I&#x27;m arguing the point, yes. I&#x27;m saying that IQ is an arbitrary measure and who
knows what it&#x27;s measuring. Others have pointed out that race is also an
arbitrary category and that skin colour is not necessarily the same thing as
having the same genetics.<p>So basically we have an arbitrary measure correlated with another arbitrary
measure. We don&#x27;t have much to draw firm conclusions on.<p>And that agrees with the other thing you bring up:<p>&gt;&gt; &quot;Iq .. is a massive predictor for success in life.&quot;<p>That may just as well be an outcome of racial bias against non-whites in the US.
In which case, IQ would be a pretty accurate measure of racial bias, but not of
intelligence.<p>You&#x27;re asking &quot;so why do blacks score lower in IQ tests?&quot;. I&#x27;m answering: who
knows why. The fact that they do means the test is probably broken, not that
they&#x27;re less intelligent for real.<p>Basically, any test result that just so happens to agree with some widely held
societal belief should set the bias alarm off.
