Professor Silva believes that student athletes are lazy and academically incompetent. Every time she has an athlete in one of her classes who is a poor student, she takes note of and remembers it. Every time she has an athlete in her class who is an excellent student, she ignores it. Through this mechanism, Professor Silva ________ her stereotype of student athletes.
Professor Silva is reinforcing her stereotype of student athletes by using a confirmation bias wherein poorly acting student athletes confirm her expectation and excellent student athletes are largely ignored for the purpose of data.
