1. Create culture where anyone who steps outside the political or moral norm is fired/career limited. 2. Sneer about no "professional sources" for positions, since few people value ideas over employment/tenure. Only people with nothing to lose publically air those opinions, those with things to lose keep them to themselves. 3. Imply that anyone who thinks in the non-approved way must be like those people/undesirables with nothing to lose, despite the silent ones having a lot to lose. You can say this is all tinfoil, but my engineering ethics professor told the entire class he's had to make choices between "speaking truth to power" and his career and that in the interest of full disclosure he chose his career + funding. 250+ people in that room at the time.
