There is a problem with what is called the "donkey vote" where the person at the top of the ballot is more likely to get a "1" vote than the person at the bottom. However, in practice, people accept voting guides from parties that direct their preferences and they vote the way their choice of party decides. That's why there is horse trading between parties before the election on "preference deals" where they agree to different ordering on the guides. Smaller parties use this to engage larger parties by demanding some of their policy requests in return.
