> the book is generally forbidden to be discussed in > "polite" company The problem with studies like this - and also ones that for example attempt to show race-linked differences in "positive factors" - is that they're pretty useless for anything other than the uneducated using as a blunt discrimination tool. Let's say you live in a society where there are blue and green people. A study shows a genetic basis for a difference - on average across the whole population - where blue people are 10% less intelligent and 10% more violent. What's next? Are you justified in preferring to hire green people? No. Are you justified in having greens-only policies? Of course not, that's not how averages work. Is there any basis for any kind of segregation? Any basis for any color-based policies? No. But you can be sure that there will be green people trying to use these studies to show themselves as superior, as a basis for discrimination, for popularist politics, and all the other associated bullshit. It's precisely because there's almost no practical use for studies like these, but they are absolutely pounced upon by racists and opportunists, that they're 'generally forbidden to be discussed in "polite" company'.

Ignoring reality is the worst possible option. Regarding your assertion, judging an individual by their collective group average is wrong. I'm a big proponent of research in this area - because I want to change it. For e.g. Black Americans have an IQ, on average, 15 points lower than white Americans. I want more research on this area, so it can be improved. Calling people racists (without evidence) shuts down any meaningful conversation, and hurts those who need the most help.

  > I want more research on this area, so it can be > improved Somehow it sounds more obviously ridiculous when you rephrase it and start looking for "solutions" to improving the intelligence of all white people. Small differences between very large, heterogenous populations gives you virtually no predictive power about individuals or how to help them, but do facilitate subtle and overt racism, however well-meaning it might be.
  - mrmffh 10y ago
    On what evidence can you say that more research won't/can't help? [1 SD is not a 'small difference'. (2 SD's if you compare to Ashkenazic Jews).]

      > On what evidence can you say that more research > won't/can't help On what basis can you say it will? These studies have known drawbacks in that they serve as a rallying point for all sorts of discrimination masquerading as high-minded discourse, and we're yet to see a benefit so far, so the burden of proof here is on you. At least part of the problem here is given two children / job-applicants / defendants / whatever, who are absolutely identical in every way except for a specific cosmetic phenotype, what possible justification is there for treating them differently based on correlation between that phenotype and some other characteristic over a large population?

        You are all over this thread putting words in people's mouths instead of discussing what they are actually saying. You are even painting an entire class of study with a broad brush in a guilt-by-association way. Are you sure that's actually helping your case and the conversation here?
        peteretep 10y ago
        What's an example of words I'm putting in someone's mouth? Perhaps you could reply specifically to a case where you believe I'm doing that?

You're arguing for deliberate ignorance because reality is uncomfortable. > At least part of the problem here is given two children / job-applicants / defendants / whatever, who are absolutely identical in every way except for a specific cosmetic phenotype, what possible justification is there for treating them differently based on correlation between that phenotype and some other characteristic over a large population? If two people are identical in every observable way, and that single observable way indicates a strong difference between them, why wouldn't one differentiate based on that single observation? They are, after all, indifferentiable in every other way. Indeed, mathematically speaking if one ignores the single useful datum you posit, then one will make worse decisions: if you have no other data and just flip a coin between greens and blues in your thought experiment a few posts back, then you will choose worse than if you bias your coin towards greens. That's just a fact; whether you choose to ignore it based on the discomfort it causes you is up to you.

The usefulness is if you see a deficiency in a student (or anyone) you can properly understand the reason for it. When you understand the reason you have a chance at actually making things better. I.e. use the data after seeing the performance of someone, rather than using it to predict their performance.
- peteretep 10y ago
  > When you understand the reason This right here is the problem. Armed with a small amount of data about information over a population on average gives you absolutely no information about any specific case, and the green-skinned child gets special treatment to bring them up to scratch, where the blue-skinned child gets written off as "she's achieving less well because blue-skinned children do". That's the problem, and that's why people in "polite societies" ignore these studies.
  - mhuffman 10y ago
    You realize there is not a small amount of data regarding racial IQ differences right? It is (was) one of the most studied social science fields before it fell out of fashion. You also seem to want to reduce something to skin-color that has been scientifically identified as more than skin color.
    - peteretep 10y ago
      Please could up explain the point you're trying to make? The first sentence suggests that you think my point is lack of evidence is a problem, the second suggests you think my argument relies on one specific factor rather than being generalisable to all.
      - mhuffman 10y ago
        Sure, there are two points: 1) Your point is based on ignoring often repeated and consistent (over decades) science; and 2) I think your argument generalizes something (to skin color) that is very specific (I.Q.) I will go further and say that I think you are being disingenuous about reducing the problems that affect different races to simply skin color.

