O.K, so I have at times shown an ugly side of my personality when posting angry comments when being downvoted, and having had the impression that the votes were undeserved.
I understand that it is not good for the health of MSE to have "false positives", i.e., posts that have incorrect answers, and that downvotes are a disincentive to these false positives. Still: how about the problem of false negatives? By this I mean posts that have been downvoted so that they have a net negative score, but these posts have been eventually corrected. Is this something helpful to MSE ? Doesn't this deprive some of the opportunity to learn from posts that are actually correct, believing that there are errors from the net negative score?
I have to admit I am upset too, at the lack of effort to post a comment of the sort of "please check, you got something wrong in last line of 2nd paragraph", and waiting to see if the OP has corrected the mistake(s), and downvoting only if these have not been corrected. Moreover: isn't there an issue of fairness in having downvoters return to the OP to check if the post has been corrected and , if so, removing their downvotes? This last would not only be fair, but it would help rid MSE of false negatives --if, that is, MSE does not want these false negatives.
EDIT: Could we have a truce? I admit it, I blew up, reacted in a way disproprtionate to the situation. My apologies if I came off too aggressively. Still, just to explain, I received 5 downvotes on old questions in less than 24 hours after I did this meta post. How can one interpret this? O.K, so the tribe has spoken :) , I accept that most people do not agree with me, and I do not want to impose my will. I thought I had a valid point, but it seems more likely I don't.
