Actually, this was supposed to be "Target knows that *your daughter*
is pregnant before you do."
That being said, since people's buying habits are deeply tied to
unconscious processes, I wouldn't be surprised if you could conclude
things about people that they themselves don't know (or don't want to
admit to themselves). :-)
I also believe that search-engine reach is more broad than actual
purchase tracking because searches reveal what you want and/or are
curious about, not just what you actually buy and do.
And in a world where law enforcement is (understandably) desperate for
correlation, if it just so happens that all terrorists eat bananas,
you'd better keep your lunch in a Faraday bag. Especially if you're
*not* a terrorist.
