See how in your own link one of the authors says indeed how the decline in results is because we have gone too woke:

  Dworak, a research assistant professor at Northwestern University and one of the authors on the study, is very clear that these results don’t necessarily mean Americans are getting less intelligent. “It doesn’t mean their mental ability is lower or higher; it’s just a difference in scores that are favoring older or newer samples,” she said in a press release. “It could just be that they’re getting worse at taking tests or specifically worse at taking these kinds of tests.”

No wait, they say nothing of the kind. And it seems people are getting better at 3D-thinking and decline is not the same in every topic measured so…

Man, your referencecreally does not support the narrative to which you are trying to bend the reality.

You're reading into things as you want to read into them. I am saying that the rejection of reality, which includes but is certainly not limited to 'woke', is the problem. IQ is full of examples in this domain because it tends to provide measurable data that regularly contradicts ideological views. I think the author's own response is a perfect example.

She finds that people are scoring significantly worse on most measurable aspects of IQ and so she concludes that they may simply be getting worse at taking tests? Let's imagine in a parallel world (or China...) she did the same study and found that scores were increasing. Would she have suggested it may simply be because people are getting better at taking tests? Almost certainly not, because it's a highly improbable explanation with no foundational basis whatsoever. If you don't think the tests you're using to evaluate something are evaluating that thing, then why would you use those tests?

So why would she make the claim in one scenario, but not the other? Because of ideology. We obviously want IQs to be going up, and so the ideological value is given at least equal weighting, if not more, against the significantly more probable 'natural' explanation when the 'natural' explanation goes against ideological desires.
