Let's pretend for a second, that you just don't know how to write a simple thought in a coherent way, accidentally tried to say "the stereotype blacks are stupid is true", and aren't instead just backpedaling from your original shitty comment after being called out...
You say it's a difference in environment, so why use that difference to defend a statement like "blacks are stupid"?!
Why try to make a try and enforce a racist statement like "blacks are stupid", that's actually _less valid_ and _much more easily disproven_ than the hypothesis you claim you're _actually_ backing, that environmental differences lead to differences in intelligence?
After all, while it's trivial to find studies questioning the reliability and validity (not just statistical validity) of IQ tests... it's _more_ trivial to find studies showing the effect of different cultures on IQ tests ability to even measure intelligence: https://www.semanticscholar.org/paper/Culture-Fair-Cognitive...
_The study you link is making connections to race with specific goals in mind that have nothing to do with trying to defend a stereotype as heinous as "blacks are stupid". In fact their point is literally the opposite, that what appears to be a simple gap in races, is actually a reflection of environmental differences._
It's clear to me that your own underlying bias caused you to try and draw a conclusion that literally does not exist, and you internally try to write off every single attempt to call out your own stupidity as pearl clutching.
It's literally the opposite of defending a statement like "blacks are stupid"
No testing gap being closed is continent on people "not sweeping under the rug the fact that blacks are stupid!"
Now, let me be a little personal here, you are the worst kind of person and part of a growing plague.
This new wave of people overestimating their intelligence and understanding, and undervaluing basic human decency because "it flies in the idea of logic!" and "you're only mad I said something heinous because of <insert overused logical fallacy>!!!!".
There are a lot of truly awful things that you can justify if your only criteria is "I can misconstrue a study to make a shitty defense of it!"
Do your friends at "Lean St" know that you spend your time defending statements like "blacks are stupid"? Maybe you should tell them?
