S/P/83. What is the role of rationality in the explanation of action?

This essay analyses and evaluates the extent to which rational choice theory can explain human behaviour. The literature generally agrees on the point that rationality must at least have some role to play in determining explanations for our actions. The debate arises over the nature and scope of this role. Can actions be explained by rationality alone? This essay argues that to espouse such a position would be questionable and almost certainly wrong, whilst hopefully maintaining the reasoning for why rational choice must still be considered in analysing our actions. As such, the key drawbacks of rational choice theory are discussed, along with attempts by some to adopt holistic rational choice approaches.
