Julia Galef appeared in Episode 462 of Wired’s Geek’s Guide to the Galaxy podcast to call out Spock’s flawed logic.
[…] Not only does Spock have a terrible track record—events he describes as “impossible” happen 83 percent of the time—but his confidence level is actually anti-correlated with reality. “The more confident he says he is that something will happen—that the ship will crash, or that they will find survivors—the less likely it is to happen, and the less confident he is in something, the more likely it is to happen,” Galef says.
Still better than Nostradamus, probably.
