The purpose of this paper is to illustrate the political nature of laborato
ry experiments. Such experiments can be construed as paradigms of power, op
en to construction and debate, where different agents and interests are inv
olved in a process of struggle over both (re)presentation and substance. Ex
perimenters should take a reflexive perspective on their own role and power
in producing results, and they should recognize that participants in exper
iments take into account port er relations and accordingly modify behavior
that is visible or accountable to powerful others (the "panopticon "). This
argument is illustrated by recent research on intergroup behavior, which s
uggests that biases often taken at face value reflect strategic responses t
o the situation that balance social reality with social resistance.
