Didn\'t they sometimes have problems with people buzzing in too soon, or two podia lighting up at the same time?
Not the latter, there was never a problem with the lockout system (at least nothing that ever aired).
According to a book by one of the show\'s clue writers, smart players would assume (reasonably, in most cases) that they\'d know the first few clues in any given category, so those players would ring in as soon as they were able to do so, usually before Alex had even begun reading a clue. This presented two big problems for the show. inevitably, there would be clues that the player didn\'t know after all, but the show still had to tick away those precious seconds while he stands there blankly. Secondly, some players weren\'t nearly as smart as they thought they were, and the result would be large negative scores. This would be a particular problem late in the game when someone tried desperately to catch up.
Forcing the players to wait took care of those problems, but created a game which, especially in the early round, became less about knowledge and more about eye-hand coordination.
