Abstract

The relatively young discipline of neuroeconomics has taken an interest in forms of interpersonal trust from its very inception in an attempt to correct one-dimensional overrationalistic pictures of homo economicus. This article analyzes the notion of trust as present in these studies, but also takes a look at typical philosophical ways of criticizing neuroscientific uses of everyday concepts such as trust that insist on their irreducible semantic complexity. It is suggested that these critical approaches are justified, but often underrate the extent to which everyday concepts change or modify their meaning under various social, economic and political pressures. If this is granted, it becomes possible to take a deepened look at the neuroeconomic concept of trust. While it is true that this concept is under the influence of an every_day concept of trust it can be shown that this everyday concept of trust gradually takes on a reduced economic twist. If this fact remains unrecognized neuroeconomics in particular and neuroscience in general can take on ideological functions in reflecting back to society a seemingly natural understanding of trust that is, in truth, highly shaped by economic forces
