Groups never admit failure
A group will never admit they were wrong. A group will never admit, “We made a mistake,” because a group that tries to change its mind falls apart. I’m hard pressed to find examples in history of large groups that said, “We thought A, but the answer’s actually B.”Now that is a useful insight.It's a big problem for voluntary associations. Companies can sometimes change their culture, but it usually requires replacing the CEO.This has come up a few times in military history. "L'audace, toujours l'audace" was a WWI French slogan. It took a huge number of casualties before high command got it that charging into machine guns does not work. Courage does not help. In WWII, a big change was discovering that battleships are not useful once the enemy has torpedo bombers. The resistance of the battleship admirals was overcome by Congress, not the Navy. Congress ordered that the captains of aircraft carriers must be qualified to fly aircraft. Sidelining the "Gun Club" took major political effort.Now, the US military is struggling with the "Fighter Mafia", which tends to run the USAF despite the ascendancy of drones and the usefulness of the A-10.
