Sure, but that's just giving people compliments or confirming their world view, isn't it? I did understand the comment to mean that we find things obvious after we hear about them presented as the result of a study. I don't believe that at all, but I'm very much with you that it's correct with a modification: we find them obvious after hearing about them if they agree with our world view.
I don't think that "ideology lessens your ability to perceive reality" falls under worldview, though, and I cannot imagine that anybody was surprised by the result itself. That doesn't make the study useless, it's interesting and important to know how strong the effect is, whether it changes over time or can be negated etc. But other than that? Study finds that people shot with guns die more often than control group. I don't think you need to be an anti-gun-activist to say "well, duh".
More importantly: how did independents and apolitical people guess? Were they closer to the "real" numbers?
