> psychological safety is often used as an excuse for why someone is under performing instead of holding them accountable and helping them

Not in my experience. If management is competent they can help to improve trust between teams and team-members, and create a safe environment for technical discussions.

I always recommend to avoid working for "paranoid" management that sees as "excuses" all complains. Lazy management blames downward their own lacking and creates stress, distrust and problems to the employees that do the work.
