How does confirmation bias differ from cognitive dissonance?

Confirmation bias is the tendency to seek out and interpret information that aligns with one's existing beliefs, while ignoring contradictory evidence. Cognitive dissonance, on the other hand, is the mental discomfort experienced when holding conflicting beliefs, attitudes, or assumptions, or when new information contradicts existing ones. People resolve this dissonance by rejecting new information, reconciling differences, or finding other ways to maintain mental stability. While confirmation bias is a way to avoid cognitive dissonance by reinforcing existing beliefs, cognitive dissonance is the resulting psychological conflict from incongruent ideas.123
