Satisficing is a method for making a choice from
a set of alternatives encountered sequentially when one does not
know much about the possibilities ahead of time. In such
instances, there may be no optimal solution for when to
stop searching for further alternatives. Satisficing takes the shortcut
of setting an adjustable aspiration level and ending the search
for alternatives as soon as one is encountered that exceeds
the aspiration level (Simon, 1956: 129-138; 1990: 1-19). Satisficing
is a form of bounded rationality. For a detailed explanation
of rationality see Gigerenzer, et. al., 1999.
