Or in other words dumb people are less impacted by social desirability bias when responding to the survey because they don't realise that 'impartiality' is something to be desired.

As for why impartial news does so poorly in practice, it's often because it's utterly uninformative. 'Car bomb goes off in Kabul' is worthless info to 100% of the population, whereas the moment you try to contextualise it 'Car bomb goes off in Kabul, which is becoming more frequent, which suggests administration is lying about how well the occupation is going' then you're no longer impartial.

Journalists and editors have spent the better part of a century stripping all useful information out of their articles in an effort to be impartial. It would be much better if they instead aimed for a diversity of opinions than a mythical objectivity devoid of ideological bias.
