What logical evidence do Levitt and Dubner present in response to the counterclaim that a 7–7 wrestler might be more motivated to win and therefore perform better? In the next match, 7–7 wrestlers’ results drop below their predicted percentage. The 7–7 wrestlers do well against both 8–6 and 9–5 opponents. Wrestling matches only last a few seconds and are won by a quick exertion of force. Wrestlers from the same stable do not oppose one another.
