On Changing Behaviour in Fixed Psychologies: An Integrated, Holistic, Systematic Approach

We develop an integrated, holistic and systematic model of behavioural change in fixed psychologies by making use of a model of the psychology of behaviour. We identify and explain three simple and comprehensive means by which behavioural change is affected by the interaction of the individual's psychology with their environment. This has value for the pure theory of human behaviour, for applied theory (making hypotheses to appraise and to be tested by datasets), and for the practice of policy by demonstrating a fairly simple causal structure underlying the seemingly highly individuated and complex psychological processes which support behavioural change.
