Naturally Spock was always wrong, but nobody ever complained or sent him back to remedial statistics. I'm sure he must have somehow become confused about Bayesian inference. Using Bayes theorem to compute probabilities is of course perfectly legitemate and absolutely necessary for most statistical reasoning, but the Bayesian...
