"Do people work harder in groups or as individuals?" is not a yes/no question. It's a question they study, but they're not looking for a simple answer.

That is my point, it's a complex question with multiple possible answers. But the test the study is based on reduces it to a binary problem.

After glancing through the study I don't see where it does that?
