Imagine walking into a room where saying “I don’t know” doesn’t make you shrink. That kind of ease – when speaking your mind won’t backfire – is what people now call psychological safety. Teams thrive when members can question things, even challenge decisions, because they believe no one will mock them later. Instead of just getting along, it’s built on real listening and mutual regard. Mistakes show up not as failures but as chances to learn, since blame stays out of the picture.
