If a large collection of diverse individuals is likely to contain either a single superior solution to a problem, or on average, the collection will be correct, what would be an appropriate approach to decision making?

A) Evidence-based management
B) Crowdsourcing
C) Big data
D) Analytics
E) Stimulate controversy

Crowdsourcing leverages the collective intelligence of a large group of diverse individuals, which aligns with the scenario described. It is an approach where problems are solved or tasks are performed through the contribution of a vast, diverse crowd of people, rather than relying on traditional employees or suppliers. This method is particularly effective when there's a belief that a large, diverse group is likely to come up with a superior solution or that, on average, the group's collective answer will be correct.
