The IQ test is a test of rational thinking ability. That’s deductive reasoning. Deductive reasoning is what you use to conclude that phony data is not proof of any scientific theory.
“Deductive reasoning (which is what you use to conclude that phony data is not proof of any scientific theory)” will ONLY allow one to make that conclusion if the high than IQ is balanced with/offset by an appropriate level of common sense and/or “unemotionalness”, which by my admittedly anecdotal experiences is NOT guaranteed.
To be specific, high IQ acquaintances of mine subscribe to such drivel as global warming; giving some people other people's money; political correctness; amnesty for illegals; conservatives are all evil, cold hearted villains and the US should ask other nations why they are mad at us and change our behavior to accommodate them.
