A book that challenges common misconceptions about the nature of intelligence

Satoshi Kanazawa's "Why Beautiful People Have More Daughters" (written with Alan S. Miller) was hailed by the "Los Angeles Times" as ""a rollicking bit of pop science that turns the lens of evolutionary psychology on issues of the day."" That book answered such burning questions as why women tend to lust after males who already have mates and why newborns look more like Dad than Mom. Now Kanazawa tackles the nature of intelligence: what it is, what it does, what it is good for (if anything). Highly entertaining, smart (dare we say intelligent?), and daringly contrarian, "The Intelligence Paradox" will provide a deeper understanding of what intelligence is, and what it means for us in our lives.Asks why more intelligent individuals are not better (and are, in fact, often worse) than less intelligent individuals in solving some of the most important problems in life--such as finding a mate, raising children, and making friends Discusses why liberals are more intelligent than conservatives, why atheists are more intelligent than the religious, why more intelligent men value monogamy, why night owls are more intelligent than morning larks, and why homosexuals are more intelligent than heterosexuals Explores how the purpose for which general intelligence evolved--solving evolutionarily novel problems--allows us to explain why intelligent people have the particular values and preferences they have

Challenging common misconceptions about the nature of intelligence, this book offers surprising insights into the cutting-edge of science at the intersection of evolutionary psychology and intelligence research.

Nota de la solapa

Seventeenth-century political philosopher Thomas Hobbes once observed that intelligence must be equally distributed among humans, because no one ever complained that they didn't get as much as everyone else. Of course, that was before the invention of the IQ test prompted a series of objections that the tests were biased and/or inaccurate, that intelligence can't really be measured, and that there are multiple types of intelligence. For well over a century, intelligence and what it means have been the source of endless controversy. Here comes more.

In The Intelligence Paradox, the coauthor of Why Beautiful People Have More Daughters, Satoshi Kanazawa challenges the common misconceptions about what intelligence is and what it is not, how it is measured, what it's good for, and what it's bad at. He also makes many controversial statements: liberals are, on average, more intelligent than conservatives; atheists are more intelligent than believers; and homosexuals are more intelligent than heterosexuals. And using the latest research, he shows each one to be true.

At its core, Kanazawa's message is that intelligence, while certainly an asset, is one human trait among many, and it is in no way a measure of human worth. He reveals how the purposefor which general intelligence evolved--solving evolutionarily novel problems that were rarely encountered during life on the savanna--allows us to understand why the most intelligent people have the particular values and preferences they have. He also explains why, despite their huge brains, the most intelligent people are often less successful than their less intelligent relatives at solving life's most important problems.

Kanazawa uses the findings of several large long-term studies to examine the relationship between intelligence and numerous preferences and values. What he discovers is often surprising and sometimes, indeed, paradoxical. Intelligent men, for example, are more likely than less intelligent men to value sexual exclusivity for themselves, yet also more likely to cheat on wives or girlfriends despite what they really want. Why are intelligent people more likely than less intelligent people to be night owls and late sleepers? Precisely because it is unnatural. It may not surprise you to learn that intelligent people are more likely to prefer classical music to pop--but why on earth would they also like elevator music?

Intersecting the fields of evolutionary psychology and intelligence research, The Intelligence Paradox is guaranteed to change the way you think about all that thinking you do.

5.0 de un máximo de 5 estrellas Intelligence From an Evolutionary Perspective: A Confirmation of Common Beliefs 16 de junio de 2012
Por Reviewer_in_DC - Publicado en
Formato: Tapa dura Compra verificada
A hardcore evolutionary psychologist and avowed enemy of "political correctness" and other recent cultural brainwashing afflicting modern society, Satoshi Kanazawa is no stranger to controversy. In his latest book, he again takes the reader on the journey of blunt and unapologetic evolutionary reality. The latest social question he tackles is, What is intelligence, and why did it evolve?

Intuitively, we all know who intelligent people are, and their likely behaviors. On paper, they are high achievers, who rise to the top ranks of modern society thanks to their academic talents and aptitude; but upon closer examination, these seemingly successful people are socially awkward, lack common sense, and often hold bizarre, unrealistic beliefs. "More intelligent people are more likely to be 'stupid' (lacking common sense), whereas less intelligent people are more likely to be 'smart' (possessing functional common sense)," Kanazawa writes, noting the paradox.

