Eh, maybe he's just a bad writer but that just seems like its in there as a save-fall. He seems to spend the rest the document arguing against that paragraph.
He also brings up how his reasons are based on biology which he doesn't cite and none of the Big Five tests he seems to get all his talking points ever attribute to biology. They always hypothesize its social development that brings these gendered differences about. Because unless the people being tested then had their brains dissected that's a big leap in logic. Now people do still believe men and women have different brains.
No malice the following quote, friend
However,
The genders physiology is like that of their emotional responses; on a spectrum. Basing policy on gendered biases is misguided at best when is impossible to predict how an individual will react to or handle any situation.
Google Guy also throws in that the gender biases are which like his biotruthbombs is uncited. Its also very not true. The majority of Big Five testing has been done in urban, developed, very literate, westernized cultures. When someone found a culture to test the hypothesis on unlike that:
Google Guy also says his points are Which, boy, kinda screams confirmation bias and is also uncited because his other citations simply speculate to this and most other gender studies don't include at all.
On conditioning, until about 8th grade boys and girls are near as makes no difference in school performance. After that, a gap begins with girls pulling ahead and never looking back. Girls get better grades, are more likely to enroll in math and science classes (including AP courses), and more likely to finish in the top 10% of their class after being more likely to take math and science courses all four years. 70% of valedictorians are girls. If colleges accepted applicants based solely on grades, every male race besides Asian would be nearly nonexistent. Women at a base level are much more likely than boys to attend and graduate from college and go on to graduate schools. And yet for some reason these super-qualified, highly math and science educated women often choose to not enter STEM fields and those that do are greeted by Google Guy and all the people who agree with him.
Citation 11 is... a little much.
