If people become afraid of pointing out their own mistakes because they will feel humiliated in front of their peers, it’s human nature for them to do whatever they can to hide those mistakes in future meetings. Variances that get glossed over are lost learning opportunities for everybody.

Some tension is unavoidable and appropriate, but we think it’s better to establish a culture where it’s not just okay, it’s actually encouraged to openly discuss mistakes.
