"one key difference between kids who excel at math and those who don't"

"Psychologists Lisa Blackwell, Kali Trzesniewski, and Carol Dweck [found that] convincing students that they could make themselves smarter by hard work led them to work harder and get higher grades. The intervention had the biggest effect for students who started out believing intelligence was genetic."

IQ and Marijuana

A study published last year shows that teenage marijuana use can lead to decreased IQ in adulthood. According to Nature, "when their adult IQ was tested at 38 years old, the heaviest and most persistent adolescent-onset users in the study had experienced an average decline of eight IQ points from childhood to adulthood."

IQ and the Nativist Movement

Jason Richwine has resigned from the Heritage Foundation. Richwine is the author of a the Heritage report, "The Fiscal Cost of Unlawful Immigrants and Amnesty to the U.S. Taxpayer." In 2009, Richwine earned his doctorate from Harvard University, and his dissertation was titled "IQ and Immigration Policy", which argued that Hispanic immigrants have lower IQ than white native immigrants.

Intelligence Tests

Is Psychometric g a Myth? - "As an online discussion about IQ or general intelligence grows longer, the probability of someone linking to statistician Cosma Shalizi's essay g, a Statistical Myth approaches 1. Usually the link is accompanied by an assertion to the effect that Shalizi offers a definitive refutation of the concept of general mental ability, or psychometric g." [more inside]

My IQ

When I came to the US, I heard about Mensa — the high IQ society. My IQ had never been tested, so I was curious. I was told that there was a special IQ test for non-English speakers and that my fresh immigrant status and lack of English knowledge was not a problem. I signed up.

Modern Thinking

New Republic article on James Flynn's new book Are We Getting Smarter?: Rising IQ in the Twenty-First Century "IN THE MID-’80s, the political philosopher James Flynn noticed a remarkable but puzzling trend: for the past century, average IQ scores in every industrialized nation have been steadily rising. And not just a little: nearly three points every decade. Every several years, IQ tests test have to be “re-normed” so that the average remains 100. This means that a person who scored 100 a century ago would score 70 today; a person who tested as average a century ago would today be declared mentally retarded." [more inside]

Adjusting the Bar to Hire Outsiders

Chinese Outsourcer Seeks U.S. Workers With IQ of 125 and Up. "A Chinese IT outsourcing company that has started hiring new U.S. computer science graduates to work in Shanghai requires prospective job candidates to demonstrate an IQ of 125 or above on a test it administers to sort out job applicants. In doing so, Bleum Inc. is following a hiring practice it applies to college recruits in China. But a new Chinese college graduate must score an IQ of 140 on the company's test. An IQ test is the first screen for any U.S. or Chinese applicant."

Parasites wreck the brain?

Parasites may affect brain function: Toxoplasmosis is a famous example. Now researchers have proposed that country-by-country differences in IQ can be explained, in part, by parasite burden.

Two men with big hair and the nature of IQ

Behind the growing Steven Pinker vs. Malcolm Gladwell feud (Pinker criticizes Gladwell, Gladwell snarkily replies) is a debate over the value of IQ, specifically, and intelligence, broadly, in success. Recent research has generally shown little link between intelligence and success within fields, and that there are multiple kinds of intelligences that drive achievement. On the other hand, scholars of psychometrics claim the opposite, showing that IQ at an early age can predict achievement, and no amount of study will help. Maybe everyone is right, with enough caveats.

Islam, modernity and democracy

Is the west thwarting Arab plans for reform? Few Muslims now invest much hope in the democratic western powers (essentially the US, Britain and France) that back the rulers who oppress them, even if, against the odds, they still admire “western” values, science and culture. There is no endemic or intrinsic conflict between Christians and Muslims. Rather, the root of the problem is that a majority of Muslims is convinced that the west – interested only in a stability based on regional strongmen, the security of Israel and cheap oil – is engaged in a war against Islam and is bent on denying them the freedoms it claims for itself. That is why it is so self-defeating to collude in tyranny as ostensibly a lesser evil than political Islam. [more inside]

Race and Intelligence, Redux

About a month ago, a MeFi FPP on this article sparked a controversy here on the usefulness of the concepts of IQ and race in determining whether some ethnic groups can be shown to be intrinsically less intelligent than others. Now James Flynn, discoverer of the Flynn effect, has written a book, What is Intelligence?, that settles many of the issues of this controversy. In this week's New Yorker, Malcolm Gladwell summarizes Flynn's arguments succinctly in a review entitled "None of the Above: What IQ doesn't tell you about race."

Race and Intelligence

Among white Americans, the average IQ, as of a decade or so ago, was 103. Among Asian-Americans, it was 106. Among Jewish Americans, it was 113. Among Latino Americans, it was 89. Among African-Americans, it was 85. Was Watson right?

Dr Kanazawa.

