We can change our vote in other websites, but we can't do it in codeforces. So Why? There can't be bad thing by changing our votes.

It forces you to think twice before voting.
Typical counterexample: initially you want to upvote someone. Then it is revealed that this someone was actually lying about something, now you want to downvote. It's important to think twice but you're not expected to have perfect knowledge.
I think most CF users don't think even once before voting.
like just checking the color...
sometimes it's just a mistake that someone touched the wrong button and we should have a chance at least for 10 seconds to undo our vote!
It happens to me almost everytime because I generally browse the blogs on my phone and its too much of a hassle to zoom in everytime I want to click that tiny triangle. :(
Ya same happen with me! Actually I found this blog after I was trying to up vote a comment but I down voted by mistake and I was searching how to undo specially It was a comment that helped me! and it's not fair being unable to undo! __
Yeah. You should know what you want to do clearly before you vote.
@people_above, so editing comments is allowed but changing your vote is not? :D
A reason is likely that it isn't trivial to implement. But yeah, we do need this feature.
Changing a upvote to downvote means adding -2 to the overall votes and vice versa for the second case. How is it difficult to implement.
Contribution is more complicated than just upvotes minus downvotes.
you can see history of a comment
so upvote / downvote must too (0110101)
Also about votes: am I right that I can't easily determine if I've already voted for a post, but can for a comment?
If it's true, why so inconsistent? It shouldn't be difficult to implement.
