It has been proposed that decision makers often misperceive
the feedback provided by dynamically complex environments,
and some have questioned whether people are capable of
learning effective decision-making in such environments.
Indeed, some (e.g., Sterman,1989) researchers believe that
humans simply do not possess the “cognitive machinery” that
allow them to deal with dynamic situations. In two
experiments, we studied learning behavior in a well-known
dynamic environment called the beer game. Contrary to
previous findings, we found that performance significantly
improved through repeated practice. In the first experiment,
concurrent verbal reports indicated that performance
improved through better utilization of critical information.
Subjects also learned to engage in better future planning by
anticipating changes in the system. In the second experiment,
we provided only information that was critical for their
decisions and found that initial performance was significantly
better, indicating faster learning. It is concluded poor
utilization of critical information and insufficient future
planning are the major factors for learning in dynamic
decision making.
