Trivia / Spock Must Die!

• Science Marches On: Blish has McCoy state that handedness-retraining is the one and only cause of habitual stammering. There is some statistical evidence of a link, and the popularity of the theory of a connection waxes and wains, but Blish's assertion comes across as hyperbole at best. The idea that handedness-retraining is still an issue in McCoy's time also seems bizarre. By the time the book was published, that had been on the wane or abolished as well.
