SNE) Pictures-produced show, while opening Wednesday's episode. "Watson is fast, Watson is capable of some weird wages and Toronto is a U.S. city." Trebek was referring to Watson's second-night gaffe of a Final Jeopardy answer, in which Watson answered "Toronto???" for a clue titled "U.S. Cities." Watson had no such trip-ups Wednesday. He opened the round in much the same way that he dominated Tuesday's segment, continually beating Jennings and Rutter to the buzzer, which had reporters wondering if Watson holds some sort of advantage in ringing in. IBM researchers, who hosted a screening of the show for reporters in New York City and San Jose, Calif., Wednesday, say no. Humans, they say, have the advantage of being able to interpret the clue before Trebek finishes speaking -- Watson doesn't. And while humans must wait to see a light that signifies it's OK to buzz in, Watson waits for an "enable signal" that's sent to him via wire. If Watson is highly confident with an answer, he can buzz in as quickly as 10 milliseconds. "When it comes to buzzing in, humans have the advantage -- they just aren't consistent," said David Ferrucci, the project manager for Watson. To explain the times when Rutter or Jennings beat Watson to the button, Ferrucci noted that a look at Watson's answer confidence levels -- which Jeopardy displayed for each question -- showed that he wasn't happy enough with his top-choice answer to ring in. "It wants to get beaten when it doesn't have high confidence -- it doesn't want to look stupid."
