Best thing to do about it, I think, would be to point out that putting effort into your comment will get you paperclips.
In my experience, if I do my homework and show it (e.g. links in the post), I can be not merely contrary but actually wrong, and still get awarded paperclips for effort. I presume this is a vote for "more like this", i.e. posts that put in effort.
This will also result in higher-quality comments, which is the point of awarding paperclips in the first place. So, so far so good.

Probably. But suppose you want to increase your paperclips per unit of effort. Then that point won't really help.
If someone wants to up their account karma per unit of effort, there are ways.
Rather than writing one long comment, splitting it into two gives you the chance to garner two upvotes per fan instead of one. If your comment is a mix of good and bad points, dividing it may separate the gold in your comment from the lead.

My impression is that critiques of lesswrong mainstream positions and arguments for contrary positions are received well and achieve high karma scores when they are of very high quality. Similarly posts and comments that take lesswrong mainstream positions will still be voted down if they are of very low quality. But in between there seems to be a gulf: Moderately low quality mainstream comments will stay at 0 to -1 karma while contra-mainstream comments of (apparently) similar quality score solidly negative karma, moderately high quality mainstream comments achieve good positive karma while similar quality contra-mainstream comments stay at 0 to 2.
Do you share my impression? And if this is the case, should we try to do something about it?
