In the context of some belief systems, frugality is a philosophy in which one does not trust (or is deeply wary of) "expert" knowledge, often from commercial markets or corporate cultures, claiming to know what is in the best economic, material, or spiritual interests of the individual. Frugality has been adopted as a strategic imperative by large enterprises as a means of cost reduction through engenderment of a philosophy of careful spending amongst the workforce. The term behavioural sciences is often confused with the term social sciences. Though these two broad areas are interrelated and study systematic processes of behaviour, they differ on their level of scientific analysis of various dimensions of behaviour. Information processing sciences deals with information processing of stimuli from the social environment by cognitive entities in order to engage in decision making, social judgment and social perception for individual functioning and survival of organism in a social environment.
