When I hear the term "being a team player" I cringe. This reminds me of the antagonist in an Any Rand novel. Someone seeking to suppress the importance of individual worth for groupthink.
If you were to grade your own bias how would you rate yourself on your impact professionally and individually? Can you make improvements? Many people probably believe they aren't prejudiced. We trust ourselves to be ethical and impartial, too. Inside the workplace, however, we likely believe we’re true decision makers, able to objectively determine a candidate or employee’s overall performance and accomplishing a rational and honest end.
At the risk of being an outlier I am just going to say it by quoting Dr, Martin Luther King Jr., “There is nothing more dangerous than sincere ignorance and conscientious stupidity.” I am convinced black people misunderstand racism and bias as much as white people.
