Answer to: Is ritualized confession a sign of a bad culture of failure?

That depends a bit on why there are doing it. Mistakes can be painful and costly but they are also a prime learning opportunity. Hence, there are plenty of formal methods of dealing with mistakes and, yes, openness and lack of blame are key ingredients and first steps. But this should be followed by "what have I/we learned?", "what will I/we doing differently going forward?" and "what specific actions will we take and what specific changes will we implement so this will never occur again?" and creating a plan to track and execute these steps. Maybe your company does follow a formal process for this, which would explain that it feels "ritualistic". In that case, it would not be a ritual, but everyone just follows the same set of defined steps. I would check with your manager and/or company handbook. So the key question for me here would be: Does the mistake handling process includes a learning/documentation component that helps others avoid the same mistakes and prevents occurrence of the same or similar issues? Self-bashing without learning would seem silly to me. One of my managers summed it up like this: "You can make any mistake, but don't make the same mistake twice".