I find my interest piqued by some of Dr Satoshi Kanazawa's ideas. Especially regarding The conformist culture of Asia. But also: The Myth of Racial Discrimination in Pay in the United States[pdf]. He works hard thinking.

smart_women != married_women; smart_men == married_men

A high IQ is a hindrance for women wanting to get married while it is an asset for men, according to a study by four British universities.

The study found the likelihood of marriage increased by 35 per cent for boys for each 16 point increase in IQ. But for girls, there is a 40 per cent drop for each 16-point rise, according to the survey by the universities of Aberdeen, Bristol, Edinburgh and Glasgow. The study is based on the IQs of 900 men and women between their 10th and 40th birthdays. (via)

Check out the big brains on these guys!

Human Intelligence is a good site from Indiana University that looks at historical influences and current controversies surrounding the study of intelligence. Find out more about topics such as "the Mozart Effect", the theory of multiple intelligences, and the influence of birth order on intelligence, and then browse the brains behind the history of inquiry into human intellect.

It's the IQ, stupid

"Innate intelligence has to do with capability and ignorance to do with variables such as educational opportunity and personal diligence. But the conundrum remains. Is intellect important in presidents? If Americans can't solve the question definitively in the matter of John Kerry and George Bush, we damn sure ought to make an educated guess."

Big brains, crap design skills.

Giga Society: the world's most exclusive high IQ society, where an IQ of 196 or higher (one in a billion) is required to join. Not quite as cranially-advantaged? Well, there's always the Oath society, which'll take you if you're only one in a thousand (a mere 150 IQ or higher). Big brains and design skills (or language ones, for that matter) don't mix well, though, it would seem. [more inside]

Money makes you stupid

The more you earn, the lower your IQ. That's the clear but unexpected result from the second National IQ test broadcast by the BBC. The test is still online if you are curious. The first test was discussed here. For a higher IQ, be an unemployed Irish man and drink too much.

International High IQ Society tests

International High IQ Society tests. The site gives the impression that these tests are a lot more accurate at judging intelligence (whatever that is) that most of the junk on the web. What do you think? Do we have any 'universal geniuses'?

How smart are you? Are blondes really as dumb as people say? Does an IQ test administered via television/net/SMS have any validity anyway?

Musicians are really smart. They have larger and more sensitive brains than non-musicians, and their collective IQ is much higher. They have 130% more grey matter in one area of their auditory cortexes. The question of how this explains Ozzy Osbourne nonwithstanding, I'll bet if you're really, really smart, you could be one of the new members of Men Without Hats. Must be very knowledgeable in midi, sequences, and sampling.

Test the Nation

Last night, ninety-five thousand British Internet users took part in 'Test The Nation', an IQ quiz, broadcast live on BBC television, which attempted to survey the intelligence on the national. As a simulcast it was only partially successful -- the questions appearing on television sometimes five minutes before appearing on computer, but the results from those who coped with the technology were quite interesting. Any other UK Mefites take part? The test is still available for the curious.

Rejection reduces IQ

Rejection reduces IQ "To live in society, people have to have an inner mechanism that regulates their behaviour. Rejection defeats the purpose of this, and people become impulsive and self-destructive. You have to use self-control to analyse a problem in an IQ test, for example - and instead, you behave impulsively"

Take the Wonderlic test.

Take the Wonderlic test. The Wonderlic is a 50-question IQ test administered by the National Football League to all prospective draft picks. Teams use the test results to varying degree, in part to determine the ability of athletes to learn systems and grow as a player. Interestingly, offensive tackles and centers have the highest average NFL Wonderlic scores. (The test here is a fast 15-question sample; you'll need a piece of paper to jot down your answers.)

Is intelligence hereditary or environment? A new theory sees the brain as a plastic mold of potential with the more neuron connections the better [hereditary] and environment stimulation shapes the mold untill maturity. "You could present a person with an IQ of 200 with the appropriate phenomena when they are 20 years old, after the critical learning period, and they would not have the capacity to adapt their brains to the new phenomena". People of low IQ perform poorly because their brains do not adapt well to environmental stimulation.

Breast-feeding increases babies' IQ

Breast-feeding increases babies' IQ by 3-5 points, compared to the babies fed with formula. This is probably for two reasons: better nutrition and maternal bonding. Premature babies receive the greatest benefits.

higher IQ = longer life span

higher IQ = longer life span
A study in the British Medical Journal shows a link between IQ and longevity. 2200 children were tracked from childhood to the age of 76. A 15-point disadvantage in IQ meant the child was only 79% as likely to be alive at 76. A 30-point disadvantage reduced the odds to 63%. *link found at darwin awards

Kids are smarter than ever before,

Kids are smarter than ever before, AOL chat transcripts notwithstanding. It seems to me that the fact that IQ tests measure culture acquisition as much as anything else may explain a lot of this, but I wonder if there may not be something to the "visual literacy" idea: are we (as a species) building a new type of perception, or honing old cognitive tools into something which might as well be new? And, if so, where might it lead us?
