What do you think that picture is meant to say? To me, it is meant to convey that regardless of political affiliation, more "intelligence" makes you believe in your convictions more strongly, whereas - regardless of political affiliation - being more curious barely affects your beliefs, except to make you less skeptical of global warming.

So I didn't see that image as bigoted.

You apparently found it interesting enough to get to that picture, which is pretty far down in a fairly long article. That would indicate that it has some worth.

It isn't claiming that one side is more intelligent than the other. It's talking about curiosity vs. intelligence and how that affects how people of different belief-sets agree or disagree with a given statement.

You're really inferring a lot from this image that isn't there. It is clear there isn't an intent for this image to be "Dems are smarter than Repubs", but it's very telling that that is all you get from it.
