Confirmation bias is important to understand because it will give you insight into yourself, how you and how others process information. We are constantly scanning the world for information that bolsters what we already think is true. Conversely we constantly downplay and ignore information contrary to our beliefs. “Confirmation biases contribute to overconfidence in personal beliefs and can maintain or strengthen beliefs in the face of contrary evidence. Poor decisions due to these biases have been found in political and organizational contexts.”
