" On average, each judge approved parole for only about one of every three prisoners, but there was a striking pattern to the decisions of all the judges, as the researchers found. The prisoners who appeared early in the morning received parole about 65 percent of the time. Those who appeared late in the day won parole less than 10 percent of the time. Thus, the odds favored the prisoner in our Case 1, who appeared at 8:50 A.M., the second case of the day—and he did in fact receive parole. But even though the prisoner in Case 4 was serving the same sentence for the same crime—fraud—the odds were against him when he appeared (on a different day) at 4:25 P.M. Like most of the other prisoners who appeared late in the afternoon, he was denied parole. "
