You use technical terms like "sufficient" and "replicated", as though you actually understood how science worked, but then link to a pile of crap scholarship published in third-rate journals by cranks and racists. It's annoying. And dangerous. Worse, you appear to be completely unaware of the distinction between correlation and causation, and what policy implications that has. Kindly get a clue.

Can you look at the data and come to a different conclusion rather than attack the paper ad hominem?

This opinion is heavily biased toward a white-nationalist narrative. For instance, the second linked “study” is actually a propaganda piece published by the New Century Foundation, an organization described by its founder, Jared Taylor, as “white-separatist”.

HN is not the place for this.

Can you find something wrong with the research itself in any of the papers that I linked?

I miss when HN throwaways were used to serve as whistleblowers.

Not for spreading "The Bell Curve" 90s research and unsourced white nationalist propaganda.

Can you share one of those studies?
