VOX Goes From “junk” To “no good”: That’s a Bit of Intelligent Progress

I dislike writing responses to articles I feel need correction or clarification. As a journal editor, I do it frequently. In this case, I’m writing a response to a response about responses to a response. By way of introducing this piece, VOX published a critical article about a podcast discussion between Sam Harris and Charles Murray with a disparaging headline about “junk science.” The issue was whether any scientific data support the idea that group differences in average IQ scores might be partially explained by genes (a very minor part of the podcast). The VOX piece thought this possibility was junk. I submitted a response to VOX; they declined to publish it but Quillette did (June 11). VOX then published a second piece where the authors of the original piece responded to a number of online criticisms in considerable technical detail. That second piece had a headline of “still no good reason” to believe genes had anything to do with group differences. In my view, this article was much better than the first and the …

Are Liberals Dying Out?

By now there is a huge body of literature in behavioral genetics, which shows that pretty much every psychological characteristic we can measure is to some degree heritable. This raises a question that has received little discussion beyond academia – what about political views? Are they heritable? And if so, what does this mean for the political landscape of future generations? The evidence for the heritability of psychological traits is immense. The authors of a recent meta-analysis published in Nature Genetics looked at 2,748 publications surveying 17,804 traits. They found that “estimates of heritability cluster strongly within functional domains, and across all traits the reported heritability is 49%.” These results shouldn’t be surprising. If offspring didn’t resemble parents to some degree, evolution as we understand it could not occur. Indeed, according to the Darwinian paradigm, evolution takes place through variation and selection. Imagine, for example, that you wanted to domesticate a wild animal. Foxes are cute, so let’s talk about them. One thing we know about foxes is that some of them are naturally aggressive, …

No Voice at VOX: Sense and Nonsense about Discussing IQ and Race

Sam Harris, a noted commentator, recently had a podcast discussion with Charles Murray about the reaction to the publication of The Bell Curve in 1994. It is an informative, respectful discussion and I urge you to listen to it. Shortly after this podcast, the popular online news site VOX.com, ran a piece with the headline: “Charles Murray is once again peddling junk science about race and IQ—Podcaster and author Sam Harris is the latest to fall for it.” The piece mostly restates old arguments that continue to misrepresent what The Bell Curve actually said about race and genetics. It is based on a selective reading of the research literature and the assertion of facts that are not supported by a weight-of-evidence. There is nothing new or original in the arguments and these arguments have been challenged many times by other experts in the field. Nonetheless, VOX gave new life to the false narrative that Murray is “peddling junk science” about average IQ score differences among racial/ethnic groups being genetic and therefore some groups are genetically inferior. The …

A Risk Not Worth Taking: An Open Letter to My Colleagues in The Academy

Dear Colleagues: What an interesting world we inhabit in 2017. On one hand, there has never been a better time to be alive. Violence has been declining for some time, vaccines ward off previously intractable diseases, and basic human rights have continued to creep into parts of the world where they were previously absent. Yet, at the same time, we find ourselves increasingly polarized in certain respects. What we do as scholars invariably becomes injected into the heart of many of these key societal debates. Basic empirical questions—such as “is the world getting warmer, and if so, are we humans causing it to happen?” can ignite strong feelings and heated rancor. You don’t have to study climate to find yourself swept up in the fray, either. Almost no corner of science is fully immune from stoking a controversy. It is because of this reality, that I write to you. Never in the history of our species have we understood so much about the world we inhabit. I mean that we truly understand it. We have …

Getting Voxed: Charles Murray, Ideology, and the Science of IQ

“The impulse to think that environmental sources of differences are less threatening than genetic ones is natural but illusory.” Charles Murray “Convictions are more dangerous enemies of the truth than lies.” Friedrich Nietzsche   Recently, the popular online political outlet Vox published an article in response to Charles Murray’s interview on Sam Harris’s “Waking Up”1 podcast that illustrates the insidious effect ideology can exert on science. The article, written by a group of esteemed scholars, Eric Turkheimer, Kathryn Paige Harden, and Richard E. Nisbett, contended that Murray is still “peddling junk science” about race and intelligence, thereby duping otherwise critical scholars like Harris with pseudo-scholarship and sophistry. The article attempts a moderate, scientifically sound criticism of hereditarianism (i.e., the contention that at least part of the Black-White IQ gap is genetic). Unfortunately, the result is a tendentious and ideologically skewed attack on Murray that forwards cherry picked studies, ignores copious data, and dismisses the impressive explanatory power of hereditarianism with a wagging finger of moral disapproval. Turkheimer et al did not dispute many of the most important points discussed …

Censorship, the Authoritarian’s Snake Oil

Of all the many world-changing inventions that have come from the field of particle physics, few are more prominent than the World Wide Web. Invented in 1989 by Tim Berners-Lee as a tool for sharing data with other scientists at CERN, the Web was based on a simple yet powerful idea: that a single mouse click could take you from one page to another, anywhere else on the planet. Berners-Lee was remarkably forward-thinking, proposing not only rich content like images or video, but also that the Web should be an interactive and democratic medium, where every user has the power to speak as well as listen. The millennium gave us blogs, wikis, and social media, at which point Berners-Lee’s dream was (sort of) realised, and the internet grew from a toy for geeks into a public utility as ubiquitous as electricity or television. The rest, as they say, is history. But where science leads, lawyers and politicians inevitably follow. It didn’t take long for the self-appointed moral guardians to arrive on the scene, realise that …

Paradoxes of Probability and Other Statistical Strangeness

You don’t have to wait long to see a headline proclaiming that some food or behaviour is associated with either an increased or a decreased health risk, or often both. How can it be that seemingly rigorous scientific studies can produce opposite conclusions? Nowadays, researchers can access a wealth of software packages that can readily analyse data and output the results of complex statistical tests. While these are powerful resources, they also open the door to people without a full statistical understanding to misunderstand some of the subtleties within a dataset and to draw wildly incorrect conclusions. Here are a few common statistical fallacies and paradoxes and how they can lead to results that are counterintuitive and, in many cases, simply wrong. Simpson’s paradox This is where trends that appear within different groups disappear when data for those groups are combined. When this happens, the overall trend might even appear to be the opposite of the trends in each group. One example of this paradox is where a treatment can be detrimental in all groups …
