Dr. Glurpple is familiar with the relevant empirical research and finds it hard to understand why so many players, coaches, fans, and analysts believe in the power of sports momentum. If only people would think more carefully about the alleged streaks in performance that they take as supportive evidence, he argues, they would know better. Aside from recognizing this as an instance of hindsight bias (the feeling that something seems obvious or inevitable after the results are known), what is Dr. Glurpple overlooking with respect to the ability to think critically about a phenomenon like sports momentum? In other words, is it sufficient to “think more carefully” to arrive at a more accurate conclusion?
