The belief–desire–intention (BDI) model of human practical reasoning was developed by Michael Bratman as a way of explaining future-directed intention.
BDI is fundamentally reliant on folk psychology (the 'theory theory'), which is the notion that our mental models of the world are theories.
BDI was part of the inspiration behind the BDI software architecture, which Bratman was also involved in developing. Here, the notion of intention was seen as a way of limiting time spent on deliberating about what to do, by eliminating choices inconsistent with current intentions.
BDI has also aroused some interest in psychology. BDI formed the basis for a computational model of childlike reasoning CRIBB. It has been proposed that autistic children do not recognise other people as folk-psychological agents (i.e., agents with their own beliefs, etc.). BDI has been used to develop a rehabilitation strategy to teach autistic children to reason about other people.
It could be argued that the BDI model is now becoming somewhat dated: the principles of the architecture were established in the mid-1980s, and have remained essentially unchanged since then. With the explosion of interest in intelligent agents and multi-agent systems that has occurred since then, a great many other architectures have been developed, which, it could be argued, address some issues that the BDI model fundamentally fails to. Furthermore, the focus of agent research (and AI in general) has shifted significantly since the BDI model was originally developed. New advances in understanding (such as Russell and Subramanian’s model of “bounded- optimal agents”) have led to radical changes in how the agents community (and more generally, the artificial intelligence community) views its enterprise.
