Say it with me:
"IQ IS JUNK SCIENCE INVENTED BY WHITE SUPREMACIST EUGENICISTS TO JUSTIFY THEIR IDEOLOGY"
It is not an "inconvenient truth". It is not an otherwise robust instrument that is misused by some people with an agenda. It is not something that's pretty accurate but that is complicated by societal factors.
It's bullshit. Bupkis. Bunk.
As Johnathan Frakes says in that one show, "We made this one up. It's a total fabrication. It's pure fiction. It's a made up tale. This one was invented by a writer. It's an urban legend... that never happened."
Don't forget. Remind yourself if you have to.
