What is interesting (if I interpreted the study correctly) is that the study shows that expert poker players are probably losing out on money because of "the false consensus effect." Like the top scorers of the various tests in the study they carry the burden of not knowing how competent they are in relation to other testers/players.

Of course one might argue that being a poker "expert" as opposed to a logic or standard grammar "expert" requires knowledge of your skill in the subject field as compared to other peoples skill levels. Therefore they do not carry the above-mentioned burden. This may make the study, which is a general analysis even more pertinent to a discussion of poker.
