A related effect that I've wondered about is: perhaps lower-skilled people compare themselves to the general public, while perhaps skilled people compare themselves to a smaller group of skilled peers. In other words, if you asked me if I'm good at riding a bicycle, I'd compare myself to others in the general population and say "yes". But if you ask a weekend bicyclist, they'd be better than me but perhaps compare themselves to weekend bicyclists, and rate themselves lower. And the effect might repeat for competitive bicyclists. If true, this could explain why we intuitively believe the DK effect.
