&gt; <i>No, it&#x27;s that they have other things they are interested in. Rather than spending 50% of their time on sports, they might spend 10% of their time on sports and 40% on something else. That&#x27;s not a negative thing: it&#x27;s just indicative of the fact that the brighter one is the broader one&#x27;s horizons.</i><p>Has it occurred to you yet that your beliefs here might just be incorrect?  You&#x27;re clearly biased against sports and sports fans, and you&#x27;re letting that affect your critical thinking.<p>Less intelligent people might spend 50% of their time on sports.  They might also spend 0% of their time on sports.  There are a million hobbies that people can have and relatively few of them have anything to do with intelligence.  Smart people can (and do) watch sports, just as dumb people can (and do) hike, bike, fish, paint, cook, homebrew, and play D&amp;D.<p>&gt; <i>it&#x27;s just that physical and intellectual ability don&#x27;t seem (to me) to be highly correlated.</i><p>That&#x27;s true.  There seems to be little correlation between the two.  It&#x27;s critical to realize that the two are not negatively correlated either, though.<p>&gt; <i>I was very careful not to say that intelligent people hate sports, because I too know many intelligent people who enjoy them. All I&#x27;m suggesting is that I suspect that as IQ rises people will spend less of their time on sports because they will spend more of their time on other pursuits.</i><p>I&#x27;m doubting that&#x27;s really the case.  Has interest in sports declined since the 1930s?  Because measured IQ has certainly risen.
