Why did my question about Fibonacci Sequence get closed in spite of having 10 more upvotes than downvotes? Don't those upvotes mean the vast majority of users think that question is on-topic?

    $\begingroup$ I'd guess both (specific-question) and (on-topic) would be suitable tags here. Perhaps (closed-questions) might be a reasonable tag, too. (I will mention that the question was among the hot network questions. Which means that at least some part of the upvotes probably came from users outside the MathOverflow community. The question is in the reopen review queue at the moment.) $\endgroup$ Sep 19 at 12:37

    $\begingroup$ "Don't those upvotes mean the vast majority of users think that question is on-topic" - this makes an assumption that most users vote. I think it is much more likely that the number of positive-or-negative votes is far lower than the number of people who have looked at the question.off-topic $\endgroup$

    $\begingroup$ As for the question itself, it seems rather borderline between MathOverflow (questions arising in mathematical research) and our sister site MathStackExchange (for general mathematics). Sridhar Ramesh points out in a comment that the behaviour you observed seems to be caused by a programming/computer issue and hence does not reflect the true mathematical behaviour of the Fibonacci sequences $\endgroup$

    $\begingroup$ An observation like yours on the number of ones in the binary representation of Fibonacci numbers looks so implausible that before even starting to believe it, one normally would do a number of checks, including checks whether the observed behavior is caused by an artifact of the implementation (as it was the case here). Upvotes to a question like this should not be overrated, as the question is quite clickbaity, and via the association bonus even many people without any posts on MathOverflow can vote. $\endgroup$

    $\begingroup$ On this site, upvoters have a bias towards upvoting questions and answers that are easy to understand. $\endgroup$ Sep 19 at 21:13

    $\begingroup$ The fact the question had a large number of downvotes (currently 8, not sure what it was when closed) is more informative than upvotes, which for easy-to-understand questions is more of a "I understand this, and like that fact" measure of users not all from MO. $\endgroup$
