RationalWiki:Groupthink

All groups suffer the danger of groupthink. To avoid it, an effort should be directed towards being open to criticism while remembering that some people really are cranks. Criticism should be addressed thoroughly, rather than be ignored.

Luckily, we have some diversity of background and opinion here, which helps stop us from going off the deep end with, say, a US-centric or dogmatically atheistic perspective - this helps RationalWiki to remember that there just might be fairies at the bottom of the garden.