Where does the paradox come from? Kanazawa's thesis is that the majority of people (who, by definition, are not intelligent), are good at "Evolutionarily-Familiar" tasks. "Evolutionarily-Familiar" problems ("EF") are those that have always existed throughout evolutionary history. "Mating, parenting, social exchange, and personal relationships" are, according to Kanazawa, some of these ultra-familiar, ultra-prominent "EF" problems that all social animals have always had to deal with. Humans and other primates have always mated, raised children, made alliances, related to others, sought out nutritious food, and avoided predators.

A fraction of people, however, are very good at "Evolutionarily-Novel" tasks ("EN"). These are new, unusual domains of life which have never before existed in our evolutionary past. As Kanazawa notes tongue-in-cheek, "There is no common sense about how to boot up a Macintosh computer or how to fly an airplane." But it is precisely these people, defined as "intelligent" based on a series of objective tests, who excel at such new, academic, high-level "EN" tasks.

So intelligent people are those who are very good at adapting to unusual, new situations. "Stupid"/non-intelligent people are those who are very good at familiar, ancient tasks. That is the distinction, and several interesting predictions result from it:

- Liberalism/Marxism/Left-wing values: The idea of supporting others who are not related to you, is "unusual" in evolutionary terms, because it is contrary to traditional tribalism. Thus, intelligent people, who lean in the "EN" direction, are likely to espouse unusual, idealistic beliefs such as liberalism, multiculturalism, and egalitarianism. (As a matter of fact, the very word "idealistic" signals something contrary to what is evolutionarily familiar.)

- Vegetarianism: The idea of not eating animal protein is "unsual" in evolutionary terms, because it is contrary to ancient survival mechanisms. Thus, intelligent people, with their "EN" tendencies, are more likely to be vegetarians.

- Sexual Exclusivity: The idea of marriage and sexual exclusivity may be contrary to "natural" promiscuity (for men). Men who strongly uphold sexual exclusivity and monogamy may, in some respects, be unusual and have "EN" tendencies; thus, they are more likely to be intelligent.

There are many other conclusions and patterns noted in the book, a few of which are debatable, but most are very plausible and accurate. Despite Kanazawa's blunt and in-your-face writing style, his and similar books on evolutionary psychology are a welcome break from the sociological, liberal propaganda constantly shoved down people's throats in today's society. (By the way, this in itself is no coincidence: "Liberals control most institutions... because they are on average more intelligent than conservatives," Kanazawa notes: "Liberals control most organizations in most areas of life, even though the American population in general is mostly conservative.")

5.0 de un máximo de 5 estrellas The forces of the enforced ignorance are so strong these days that it is delightful to hear an independent voice. 20 de agosto de 2013

People who do the kind of research Kanazawa does often cannot get published. The get fired from their jobs at conservative as well as liberal think tanks. They have a hard time getting tenure at universities. There is little freedom of inquiry left in the realms in which Kanazawa works. For that reason alone it is delightful to see him publish such a politically incorrect work as this.

In his preface Kanazawa credits the giants who preceded him. Robert Trivers, Arthur Jensen, Philippe Rushton, just to name three. What I hoped in reading this book was to find a worthy successor to these, the latter two of whom died just last year. My hopes remain somewhat unfulfilled. While Kanazawa has the courage to beard any lion in its den, he has some shortcomings when it comes to structure and research.

The introduction to the book is a delight. It is a defense of academic freedom, the right of an academic, indeed, the obligation of an academic, to pursue the truth wherever it takes him. Quite specifically, this pursuit of truth should not be constrained by concerns about what the implications might be of the truths that are found. He talks about the great fallacies, the naturalistic fallacy and the moralistic fallacy. These are worth repeating right here in this this review, because they are so pervasive and academics today.

