Yes, IQ research is subject to political pressure when it makes statements about public policy. Just like everyone else is subject to political pressure when they make statements about public policy. No doubt that has led some IQ researchers deciding that they're not being given a fair shake. But scientists who do understand what they're doing, who do understand the methods, and the statistics, and the evidence, do not tend to support these claims. Which is why they are limited to a subset of IQ researchers, rather than accepted across the discipline as a whole.
There is a set of claims made by the MAJORITY of intelligence researchers but not the majority of other psychologists, i.e. that intelligence as measured by intelligence tests are central to making sense of human economic inequality and that the racial differences in average intelligence scores are mainly genetic.
Those are not claims made by a majority of intelligence researchers.
Look, the majority of intelligence researchers, by sheer numbers, are working in industry trying to fit IQ and other forms of psychometric testing to management and HR policy, either internally or as consultants. They're not in the business of making sweeping claims, they're in the business of filtering job applicants.
There is a noisy subsection of intelligence researchers, as there is in any subject, who want to push the case that their work is not just of interest to a niche subsection of psychology department, but is key to understanding the world. This is why Dawkins describes the theory of evolution as the pinnacle of human achievement, why physicists keep trying to make out that all other forms of science are simply variations on physics, why historians claim that you without understanding the past it is impossible to understand the present, and why the National institute of Actuaries claims that 'understanding insurable risk is the key to navigating the economic hazards of the 21st century'.
Those are politically controversial points that do not so directly follow from a narrow range of data but only from a broad comprehension of a diversity of data and a sound theoretical understanding unique to intelligence researchers.
But that's just it - it isn't unique to intelligence researchers. Why would it be? Why wouldn't any psychologist, including those who disagree with intelligence researchers, understand it just as well?
If you really believe that only an expert in a subject can ever understand it, then we have to assume that public policy pronouncements by intelligence researchers are false, because they aren't experts in public policy, and thus can never understand it. Or you can believe that other people can understand the subject, in which case the notable lack of support of those noisy intelligence researchers by mainstream psychology because a very significant problem. Because here are scientists who understand the measures, understand the statistics, understand the methods the evidence and the reasoning, and think they're talking rubbish. You can't just hand wave that away.
But, there are other conclusions that follow directly from a narrow range of data, they are accepted broadly among psychologists of all disciplines, and they are still at odds with the common thinking of the public, such as the points that intelligence score variations within groups are mostly heritable and that racial and class gaps in average intelligence scores exist.
But not that much at odds. Heritable doesn't mean genetic. Income is extremely heritable. Class gaps aren't much of a problem for the public. And while race gaps are there in the measurements, they're not nearly as much of a problem as the idea that your children are way smarter than you are. The gulf between one generation and another makes the race gap look trivial. Anyone in favour of limiting the voting age to a maximum of 35?
Really the main gap between the public and the narrow realities of IQ testing is the thorny problem of understanding what statistics do and do not mean.
All the points listed in the article "Mainstream Science on Intelligence" are of that nature (
http://www.udel.edu/educ/gottfredson/reprints/1997mainstream.pdf).
No, they aren't. The points listed in the article include many of the points of difference between a subset of intelligence researchers, and mainstream psychology.
I don't think it is right to be inclined to dismiss the whole field of intelligence research the same way you would dismiss the consensus of opinions of a political party,
People who express political opinions should get treated like political parties. The opinions being expressed by these people are political opinions loosely based on a particular interpretation of the science. If there was evidence for their interpretation above any other, I'd be more inclined to listen to them.
because intelligence researchers really do know the most about what they are talking about, they are credentialed professors of state-accredited universities, they publish mainly in reputable peer-reviewed journals (really not so much in the popular media), and they really are well-respected by their colleagues in related fields.
So why are their claims being published in op-ed articles in the newspapers rather than in those same peer-reviewed journals? The answer, I suspect, is because you can't make many of those claims in a peer-reviewed journal, because your peers will want to know how you are proving these sweeping and inaccurate statements. Researchers found that, in a particular study, poor white respondents scored similarly in tests to rich black respondents. Fine. Peers will want it made clear that rich and poor were fairly arbitrary measures, they'll want to see the details of how the subject pools were put together, and what statistical tests were used, and they'll be able to conclude for themselves whether the study really allows you to generalise about an entire phenotype of society that aren't even a genetically coherent group. But in a book or newspaper article, you can push whatever agenda you want. Want to claim that your special research allows you to pre-select winning lottery tickets - go right ahead! Want to claim that IQ researchers are better in bed - build that harem! Want to claim that you and your colleagues alone understand how to rate people's mental potential? Go right ahead!
This problem is not unique to intelligence research. This is why we get AI researchers talking about the world being overtaken by robots within 10 years, at least every 10 years. Why we had that horrible and damaging public slanging match about the efficacy of drug treatments for incurable mental conditions, why we had Skinner trying to claim that operant conditioning was key to turning society into a utopia. and so on and so forth.
They tend to claim that there is a widespread culture (not a conspiracy) that silences, distorts, misrepresents, misunderstands, discredits and dismisses their opinions, I think it needs to be taken a little more seriously.
It's probably true. Since I don't get my opinions of their work from the media, though, but rather from the studies and fellow scientists, I'm not sure why it matters. Why not just look at the studies and reason through the problem yourself? If you understand the criticisms made, maybe you won't be so quick to dismiss them?
