There are varying explanations that attempt to provide a reason as to why groupshift occurs. • Group diffuses responsibility: a diffusion of responsibility throughout the group seems to give members of these groups a free rein to act as they see fit (Wallach, Kogan, & Bem 1964). The emotional bonds that are created within the group serve to decrease anxiety within the group and the actual risk of the situation seems less. • Brown (1965) indicates that social status in groups is often associated with risk-taking, leading people to avoid a low risk position. • Collins and Guetzkow (1964) suggested that high risk-takers are more confident and hence may persuade others to take greater risks. • Bateson (1966) suggests that as people pay attention to a possible action, they become more familiar and comfortable with it and hence perceive less risk. The size of the group also has an effect on how susceptible the group will be to polarization. The greater the number of people in a group, the greater the tendency toward
deindividuation. In other words, deindividuation is a group-size-effect. As groups get larger, trends in risk-taking are amplified. Scientific research also suggests that males are greater risk-takers than females (Wilde 1994) a trait that likely has both physiological and social roots. Numerous accident statistics support this assertion. For example, in the period 1984–1996 in Canada, 90% of avalanche fatalities were male (Jamieson & Geldsetzer, 1996). == Using the risky shift==
