Behavioural decision science applies psychological insights into human behaviour to explain how, when and why people make decisions. The course is based in Kingston University’s Psychology Department. The course examines the application of psychology, behavioural science, and behavioural economics to policy, intervention, and behaviour change in areas such as health, finance, sustainability, and consumer behaviour. Behavioural decision science can be used to study people who are not willing to change their behaviours. Instead, through the use of nudges (subliminal changes in the environment), theory in this field can be used to influence people’s choices. I believe that it would be really interesting to try to implement these theories in Lebanon, which I aim to do once I graduate.