"The naturalistic fallacy, which was coined by the English philosopher George Edward Moore in the early 20th century, though first identified much earlier by the Scottish philosopher David Hume, is the leap from is to ought--that is, the tendency to believe that what is natural is good; that what is, ought to be. For example, one might commit the error of the naturalistic fallacy and say, "Because different groups of people are genetically different and endowed with different innate abilities and talents, they ought to be treated differently."

"The moralistic fallacy, coined by the Harvard microbiologist Bernard Davis in the 1970s, is the opposite of the naturalistic fallacy. It refers to the leap from ought to is, the claim that the way things ought to be is the way they are. This is the tendency to believe that what is good is natural; that what ought to be, is. For example, one might commit the error of the moralistic fallacy and say, "Because everybody ought to be treated equally, there are no innate genetic differences between groups of people." The science writer extraordinaire Matt Ridley calls it the reverse naturalistic fallacy."

The scientist cannot afford to be blinded by any of this. However, the frightening thing is that the vast number of them are. Read my review of "Race Decoded" for an example. Stephen Jay Gould's "Mismeasure of Man" is a classic example of a political screed masquerading as science. Its specious arguments still sway liberal-arts majors by the thousands.

Kanazawa depends vary greatly on statistical techniques, especially factor analysis. For a work that depends so heavily on statistics, he does very little to explain his statistical methods. He sometimes assumes that the reader knows nothing, and at others a great deal. On the nothing side, talking about intelligence distribution, he says that 5% of the population is very bright (IQ>125) and 20% bright (110-125). No statistical terms whatsoever. Elsewhere, however, he uses the statistical terms of mean and standard deviation, without a background as to how the latter is an expression of how the Gaussian distribution (bell curve) indicates how rare or common a given IQ score is. Here is the title of one of his graphs: "Figure 4.1 Partial association between lifetime number of sex partners and number of children among the less intelligent." The plot shows an upward slanting line amid a sea of dots. The index for children runs from -4 to 8; for sex partners from -100 to 300 (Wilt Chamberlain wasn't one of the dots.) A reasonable person might wonder how it is possible to have a negative number of either children or sex partners. It would help to provide said reasonable person with a discussion of "partialing out" variables in multiple linear regression. Without this help, the average reader will simply say, "Huh?"

Elsewhere, he sometimes normalizes his variables to a mean mean of zero and a standard deviation of one. That's well and good for statisticians, but he is writing a book with a real world audience. The topics he chooses, why homosexuals may be smarter than straight people, why and chosen people are not having children, are aimed to the general audience. He is expecting a higher level of understanding of statistics then he has any right to assume.

Kanazawa's intro says that "Most of the empirical analyses that are summarized in this book use three different data sets: General Social Surveys (GSS) in the US, National Longitudinal Study of Adolescent Health (Add Health) in the US, and the National Child Development Study (NCDS) in the UK." These are long term surveys. The GSS surveys 1500 people (3000 every other year) on a large number of topics. Add Health is a longitudinal survey - it follows 20,000 school children who were selected in 1994-95 through life. The NCDS follows all children born in Great Britain during one week in 1958 (17,000) through life. Each of the surveys includes an IQ component, or a good enough proxy for IQ to satisfy Kanazawa's purposes. As is usually the case in social science, he can be thankful to others' extensive labor in compiling what he got, but has to be mindful of the limitations. Each survey is constrained by the way the questions are worded and the questions that were asked. In each survey participants drop out in non-random ways. The surveys are culture-bound (US and UK) and bound in the case of longitudinal studies to late Baby Boomers (Great Britain) and late Gen X (United States). Societies change over time, and he has chosen cohorts each of which represents only one point on a time continuum. Most significantly, he generalizes from the US and UK to Europe, which might work, and to Asia, which probably does not. He could be accused of being influenced by the "streetlight effect," about which Wikipedia says "The streetlight effect is a type of observational bias where people only look for whatever they are searching by looking where it is easiest.

Surveys are by their nature are imperfect instruments. They generally ask the respondent to answer on a scale of 1 to 5 or 1 to 7, from "strongly agree" to "strongly disagree" or something similar. How the question is worded affects the answer. The respondent may be culturally inclined to avoid - or to take- extreme positions. Survey designers usually include several related questions, so they can compose aggregate answers which are more telling than the individual ones. Still, it is an imperfect art.

