How can hospitals make sure people wash their hands to prevent the spread of infections?
Place a picture of a set of eyes near sinks. According to a study of people entering an intensive care unit, when there was a picture of eyes posted near the sink, people were twice as likely to wash their hands on the way in. That’s because the feeling of being watched makes people behave better and act more honestly. Researchers from Newcastle University in the U.K. say our brains are wired to lock in on faces and facial features. And we’re quick to tune into the feeling of someone watching us – and when they are, we automatically adjust our behavior.
