Uncertainty avoidance refers to a society's tolerance for unpredictability and ambiguity. Cultures with high uncertainty avoidance attempt to minimize uncertain situations through strict laws, rules, and safety measures. They also often believe in absolute truths from a philosophical or religious perspective. In contrast, cultures with low uncertainty avoidance are more comfortable with uncertainty and rely more on informal norms and behaviors. The concept of uncertainty avoidance was developed by cross-cultural sociologist Geert Hofstede based on his extensive research of cultures around the world.
