It probably has a genetic component? A moderately intelligent person would read the research on the links between IQ tests and education, physical health, diet/nutrition, reading proficiency and lots of other factors. That never occurred to you.
A moderately intelligent person would want to know the factors that correlate with high or low IQ test scores. That never occurred to you.
You said that different people have different interests. A moderately intelligent person would want to know the correlations between personal characteristics and interests. But that didn’t occur to you. You just assumed that the correlation was race or gender.
And you say other people are anti-science?
Do you think science says that intelligence is race based? Apparently you do, though, as you admit, you don’t care about the actual research.
You assume that because someone told you that some people in Africa (which people, what education level, what nutrition level) have low IQ test scores that African people are genetically dumber?
That’s the opinion of a person with only a high-school education who gets his “science” from white-supremacist comic books.
