We've examined the topics of IQ (theoretical and applied), education and ability on several occasions in these pages. If you'd like to read the earlier articles:
IQ, countries, and coping skills
IQ and potential, both individual and national
Karl Denninger warns that the flood of lower-IQ migrants across our borders threatens to lower our national competence to cope with issues and problems. (WARNING: He uses more profanity than usual in his article.) Here are some excerpts. Emphasis in original.
You won't like this and I don't care.
You're going to die if you don't take this to heart, or even worse your kids will die.
What am I talking about?
Quite simply its this: You need about a 115 IQ to build and maintain modern civilization.
Examples? Too many to count. How about Flint's water system? It poisoned a bunch of kids, remember?
Why didn't it poison kids for the previous 80 years? It had been there that long, with the same lead service lines, but didn't poison anyone ... The 115+ IQ people who built and ran the water plant at Flint all those years knew this, and knew how to keep it safe. They drank out of the same lines and so not only did they know how they had plenty of incentive to not screw up -- and as professionals who were smart, they didn't screw up.
Then Shaqueena, or her analog with a <115 IQ took over. And changed the water source. And, at the same time, didn't check and make sure the chemical and pH balance remained correct because the intellectual firepower to do so was simply no longer there. The result was a bunch of poisoned kids.
. . .
Why do I bring all this up?
Because if we do not stop destroying the incentives for those on the right end of the IQ bell curve to have kids it will not be all that long before you go to flush the toilet and it won't, your stove, heat and A/C won't work either because there's no power or gas and virtually everything we rely on in the modern world will either kill you or simply not function at all.
Its much worse when people who simply don't have the intellectual chops for a given task are passed in school and given credentials they didn't earn.
. . .
Those who built all these things we enjoy today and in fact are the reason we can have several billion people on this planet -- most of them created by white men, and all of them by persons of >115 IQ -- are going to die. We all die; it is inevitable. If we do not stop demonstrating to those who are of higher intelligence that the only reason to have kids is their own hedonism, and by doing so for hedonistic purpose they will screw their offspring as those kids will have a s***ty future said people will choose not to breed as they are choosing right now. The data is clear in this regard -- those who are of higher intelligence are choosing not to have kids and since they are of higher intelligence it is obvious that they are capable of reasoning out the incentives and disincentives, weighing both for themselves and what they perceive as the future for any children they might choose to produce -- and that analysis, once complete, is unfavorable as they see it.
People often claim that as societies advance the people tend to have fewer children. That's a true statement but did you notice that the "why" is never discussed? As societies advance inevitably people are led to believe, often by active fraud peddlers, that you can have something for nothing and the more-intelligent discern that it is likely their children will get ****ed by this pattern. Said persons have no means to stop it peacefully as they're out-represented (by definition > 115 IQ is at least one standard deviation out on the right side and thus they're out-voted roughly 6:1) so they simply choose not to have children at all. This inevitably results in the average of the curve shifting leftward unless it it is stomped on hard.

Like Mr. Denninger, I and many others have warned that "If you import the Third World, you become the Third World". We're seeing that in action right now. Despite the progressive left's demonization of IQ as a First World approach that automatically reduces equality and diversity in our workforce, IQ remains the single best indicator of whether or not a nation, or a city, or an organization, can and will prosper. Higher IQ = better chances of that happening. Lower IQ = lower chances of that happening. It's as simple as that.
