The authors replicated O. Ostberg's (1980) study of forestry workers using a range of personnel groups in coal mines. Findings demonstrate a high level of consensus between a range of personnel groups for a set of pictorially depicted behavioral risks, at the level of rank order, but significant differences in terms of relative magnitudes. Magnitudes of perceived risk were found to be greater for those closest to the point of hazard than for members of more geographically and experientially distal groups. Findings are interpreted with reference to experiential influences associated with organizational role. Revealed differences between personnel groups are explained in terms of cognitive availability, specifically effects associated with habituation and familiarity with risk, these sources of perceptual bias appearing to interact with organizational role.
