From a recent McKinsey Quarterly comes this interesting tidbit:

A recent survey by McKinsey asked about decision-making practices and compared them with decision outcomes. Decisions that were made after a company’s executives sought out contradictory evidence and opinion were more likely to turn out well.

By getting away from the groupthink that pervades many decision making processes – and seeking out opinions from a diverse range of people – you get better outcomes. The takeway from this?  Broaden your thinking, embrace different mindsets and seek out fresh trains of thought.
