Answer: True
Step-by-step explanation:
Uncertainty avoidance refers to the difference in cultures based on the tolerance level that they have when it comes to unpredictability.
People in cultures that has high uncertainty avoidance minimize unforeseen or unknown circumstances and have rules in place which will help in mitigating the risks. On the other hand, low uncertainty avoidance cultures are quick to accept changes and have few rules.
Therefore, the statement that "Cultures that often create systems of formal rules as a way to provide more security
and reduce risk are called high-uncertainty-avoidance cultures" is true.
