Dear PG, please allow reversal of upvotes.
The simple fix of allowing one to take away a previously given upvote might easily improve the signal-to-noise ratio here.

I think this "fix" would be used mainly by people who feel uncomfortable when they see assertive and well-written comments that disagree with them, and therefore it would hurt the signal-to-noise ratio. True mistakes are rare, no more than 5% of total votes. That's negligible for this context. It would be much worse to let people fix their votes after realizing the social context of their opinion.
I like this idea because I've clicked the wrong arrow on more than one occasion.
It's galling to try to mark a comment as stupid and instead end up giving it my seal of approval...and vice versa.

I agree. It would also be consistent with other interaction on the site -- e.g. allowing you to modify or delete comments for a limited period of time.
I should be interested to hear a well argued explanation on "signal to noise" reduction following the introduction of "Upvote Reversal". The benefits are not immediately obvious to me.
You've never once clicked the up arrow by mistake?
I've definitely done this, too. And I do tend to get mad at myself - but it is exactly that: mad at myself for making a clumsy mistake. If you start designing things to handle peoples' occassional mistake, you run a real risk of ending up with something bloated and clunky.
I enjoyed your manifesto on why seatbelts in cars are bloatware.
I'm not sure whether you are praising colins_pride or making fun of him.
Car safety is one of the canonical examples of the "risk compensation" effect:
"In 1981 John Adams published a paper, The efficacy of seatbelt legislation: A comparative study of road accident fatality statistics from 18 countries, Dept of Geography University College, London 1981 - published in 1982 by the Society of Automotive Engineers. This showed that in the countries studied, which included states with and without seat belt laws, there was no correlation between the passing of seat belt legislation and reductions in injuries or fatalities.
This paper was published at a time when Britain was considering a seat belt law, so the Department of Transport commissioned a report into the issue. In the event the report's author, Isles, agreed with Adams' conclusions. The Isles Report was never published officially but a copy was leaked to the Press some years later. The law was duly passed and subsequent investigation showed some reduction in fatalities, the cause of which could not be conclusively stated, due to the simultaneous introduction of evidential breath testing.
Other research has taken groups of drivers, including those who did and did not habitually wear seat-belts, and measured the effect on driving style in the habitually unbelted. The drivers were found to drive faster and less carefully when belted."

I'm still going to wear my seatbelt.
Safety systems to save human lives in rare but catestrophic events are just not the same as adding code - and more importantly design complexity - to handle the odd mis-click where the most profound consequence is frustration on the part of the individual who made the mistake.
Ultimately I think it just comes down to how minimalist your design philosophy runs, and I'd be quick to admit that mine is more minimalist than most.

I can hardly imagine that adding a down-arrow triggered by having previously pressed the up-arrow would require more than a few simple lines of code.
I don't think the reason this is not in is because of the number lines of code. You are correct, it would probably be trivial. But, the ability to reverse a vote, unless restricted to a very short period, would encourage group think and certainly wouldn't reduce the signal to noise ratio as you originally claim.
The number of mistaken up votes is probably a very tiny percentage of total votes, and accidental votes from multiple users on the same comment or post are most certainly even more rare. So the odds any given 'noise' comment or post is accidentally upvoted up to a meaningful level are extermely low.
And group think is already a problem on any voting news site. Allowing people to change their vote after they can see how everybody else is voting would certainly not alleviate that problem.
So while allowing a change of vote would help out an individual on their rare case of accidental upvote or downvote, I think the overall community effect would be detrimental.

What about limiting the reversal to a short time span, say 1 minute?
How about PG adds vista style confirmations? :)
This would have to expire after a certain period of time, or else it will simply become a downvote. I can imagine someone making a pool of bots who randomly upvote some fraction of all comments, which will build up a pool of votes which can be punitively taken away.
Wouldn't it be simpler to just move the up/down vote buttons farther apart to reduce the number of errors? The comments here suggest it's a UI problem not "I changed my mind."
