Här nedan kommer ett vetenskapligt, empiriskt bevis för den könsmässiga diskrimineringen som pojkar utsätts för i svenska skolan.
Beviset är enkelt: mäns IQ är alltjämt högre än kvinnors, trots hundra års försök att göra testet könsneutralt. Samtidigt är betygsskillnaderna i svensk skola jättestora. Skall det vara så, att om man föds till pojke, så får man sämre möjlighet att söka till den utbildning man vill på gymnasiet och högskolan?
According to the 1994 report ”Intelligence: Knowns and Unknowns” by the American Psychological Association, ”Most standard tests of intelligence have been constructed so that there are no overall score differences between females and males.” Differences have been found, however, in specific areas such as mathematics and verbal measures.
When standardized IQ tests were first developed in the early 20th century, girls typically scored higher than boys until age 14, at which time the curve for girls dropped below that for boys. As testing methodology was revised, efforts were made to equalize gender performance.
The mean IQ scores between men and women vary little.
Several meta-studies by Richard Lynn between 1994 and 2005 found mean IQ of men exceeding that of women by a range of 3-5 points. Lynn’s findings were debated in a series of articles for Nature. Jackson and Rushton found males aged 17–18 years had average of 3.63 IQ points in excess of their female equivalents. A 2005 study by Helmuth Nyborg found an average advantage for males of 3.8 IQ points. One study concluded that after controlling for sociodemographic and health variables, ”gender differences tended to disappear on tests for which there was a male advantage and to magnify on tests for which there was a female advantage.” A study from 2007 found a 2-4 IQ point advantage for females in later life. One study investigated the differences in IQ between the sexes in relation to age, finding that girls do better at younger ages but that their performance declines relative to boys with age. Colom et al. (2002) found 3.16 higher IQ points for males but no difference on the general intelligence factor (g) and therefore explained the differences as due to non-g factors such as specific group factors and test specificity. A study conducted by James Flynn and Lilia Rossi-Case (2011) found that men and women achieved roughly equal IQ scores on Raven’s Progressive Matrices after reviewing recent standardization samples in five modernized nations. Irwing (2012) found a 3 point IQ advantage for males in g from subjects aged 16–89 in the United States. [Wikipedia]
