Groupthink is the tendency to make decisions based on consensus, even if, individually, group members may find those decisions to be weak. Thankfully, there are a lot of ways to avoid groupthink. There are new and powerful ways to teach people to be better, more independent thinkers. For one, people should be encouraged to play the devil’s advocate and help break up the norm of agreement. Along the same lines, people with a dissenting opinion should be encouraged to speak up, without negative consequences, so long as their opinion is fact-based and well-researched.
