The researcher starts out by admitting that IQ is correlated to income and wealth[1], then keeps adding factors to the model until the IQ factor is statistically redundant. If you think this method is sufficient to say two variables are not correlated, then nothing is correlated. Excluding wealth, none of the variables listed were more strongly correlated with income than IQ.

And thus you’ve discovered why social “science” is not science at all. IQ is a nebulous concept anyway. Yes, if you’re cognitively impaired, there are lots of things you can’t do and that will impact your pay but higher income is related to who you know, not what you do.
