“…There has been little previous research in this area and, as such, not much is known about the effects of groups size and alcohol-related risk-taking in different environments. However, research in support of the 'risky shift', where groups appear to engage in riskier choices than individuals (Isenberg, 1986;Moscovici & Zavalloni, 1969), does suggest that such effects are pronounced as group size increases (Teger & Pruitt, 1967), supporting the current findings in the non-alcohol-related environments. The absence of group size influences in the SU bar environment, may therefore in part be understood through alcohol myopia explanations, whereby intoxication causes focal narrowing (Steele & Josephs, 1988;Steele & Josephs, 1990), resulting in reduced attention towards group size.…”
