To motivate people to engage in positive behavior, it is crucial to recognize and reward their actions publicly. For instance, a small acknowledgment like a smiley face on a bill can significantly encourage individuals to maintain good behavior. This approach of providing positive reinforcement is shown through research to be more effective than merely criticizing negative actions.

By shifting attention to commendable behavior and reinforcing it, you create an environment where individuals are more likely to continue doing the right thing. It's about building on the positive rather than focusing solely on the negative.
