Getting people to act more ethically
We have a tendency to watch how we behave when there are others who can testify. Witnesses can help prevent crimes simply by being present before a crime takes place. Do you know shoplifters will keep an eye out for other people but care less about CCTV? It’s all in the eyes.
Something you can do to trick people into behaving is by putting up posters of people staring at you. Even though there aren’t any witnesses, the fact that there’s a pair of eyes staring at us can dissuade us from doing something we shouldn’t be doing. It’s not 100% foolproof, but it works on certain people.
