One reason is that it is very difficult to get good data on what managers actually do on the job. This difficulty is, to some degree, related to the problem of getting access to busy managers; but, perhaps more significantly, it is related to problems associated with the methodological approaches most commonly used by researchers. 36 MANAGERS MANAGING Most data in the social sciences are generated in one of three ways: through surveys, in which individuals are asked what they think, what they know, or what they do; through experiments, in which behavior is observed in carefully constructed situations and through archival research, in which records kept for other purposes are analyzed.
When situations cannot be objectively assessed, individuals use social means to define reality. They rely heavily on cues from others to sort out their perceptions, attitudes, and beliefs (Pfeffer and Salancik 1978). At wine tastings, for example, where indicators of quality are subtle at best, individuals typically write their ratings down. Otherwise whoever speaks first or most articulately is overly influential. Judgments in ambiguous situations are typically not independently made but are a social product.
I do not want to include here all the findings of this research. ) But it might be useful to discuss "availability," one such heuristic that is particularly relevant to managers given their complex and dynamic environment. "A person is said to employ the availability heuristic whenever he estimates frequency or probability by the ease with which instances or associations come to mind" (Tversky and Kahneman 1973, 208). It is, of course, a useful device because instances of frequent events come to mind more readily than instances of less frequent events.
