The Nudge: A Nobel Winning Solution to Increasing the Recycling of Mercury Containing Thermostats?

I have a writer friend who loves the word tripwire. He favors it because it implies immediacy, power and effect. We often think of a tripwire as a device that sets off a bomb or booby trap. I prefer the word nudge. While it lacks the firepower (if you’ll forgive the pun) of tripwire, it has a more realistic feel and is easier and safer to understand and implement.