However let's say the figure is 50%. Does the argument still follow? At what % would we inevitably be forced to pay attention? For instance, would anyone want to increase the chance of a violent encounter occurring in their workplace. Fortunately we can relax because these supposed assumptions currently belong in fairy land. 'Popularist'. Isn't it better to spell out what is meant here rather than use a word often by elites (self selected smaller powerful groups) to refer to any democratic decision of which the elite does not approve? It's one of those rolling stone expressions that saves its users time and effort by carrying with it a boat-load of subtext.

  > 'Popularist'. Isn't it better to spell out what is > meant here You're welcome to substitute the word "facile" if you've imbued "popularist" with too much meaning.
  - vixen99 10y ago
    That's much better! Of course I don't matter a jot but many folk who do (some EU leaders for instance) evidently believe 'populist' (as a word of derision - your implication, surely?) is indeed imbued with rich meaning of the kind they would prefer not to to spell out since their argument would then fall to bits.
- peteretep 10y ago
  > However let's say the figure is 50%. It's not. > Does the argument still follow? Yes. Given two people with similar academic achievements and no history of violence, discriminating between them is ridiculous. Treating individuals different based solely on their skin colour would still have no scientific or logical basis, as you'll still have many many stupid and violent green skinners, and peaceful and intelligent blue skinners. All that the "studies" will do is discourage natural bigots from looking at the traits of an individual. > At what % would we inevitably be forced to pay > attention? At the point where you could reliably extrapolate about a given individual based on their skin colour more accurately than you could based on their personal history to date.

> It's precisely because there's almost no practical use for studies like these (...) Let's say that green people have a higher rate of suicide attempts when they have mental illness X. This is very useful knowledge -- this means that one should treat X in green people more aggresively, because it's more dangerous for them. Let's say that green people are more likely to suffer from alcoholism. This is very important for green people themselves (they might prefer being teetolaters for that reason) and for organisations that try to prevent alcoholism -- they should target green people more in order to be more effective at decreasing the number of alcoholics. I can go on and provide such examples. Do you consider that in these cases there is still almost no practical use, that these examples are thought up and in real life you don't get such or something else?
- peteretep 10y ago
  > This is very useful > knowledge -- this means that > one should treat X in green > people more aggresively, > because it's more dangerous > for them. No you shouldn't, you should asses each patient individually, especially if - as per say qualification for a job - this fact is discernible by actually examining the person. Otherwise you will let a small 10% increase in likelihood for one group blind you to the needs of another.
  - wtbob 10y ago
    > No you shouldn't, you should asses each patient individually Assessment means making observations; making observations means observing; observing means actually opening your eyes to the facts as they are. You'd be killing your patients if you ignored the fact that greens commit suicide more often on average.

In that scenario, assuming a 50/50 population split of blue/green people, should you aim for having 50% of each employed at your company or are you justified in hiring fewer blue employees?
- peteretep 10y ago
  For a 10% difference? Unless you are employing a huge workforce where intelligence and peacefulness are the key features, I think you should be aiming for 50%. There are vanishingly few professions where you'll notice a 10% difference in IQ.

That seems a bit childish to me: one of the hallmarks of maturity is coming to terms with uncomfortable knowledge. Besides, here's one practical use for such a study: in your example, if blues were a much higher proportion of the prison population than they are of society at large, knowing that they are less intelligent and more violent on average is information which can help one determine if that is fair or not.

You should really read my whole comment instead of jumping on what you guess is in the book and what "study" you think the author performs. As noted in my comment, the author looks exclusively at white people. More importantly, he looks at a variety of long term (aka multi-decade) studies from a variety of US sources and analyzes that data. But if you want to keep arguing straw men, please feel free. I won't interrupt further.
