How does expertise apply to the real world?

Expertise is conceptually difficult to pin down, especially because it is applied differently across various domains. Once you have potential theories of the mechanisms of expertise, the next step is to see just how those theories play out in real world situations. How expertise manifests in chess literature, for example, might not be transferable to video gamers and their seemingly enhanced ability to shift focus and scan a region with greater ease than a novice (Castel et. al, 2005). Below are some examples of how expertise has been looked at in different domains. Remember that the efficacy of any good theory is the extent to which it can explain how expertise works in any or all domains.
