“to have emotional responses to divergence of IQ.”
Whether you ‘hate’ a dummy or not changes nothing about the dummy’s defensive nature regarding this matter. Knowing one’s intellectual incapacity is an experience and admission of lacking power… and that direct experience of impotence necessarily causes the dummy to be offended by and on guard against smarter people. And all this is perfectly natural.
You can pet a dummy on the head all you want and show not the slightest bit of contempt for him… but if he knows he’s not that bright, he’s going to be bitter about that fact and suspect that someone is gonna cheat him or take advantage of him somehow. Why. Because that’s how it is and has been for eighty thousand years. That dummy’s intuition is a survival mechanism; a dummy stays alive by raising a fuss about all the possible ways he’s being fucked so that he solicits the sympathy of a group majority that can provide for him (because of his relative unproductivity). Prior to this group arrangement, the dummy was either tossed or enslaved.
In any case, admitting an IQ difference between an animal and a human isn’t a problem for either party. But between people, big problem. Why. Because the social contract rests on a few fundamental errors… one of which is that people are equal before some third party (a god, a state, a constitution) and that, therefore, no capacity of one person should give them an advantage over another person. You can be smarter than me but not better, not deserving of more opportunity, not appreciated more, not privileged more, etc. These are the resulting errors of reasoning that cause the rancor and envy of the inferior type.
On the other hand, if a dummy were intelligent enough to rid himself of these notions, he’d not feel any shame in a revolt against his betters. That third-party god he imagines that likes him as much as all the einsteins also acts as a prohibition against the dummy’s natural drive to weaponize himself against his superiors. He behaves himself instead, so his envy gets pushed down and ferments in his primitive soul.
“Thus, Americans are trained, from youth, to hate “high-IQ” and perceive it as a threat.”
In fact, intelligence is a great virtue and still considered so… but the promotion of intelligence and education in a capitalistic society will be in a commodified form to accommodate the demands made by the market. One gets schooled, taught, to prepare for a job… not to become intelligent (enough to call out bullshit). ‘Classical’ intelligence is history, and philosophy courses are taken for fun.
In fact, you yourself are such a student of commodified education and indoctrination. Your understanding and perception of Marxism, for instance, is surgically confused and made that way on purpose by bourgeois western institutions. The irony here is that while you are dumb, what you believe is called ‘intelligent stuff’ by the institutions that raised and educated you. So it’s kind of a paradox. You are pretty fuckin smaht at being pretty fuckin dumb.
