"Conservatives performed objectively less well than liberals at this particular task. Full stop."
Pure rubbish.
The methodology of this study is basically that of a video game. For starters, I'd like to know how good the study's self-identified "conservatives" and "liberals" are at video games, respectively.
Second, I'd like to know what you (and the framers of the test) mean by "conservative" and "liberal". The problem with self-identification is that Participant A and Participant B may both call themselves "liberal" but mean quite different things by this word. Subjective self-identification thus fails to provide adequate grounds for objective comparison. It is quite a leap from "self-identified 'conservatives' scored x" to your "conservatives performed objectively less well". "Conservative" and "liberal" fail to carry much meaning unless they tell us "conservative with regard to what?" or "liberal with regard to what?".
Are we really supposed to believe that a politically and economically conservative investment banker will be less inclined to adapt to sudden market changes than a culturally/politically/economically liberal English teacher? Please.
This study seems to demonstrate that the people who are lacking in the analysis-of-complexity/ambiguity department are precisely the ones who framed the test.
