The new ones that are being used now are much more accurate - no cultural bias or language barrier, just shapes and pattern recognition.
so the new version is better than the previous one that failed? It's based on...? On the old one? Okay, I rest my case. But I do like the original concept of IQ test to separate races
So they have improved a test to measure a conceived, hypothetical concept like intelligence which can't be measured. Well, good luck Is the next thing they measure the social contract?
