According to The Bell Curve, Black Americans are genetically inferior to Whites. That's not the only point in Richard Herrnstein and Charles Murray's book. They also argue that there is something called "general intelligence" which is measured by IQ tests, socially important, and 60 percent "heritable" within whites. (I'll explain heritability below.) But the claim about genetic inferiority is my target here. It has been subject to wide-ranging criticism since the book was first published last year. Those criticisms, however, have (...) missed its deepest flaws. Indeed, the Herrnstein/Murray argument depends on conceptual confusions that have been tacitly accepted to some degree by many of the book's sharpest critics. (shrink)

How can we disentangle the neural basis of phenomenal consciousness from the neural machinery of the cognitive access that underlies reports of phenomenal consciousness? We can see the problem in stark form if we ask how we could tell whether representations inside a Fodorian module are phenomenally conscious. The methodology would seem straightforward: find the neural natural kinds that are the basis of phenomenal consciousness in clear cases when subjects are completely confident and we have no reason to doubt their (...) authority, and look to see whether those neural natural kinds exist within Fodorian modules. But a puzzle arises: do we include the machinery underlying reportability within the neural natural kinds of the clear cases? If the answer is ‘Yes’, then there can be no phenomenally conscious representations in Fodorian modules. But how can we know if the answer is ‘Yes’? The suggested methodology requires an answer to the question it was supposed to answer! The paper argues for an abstract solution to the problem and exhibits a source of empirical data that is relevant, data that show that in a certain sense phenomenal consciousness overflows cognitive accessibility. The paper argues that we can find a neural realizer of this overflow if assume that the neural basis of phenomenal consciousness does not include the neural basis of cognitive accessibility and that this assumption is justified by the explanations it allows.

Philosophers of mind (from eliminative materialists to psychofunctionalists to interpretivists) generally assume that a normative ideal delimits which mental phenomena exist (though they disagree about how to characterize the ideal in question). This assumption is dubious. A comprehensive ontology of mind includes some mental phenomena that are neither (a) explanatorily fecund posits in any branch of cognitive science that aims to unveil the mechanistic structure of cognitive systems nor (b) ideal (nor even progressively closer to ideal) posits in any given (...) folk psychological practice. Indeed, one major function of scientific psychology has been (and will be) to introduce just such (normatively suboptimal but real) mental phenomena into folk psychological taxonomies. The development and public dissemination of IQ research over the course of the 20th century is a case in point. (shrink)

Psychometric g—a statistical factor capturing intercorrelations between scores on different IQ tests—is of theoretical interest despite being a low-fidelity model of both folk psychological intelligence and its cognitive/neural underpinnings. Psychometric g idealizes away from those aspects of cognitive/neural mechanisms that are not explanatory of the relevant variety of folk psychological intelligence, and it idealizes away from those varieties of folk psychological intelligence that are not generated by the relevant cognitive/neural substrate. In this manner, g constitutes a high-fidelity bridge model of (...) the relationship between its two targets and, thereby, helps demystify the relationship between folk and scientific psychology.

A pluralistic approach to folk psychology must countenance the evaluative, regulatory, predictive, and explanatory roles played by attributions of intelligence in social practices across cultures. Building off of the work of the psychologist Robert Sternberg and the philosophers Gilbert Ryle and Daniel Dennett, I argue that a relativistic interpretivism best accounts for the many varieties of intelligence that emerge from folk discourse. To be intelligent is to be comparatively good at solving intellectual problems that an interpreter deems worth solving.

Several hundred thousand intellectually talented 12-to 13-year-olds have been tested nationwide over the past 16 years with the mathematics and verbal sections of the Scholastic Aptitude Test (SAT). Although no sex differences in verbal ability have been found, there have been consistent sex differences favoring males in mathematical reasoning ability, as measured by the mathematics section of the SAT (SAT-M). These differences are most pronounced at the highest levels of mathematical reasoning, they are stable over time, and they are observed (...) in other countries as well. The sex difference in mathematical reasoning ability can predict subsequent sex differences in achievement in mathematics and science and is therefore of practical importance. To date a primarily environmental explanation for the difference in ability has not received support from the numerous studies conducted over many years by the staff of Study of Mathematically Precocious Youth (SMPY) and others. We have studied some of the classical environmental hypotheses: attitudes toward mathematics, perceived usefulness of mathematics, confidence, expectations/ encouragement from parents and others, sex-typing, and differential course-taking. In addition, several physiological correlates of extremely high mathematical reasoning ability have been identified (left-handedness, allergies, myopia, and perhaps bilateral representation of cognitive functions and prenatal hormonal exposure). It is therefore proposed that the sex difference in SAT-M scores among intellectually talented students, which may be related to greater male variability, results from both environmental and biological factors.

Perhaps it is best to begin on a semi-autobiographical note. In my liberal days, Mill's arguments in On Liberty for freedom of speech struck me as a paradigm of rationality: the force and eloquence of his presentation, I then thought, could not fail to impress themselves on any mature member of our species. But I am a Marxist now, and more and more of my former political beliefs now strike me as less and less tenable. It was considerations such as (...) the one that follows which have recently led me to modify drastically, and in some cases abandon entirely, my former political views vis à vis the question of freedom of speech.Whenever there is an ascendant class, a large portion of the morality of the country emenates from its class interests and its feelings of class superiority. The morality between Spartans and Helots, between planters and negroes, between princes and subjects, between nobles and returiers, between men and women, has been for the most part the creation of these class interests and feelings ….

It is, perhaps, a propitious time to discuss the economic rights of disabled persons. In recent years, the media in the United States have re-ported on such notable events as: students at the nation's only college for the deaf stage a successful protest campaign to have a deaf individual ap-pointed president of their institution; a book by a disabled British physicist on the origins of the universe becomes a best seller; a pitcher with only one arm has a successful rookie (...) season in major league baseball; a motion-picture actor wins an Oscar for his portrayal of a wheelchair-bound person, beating out another nominee playing another wheelchair-bound person; a cancer patient wins an Olympic gold medal in wrestling; a paralyzed mother trains her children to accept discipline by inserting their hands in her mouth to be gently bitten when punishment is due; and a paraplegic rock climber scales the sheer four-thousand-foot wall of Yosemite Valley's El Capitan. Most significantly, in 1990, the United States Congress passed an important bill – the Americans with Disabili-ties Act – extending to disabled people employment and access-related protections afforded to members of other disadvantaged groups by the Civil Rights Act of 1964.

Four lines of argument are adduced to support the contention that current disease-modeled approaches to learning disability (LD) are inadequate and that a more environmentally-centered approach should be utilized. The first argument employs philosophy of science to criticize the blatant operationalism of the extant theorizing, while noting that the theories frequently try to employ a realist slant. The second line of argument attacks the disease model itself, employing the work of other philosophers who have noted the extent to which "disease" (...) is a value-laden construct. Still another line notes that, at first glance, current work on paternalism might seem to provide some kind of rationale for LD placement, but that this is probably not the case. The fourth line of argument adverts to the possibility that sociopolitical motivations underlie some of the labeling efforts. It is concluded that current efforts are fruitless and that a new definitional effort is needed, one which specifically cites the locus of disability as the classroom environment. (shrink)
