True quote from page 320 of Contracts -- "actor" in this case meaning any party in a contract:
"[A]ctors are unrealistically optimistic as a systematic matter. (Lawyers do not realize this, because they are trained to be systematically pessimistic.) ... For example, the subjects correctly estimated that fifty percent of American couples will eventually divorce. In contrast, the subjects estimated that their own chance of divorce was zero."
I don't believe it. About the pessimism I mean. All my law professors are pretty happy people. Just today two of them brought out a couple student volunteers, a trumpet, a bass and a piano. One professor sang some revised lyrics to "Don't Get Around Much Anymore" based on the Papachristou v. Jacksonville case while the other one? Yup. He juggled.
