Nudges guide a person to do the right thing (i.e., encourage compliance) without a mandate. Here's the latest one, which was featured by NPR yesterday: the sink-urinal. This allows men to pee in the bottom part of the fixture and wash their hands in the top. It provides a constant reminder to wash your hands. It's environmentally friendly as it uses gray water (from the sink) to flush the urinal. Plus, it comes in an assortment of colors; what more could you ask for?
