I was reading the answer to this question and I find it very useful, agreeable and constructive: How can I get my question reopened as someone answered in the comments?
ChrisF states very clearly what an user of this community should do. But it's completely on the user side, there is nothing about what the moderators should do.
Of course this is given as understood, treated in other places, and moderators here are doing a great work! But since this community is very ambitious, mature and tries to improves itself I would suggest another point.
Moderators are working hard, are doing their best, but this is an ambitious, technical community which tries to be constructive and scientific. And psychology and sociology have clearly studied the attitude of people to consider their own opinion as true. And not really put it into discussion.
Being aware of the limitation on our objectivity is an important step for someone who is called to administer "objectively" and supposed to be fair.
So as we find what users should do, I think it's fair to find what moderators should do. And work on their psychology, on their human-physiological bias could be important.
Do you think moderator should make an effort and read these 2 articles?

(ps: this discussion may be probably seen as polemical and OT, but - true or not - if this adjective becomes an excuse to avoid taking it into consideration to make a work on ourself, this is a perfect example of rationalization: finding an excuse to justify our behavior, to confirm our ideas, to avoid putting ourself into discussion and putting effort in something which we don't like)
