Continuing some thoughts on “The Making of an Expert”, authors Ericsson, Prietula, and Cokely provide a definition of expertise.

Real expertise must pass three tests. First, it must lead to performance that is consistently superior to that of the expert’s peers. Second, real expertise produces concrete results. …Finally, true expertise can be replicated and measured in the lab.
