The concept of adaptive decision-making is best understood as the mental process of effectively reacting to a change in a situation. In the simplest terms, it refers to problem-solving. There are three major factors involved. First, the essence of the concept is a behavior change. Obstinately continuing a course of action despite significant changes in the circumstances is not adaptive even if it is effective. Second, whatever responses are employed must be effective. It makes no sense if they make things more difficult. Lastly, any response must be in reaction to a change of circumstances. Change for its own sake is not adaptive.
