Interesting that it also seems to handle false positives well:

> Among other things, the new method makes it possible to detect "a false sit" (when a dog sits to signal that it has found something). "In traditional signal behavior, 'a dog's trick' is hard to detect: The dog does not smile, it does not wink," says Zaripov. "In this case, however, an encephalogram shows that the dog has a conscience. Deep down it knows that it has made a mistake. The reaction of its central nervous system is completely different."

I can imagine lie detectors being deployed to test whether I was motivated to order a hamburger because of an advertisement I noticed.
