New IQ Research Shows Why Smarter People Make Better Decisions (phys.org) 141

alternative_right shares a report from Phys.Org: A new study from the University of Bath's School of Management has found that individuals with a higher IQ make more realistic predictions, which supports better decision-making and can lead to improved life outcomes. The research, published in the Journal of Personality and Social Psychology, shows that people with a low IQ (the lowest 2.5% of the population) make forecasting errors that are more than twice as inaccurate as those made by people with a high IQ (the top 2.5% of the population).

The research used data from a nationally representative sample of people over 50 in England (English Longitudinal Study of Aging ELSA), assessing their ability to predict their own life expectancy. Individuals were asked to predict their probability of living to certain ages, and these estimates were compared with the probabilities taken from Office for National Statistics life tables (a demographic tool used to analyze death rates and calculate life expectancies at various ages). The study controlled for differences in lifestyle, health, and genetic longevity.

By analyzing participants' scores on a variety of cognitive tests, as well as genetic markers linked to intelligence and educational success, Chris Dawson, Professor of Economics and Behavioral Science at the University of Bath, showed that smarter individuals tend to have more accurate beliefs about uncertain future events - they are more skilled at assessing probability. Individuals with a higher IQ are significantly better at forecasting, making fewer errors (both positive and negative) and showing more consistent judgment compared to those with a lower IQ.

    Maybe Altman and others are right: we are just pattern (token) prediction modelers.

    Whatever we call "thinking", "consciousness", "mind", "intelligence", "sentience", (and I don't want to descend into supernatural/magical thinking words here like "soul") are just not well defined words from an era bygone, where we didn't even know what we had inside our heads, we were not aware of the existence of neurons etc. Those words are just very rough definitions (aka bad prediction models) for what was going on inside our heads.

    Maybe we are just prediction machines at times (system2) and parrots (system1/LLMs) most of the time.

      I agree that humans mimic LLMs with respect to probability judgements. Marketers know that if you see a "fact" written in a few different articles or sources, you come to assume it's true, for example. We rely on what our culture feeds us and we internalise it as beliefs.

      But the other words you mentioned are actually very difficult and deep questions which smart people throughout the ages have wrestled with and we still don't know the answers today. Sentience/the ability to have an experience is the most obvious and direct reality we each have, yet nobody knows how that works.

      Yes our minds can remember things we've heard and repeat them like a photocopier or an LLM, but we don't know what is experiencing the whole show.

          If you study philosophy, we do have multiple good definitions of cognition, it just modern science tends to ignore these as not being sufficiently objective and "theoretical". If you are curious, John Vervaeke [johnvervaeke.com] has a series of lectures on YT where he goes over basics.

          What was empirically shown by LLM is that reasoning and cognition is not purely "associative engine" by producing machines that are vastly superior to humans in being able to associate and yet vastly incapable of reasoning and knowing.

              As a Philosopher... yeah I agree. In fact, I think it was Quine who suggested that if you wanted to know how the mind works you should study Psychology instead (I'm paraphrasing).

              > multiple good definitions

              that by itself shows they are not actually good. If there are many, it means they are not precise/accurate and the right ones.

              Well, maybe. I don't think it's necessarily fair to say that because we have multiple competing definitions, which can really be thought of as multiple competing theories in a scientific sense, that they are not actually good ("good" is another one of those super loaded words so what is "good" to you might not be "good" to me, unless we further clarify what the standards are). We are not in possession of all of the data as far as the human brain goes, so our definitions must be based on incomplete information. I think if you spent the time studying Epistemology you'd find the working definitions used there actually are pretty good, well thought out, internally consistent, etc. (not saying this is worth your time though). As they say, don't make perfect the enemy of good.

              > incapable of reasoning and knowing

              those two words "reasoning" and "knowing" are two more vague terms, for which we don't have good definitions still, what exactly they mean. They belong in the same set of words in my original comment

              Words are... weird. To say we don't know what they mean is a bit off, because there is not necessarily any need for a word to be more than a fuzzy box around a concept that we employ in our day to day lives. Some people think that words spring up from the concepts or objects which they describe, as though there was some Platonic form of that thing which the word must truly apply to; I find this strange and too metaphysical for my tastes. As I see it, words are invented by humans to describe something we see/experience; they end up being as vague as our understanding, but they still serve their primary purpose, which is to communicate our lived experience of the world with another human. The idea of knowing something, or the idea of reasoning, they are not foreign to us: we understand what someone says when they say "I know that person" or "I reasoned that this would happen based [evidence, causal links, etc.]" even without pre-agreeing on what the definition is.

              When we then set about crafting our technical definitions for use in Philosophy or Science is the only point at which we start to run into this trouble that we're talking about. Partly, I think, because we are trying to use a word to put a box around a process that we do not possess all of the data on (knowledge/reasoning). You will likely agree when I suggest that the solution to the problem is further scientific/empirical study; but, I don't think it's necessary to say that absent a complete and perfect definition we shouldn't use the best ones that we have available to us at the moment.

