  Symmetry is a fundamental concept in modern physics and other related
sciences. Being such a powerful tool, almost all physical theories can be
derived from symmetry, and the effectiveness of such an approach is
astonishing. Since many physicists do not actually believe that symmetry is a
fundamental feature of nature, it seems more likely it is a fundamental feature
of human cognition. According to evolutionary psychologists, humans have a
sensory bias for symmetry. The unconscious quest for symmetrical patterns has
developed as a solution to specific adaptive problems related to survival and
reproduction. Therefore, it comes as no surprise that some fundamental concepts
in psychology and behavioral economics necessarily involve symmetry. The
purpose of this paper is to draw attention to the role of symmetry in
decision-making and to illustrate how it can be algebraically operationalized
through the use of mathematical group theory.
