2. introspectively active (and accurately so) over a long enough period to notice that they behave differentially in public and private contexts

Humans are primitive. Questionnaires have to be designed around that.
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.
