This topic has been coming up a lot around BAUT and I thought it was a good idea to see what it's about.

The controversy comes in the IQ tests. Some think it is an inaccurate way of measuring intelligence. I think the only good thing intelligence can be used in is to solve a problem. For this a lot of pattern recognition, data processing, abstract-thinking, creativity, etc is needed. Since IQ tests involve usage of these skills, they cannot be too much off as a reasonable measure of intelligence.

Of course, a base definition of intelligence itself is required for this question to have any meaning.

Of course it can, obviously; those who say otherwise are just denying reality because reality happens to be unfair and they prefer to project an image of a fair world even though it's false. It's no different from filling kids' heads with that tired old "everybody's got some special talent" crap and telling them that "there's someone for everyone", as if that could seriously protect them from the realities of uneven talent distribution and unequal romantic prospects.

To further complicate this already impossible task is this. Who decides?
The Wall Street banker needs a set of very different survival skills than a Tropical rain Forrest inhabitant. That tropical Forrest dweller has the ability to adapt does the other...? well yes. He might have. Will he ever need to? No. So two very different skill levels emerge. With breding and culture we polarize our point of view. It does not measure inelegance.
The survival of humanity is perhaps a direct result of our ability to be flexible. The want to survive is very strong and we adapt very well to all of Earths extremes.
For me the standard IQ test is tainted with irrelevance..
I too, agree with the point we should not tell children lies. Life is hard. Get used to that. Its true.

Some aspects of inteligence can be measured. How accurate those measurement are is an open question at this point.

True, different skills. But both of these professions involve use of problem solving skills.

What type of irrelevance?

To echo aspects of what others have said (this is just my opinion, I'm no expert), some quality or qualities called "intelligence" can be measured, and given that the tests are testing fairly specific things (like certain facts and certain things like pattern recognition), they are probably pretty accurate. But, that leads to the question, so what? Are those measures good predictors of anything, beyond how one does on an intelligence test? The measures that make you a good computer programmer or brain surgeon are not necessarily those that make you a good farmer or a hunter-gatherer, or for that matter a good parent, spouse, or citizen.

Just having a debate about this on another forum. The question is a matter of precision. It would be rather easy to tell the difference in intelligence between someone with a (measured) IQ of 60 and someone with a (measured) IQ of 120. And that without even having to define intelligence precisely. The problem is with differences that are a lot closer than that.

Between widely different IQ tests, there may be small variations in results, but generally, the results will be close. The precision of the results from the tests depends upon the precision of the definition of intelligence.

On a somewhat lighter (and maybe heavier) note concerning this subject, a student writer for a high school newspaper got in a lot of trouble, causing the principal to confiscate the newspaper.

http://www.ajc.com/blogs/content/sha..._over_e_c.html

He wrote a piece in the spirit of Swift, noting that stupid people seem to reproduce more than smart people and something needed to be done. He suggested just putting the lower 1/4 out of their misery.

Principal had a cow at that, even knowing it was an obvious joke.

The editor of that paper wrote another piece criticizing the school's beauty pageant, which also didn't go over too well.

Accuracy is one problem, a very serious problem when you are making decisions about one individual, because at the level of the single individual they can be exceedingly inaccurate.* If someone panics when doing a test under time pressure, it won't be just a couple of points they are down. But statisticians looking at the results for many individuals may believe that these errors tend to average out, over the populations.

But unfortunately they don't. There are systematic differences between population groups in accuracy of the tests. We might say that the differences between individuals according to their experience of doing problems written on paper, their experience of doing tests under time pressure, their ability to understand the problems in the manner presented to them, etc, will average out. Practice in doing the tests also seems to increase scores. But the reality is that there are systematic differences in these things between groups of the population. The disadvantaged are less literate, not because they are less intelligent, but because they are disadvantaged. And this will substantially impact on their ability to perform in the test.

As Stephen Pinker points out, it seems likely that people who live in difficult, complex environments with a high selection pressure are more intelligent than people who live in protective societies with low mortality. He says that in his experience New Guinea natives are a lot more switched on than typical Americans. I wonder what kind of test would be a reasonable measure of the intelligence of a New Guinea native with no formal western-type education. Nor does it surprise me that Jews perform so well, they have had very strong selection pressure on them.

* I was especially unamused by the result of a test which said that I wasn't clever enough to go to a [high] school I was already at, where I was top of the class and advanced a year group. We used to do systematic intelligence testing in Britain in order to select which school people would go to at age 11.

Yes.

Very simple answer, but it does depend on how you define intelligence.

If you define it as the ability and speed with which information is aquired and put to use; then yes, intelligence can definitely be measured.

