Abstract
The so-called expertise defence against sceptical challenges from experimental philosophy has recently come under attack: there are several studies claiming to have found direct evidence that philosophers’ judgments in thought experiments are susceptible to erroneous effects. In this paper, we distinguish between the customary ‘immune experts’ version of the expertise defence and an ‘informed experts’ version. On the informed expertise defence, we argue, philosophers’ judgments in thought experiments could be preferable to those by the folk even if it were true that philosophers’ judgments are no less immune to confounders than judgments by the folk are. We present results from an experimental study comparing philosophers and non-philosophers (n = 484), which support this version of the expertise defence.
