For decades, anti-corruption strategies have been based on an understanding that corrupt people were rational beings, making rational decisions when they decide to engage in corruption. As a result, the rationale was to make corruption as inconvenient as possible. However, contrary to this assumption, social psychology and behavioural economics demonstrate that human decision-making is not always rational. Mental shortcuts and intuition play an important role in shaping behaviour surrounding corruption. This realisation has opened up a new terrain to think of anti-corruption based on how people act towards and engage in corruption. That requires first an understanding of the psychology of corruption and, second, a holistic approach to influence both the mind and the environment in which the individual makes decisions. Awards, as a form of incentive, are among some of the tools that can be considered when designing strategies meant to help curb corruption through behavioural changes.