If you define it with all kinds of goofy, new age, pop psych, fluffy politically correct terms and ideas, (such as emotional intelligence and similar garbage) then it becomes impossible to get a handle on the definition, much less measure it. Which is really what proponents of such gibberish want; so everybody can be equal and noone is offended by having the fact that they are dumb as rocks called out.

Next question please.

We can't conveniently measure intelligence, no. But as Noclevername suggested, we can measure aspects of intelligence. Problem solving (Mensa/IQ), general knowledge (SAT type tests), ability to take tests (all of the above).

Where "we" trip up is by equating testing ability (of various kinds) with intelligence. There may well be a correlation between tests and intelligence, but they're not equivalent.

I think we can make a fairly accurate measure of intelligence.

However intelligence by itself cannot accurately predict success.

Intelligence alone does not account for self-motivation and drive and a willingness to take risks - which are all pretty significant factors in the success of an individual. Far stronger factors than basic pattern recognition.

Very good distinction. I think a lot of people so strongly resist the measurements because of what they think it says about them. All it says is you have x ability to assimilate and process information. It does not make you a winner or loser or most likely to succeed or most likely to live in a van down by the river.

But people make it mean so much more, then out of fear of how it might apply to them, obfuscate/complicate the issue to the point of paralysis.

Sometimes a cigar is just a cigar.

Are you SURE principal knew it was a joke?

Some people have no sense of humor. Some others check theirs in when they arrive to work.

Fiction has to be plausible. Reality is under no such constraint.

One of my questions concerns the decoupling of a general concept of intelligence from the evolutionary idea of differential reproductive success in a local environment. Intelligence, no matter how you slice it, is like a lever; to estimate it you need a fulcrum, whose position will vary depending on the local conditions, or may not exist at all. As a homely example, if two people (one can swim well, one has never learned how) fall out of a boat in the middle of a storm in a lake, it is much more likely that the one who knows how to swim will survive to get to the shore. 'General problem solving ability' is much less valuable in this instance than strength and previous experience. All I mean by this is that intelligence is not necessarily a universal positive; there are times when the selection process can look right through it, or even select against it.

I also have a question about the determination of IQ itself, stemming from my ignorance of the minutae of its measurement. While looking at articles here and there I ran across mention that written IQ tests are designed to produce a normal distribution of outcomes. Is there any a priori reason (beyond the central limit theorem) to assume that such measurements are inherently closely related to the normal distribution? I mention this because I have seen arguments about intelligence ranking among populations and the distribution of 'geniuses', using the small difference in mean scores to extrapolate the numbers of smarties out four or five standard deviations. Looking at the size of those statistical tails is critically dependent upon the actual population following a normal distribution. If it does not, then such extreme extrapolations are unjustified.

One of the reasons that IQ tests try to focus on pattern recognition and generic computation is to try and isolate as much of the cultural background out of the picture as possible.

Comparing skillsets is trivial, intelligence can be derived from how well those individuals mastered those skillsets from the time of their first exposure to them to the time they learned to put them to use.

I'm not sure I understand your point here. Not a cut, by any means, it just isn't penetrating my noggin.

This, on the other hand, does go back to my first question, which asks if the mere fact of such isolation skews the results, since success takes place in a local time and place, not some abstract space.

The result is less important than the process. How quickly, and how ably can a person learn to assimilate, immitate, and then innovate, skills that they're exposed to.

How well do they absorb information, how well do they process and apply it, and how well do they do when the time comes to improvise with those skills based on circumstances to which they weren't expressly trained to handle.

Very simple answer, but it does depend on how you define intelligence.

If you define it as the ability and speed with which information is aquired and put to use; then yes, intelligence can definitely be measured.

If you define it with all kinds of goofy, new age, pop psych, fluffy politically correct terms and ideas, (such as emotional intelligence and similar garbage) then it becomes impossible to get a handle on the definition, much less measure it. Which is really what proponents of such gibberish want; so everybody can be equal and noone is offended by having the fact that they are dumb as rocks called out.

Most common forms of IQ testing tend to focus on fairly limited definitions of intelligence. However, despite the psycho-babble component, there are different forms of intelligence. I've known people who are geniuses when it comes to dealing with mathematics and/or science who are morons when it comes to dealing with people (a stereotype that is sometimes true). Some people couldn't solve a calculus problem if their life depended on it but have a high degree of mechanical aptitude. My brother in law can fix just about anything (he's a retired pipefitter) even though he never finished the 10th grade.

Solving math problems, dealing with people, and mechanical aptitude represent different types of intelligence, IMO. No one test or number is going to measure that.

Not long ago, I was watching Yo Yo Ma play a complex cello piece with an orchestra. He played this piece entirely from memory. Musical ability on that level is, I suspect, more than rote memorization. I'd say that Yo Yo Ma is a musical genius whether he can fix things or solve math problems or not.
