Football scores are an imperfect measure of a team's ability, and consequently exaggerate differences in abilities. Those teams that perform the best and the worst are not really so far from average in their ability; thus their future performances regress to the mean. Betting data indicate that gamblers do not fully account for this regression.

足球博彩中的反应过度。

足球分数不能完美衡量球队的能力，因此会夸大能力差异。那些表现最好和最差的团队实际上并没有达到平均水平。因此，他们的未来表现会下降到中等水平。投注数据表明，赌徒并没有完全考虑这种回归。
