People with high uncertainty avoidance.
People with high uncertainty avoidance tend to have a lower tolerance for ambiguity, and as a result, they are not as open to new ideas and opinions that differ from their own. They prefer structure and stability and tend to be risk-averse. Uncertainty avoidance is one of the dimensions of Hofstede's cultural dimensions theory, which compares national cultures across six dimensions: power distance, individualism-collectivism, masculinity-femininity, uncertainty avoidance, long-term versus short-term orientation, and indulgence versus restraint. Therefore, the correct answer is People with high uncertainty avoidance.
