What is the connection between cognitive dissonance and confirmation bias? Intuitively, I'd think that cognitive dissonance (CD) is one explanation of confirmation bias (CB), since if it's the case that most people believe "I am right about most things", then admitting one is wrong about something is dissonant with that. Searching "cognitive dissonance confirmation bias" I found a ton of (almost all non-academic) places asserting something similar, but no concrete evidence linking the two. Moreover, I don't see anything about CD here or in any of the various other places I've read about CB.

Is there any research that identifies a connection between the two and tests it?