Kanawawa's overarching theme is that intelligence correlates highly with a love of novelty, and that our love of novelty often takes us in evolutionarily unsuccessful directions. It is pitched towards a fairly general audience - liberal arts majors. Therefore, the level of statistical understanding that he expects exceeds what can be expected of the type of audience he wants to attract.

The novel things he says we do include among other things homosexual practices, getting a university education, embrace the kinds of universal altruism represented by liberal dogmas, and using drugs and alcohol. To me the point seems a little bit of a stretch. I think that he is at least in part conflating trends which are taken place within American society, or all of Western society over the last century, with with his thesis of novelty.

Classic liberalism was not what we moderns would call liberal: more like libertarianism. The eugenics movement of a century ago was certainly what one would call conservative movement that was led by Victorian intellectuals. Fascism and communism were broad extensions of government, but certainly not consistent with modern liberalism. So to say that liberals are the ones who seek novelty, and are thus intelligent, is a somewhat shaky thesis. Novelty seekers have not always been liberal. An alternative thesis (America-Lite: How Imperial Academia Dismantled Our Culture (and Ushered In the Obamacrats)) would note that since liberals claimed control of the American campuses worldwide campuses about the 1960s and haven't let it go. Therefore everybody experiencing a university education in the West is brainwashed with an inordinate degree of liberal thought. The question is not why many of them turn out to be liberal, but how some of them manage to survive a college education these days and remain conservative. In other words, it should not attributed merely to the novelty of liberalism.

One observation I will make which Kanazawa should is that there are far more people of exceptional intelligence among North Asian populations than there are among Caucasians. Just by brute numbers, the Chinese and the Koreans and Japanese together number about time and a half the worldwide Caucasian population. As Kanazawa notes, they have a higher average intelligence. Put the two facts together, and the higher up you go in intelligence, 125 would be his cutoff, the greater the proportion of North Asians. By my rough statistics, about three times as many North Asians should have an IQ over 125 as Caucasians. In Excel, =1.5*(1-NORMDIST(125,105,15,TRUE))/(1-NORMDIST(125,100,15,TRUE)). Orientals don't display the same kind of liberalism, and they have a markedly different intellectual history than we do in the West. His thesis certainly should be tested against what's happening in the lands of his ancestors.

I found the book's treatment of homosexuality to be quite interesting. Kanazawa found some sources that I had not seen before, and his percentage attribution of homosexuality to genetics, environment in utero, and the environment in which a child grows up I found to be reasonably credible. He also had a useful four-way division of the definition of homosexuality. How people define themselves, what they do, their reports of the kind of erotic response they feel when exposed same-sex images, and objectively measured response to sexual stimuli. In other words not everybody's going to agree on who is a homosexual who is not. It's a question both of definite feelings and actions, and latent characteristics that may or may not be expressed. All that said, the differences he finds in intelligence between gays and straights seems to be seems to be fairly high. Again, one wonders what he would find in different societies.

One strength of his discussions about homosexuality is his reference to ethnographic literature citing homosexuality in 1500 societies around the world. Basically, it was not much noticed by anthropologists, and he defends the anthropologist's ability to notice these things. I would agree with them that homosexuality is much more evident today than it was even during my childhood 60 years ago. This may be a function of simply revealing latent traits that were there all along, but I suspected it also involves a greater element of choice than the homosexual community would like to admit.

The statistics he presents on the marked difference in intelligence between liberals and conservatives is quite surprising. I could believe this among white populations. Although he does not say which populations he is dealing with, his text reads as if he's talking about white people. However, although this book does not dwell on it, Kanazawa recognizes in his introduction that that black and Hispanic populations are significantly below the whites in average intelligence, and their voting is certainly what a modern would call liberal. Therefore if he is talking about all populations in the United States or in Western Europe, I would be suspicious of his case that liberals are more intelligent. Being conservative is contrary to the interests of less intelligent people. Nobody disputes that less intelligent people benefit more from government largess in government handouts, and most people are at least smart enough to vote their economic self-interest.

