I think you have it backwards; psychological safety is something that executive leadership has to build into the culture of the company. What it comes down to is a culture where decision making is transparent, questioning the status quo is encouraged and no one person holds the power to make / break a product. At the team level you’re always going to have good managers and bad managers, but with the right culture the bad managers blast radius will be diminished. A good manager can’t do a whole lot to overcome a shitty culture.
