The behavioral and social sciences.

In the social sciences, as in other sciences, progress is often placed by advances in observational techniques and instruments. This article reviews some of the recent technical progress in the social sciences ans then discusses three substantive frontier areas that are particularly exciting at present: evolutionary theory, especially in relation to sociobiology, the theory of human rational choice, and the newly christened discipline of cognitive science. All three claim to provide explanations for broad areas of human behavior.