I conclude that at the top end of the intelligence distribution he is probably right. The collegiate liberals are people who feel they can be magnanimous with other people's money, and even some of their own. Father down the intelligence and income distribution I think he's got it wrong.

Kanazawa's treatment of religion seems to be quite simplistic. He says that the religious are less intelligent than atheists. I would quibble on several points. First of all, a great many people who claim not to believe in any identified religion cling religiously and without any intellectual curiosity to elements of their liberal dogma. Environmentalism is one of these things, vegetarianism, belief in holistic medicines, bottled water and the evils of circumcision - the list goes on. And they're adamant, as adamant as a fundamentalist with his rattlesnakes.

I pose a philosopher's question, what is religion? Another question would be about religion within cultures. Islam, Hasidic Judaism, and Christian fundamentalism are all quite different. The religion is part and parcel of the culture. I would bet that Mormons and Hasidic Jews are smarter than the average white person. So to generalize about religious belief I think glosses over some pretty important aspects of culture which are associated with religion. Simply to say that atheism is novel is nothing new. Again, there would be a lot to be gained by a discussion of North Asians. The Chinese and Japanese do not have religions in the same sense as people in the West. There is certainly no belief in the divinity of a person such as Christ or the status of a person such as Mohammed. There, religious leaders are regarded as teachers and seldom much more. So one follows the teachers, but one doesn't believe in their divinity. I would call them atheists. Any discussion of religion that doesn't include what the North Asians believe, is kind of off the track. One might well also include Indians, who have a vast number of beliefs, but are not points of belief in divinity in the same way that Christians Jews and Muslims, people of the book, believe in their God.

Certainly more intelligent people led the drug revolution in the US in the `60s. I was there - Berkeley. However, I note that where I now live in Ukraine, the 20-somethings from the top universities with whom I associate have no experience with drugs. Here, as in Brazilian favelas, it is the dead-enders in the lower rungs of society who do drugs. They sniff glue and do needle drugs. For them it is not novelty - it is culture.

As far as sexual experimentation goes, that too changes quite rapidly. I witnessed it go from quite prudish in the `50s, when knocking a girl up was a disaster, to very loose during the sexual revolution of the 60s, to increasingly guarded, first when herpes became widespread, then AIDS. Culture also played a part, especially changing, unpredictable feminist notions of what they wanted men to be. Whether and how a guy got sex changed like lady's fashions - because it was in part a fashion concern. The novel thing is the swiftness with which it changes - for everybody.

In conclusion, I would like to say that what this field of evolutionary biology needs is more people like Kanazawa. Specifically, Kanazawa needs more people against whom he can bounce his ideas. A lot of these ideas are kind of off the wall. They would have benefited by being polished by a larger number of associates with similar views. Unfortunately, the academy the universities absolutely discourage people think and talk about these subjects, and therefore the number who are bold enough to work in this field is quite limited. Kanazawa must feel like he is the last of the Mohicans, the Lone Ranger. I hope his bravado inspires others to stand up against the tyranny of political correctness and join him in doing real science. He has put forth ideas which merit deeper study. Hope somebody rises to the challenge, and helps Kanazawa polish his theses.

Written from the perspective of an evolutionary psychologist, this is an interesting and accessible book regarding what is valuable about high intelligence and what is not. In a nutshell, intelligence is an asset when we face novel situations, but can lead to clever boneheadedness in everyday life. Kanazawa shows little patience for political correctness when it conflicts with what he sees as the evidence, and this is likely to irk some readers. However, he does present his case cogently, and is an entertaining read, whether he ultimately convinces or not.

To understand this book, we need to understand the terms that are being put out by it's author.

General Intelligence is the term that defines those that have a High I.Q.

Evolutionary Novel deals with things that are new to humans. Computers and other things.

Evolutionary familiar deals with things that humans are naturally good at. Finding mates, being good parents, etc.

The Savannah principle deals with things relating to the ancestral environment. What was true in the period of our ancestors is true now.

The intelligence Paradox is why people with general intelligence tend to go against the grain of what human beings are genetically prone to doing.

Smart is not the same as intelligent. Smart is the evolutionary familiar thing to do while evolutionary novel is the intelligent thing. Hence the title.

Hitherto, we can understand the entire book and how it all relates to one another.

