In case some of you don't know the definition of Groupthink, I'll save you the trouble of Googling it. Here's a description from Psychology Today:
"What Is Groupthink?
Groupthink occurs when a group of well-intentioned people make irrational or non-optimal decisions that are spurred by the urge to conform or the discouragement of dissent. This problematic or premature consensus may be fueled by a particular agenda or simply because group members value harmony and coherence above rational thinking. In a groupthink situation, group members refrain from expressing doubts and judgments or disagreeing with the consensus."
So in a nutshell, If you actually possess critical thinking skills and the ability to make your own decisions, you will be shouted down and scolded by the mods on this site. And in the end you'll probably be banned anyway.
