The main lesson of aircraft safety culture should be that you can have an enquiry to establish what happened, or an enquiry to find out who's to blame - but not both, since once you start assigning blame there's a motive to conceal or destroy evidence.

> no secrecy

This is a nightmare for the person who's percieved underperforming due to unavoidable health issues that they've discussed with their manager/HR but would prefer to keep secret.

> social pressure to confess errors

This turns into bullying very quickly.
