In 1994, Friedmann successfully applied to Mensa, whose members must present an I.Q. score that is at least in the ninety- eighth percentile, and he began publishing letters in that group’s newsletter. Soon he was approaching bigger publications, eager to challenge ignorant portrayals of prisoners in the press. In a letter to the Tennessean, he corrected the syndicated columnist Mike Royko’s reporting about Mumia Abu-Jamal, an activist who had been convicted, perhaps unfairly, of murdering a police officer.

In those letters, he took a progressive tone. But in 1995, when he wrote to Science News to object to an article pondering “why lawbreakers often brandish low I.Q.s,” he sounded conservative. “Criminality is a conscious choice,” he asserted. “If not for the element of conscious choice, how could researchers explain why I—a member of Mensa with an upper-middle-class background—am serving a 20-year sentence for committing an armed robbery?”
