In decision theory and general systems theory, a mindset is a set of assumptions, methods, or notions held by one or more people or groups of people. A mindset can also be seen as arising out of a person's world view or philosophy of life.A mindset may be so firmly established that it creates a powerful incentive within these people or groups to continue to adopt or accept prior behaviors, choices, or tools. The latter phenomenon is also sometimes described as mental inertia, "groupthink", and it is often difficult to counteract its effects upon analysis and decision making processes.
In cognitive psychology, a mindset represents the cognitive processes activated in response to a given task (French, 2016).
