Here's a cool paper reporting results of study of French judges vs. members of public. Like we did in the study we report in "Ideology" or "Situation Sense"? An Experimental Investigation of Motivated Reasoning and Professional Judgment, Univ. Pa. L. Rev. (in Press), the authors used a theoretical framework that conceptualized their study as testing the resistance of expert judgment to influences known (and shown in the same study) to bias non-experts.
Also very cool is that it used behavioral rather than experimental data. B/c no method of study is perfect, the only "gold standard" for research on human decisionmaking is convergent validity. (This approach assumes, of course, that studies reflecting the diverse methods in question are themselves validly designed, which is a separate matter.)