              This is very low bar, because neuroscientists have no understanding how the mind works, but they do have some understanding how the brain physiology functions. These are not the same. We are very far away from coherent Hegelian proof of how the mind works, if anything LLM's notable lack of ability to know and reason is a proof to the contrary.

              To demonstrate the point - we are communicating abstract ideas formed by our subjective experiences from which both of us (hopefully) derive some meaning. However, h

            In grad school, the one thing I noticed about the top tier students was a basic humility. They were never embarrassed to admit if they did not know something or if they were wrong. In fact, they were excited when they were presented with something they did not know because it was an opportunity for learning. That is real intelligence and IQ tests do not test for it.

            The burning desire to correct someone when they are wrong has nothing to do with intelligence. Children do that to assert dominance over one another. It is an emotional response that has nothing to do with intellect.

        Bottomline: IQ is overrated.

        I would argue that it is merely poorly understood and reacted to at face value only. No depth to the perceptions.

        Yeah, that's the thing. Nobody has all the right answers, because nobody can ask the right questions every time. Nobody knows everything, and there's always that one thing you didn't think of that, when someone points it out, makes you rethink everything.

        The difference between smart people and not-smart people is that smart people probably point out those things to others more often than the other way around. :-)

        IQ is simply ability to handle complexity. It has no bearing on what to apply the ability to and what to use it for. I call that meta-ability "wisdom" and observe that most people do not have any.

      It is not, but IQ != ability to reason and know. That would be wisdom. Colloquially, many very smart people are not wise and you don't have to be smart (but it helps) to become wise.

    • This. I regularly recruit PhDs and Engineers in my company. Many I get to know well, and despite their intellectual capabilities, far too many of them have made some of the absolute worst financial and personal decisions in their lives, and too often even in work they are myopically focused on viewing a problem through their own intellectual training that they miss very simple solutions. A few are well organized, but I am consistently stunned at the poor decision making of highly educated people.

      People often confuse IQ with intelligence, but at the same time, will give more credit than is due to those with a lower level of intelligence because "they know that they don't know a lot". Knowledge vs. Wisdom. And yes, there are some very STUPID people who test well, but the initial confusion is what this "article" is based on. IQ research linked to those with higher intelligence is going to cause reactions like yours. Remember, the stupid people are the reason why fascist dictators and wannabe d

    • But remember not every high(er)-IQ person is smart. In fact a majority probably is not. Many chose to use their skills very selectively and are wilfully ignorant on some questions.

      On the other hand, some people with lower IQ are smart, because they have a realistic evaluation of their own skills, know what they do not know and hence are able to get good insights, even if sometimes with help.

      It's like any other strength, having it and applying it are totally different things. Nobody uses all of their potential all of the time. It comes down to willpower and training. Like being able to paint well but never finishing a painting, being strong and not knowing how to fight or lacking endurance, being smart and buying crypto.. IQ tests are like pull-up competitions, it'll help you find strong people, not people that don't suck at everything.

    • That is not how high general intelligence works. If you take two persons, one with high general intelligence and one with average general intelligence, that have the same knowledge about something - the high IQ person will be better on drawing logical and reasonable conclusions about the situation than the average IQ person. The high IQ person will also learn new knowledge faster than the average IQ person, and with this new knowledge, the difference between the two regarding conclusions will widen.

  • You can make good decisions if you follow two simple steps: 1. Decide what you want. 2. Decide how to get it.

    In my complete worklife I've always run into too many people who were exceedingly bad at (1). Their first question was always "what should I do". Instead of asking and answering the real question "what do I want to achieve".

    In all our centuries of (alleged) human advancement, we actually needed to prove through "research" that dumb people are in fact dumb and make dumb decisions?

    Was the aptly named Darwin Award we literally invented for the bestest of dummy decisions, not enough proof? Did that need to become a fucking Olympic sport or something?

    We humans sure do have a way of validating our humanity. The irony of Skynet, has turned painfully obvious.

      I don't think this research qualifies as "no shit." I think it qualifies as very poorly done and potentially wrong. Or at least the summary makes it seem that way. They asked these individuals a prediction question that existing knowledge significantly helps with. Existing knowledge that many if not most well educated people will have and people with less education probably won't. I know what the average life expectancy is for someone in the US because I have read it. I know that your life expectancy is dif

    There is a theory that my ving from tropical to temperate climates drove IQ development. You have to plan ahead to gather extra food (or plant extra crops) in the Spring and summer, so as to have food throughout the coming Winter. That's longer term and more complex than what is required in the tropics.

      The more interesting research on this topic that I've read claimed smarter people make better decisions because they are better at deferring decisions. They are comfortable with the uncertainty because of their confidence in their abilities. There is always a tradeoff between making the decision later when you have more information and making it earlier so you have more time to plan your execution. If you need more time to plan execution, you need to make decisions earlier. And your decisions will suffer because of this.

