In an experiment in which German and American teams attempted to reach consensus on a complex task,

Compared to the U.S. teams,

the German groups generated 30% fewer statements focused on possible solutions

and more than twice as many statements focusing on various problems, such as inadequate information.

The findings suggest that, culturally, Germans tend to desire a substantial amount of background information before making decisions and prefer clarity over uncertainty, whereas Americans tend to quickly come up with solutions, often without having a complete and thorough analysis of the problem.
