How does an article like this get published without summarizing the specific results or quantifying the drop?

Seriously though, they observed a reverse Flynn effect by taking a thin slice of negative test results from a test that doesn’t even measure IQ and finding it statistically significant. This kind of reminds of when climate deniers take a tiny slice of climate records and claim the earth is actually getting cooler.

Unsurprisingly you’ll actually find many IQ researchers in institutions which are still trying to deny climate change. E.g. Charles Murray is now working for the American Enterprise Institute.
