What is intelligence?

What is intelligence?

What is intelligence? Let us count the ways. Actually, the many definitions you’ll find below are merely the tip of the iceberg. I have listed my sources at the end of this post.

“I’ve become more aware of and impressed by how much of leadership is about emotional intelligence. The more you lead, the more you understand how much of it is about motivation – and motivation is about emotions…To lead, being smart isn’t sufficient. You have to connect with people so that they want to help you move the organization forward.”

Robert Joss, Dean of Stanford University’s Business School.

“Knowing a great deal is not the same as being smart; intelligence is not information alone but also judgment, the manner in which information is collected and used.”

Carl Sagan

“I not only use all the brains that I have, but all that I can borrow.”

Woodrow Wilson

“It’s not that I’m so smart, it’s just that I stay with problems longer”

Albert Einstein

“Continuous effort - not strength or intelligence - is the key to unlocking our potential.”

Winston Churchill

“Intelligence is the ability to adapt to change.”

Stephen Hawking

“The capacity to acquire and apply knowledge, especially toward a purposeful goal.”

dictionary.com

“We define emotional intelligence as the subset of social intelligence that involves the ability to monitor one’s own and others’ feelings and emotions, to discriminate among them and to use this information to guide one’s thinking and actions.”

Salovey & Mayer, Emotional Intelligence (1990)

“Does a president need to be smarter than his advisors? The key is how to define ‘smart.’ A president can hardly be more expert than, in sum, a collection of advisors…”

Ron Suskind, The Price of Loyalty

“Much evidence testifies that people who are emotionally adept — who know and manage their own feelings well, and who read and deal effectively with other people’s feelings — are at an advantage in any domain of life, whether romance and intimate relationships or picking up the unspoken rules that govern success in organizational politics.”

Daniel Goleman

“Intelligence is solving a problem or creating a product that is valued in society.”

Intelligence as a display of healthy sperm

Psychologists found a strong correlation between high IQ and healthy sperm, as reported by the U.K. Telegraph:

The research, by the evolutionary psychologist Professor Geoffrey Miller of the University of New Mexico, centred around a study of 400 Vietnam War veterans who were put through extensive mental tests and were also asked to provide sperm samples. According to the test results, it was found that men who scored high on a battery of intelligence tests boasted high counts of healthy sperm. Whereas, low scorers tended to have fewer and more sickly sperm.

Miller points out that intelligence is sexually attractive to both sexes, and that intelligence co-evolved with sperm quality to advertise good genes.

The correlation between religiosity and intelligence.

Gad Saad of Psychology Today reports that really smart people tend to not be religous. I know that this topic is going to stir up a lot of emotion, but it is quite clear that our smartest scientists tend to not follow religions. Not that there aren’t lots of blisteringly smart believers out there, some of them first-rate scientists. The trend says that Nobel Prizes mostly go non-believers.

Richard Nisbett: Intelligence mostly varies due to the environment, not genes

The dominant hereditarian view of intelligence holds that intelligence is mostly fixed by the genes. Richard Nisbett has dismantled the evidence on which the hereditarian theory is based. In his new book, Intelligence and How to Get It, Nesbitt argues that the twin studies on which the hereditarian view is based are deeply flawed. The main problem is that the adoptive homes in which those separated twins often find themselves are uniformly enriched learning environments. Nisbett’s book was reviewed by Jim Holt of the NYT Book Review:

Nisbett bridles at the hereditarian claim that I.Q. is 75 to 85 percent heritable; the real figure, he thinks, is less than 50 percent. Estimates come from comparing the I.Q.’s of blood relatives — identical twins, fraternal twins, siblings — growing up in different adoptive families. But there is a snare here. As Nisbett observes, “adoptive families, like Tolstoy’s happy families, are all alike.” Not only are they more affluent than average, they also tend to give children lots of cognitive stimulation. Thus data from them yield erroneously high estimates of I.Q. heritability. (Think: if we all grew up in exactly the same environment, I.Q. differences would appear to be 100 percent genetic.) This underscores an important point: there is no fixed value for heritability. The notion makes sense only relative to a population. Heritability of I.Q. is higher for upper-class families than for lower-class families, because lower-class families provide a wider range of cognitive environments, from terrible to pretty good.

What does Nisbett’s book have to say about race and intelligence? That the differences among the “races” are not genetic. Evidence in point: The “racial” IQ gap has been shrinking. “Over the last 30 years, the measured I.Q. difference between black and white 12-year-olds has dropped from 15 points to 9.5 points.”

