How can Engineering leaders create a culture of Psychological safety

To me, your article feels like the first half of a good opinion, but you're missing a crucial second part.

I totally agree it's a good thing to have a culture where capable people feel like they can ask questions and discuss stuff in an intelligent manner without being punished for it.

That said, imagine if there was a doctor that continuously said stuff like "the spleen is directly connected to the ear drum, right?" or an airline pilot that said something like "That round orange light keeps blinking, but I don't remember reading about it in the manual, and the plane's been flying just fine for hours, so it's probably ok to ignore it and let the ground crew figure it out later." Would it be against their psychological safety to question their competence at some point? Would consequences ever be warranted?
