarizes the state of research on cognitive improvement. There are multiple industries — from big pharma to the makers of "brain-training" games — trying to convince you there are ways to become more intelligent. Unfortunately, scientific research doesn't really bear that out. There is, however, evidence you can provide short-term boosts, slow aging-related cognitive decline, and trick yourself into achieving better outcomes. Experiments show that simply telling a group of low-performing students that intelligence is malleable led to higher test scores. Researchers also found a use for mental exercises, but only in adults over the age of 60, a time at which some level of cognitive decline is common. Physical exercise seems to help fight that cognitive shrinkage as well. Oddly, different exercises fight it in different ways. As for drugs, there is some evidence that stimulants help with long-term memory, but that's about it. That's not to say they have no effect, just that their effect is more to make you feel smarter instead of actually being smarter. The article does point out one of the best ways to combat cognitive decline: maintain social engagement as you get older. "[P]eople with the highest level of social integration had less than half the decline in their cognitive function of the least socially active subjects."

  1. Of course you can get more intelligent. by Anonymous Coward · · Score: 5, Insightful

    Study up on a new subject. Learn the material. Practice to acquire the skill. *poof* you are more intelligent.

    The statement might have been about the intelligence quotient, which (according to the theory) does not change over time. But it is also not a measure of intelligence. Nor was it ever intended to be. It is a measurement of intelligence potential.

    A person with a very high IQ but no education or opportunity can spend his entire life wallowing in ignorance (and probably poverty). A person with a boring average IQ who applies himself can master many difficult subjects and skills, and accomplish great things by doing so.

    Don't get too hung up on definitions of "intelligence," as they are numerous and vague.

      No you aren't. Intelligence is not knowledge.

      Yes but there is currently quite a political push for a natural aristocracy, which with my British heritage reminds me of Thatcher's speech in 1983ish where she talked about how she wanted a return to Victorian values - ostensibly about hard work getting you Up There, but in practice about everyone deserving and maintaining their place, no matter how opulent or squalid.

      So you have an awful lot of studies which try to tell you that some tests determine your rightful position in life, when in fact such tests are about likelihood that someone measured only by that test will perform to certain standards. It hopefully doesn't take more than a high school understanding of statistics to understand why even regarding this as a measure of potential is going too far - and to select people based on such tests is irrational.

      I have an IQ in the 140s, and certain larger firms take this way more seriously than they should, as I'm going to royally fuck up certain tasks that some of my colleagues with lower IQs can perform from competently to excellently. I will probably be quite good at quickly identifying how I'm being measured performance-wise, though, and I'll be great at Playing The Game for career advance. Similarly, I did really well at school and university, but I hardly cared for or understood in much depth any of the material beyond what I saw as required for homework and exams.

      I was great at cramming, and forgetting everything within a month. I am almost ashamed at my professional (engineering) qualifications, because - while they're not relevant to my current field, tf - when I achieved them, I knew there is no way I should ever be given the responsibility they imply I am ready for. If you want anything actually deliverable, you will need to put me in a wider team of more disparate talents, and keep me only on the things I excel at. In fact, people like me are probably more trouble than I'm worth - or at least this was true before I stopped thinking I was hot shit and understood that we've set up so many of our modern educational and professional structures around very limited metrics, creating a positive feedback loop which promotes an increasingly narrow range of abilities.

      So, I have a fairly high if not astronomical IQ, I'm actually talented at certain specific things but fairly crap at most things (and hopeless at a lot of "obvious" things), and people like me are useful but by no means necessary - if someone else takes twice as long to do certain things I can do, but also doesn't fuck up on so much else, they're a more valuable contributor to the advancement of humanity. IQ is a test of speed, and the world makes itself increasingly a test of speed - yet speed does not solve very big problems.

      My poor brother is genius level IQ, yet can't really function in life at all - he's gripped with anxiety and shame and low self-confidence... self-confidence is in fact listed in the article as a significant factor in achievement. If you tell people they can do better, they're likely to do better - but if you tell people that for some reason their biology prevents them from improving, they won't improve. Is this like the placebo effect for intelligence? I know if I'm panicking about solving some problem and become convinced that I'll fail then my short term memory seems to disappear and I miss obvious patterns in favour of making some ridiculously complex set of connections.

      From the article, I take positive lessons:
      - Brain training exercises won't help your IQ, but that doesn't matter at all - even if they simply make you feel more confident, you will do better from day to day because of placebo effect. If they help you with specific skills such as mental arithmetic or memorisation techniques, even better.
      - Performance-enhancing drugs might be similarly placebo.
      - Physical exercise is once again shown to benefit mental acuity.
      - Socialisation is either correlated with or causes slower decline.

      Intelligence is not knowledge.

      Intelligence is the ability to formulate an effective initial response to a novel situation. Having a large database (ie: knowlege) of other problems and solutions, is a big part of that, because you can often adapt the solution to a similar problem, to the current situation. Intelligence is the application of knowledge.

  2. Smarter ? by randalware · · Score: 5, Insightful

    Smart is to keep trying and learning from your mistakes & failures.
    anyone can be smart.

    Wisdom is hard.
    When to say no, when to say yes, and when to say "I love you" :)

    This is my opinion based on what little I know and understand of the rumors and lies Thanks, Randal
