  Another problem with the weighted priority view is that it pays no direct attention to horizontal fairness between people, in the following sense: we think that if two people begin in the same condition of need—say they have sustained similar injuries—there is value in their receiving treatment that gives them the same outcome, so long as this is feasible and not excessively costly. But the weighted priority principle cannot ensure this, since it has a bias in favour of the victim who can be treated at lesser cost; by choosing to treat that person rather than the equally needy other, more needs overall can be satisfied. So although there might be exceptional cases in which we are willing to practice a form of triage, because we can see that treating John’s needs will have opportunity costs that are simply too high, the weighted priority principle risks taking us too far in that direction.
