Context: web application.
I have a list of items, each one with up and down arrows (a la reddit) but my list doesn't shows the most up-voted items, but the most down-voted (technically it's ordered with up/down votes ratio).
I think there's a fundamental issue here. If you have an ordered list with arrows alongside each item, you'd expect the item to go upper in the list if you up-vote it. But what would happen is exactly the opposite, making the item go down.
I thought about replacing the arrows with thumbs (to take away the expectation of an item following the direction of the arrow you just clicked) and making explicit right there in the list that the order is based on down-votes, but I don't like this at all.
How can I make this behavior more understandable? Maybe another form of representing the data? I'm open to any ideas.
