I have data of 2764 people who did Raven’s and Mill Hill Vocabulary Test. I am not going to give details about the source, as this is not a scientific journal, and I am just interested in sharing the information. There were slightly more women, therefore I deleted those extra women with lowest results. This should actually favor women, but it did not change the results much.
I have to say that I am only interested in truth. The fact that a certain gender/sex has higher IQ does not effect my intelligence. So I have no interest in proving men are smarter, but I just want to know the reality.
Íntelligence differences between males and females has long been discussed. My observation was that the higher the intelligence, less are women. The history is full of male geniuses, scientists, artists, leaders, etc. However, very few of them are women. Many people argue that it is so because of culture, society, etc… I believe there are some biological reasons, and culture is also one of the results of those biological factors. I also belive that because of male-male competition to have access to women and resource, male intelligence ( IQ) as well as body size, mascularity and other fitness factors are elevated/increased.
In the Raven’s and Mill Hill Vocabulary Test results, one can see the difference of the male performers and female performers. Best male performers are compared to best female performers. And aslo average and worst male performers are compared to average and worst female performers. I summed total scored points, and ordered males from best to worst, and females from best to worst. Then took the difference.
The results clearly show that the higher the intelligence (IQ), the more males there are, or less females. And also at the lower end of scale, the worst performers are also males. Therefore we can conclude that males have higher standard deviation in intelligence (IQ) than females. The charts are below:
As you see, the results are consistent in both tests. And also consistent with my observations.
