Are we talking classic conservative versus classic liberal. Your study doesn't say. One hallmark of the modern conservative is to understand the world as it is rather the way the liberal would like it to be. Which sounds more intelligent? Knowing the world or convincing oneself that things are not what they appear.

Here is the genesis of your research and it doesn't look good for Stanza. It seems that Kanazawa uses the argument that people are are more likely to accept new arguments must be more intelligent (remember what I said about trying to imagine the world different from what it is?). He has no proof that this is true. This is just his opinion. It is also pointed out that he uses the idea of people calling themselves liberal is a way of showing their higher intellect but he never proves that they understand what a liberal is. Remember the difference between a classic liberal and a modern liberal? If you don't then you are in the same boat as Kanasawa.
I would say that your intial posting is pretty discredited but you'll never accept that. You see, your just not that intelligent I guess.

Here is another rebuttal and your chart explained.
By the way, my IQ is above 140. Yes, you won't believe it (and neither will the rest of the idiots) but since I know it is true and you can't accept it, I can be pretty smug about how dumb you really are.
While I think about it, does this guys research explain why people get more conservative the older they get? I didn't think so.
