How many ideas, innovation, and projects got killed because of groupthink? How many times the assembled crowd made a mockery of the skeptic?
Our organizational system is hierarchical, like christ and his followers. No one dare question the leader and worship him/her and their ideas. If by chance once in a while someone went questioning the ideology, they became an infidel.
Running an organization and innovation requires seeing every side of the coin. Ingroup bias or groupthink affects radical openness. It results in class creation: You fresher, STFU. We know more than you.
Everyone likes sailing with a course of water, very few challenges the unknown. Success depends on knowing all odds and moving beyond groupthink.
We have to avoid falling for CEO disease.
