We can use the Data Explorer to see how often we up- and downvote. This query compares the number of posts (including deleted ones) and the number of up- and downvotes for all sites in the network. On MathOverflow, a post receives (on average) 5.29 upvotes and 0.46 downvotes. Of the 176 sites in the network, we're #23 when it comes to upvotes per post, and #...

What is the benefit to later readers in seeing the vote counts on answers A and B? Questions on ME sites are supposed to be interesting for non-expert readers as well. A layperson benefits from reading an answer that hits the nail on the head (at least more than from reading one that misses the nail entirely) but may not be able to recognize such an answer &...

You wrote when I ask a question on MathOverflow, or any StackExchange Site, and I either upvote or downvote an answer written by a high-reputation user ... I very frequently get a corresponding upvote or downvote on my question shortly thereafter. It's not clear from that phrasing whether the answer you upvoted is to the question on which you receive the ...

I agree with Scott. .

What is the benefit to have such a system at all? For each question, there are many perspectives on it. Various presentations can reach wider audiences, if they are on topic, well written, and show some degree of relevance. The StackExchange platform is intended to encourage good questions that others can use, as well as good answers to those questions. ...

There's a meta stackexchange thread on this topic, here: Cancelling upvote on comment?. In brief, you can change your mind -- "upvoting" again undoes the upvote -- provided that you do it quickly (within 60 seconds) and without navigating away from the page. Otherwise, no, you can't take it back as far as I'm aware. It would be nice to not have to decide ...

I messed around a little with the spreadsheet. https://docs.google.com/spreadsheet/ccc?key=0AkdAf5FqZ2CBdDJfdDFvVXFuSkxYQU1YeFpJaVM0MlE&usp=sharing My new columns are: ratio of votes/external votes. (Note that i used the quotient function which rounds the quotient to the nearest integer) comments. In the comments i was concerned about questions with ...

Here are some additional SEDE queries. (As my knowledge of SQL is rather limited, take all of this with a grain of salt.) Percentage of Upvotes and Percentage of Upvotes (multisite). MathOverflow currently gives 91.94%. We can obtain average number of up/down-votes on post which weren't deleted if we look into table Posts rather than PostsWithDeleted. (But ...

Users cannot see who voted on things. It is physically possible but extraordinarily unlikely that someone is monitoring your vote count and correlating that with her/his score. Moderators can see some voting information, but I don't think it would be proper to spell out the details. You may be seeing correlations for the following reason: When an old ...

Here is a spreadsheet with more extensive data on the 385 posts with at least two "external" votes. https://docs.google.com/spreadsheet/ccc?key=0Avlld30uD7CodHdLVmJUUV90RHlSSkVTVVVydmtOc1E&usp=sharing The columns are: Post ID. Total post upvotes minus downvotes (regardless of origin). Total post upvotes from users whose only points are from the ...

Thanks that you brought this question up again. The only answer for the question that you have mentioned was from François. And, if I understood his argument correctly, the main reason behind up-vote/down-vote system on meta is to bring the valuable questions to the top of this list. If we accept this, we can go with Stefan's suggestion and make the voting ...
