I thought this was an interesting TED talk video about bias (https://www.ted.com/talks/j_marshall_shepherd_3_kinds_bias_that_shape_your_worldview?utm_campaign=tedspread&utm_content=talk_of_the_week_image&utm_medium=referral&utm_source=tedcomshare). Even us geeks/nerds occasionally engage in bias, particularly confirmation bias so it's something to think about. It's about 12 minutes long.
