What is the curse of knowledge bias?

The error of evaluating a decision based on things you didn’t know before making the decision.
The bias caused by assuming people have the same background knowledge as you, causing you to use terms that are only familiar to someone with your own background.
The bias that occurs when coming to a conclusion based on data. You assume that you probably could have guessed this information all along and you forget the data you used to come to that conclusion.
The bias that results when you are so tied to your own beliefs that your end up blatantly ignoring data and only going with their own beliefs to make a decision.
