"Science" sez stupidity, conservative beliefs, and prejudice are linked

I wouldn't consider this "science" as being settled:

Low IQ & Conservative Beliefs Linked to Prejudice

These paragraphs appear to drive the headline:

There's no gentle way to put it: People who give in to racism and prejudice may simply be dumb, according to a new study that is bound to stir public controversy.

.... [snip] .....

Polling data and social and political science research do show that prejudice is more common in those who hold right-wing ideals that those of other political persuasions, Nosek told LiveScience.

.... [snip] .....

As suspected, low intelligence in childhood corresponded with racism in adulthood. But the factor that explained the relationship between these two variables was political: When researchers included social conservatism in the analysis, those ideologies accounted for much of the link between brains and bias.

The lead researcher does note that this is a "study of averages":

Hodson was quick to note that the despite the link found between low intelligence and social conservatism, the researchers aren't implying that all liberals are brilliant and all conservatives stupid. The research is a study of averages over large groups, he said.

"There are multiple examples of very bright conservatives and not-so-bright liberals, and many examples of very principled conservatives and very intolerant liberals," Hodson said.

 How kind of him.  And how .... unbiased .... of the media to use such a thoughtful headline. 

Me, I'm reminded of the old rule of thumb:  "There are three kinds of lies: lies, damned lies and statistics."
