I was thinking a bit ago that I down vote a lot, so I checked my current numbers on Stack Overflow, and they surprised me:

1965 up : 1428 down

I doubt I would qualify for the supreme Grinch award here, but I'd guess I am quite a bit out of the norm as far as how many down votes I have, compared to up votes.

Does anyone have a query handy that could shed some light, or have anecdotes about users with low (high?) ratios?

I would guess that there are far more users with lots of up votes and very few down votes than the reverse.

p.s. I'm really not the old curmudgeon(sp?) my voting might suggest!

p.p.s. I think I should be voted on this question in equal proportion to my voting ratio!

p.p.p.s. My voting ratio on meta is much "nicer": 1098:276

EDIT:

I'm also curious about the average ratio. My wild guess would put the average at about 8:1 or even 10:1. I get the feeling that more casual users will tend to down vote very rarely, and the voting habits of casual users will add up more than active ones, simply due to numbers.

An average of "more active" users would be interesting to see as well. Of course, the criteria to apply there would be up to the query-er. Perhaps number of days logged in to the site (that is, number of days as counted by the Fanatic badge; though not consecutive, for these purposes)
