Look, I am speaking from personal and anecdotal experience, however its so blindly obvious for myself and coworkers. The amount of dissonance between my beliefs and my actions at work feels like a micro scale version of what life would be like under a surveillance state. The difference in openness between the two large groups of people that have opposing views at work are massive. Both groups have smart people, both groups have good intentions, the ones that are silent are not silent because they hold chauvinist views, they are silent because the other side is actually bigoted.
I wish you could do a study on it, but you can't right now.
