This is nothing more than propaganda. The undeniable truth is that IQ proved itself a useful tool when it was shown that IQ scores predicted lifetime achievement better than every other metric combined, including wealth. The more you control for other factors the better IQ predicts success. If you select only black kids from the Bronx and test for IQ you can almost perfectly rank them in lifetime earnings from before they ever get thier first job.

For whatever reason (((someone))) has made it thier mission to deny humanity this tool. Maybe they genuinely feel bad that potentially this could lead to the most unfortunate, low IQ people having to deal with even more obstacles as the opportunities are funneled to the competent. Maybe they don't want efficient societies because they benefit from chaos. Maybe they get too much use out of using racial discrepancies caused by IQ differences to push thier racism narrative with which they attack whites.

The WHY is speculative. The fact that IQ measures something real that might as well be called intelligence is undeniable. Don't fall for the Jewish games of symantics where they try to define intelligence as some bullshit that can't be qualified and measured just so they can deny IQ.
