Two hunches: 1) Expertise may cause certain types of bias. Recent studies have examined this idea of "earned dogmatism": the idea that once you gain expertise in something, your ego builds, and that actually makes you less open minded and less able to revise or challenge your existing beliefs.[0] 2) Overcoming bias is different than overcoming ignorance. Categorically different, and perhaps massively harder. A different study found expert philosophers exhibiting cognitive biases at the same rate as nonprofessionals, even when dealing with undergraduate-level philosophy problems.[1] [0] http://www.sciencedirect.com/science/article/pii/S0022103115001006 http://www.sciencedirect.com/science/article/pii/S0022103115...