        This is a good point; and there is more to it. Other studies I've read discussed what is best described as "background processing". When given a problem that required more than just a cursory thought, participants who were told to "sleep on it" were able to yield better solutions, even when they were told NOT to focus on the problem. Just parking it was enough; because once you are aware of the issue, your brain, wonderful tool that it is, can work through/analyze problems even without your consciousness being directed towards it. Ever since reading this I've always encourage friends/family who are debating a big life move to, once they have gathered the relevant facts, park it and sleep on it at least one night before coming to a decision.
      • I'd be interested to see how much of it is deferral and how much is adaptability. I know that I make decisions now based on what I know now, and frequently adjust or change them as new information becomes available. Sometimes the decision is to defer deciding completely until later when not enough information is available.
    • If that were true you'd see it in at least some other species, and you don't.

      Our survival didn't depend on beating the environment or our development would have stopped a long time ago. You don't need what we have to do that, look around at everything else that does it.

      The only thing that makes sense is we were competing with ourselves, or a more intelligent predator, which doesn't exist. Like a shit ton of humans were living together and had fuck-all else to worry about but outwitting each other to survive

    Setting the obviousness aspect of this aside, there are two things of particular note to me in this story.

    1. Predicting the probability of living to certain ages seems like an absolutely ridiculous test. There's no reliable way to assess the accuracy of their predictions. Comparing their answers to probabilities from established statistics seems more about the subject's education level than their intelligence or forecasting ability, unless their forecasting completely impossible life expediencies like 1,000 years. But, there were more tests as well, and this may just be a badly written article.

    2. I am absolutely astonished that there is only a 2X difference in forecasting accuracy between the bottom 2.5% and the top 2.5%. To me that's a very low amount of difference between the intelligence level of the very brightest and the mouth breathers. I feel that this relatively small difference is orders of magnitude smaller than my own anecdotal observations indicate.

    • 'What is my future' is a much more complex question and is made up of numerous (hundreds and thousands) of smaller decisions. That 2x multiplier goes geometric.
    • 1)There is a very reliable way to assess the accuracy. You wait for them to die. If the researchers did not do this then the study is flawed.
      2)The way you breathe has no effect on your IQ. But I am also surprised especially when you consider that about 2% of people have an IQ less than 70(top 2% have IQ greater than 130)

    predictions made by the bottom 2.5%, with predictions made by the top 2.5%? I think it was Sagan who speculated that the difference between the average person and say Gauss, Einstein, or Newton may be greater than that between the average person and chimps. so the study may have provided more insight if they instead didn't compare the extremes, but rather samples closer to the average.
  • 100 smartest people (top 1%) look at the high risk/high reward situations and realize their chances of success are low, so none take it.

    100 above average people look at the same high risk/high reward situation and say, "WOW, I GOT THIS!". 95% fail, but 5 of them make it.

    For this reason, most of the 1% wealthiest people are above average intelligence but not the smartest. I am talking people with an IQ above 115, but below 130.

    • Low IQ people making bad decisions impact themselves. High IQ people may make good decisions for themselves, but screw over many. Unfortunately we let psycho billionaires run every country and corporation. They are not just worthless, but are dangerous.

    People in the lowest 2.5% would generally be within the threshold of intellectual disability. That's getting into the level where, among other things, the U.S. Supreme Court has ruled such persons cannot be subject to the death penalty because they are not capable of understanding their own actions. I would certainly HOPE that those in the top 2.5% could make better forecasts of the future than persons who are intellectually disabled.

  • I guess they too were in the lower 2.5%.

  • Now that we know this, how can we use it to benefit people. There must be decision support systems that can be targetted to assist people with the more mundane future likelyhoods. For example to support decisions on borrowing money to buy a house or a car.
  • True is true

  • Individuals were asked to predict their probability of living to certain ages, and these estimates were compared with the probabilities taken from Office for National Statistics life tables (a demographic tool used to analyze death rates and calculate life expectancies at various ages). The study controlled for differences in lifestyle, health, and genetic longevity.

    people with a low IQ (the lowest 2.5% of the population) make forecasting errors that are more than twice as inaccurate as those made by people with a high IQ (the top 2.5% of the population).

    So you compare two groups of outliers at the extreme of your statistical IQ model to how well they predict their position in your life expectancy model. And you "control" for differences in health, lifestyle and genetic longevity. This is comparing the group of people with IQ's under 70 that includes all the people who are mentally disabled with the group with IQ's above 135 including every genius in the world. Why is anyone taking this seriously?

    • mental retards are not disabled!
      They mentally still function. Their cognition is impaired in various ways to various degrees.

      Visually disabled people are blind. Visually impaired people use glasses or can't drive, etc.
