All through last century, the Austrian School of Economics introduced a series of original and interesting ideas into social sciences, which are still fruitful for contemporary research. We are not referring only to the ideas that are particularly relevant in economics, such as marginal utility, competition, market, entrepreneur, time irreversibility, information, risk, uncertainty, economic cycle, money, theory of capital, public choice, to mention only the most relevant ones. What we have in mind is ideas relevant for all social sciences: methodological subjectivism, apriorism, human knowledge, human action, decision making, praxeology, human freedom, evolution, nature and role of institutions. The ideas expressed by the authors belonging to this school are often so heterogeneous, that they are rather a composite collection of ideas than a single consistent corpus. Nevertheless, a few common aspects characterize the school as a whole.

Cognition and psychology have become central issues in economics. While this interest represents a radical change in economic theory, it does have a useful history that we believe is only partially recognized by contemporary economists. Although it is customary to cite Herbert Simon's important work in this regard,¹ we suggest Hayek's earlier work The Sensory Order (1952) should enjoy similar billing.

The cognitive sciences, having emerged in the second half of the twentieth century, are recently experiencing a spectacular renewal, which cannot leave unaffected any discipline that deals with human behavior. The primary motivation for our project has been to weigh up the impact that this ongoing revolution of the sciences of the mind is likely to have on social sciences – in particular, on economics. The idea was to gather together a diverse group of social scientists to think about the following questions. Have the various new approaches to cognition provoked a crisis in economic science?¹ Should we speak of a scientific revolution (in the sense of Kuhn) also in contemporary social sciences, occurring under the growing influence of the cognitive paradigm? Above all, can a more precise knowledge of the complex functioning of the human mind and brain advance in any way the understanding of economic decision-making?
