IQ is largely a pseudoscientific swindle

Molyneux is a bitch, he gets by cribbing the work of others including those of use here. However as somebody with a PhD in Geology I will say that credentialism is bullshit pushed by the incompetent to protect their job security and social status. All that matters is making predictive models which are reflective of the real phenomenon being observed as much as is possible. IQ is predictive, it is the single biggest factor that predicts what you maximum intellectual capabilities might be within a field you display a talent for. It is not the only factor but it is the one which correlates best with capacity for pattern matching which is key in both constructing new patterns(art) or examining existing patterns(science).

Can you please provide an argument?

So a wife beating sandniggers?

HAHA…hee, no wonder he appeals to people with rocks in their heads

You are a woman, or a VERY feminine "man".

Yup, it's a leftynigger.

Whomever produces a predictive model. Also Molybux doesn't make models he just parrots the data of others and e-begs. You are attacking a strawman. How about the authors of the Bell Curve whose models remain predictive despite 30 years of concerted attempts to debunk them.

To appeal to absurdity is to cede the argument.