People with above average intelligence will be good at things that are evolutionary novel concepts and those with average or below will be good with evolutionary familiar concepts. Granted there are exceptions to everything.

Starting from the beginning, we are treated to definitions of the above as well as a stating of the problem that is trying to be solved. Which is, why intelligent people seem to do "Stupid" things.

Stupid is defined as doing things that are not evolutionary familiar.

We get a run through of common misconceptions regarding intelligence and the various test used to measure such.

He gives us a run down of a 2002 study in which people with above average intelligence tend not to like television as opposed to people with below average intelligence. Simply put, our only interactions with other humans back in the day was real contact. Thus our brains cannot understand the evolutionary novel concept of television. You may understand how T.V. works but your brain doesn't. Which is why less intelligent people tend to enjoy T.V. more. Not only can they suspend disbelief but they get the same reaction as if they where hanging out with real people. Even going so far as to report more satisfaction with friendships. Granted, there are intelligent people who can enjoy T.V. as well but they do not essentially report greater satisfaction with friendships or anything else. The author specially mentions television when referencing this. Although a couple of analogies deal with movies, television is referenced more often.

This holds true with pornography as well. Less intelligent men will think every woman is promiscuous and enjoy sexual acts like fellatio. Basically, anything that isn't straight sex.

That said, we then get several chapters of things that are evolutionary novel and why intelligent people are more likely to be prone to engage in them.

1. Liberals are more intelligent then conservatives. Keep in mind, Liberal is defined as anyone who generally cares for the well being of non-genetically related individuals. If you have ever read The Selfish Gene by Richard Dawkins, this should make perfect sense. We are designed to take care of our own. This increases reproductive success. Which is the goal of all animal species. Yet on average, more intelligent people care about the well being of others. This is evolutionary novel.

2.The second deals with Atheist being more intelligent that the religious. Religion may be evolutionary familiar domain. (Enjoy the irony to that one.) This chapter deals with Type one and two inferences. Type one inferences are to think when something random occurs, it could actually be something. Predator or other. Paranoia ensues. This is evolutionary programmed into people so that they don't get killed. The author likens it to smoke alarms. They are designed to be ultra sensitive. Making a type one inference is better because it increase the chance of survival. Type two inferences, passing it off, leads to death. Thus on average, less intelligent individuals might be more prone to making type one inferences rather than type two. Basically, type two is rational thinking versus type one which is not.

3. Why more intelligent men (but not woman) value sexual exclusivity.

Male humans are designed to copulate with everything that moves. The more you have sex, the higher the chance to sire progeny and pass your genes on. This is the ultimate goal of all species. Yet, more intelligent men value sexual exclusivity than the less intelligent ones. The female of the species always have options to pick since they bear the cost of reproduction more than men. Men with more general intelligence are apt to go further in life than their less intelligent counterparts. As such, more intelligent men have more resources.

The opposite is true of more intelligent woman. They tend to be more promiscuous rather than valuing of monogamy and this is because woman are designed to chase after resources. More intelligent men have more resources then their less intelligent counterparts, so it is better to have smaller claim in a worthwhile man rather than having full stake in worthless man.

Income inequity also leads to a more polygamous society.

More intelligent men might be prone to extra-martial affairs over less intelligent men.

4. Why more intelligent individuals are night owls.

All animals have Cardin rhythms. This is our biological clock. In the ancestral environment we didn't have cars or street lights. We had fire, stars and an inability to see in the dark. So why do more intelligent individuals stay up when our natural pattern should be to rise in the morning and go to sleep at dusk to avoid predators like our ancestors did? Again, staying up late is evolutionary novel. As such, more intelligent people are likely to be up at night.

5. Why homosexuals are more intelligent that heterosexuals.

Homosexuality is found in nature but not exclusive homosexuality. In the game of life, the ultimate goal is reproduction. So why are people exclusively homosexual? While a gene for homosexuality has yet to be discovered, geneticist are finding that that homosexuality and intelligence may be linked to the same gene. Again, homosexuality might be an evolutionary novel concept.

