Studies have suggested that the reason we don't like cheating and rule-breaking is because fairness is programmed into our brains. Tricomi (2010) have found that the brain reacts in a particular way when we feel we are being treated unfairly. The study identified a reaction in a specific part of the brain when test subjects were given less money than others. A fair situation makes our brains respond in ways that lead to feelings of comfort and even happiness, but unfairness causes our brains to respond with negative feeling such as anger and pain. The study found what this also happened when subjects saw other people being treated unfairly. They concluded that fairness is a basic human need along with food and social contact.
