Rocha's statement captures a subtle but crucial aspect of the psychology of speaking up at work. Consider his words carefully. He did not say, “I chose not to speak,” or “I felt it was not right to speak.” He said that he “couldn't” speak. Oddly, this description is apt. The psychological experience of having something to say yet feeling literally unable to do so is painfully real for many employees and very common in organizational hierarchies, like that of NASA in 2003. We can all recognize this phenomenon. We understand why his hands spontaneously depicted that poignant vertical ladder. When probed, as Rocha was by Gibson, many people report a similar experience of feeling unable to speak up when hierarchy is made salient. Meanwhile, the higher ups in a position to listen and learn are often blind to the silencing effects of their presence.
