" Psychological safety is broadly defined as a climate in which people are comfortable expressing and being themselves. More specifically, when people have psychological safety at work, they feel comfortable sharing concerns and mistakes without fear of embarrassment or retribution. They are confident that they can speak up and won't be humiliated, ignored, or blamed. They know they can ask questions when they are unsure about something. They tend to trust and respect their colleagues. When a work environment has reasonably high psychological safety, good things happen: mistakes are reported quickly so that prompt corrective action can be taken; seamless coordination across groups or departments is enabled, and potentially game-changing ideas for innovation are shared. In short, psychological safety is a crucial source of value creation in organizations operating in a complex, changing environment. "
