Economics writer Tim Harford argues that the only way to succeed in problem solving is to try and fail. Harford argues that too many people are suffering from the “God complex,” thinking the nation’s smartest experts can devise plans to solve difficult problems.

During a TED address in July, Harford says that even with the large volumes of data we are able to obtain, there are some problems, like the economy, that are too incredibly complex for us to understand.

Counting every product and service offered in New York alone would take 317 years, so the only thing humans can do, Harford says, is to rely on trial and error.
