o.k. sorry. I dropped a bomb on this thread early in the morning and then I got dragged away from the computer kicking and screaming by the day's emergencies. I really wanted to explain myself.
Well, first I find it offensive just on an ethical/human level. To be able to generalize to a culture, a race, a nation, a economic class like that is just wrong in so many ways I likely could spend the rest of my life listing them. That is, if the basic assumptions on which it is based are correct in the first place.
I could find more intellectually justifiable merit in a ranking of basketball skills by race, culture, and country than a IQ test as a way to allocate resources and social justice. At least basketball skills (or the lack of them) is something I could say exist (or even does not exist). The IQ test ( specifically the existence of general intelligence as some sort of quantifiable number) has trouble even passing the existential and epistemological smell test. As theoretical type things go that is a fairly low hurdle to get over.
Second, on a personal academic level I find it insulting. I do believe there is such a thing as "intelligence", and perhaps it is measurable in some way. I spent something around 8+ years of my life (philosophy moves a little slower than other fields), and I bet with various government educational subsidies better than $250,000 US at Universities in the States and Europe specializing in areas related to "intelligence", thought, minds, AI, and so on. I am still in a PhD. program, just a little burned and not doing much lately.
So, it really rubs my philosophical intuitions the wrong way to have a bunch of intellectual lazy psychologist arbitrarily declare a definition and the problem solved, and then use it to stick square pegs in round wholes (pun intended).
I was far from the first sucker to step in to that quagmire. We are talking about one of the problems that humanity has devoted likely more thought to solving than any other subject. Perhaps even more than religious thought and God. The issue might even be the source of our desire to know God, or at least intimately related to that urge. There is very good anthropological evidence that the issue was grappled with long before recorded history (e.g. totems, spirits, and so on). So, again it just makes my skin crawl when I hear it used in any context (there are few good ones to use it in).
So to simply assert that X is Y, just does not make it true.
There is no way we can get in to all the gory details on this forum. There are entire regions of the internet devoted to this subject. There are entire libraries, buildings, departments, and so on devoted to it in some way, shape, or fashion filled with people that know a lot more about it than I do anyway.
As far as I have been able to determine, intelligences is first and foremost tied to language. No language, no culture, no mind, no thought, no IQ test. In fact, under the philosophical microscope culture, language, and thought are almost indistinguishable. Intelligence, no matter what else it might be is something that is communicated. To measure it, you must do it through language. That is in part the problem, and why we do not have computers that can Think ( big T ). Talking refrigerators are not problem. No one however in the computer science world working in AI that I know of is considering giving a computer an IQ test. In fact, I think programing a computer to defeat (not simply score well) an IQ test would be a rather trivial programing trick. There would still be no lights on upstairs as we like to say in Philosophy.
Language, at the end of the day, seems to be not much more than a set of norms and behaviors. They are often highly formalized in to what we call English, Spanish, Chinese, and so on, but they do not need to be to qualify as intelligence. I might point to cases such as Helen Keller, Coco the Gorrilla, my cat complaining that it does not like the cheap cat food I bought. All of which exhibit some form of behavior that we would easily identify with as intelligence, but I believe we would have trouble administering a standard IQ test to them with any meaningful results. So too, would we have trouble putting say a random person or group from Africa up against say a random person or group in Chile.
So, at the very least it can not be quantified in the way they claim to have quantified it. Even if they could, there is no World in which I can imagine that we could find a group of say Chinese, Germans, Americans, Chileans so equal in all respects as to make such comparisons of the numbers meaningful.
Sorry, it is too involved for me to fully unpack my thoughts on language and intelligence in any sort of coherent way here, but I would direct anyone who would like to follow up the issue to read the works of Wilfred Sellers. His most important work is
EMPIRICISM AND THE PHILOSOPHY OF MIND for those with better things to do, but still not that much better than reading his other 30 or so books and 1,000 or so articles.
The text is online at this link below. To really work it over you will want a paper copy, and the rest of your life.
http://ditext.com/sellars/epm.htmlThe shorter versions and biography are here:
http://plato.stanford.edu/entries/sellars/http://www.ditext.com/sellars/index.htmlHonestly, I believe Sellers will go down in history as one of the greatest philosophers ever. Right next to Plato, Hume, and so on. The biggest guns in Philosophy and Artificial Intelligence have been talking about it before he was even dead. In fact, I once pulled a book off the shelf titled something like
In honor of the life and works of Wilfred Sellers. He wrote the introduction, and was still alive at the time it was published. If I had found
EMPIRICISM AND THE PHILOSOPHY OF MIND my first year in Philosophy, I likely could have saved a lot of money or at least time. Unfortunately, my mentor played a cruel joke on me and did not hand me a copy until my last year of undergraduate work, and thousands of hours of mental torture at the hands of other thinkers. I almost did not bother going to graduate school because of it.
As Philosophy goes, this is likely one of the shortest and most accessible books ever written that manages to make sense out of almost the entire history of Philosophy and Science in around 400 or so pages (well more than anyone believed could be done in 400 pages). Most people that have never read a Philosophy text in any depth will likely be confused by the how common sense it is. That is likely why philosophers, anthropologist, linguist, computer scientist, and people from just about every other field are still scratching their collective heads over it. It seems the only people that have not found it yet are in psychology departments typing up the latest versions of the IQ test. Perhaps they have, and just prefer to collect their snake oil royalties.
