As you can see, Bob, I got hit with a couple of negs, and I can testify that they bite. But then recently I put my big foot into my big mouth, with a very nasty outcome for which I am mortified, so I do feel I deserved those bites. On the other hand, I have broad sholders and a thicker than average skin, so I am able to just laugh this stuff off and carry on.
Hauling my negative rep around is like Marley’s ghost, cursed to drag his chain up and down those stone stairs year after year.
All the same I won’t try to deny I have a vested interest in this, but it is really only a very small one, since personally I don’t take it that seriously.
However, from a psychological perspective, having the negative option is actually a bad idea.
The positive rep option and the Thanks button are both good. The neg thing is going to hurt thin-skinned people, which is to say, most folks. It also gives the mean-spirited a ready way to strike out at someone with anonymity and impunity. Getting hit by a neg can be very discouraging, and may even drive some members away from your site. The Neg button puts a very ugly weapon in the wrong hands. Personally I would never use it under any circumstances. Even one neg rep it could spoil someone’s whole day.
And it will not improve anyone’s outlook or behaviour, so there’s absolutely nothing to be gained by it.
Meanwhile, seeing that they can earn good rep points will encourage people to try to behave better.
Knowing what I know of psychology, which is quite a lot, actually, if I were in your shoes I wouldn’t try to fix the neg button.
I’d just remove it.
