The influence of social context and task content on decision making related to risk is studied. Authors used the empirical paradigm of A. Tversky and D. Kahneman: Ss were suggested to make a decision about life or death of risky hypothetic patients suffered from deadly disease. The data obtained showed the cross-cultural pattern of decision-making: people venture more if small group is incurred danger rather then big group. Nationality of hypothetic patients was found to be significant factor of risky decision-making: if patients suffered from deadly disease are of the same nationality as decision-maker then risky decisions dominates over not risky. Conclusion is made that in tasks with the same structure people risk more if decision is made about smb s life rather then money.
