With Watson getting all three Daily Doubles so easily, I think that it's "interfacing" with the computer controlling the big board to get the secrets (or else it has 25 years of Jeopardy games memorized and knows the statistical distribution of DD locations).
I’ve been working with computers since 1955.
Turned Jeopardy off in the middle of Watson’s show.
Good old IBM. An informercial at best.
The players, and for that matter Alex, see the question pop up on a screen at the same time as the studio and home audience. Neither Alex nor any of the staff know what it will be before this point.
I very much doubt there’s any funny stuff going on at the computer level. The studio has an entirely separate division that is super-paranoid about security and accusations of collusion.
It is entirely possible Watson or some human competitors get some up-front clues, but I sure didn’t!
