How genetic variation gives rise to differences in mathematical ability

Summary: gene sequence ROBO1 is found to be associated with the development of gray matter in the right parietal cortex, which is associated with mathematical performance.

Suggested hypothesis: people who argue that 2+2 does not necessarily equal 4, or that “2+2=4 is an expression of white supremacy or the patriarchy or western imperialism or INSERT DUMBASS IDEOLOGICAL NONSENSE HERE” have ROBO1 gene sequence variabilities that lead to *reduced* formation of that right parietal cortex gray matter. Suggested experiment: do some genetic testing and see.

The question would then  become what to do about it. If it turns out that genetics leads to a difference in mathematical ability *and* differences in political ideologies, will that mean that people will start voting for candidates based on their genetic testing results? Will that mean that science and engineering firms will not be allowed to “discriminate” by not hiring candidates who fail math tests if they have the gene sequence for bad math abilities? Will it mean that math test results will be driven in part based on your genes… this person has to give mathematically correct answers, that one doesn’t, in order to achieve the same grade?
