Jerk-o-meter

So apparently there is this neat little device which can help people find out when they sound like a jerk on the phone. Of course, the device can also tell you when the other person sounds like a jerk.

This is just what we need, a new technology to tell people what their emotional state should be. Thanks science! Why don't the annals of academia dream up a machine to tell us when we're sounding loving, happy or drunk?

Boycott, please. If this machine becomes popular then becoming an oil worker will sound pretty appealing.
