We can use the [Data Explorer](https://data.stackexchange.com) to see how often we up- and downvote. [This query](https://data.stackexchange.com/mathoverflow/query/1359832/vote-statistics-per-site) 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 #35 for downvotes.

We can't use SEDE to measure how *fast* we downvote; see https://meta.stackexchange.com/q/933/295232 for details.
