If I downvote an answer with 0 votes, it goes down to -1. I changed my mind and I upvote it and it goes up to 1 instead of 0. If I upvote one more time, it goes down to 0.

What's the logic behind this, what I consider weird counterintuitive, behavior?

    I just made your votes go from 1 to -1!

  • It does seem counter intuitive, but consider a question downvoting from 0 to -1. You upvote it after an edit. It goes from -1 to 1. You are essentially cancelling out your original vote as if the downvote never happened. It is one or the other, not both. Jul 21, 2011 at 19:51
  • No hard feelings, it can be confusing.

  • Put your mouse above the vote buttons and read the tooltip. Yes, to undo the vote, just click once again at the same button!

You can't vote both up and down.

When you upvote the post, your downvote is automatically removed.

    This confused me the first time too. I thought that clicking the up button would remove the downvote, but not so. Clicking downvote again removes the downvote. Clicking upvote removes the downvote AND adds an upvote. Jul 21, 2011 at 19:56
  • I am not doing both. What does this even mean logically!? The way I vision this is 0 is between -1 & 1. 1 is above 0 and -1 is below 0 and that's how I operate. Jul 23, 2011 at 4:09

    @Tony: THe furst upvote cancels the downvote; the second upvote cancels the first upvote. The voting arrows are mutually-exclusive toggle buttons.

If you downvote an answer it goes to -1. Your vote isn't instantly finalized and you can only cast one vote per question, so when you upvote it it changes your initial vote of the question to +1. Pushing the upvote button again cancels your upvote and the post returns to it's initial 0.

To add a bit more to these answers, Consider the following:

  1. Click downvote.............Now it's -1.
  2. Click downvote again...Now it's 0.
  3. Click upvote.................Now it's +1.
  4. Click upvote again.......Now it's 0.

Essentially, when you click downvote, and then click the upvote, you are implicitly performing three actions (not just the first two).

The premise here is that it makes more sense to go from -1 to +1 to minimize the number of clicks if you voted in the wrong direction. It might make more sense to change the arrow (up or down) to an X to more clearly signify cancel, but my hunch is that most would rather simply leave the interface unchanged.
