ABSTRACT
Previous work by the authors used an expertise index based on participants’ consistency and discrimination when making judgements about workplace scenarios dealing with Upper Limb Disorders (Williams, Haslam & Weiss, 2008). Consistency and discrimination are two important attributes of expert judgements, but they are not sufficient terms alone to describe it. It is an acknowledged limitation of the expertise index used in the previous work that judges deemed ‘expert’ due to their consistency and discrimination, could nonetheless be wrong, and therefore not be experts at all (Weiss & Shanteau, 2003).
