Size Does Matter: Men Beat Women In Iq Because Of

Size does matter: men beat women in IQ because of their bigger brains

The men would be 3.75 points above, a difference that another Spanish investigation branded as “invaluable”.

“He says that he does not need to consult with anyone about his foreign policy, that he has a great brain for that. I say that statement is debatable.” who was speaking Barack Obama in reference to Donald Trump weeks before the biggest disappointment of his career in the US elections. A study of la Erasmus University de Rotterdam gives him the finishing touch: Trump, always concerned about questions of size, can not only boast of the volume of your brain mass, but this would have given him a head start about your opponent Hillary Clinton.

Imputing a lower intelligence to women based on the morphological criterion of having a smaller brain was for centuries a ruse to support sexist prejudices. The advent of standardized measures such as the I.Q It was banishing these discriminatory apriorisms throughout the 20th century. However, the difference exists. A study of University of Edinburgh published in BioRxiv described a thicker cortex for them versus a larger volume of the subcortical structures (hippocampus, thalamus or amygdala) for them.

Likewise, monitoring the activities of the different regions of the brain reveals best faculties in the feminine in the areas of language and recognition, while the masculine excels in spatial orientation and calculation. Hence the neurological basis of the tagline about men who are capable of reading a map but not of asking when they are lost. The study led by Dimitri Van der Linden however, he again put the accent on the controversial theory of an alleged gender disparity in general intelligence (g).

The study selected a thousand men and women between the ages of 22 and 37. Through magnetic resonance imaging, the measurement of his brain was obtained, understood as your total volume of gray and white matter. The result was approximately a liter for women for 1.2 for men. They were then subjected to a range of cognitive tests to cover different capacities: memory, calculation, vocabulary, processing speed and recognition.

The subjects with larger brains performed better. The researchers then separated them by sex, and again into two groups: the largest brains for their gender median in front of the little ones. The first group proved to perform better than the second in both men and women. But the male brain, having a greater relative volume regardless of the size of the individual, gave the advantage to men.

The greater female cortical thickness was not shown to compensate for women; neither the result of the tests focused on their greater linguistic ability. Van der Linden came to quantify in 3.75 points superiority in qualifications. “If men had an IQ of 100, women’s would be 96.” – declared to The Times.

Contradicts the Spanish precedent

Van der Linden cites several similar studies carried out in Spain as precedent, which he dismisses as “inconclusive”. One of them was carried out by Robert Colom, Professor of the Autonomous University of Madrid and published in the year 2000. It was carried out on nearly 7,000 applicants to enter a “private university in Madrid” between 1989 and 1995. Starting from the hypothesis that men should demonstrate an intelligence quotient due to their greater brain volume, it was subjected the subjects to the batch of tests of different cognitive abilities.

The conclusions of the study were that the difference between the sexes was “negligible” (“negligible”) on general intelligence (g). Although the four-point superiority of men over women was manifested, they attributed it to specificities in the tests that privilege masculine faculties of mathematical reasoning and spatial perception. The differences by sex would be manifested “in the modular levels of the brain”, the study concluded, and not in the set of positive correlations between such functions that give rise to our intelligence.