Intelligence versus attractiveness; is there a correlation?

Intriguing post by Satoshi Kanazawa at Psychology Today. He points out research that purports to show that intelligence correlates positively with attractiveness.

This research does dispel the notion that very attractive woman are less intelligent than average-looking woman; according to this research, very attractive woman are in the most intelligent group. I’m mulling over these findings; I don’t quite know what to think of this yet. I do know that I’m highly suspicious of any sort of simplistic IQ-based characterization of “intelligence” (I recently made that point here).

Kanazawa began this post pointing out the rampant prejudice that attractive people are more intelligent, but then argues that “virtually all stereotypes are empirically true.” I suspect that there is some truth driving many stereotypes, but I think his conclusion (that “virturally all stereotypes are empirically true”) is dangerous in its vagueness. Social feedback loops can cause stereotypes come true; if we mistreat people from stigmatized social groups, this makes it more likely that they will not do as well as social groups that have no such disadvantages. And even if it were true that there is some overall basis for most stereotypes, this doesn’t begin to suggest that we ought to make presumptions about any particular individuals.

Should science study race and IQ?
By Erich Vieth on March 06th, 2009

Should science study race and IQ?

Should science study race and IQ? A recent article in Nature (”Should scientists study race and IQ“) says yes, as long as the research is done carefully and kept free of outside influence and premature application by social scientists and politicians. Science did not give rise to bigotry. After all, scientific studies of race and IQ began in relatively modern times, only after long centuries of “pernicious folk-theories of racial and gender inferiority predated scientific studies.” The authors believe that first-rate scientific research will, in the end, dispel much of the racial bigotry that still exists.

Some scientists hold more ‘acceptable’ views, ourselves included. We think racial and gender differences in IQ are not innate but instead reflect environmental challenges. Although we endorse this view, plenty of scholars remain unpersuaded. Whereas our ‘politically correct’ work garners us praise, speaking invitations and book contracts, challengers are demeaned, ostracized and occasionally threatened with tenure revocation.

Acts of censure edge close to Lysenkoism. They also do a disservice to science. When dissenters’ positions are prevented exposure in high-impact journals and excluded from conferences, the dominant side goes unchallenged, and eventually its rationale is forgotten, forestalling the evolution of crucial ideas.

I am sympathetic to the need to for scientists to carefully examine everything, no exceptions. I’m concerned, though, that we need to look extra-closely at the concept of “race,” which I consider to be virtually useless in daily matters. Nor should we allow the simplistic concept of “IQ” to serve as a variable, given much more expansive ways to measure intelligence (see, for example this post on Howard Gardner’s work). For more on the dangers of misusing “IQ,” see Steven J. Gould’s 1996 book, “The Mismeasure of Man.”

In sum, we should do good science and I believe that good science would suffocate bigotry. The article points out several examples of this. Good science should be done on only after kicking out the clumsy, pernicious concepts of “race” and “IQ,” reframing the debate as the relationship between fine-grained genotypic variation and competence in each of the many ways in which humans display competence. Because genotypic variation within “races” is at least as wide as genotypic variation among “races,” a meaningful scientific exploration would not amount to a simplistic survey of how people with different colors of skin do on standardized intelligence tests. That would not be good science. Good science will always take into account the convoluted ever-changing environment, and that is not easy to do when we are dealing with basic concepts that are vague.

I’m not convinced that we are prepared to begin the necessary research on this general topic, because too many of us, including many well-trained scientists, have not done their ontological homework (consider the incoherent and clumsy stumblings of DNA co-discoverer James Watson, described in the article). Are “race” and “IQ” useful constructs with which to do this sort of research? Time will tell if we are intelligent enough to sharpen our constructs before running off to demonstrate our “truths.”

Just how stupid are Americans?

About some things, Americans are incredibly stupid. For instance, I’ve kept an eye on science and religion related ignorance for years. 15% of Americans don’t know that the Earth revolves around the sun. Half of the people in the United States (an allegedly “Christian Nation”)  can’t name Genesis as the first [...]

Intelligent Crows

Chimpanzees aren’t the only spectacularly intelligent animal species.  Sometimes human beings act intelligently!  Yes, humans are animals, as difficult as this is to believe for many people.

In this TED video, Joshua Klein reminds us about the intelligence of yet another species: crows.  Using their  intelligence, crows continue to flourish among human populations.
