<p>I hate to go on this rather silly tangent, but...</p>
<p>It's disingenuous to argue that either conservatives or liberals have a higher IQ without any sort of data.</p>
<p>In fact, the "common sense" theory would state that since higher levels of education tend to correlate strongly with liberal opinions, liberals have a higher mean IQ.</p>
<p>But that, in itself, is an argument littered with endogenaity.</p>
<p>Either way, until a good study is done on the subject (or produced here), you're both barking up an invisible tree. And watching a dog bark up a tree that isn't there is really just sad...</p>
