Describe what is meant by nudging.

A key feature of "nudges" is that they are subtle, low-cost ways to gently nudge people toward making better choices for themselves and others. This subtlety means that nudges can cause large changes in behavior without making people feel bullied or coerced, and also without imposing stringent new rules or having to offer people big monetary incentives or disincentives to get them to do something. Successful nudges can be viewed as a form of manipulation since the changes in behavior generated by successful nudges are most likely unconscious on the part of those being nudged.
