though i loven curly fries -- youveryone in this room, know, it is nonsensical that that could have anything to do except by some baroque argument that there is some cultural signal in liking curly fries. i do not see it. does that for just it is not a particular data point, but it is patterns? michal: the power is in numbers. the more data you have about someone, the more accurate prediction would be. even when you look at things like signal theory. i didn't want to bring it up, but look at signal theory -- if you have a real signal, but you add a lot of random noise around it, you just need a slightly more of a signal and you are still going to discover what was the truth there. so unfortunately this is a great idea, but it is not going to work.
