Not so smart, are you Watson? After pulling ahead early Monday, IBM computer “Watson” slowly lost its lead on Jeopardy! to former champion Brad Rutter. After the first round, Rutter and Watson are tied with $5,000 each. (The third contestant, Ken Jennings, trails with $2,000.) The computer was particularly troubled by a category in which contestants were read several events and asked the decade in which they occurred. Double Jeopardy airs Tuesday night.
