Geert Hofstede’s “Culture’s Consequences” is one of the most influential management books of the 20th century. With well over 80,000 citations, Hofstede argues that 50 percent of managers’ differences in their reactions to various situations are explained by cultural differences. Now, a researcher at the University of Missouri has determined that culture plays little or no part in leaders’ management of their employees; this finding could impact how managers are trained and evaluated globally.