6. Why more intelligent people like classical music.

Classic musical is thought to be a Evolutionary novel concept because it is complex and all instrumental. Whereas music as always involved singing. Thus pure instrumental music is a newer concept. That makes it evolutionary novel concept.

7.why intelligent people drink and smoke more.

Again, as you have no doubt deduced by now. Smoking and drinking are evolutionary novel concepts. Go figure as much, right? This is the running thread through them all.

Finally the author concludes that the real losers in life are intelligent people. Granted this is only if you see losing as not being a great lover, parent or friend. I think I'd rather be a brilliant theoretical physicist than to be a Casanova in bed but that is just me.

A fine and well written book. Worth buying and reading if you are interested in intelligence and what it is and isn't.

1.0 de un máximo de 5 estrellas A Stupid Book Pretending to be Intelligent 28 de junio de 2012
Por Frank N. Wiley - Publicado en
Formato: Tapa dura
In "The Intelligence Paradox", Satoshi Kanazawa says that intelligent people do and say stupid things. Chief among these have to be most of the claims that Kanazawa makes in his own book. Not only are they stupid - they're incredibly irresponsible. In an era of overpopulation and the dumbing down of Western civilization, his message appears to be: don't bother with education, have as many babies as possible!

Kanazawa commits many fallacies in his book, chief of which is confusing potential with actual performance. On page 36, his subtitle says: Sorry, education does not increase your intelligence. What he overlooks is that IQ is a measure of potential, not actuality. It is like talent in music. As research shows, the greatest pianists are not necessarily the most talented, but the ones who practice the most; in fact those that practice more than 10,000 hours. Education is to those with high IQ what practice is to musical prodigies - the realization of potential - and it surely takes as many hours to realize that potential fully.

Next, he commits the fallacy of over-generalization. Several times, he comments on how intelligence is just one human characteristic among many, yet somehow it has become inflated to be a key determinant of a person's worth. He then compares it to two other characteristics: "taller people are different from shorter people, and sociable people are different from unsociable people. But we never equate any of those individual traits with human worth." Is he kidding?? Numerous studies show that taller people are invariably assumed to be better - smarter, more competent, better teachers, etc. And height and sociability are two key factors in Kanazawa's area of expertise: evolutionary psychology. They are among the most important traits that determine reproductive success.

Finally, he commits the naturalistic fallacy - confusing "is" for "ought". This is Kanazawa's most egregious error, since on page 19 he warns how important it is that we avoid this fallacy. Yet, in his final chapter, he notes that reproductive success is what all humans are evolutionarily designed to do. That's the "is." He then goes on to the "ought" - in which reproductive success is "the meaning of life itself." He emphasizes this point on page 206, where he states that general intelligence may make for better physicians, astronauts, scientists and violinists, but that "these are all unimportant things in life." Sorry, Isaac Newton. You may have launched the Scientific Revolution and changed the entire world, but the fact that you had no children apparently makes your life meaningless! If that's truly the case, then other meaningless lives include Descartes, Locke, Pascal, Spinoza, Kant, Leibniz, Schopenhauer, Nietzsche, Kierkegaard and Wittgenstein.

In the end, I could not fathom what Kanazawa is trying to say. An associate editor of "The Journal of Social, Evolutionary, and Cultural Psychology" as well as a reader at the London School of Economics and Political Science, he obviously hopes to educate people. But why, if education makes no difference in intelligence?

And if intelligent people do such stupid things, why bemoan the fact (as he does at such great length) that intelligent women are having less babies? Isn't that a good thing? Won't we be better off with a world that's filled with less intelligent people who are somehow "smarter"?

Kanazawa's major claim is that general intelligence is only good for things that are evolutionarily novel. Well, that "only" includes ALL of human civilization!! While the last 10,000 years may not have changed our Pleistocene instincts, I'd say that they've had a rather significant impact on human life. I for one am grateful to live in the world that has grown out of human intelligence, and I think we should do everything possible to lionize and enhance it. Kanazawa unfortunately has joined a long list of authors who seem to take great pleasure in denigrating that which makes us unique. In my opinion, that's just stupid.

If you're looking for a book that reveals the true power of intelligence, read Charles A. Murray's "Human Accomplishment" instead.
