Final answer:
Cultures with high Uncertainty Avoidance Index scores tend to experience greater anxiety and stress and have a heightened concern with security and adherence to rules.
Step-by-step explanation:
Cultures with high Uncertainty Avoidance Index scores are known to have a higher level of anxiety and stress, coupled with a preoccupation with security and adherence to rules. The Uncertainty Avoidance Index is one of several dimensions that Dutch social psychologist Geert Hofstede identified to describe how societies cope with the fact that the future can never be known: cultures high in uncertainty avoidance have a low tolerance for ambiguity, which engenders higher levels of anxiety and a need for formal rules and policies. In contrast, cultures with low uncertainty avoidance are more tolerant of the ambiguity of life and are hence less stressed by unknown situations.
The other options given, such as Power Distance Index and Individualism/Collectivism Index, describe different cultural dimensions. Power Distance Index pertains to the extent to which less powerful members of societies accept that power is distributed unequally, and the Individualism/Collectivism Index reflects the degree to which people in a culture are integrated into groups and the importance of individual vs. collective well-being. These dimensions do not directly correlate with societies’ levels of anxiety and need for security as posed in the question.
