I don’t know the motivations or any biases in that “study”; a study can be used to say anything.
I’m not discounting it, just saying it’s no match for what I have seen in stem education for the last fifty years.
We’ve still got the best no doubt. But we also have fewer every year.
On nationwide issues, nationwide data is more than a match for what any one person has seen.
Weve still got the best no doubt.
Which is what the study says.
