Prior to reading that one study, I would be in complete agreement. After, though, I'm not so sure. Really for any job where routine judgements are being made, I would have just naturally assume that habit would take over. That's why the study was jarring for me; it really does seem to demonstrate that at different times, supposedly expert decision makers came to different conclusions based on their physiology. Now, it could be that legal issues are more based on personal opinion and biases, and really don't rely on making decisions based on rational standards. My thinking, though, is that these are two domains (medicine and law) that share the common element of making a decision based on certain pre-established criteria.
