If intelligence and success are truly largely determined by genetics:<p>- How will our culture ever allow us to even admit the possibility?<p>- If it&#x27;s true and the truth becomes widely accepted, how do we prevent problems ranging from basic discrimination, to a push for eugenics policies, to full-on Nazi &quot;kill all the inferior races in our glorious society&quot;?<p>The answer since WW2 has been basically &quot;that&#x27;s not the way it works&quot; -- but then that means we suppress evidence that points in that direction, and so blind ourselves to the possibility that it is actually the way it works.<p>If what the author&#x27;s saying is the truth, are we better off being willfully blind to it, and avoiding the grave social problems such a truth could potentially cause if widely accepted?  Or should we pursue the evidence wherever it leads?<p>We like to think that our modern scientific society is far more ethically advanced than the primitive, superstitious idiots who put Galileo on trial -- but it seems like this issue may be an example of the same forces at work, and it seems like a lot of the people might come down on the side of suppressing unfavorable evidence.<p>For the record, I don&#x27;t really support the author&#x27;s point of view.  I&#x27;m just playing devil&#x27;s advocate by asking yourself:  If the author&#x27;s right, what evidence would he need to present in order to convince you?
