They tend to be pretty abstract ones then, like doing what will have the best consequences; obviously you wouldn't specify what consequences are best, they may be different in some circumstances, so at a lower, more specific level, you may well get differences.

To be a utilitarian means that you judge actions as right or wrong in accordance with whether they have good consequences. So you try to do what will have the best consequences for all of those affected.
