-'''Intelligence testing''' began in an organized way in the early 20th Century with the [[Stanford-Binet]] test. The purpose was to form an estimate of a person's aptitude before investing time and money in their education, in the belief that aptitude or intelligence was a fixed quantity.
+Imperial25 was here.
-At the time these tests were developed, medical science and psychology were
-in their infancy. Ideas such as [[eugenics]] still had currency, and intelligence tests were used to weed out so-called "defectives".
-Testers classified people as idiots, imbeciles, morons, normal, above average, and geniuses on a numerical scale based on [[mental age]]. For children, dividing the mental age by chronological age produces the [[intelligence quotient]] (IQ) used for placement in slow or rapid classes.

-In the United States, intelligence tests were to classify recruits and draftees for service in World War II. The more technical jobs were assigned to men with higher scores. Sociologists also noted racial differences in IQ scores, and some supposed that these differences were inherent. A controversy over this matter has raged ever since.
-Open questions for psychologists and sociologists focus on what produces differences in [[intelligence]], whether intelligence can be developed or stunted by upbringing and education, and why different [[race]]s or cultural groups have significantly different scores.
-The two main reasons given are:
-#that there may be inherent differences between the races
-#that upbringing, education and social factors can skew the results
-After nearly a century of IQ testing and [[educational reform]]s, some researchers have begun to assert that IQ can be influenced by the child's environment by as much as 30 points.<ref>3 weeks of intensive play of WFF 'N PROOF: The Game of Modern Logic increased average IQ scores by more than 20 points. [http://wffnproof.com/] </ref> See [[Educational games]].

-The field of intelligence testing has been acrimonious and contentious. Researchers such as [[Arthur Jensen]] and [[Charles Murray]] have been pilloried in the mass media, accused of maintaining views which different or even opposite of their actual views. <ref>Evolution advocate Gould portrays Murray as saying intelligence can be measured with a single number; Murray, of course, makes it clear in his book (as well as in a follow-up retort to Gould) that intelligence is too complex to be measured with a single number. </ref>
-One professor had to come to Jensen's defense, after [[Stephen Jay Gould]] attacked him in print:
-:I object to Gould's tendency to visit the alleged sins of early investigators on present day investigators. If Goddard, Brigham, and others once tended to view various human races as relatively superior or inferior in intelligence and therefore relatively worthy or unworthy, this does not mean that present-day investigators, like Jensen (1980) or Rushton (1995), are necessarily guilty of such views. In fact, from my personal acquaintance with Jensen and his publications, I can attest that he does not view the African race (if one accepts that it is a race) as in any way less worthy than other so-called races.

-[[Charles Murray]] said:
-*As soon as anyone argues that racial differences in intelligence are authentic, not an artifact of biased tests, everyone decodes that as saying the differences are grounded in genes. It is a non-sequitur, but an invariable one in my experience. America's intellectual elites are hysterical about the possibility of black - white genetic differences in IQ.
-*As you know, The Bell Curve actually took a mild, agnostic stand on the subject. Dick Herrnstein and I said that nobody yet knows what the mix between environmental and genetic causes might be, and it makes no practical difference anyway. The only policy implication of the black - white difference, whatever its sources, is that the U.S. should return forthwith to its old ideal of treating people as individuals.
-*But how many people know this? No one who hasn't read the book. Everyone went nuts about genes, so much so that most people now believe that race and genes is the main topic of our book. [http://www.eugenics.net/papers/mssel.html]
-The Bell Curve book is not the only controversial study on IQ among different races or groups of people. Danish professor [[Helmuth Nyborg]] has conducted studies of IQ which indicate [[Politically correct language|politically incorrect]] results such as: on average, white people have higher IQs than black people, and men have higher IQs than women. His latest research finds that on average, [[atheists]] have IQs about 5.8 points higher than people of [[faith]], prompting similar outrage among his critics, who claim that such results might be due to cultural biases.[http://danish.newsvine.com/_news/2007/02/05/554043-professor-atheists-are-more-intelligent-than-believers]
