A policy choice is the linkage of a fact to a particular goal; while few policy choices are so simple as to admit of a binary choice, you can certainly rank them on a gradient.
Of course, it helps if your goal is clearly definable and you maintain awareness of consistency. Otherwise, a goal of, say, improving life expectancy might be satisfied by a eugenics policy which made unpersons of those with medical conditions that would lower life expectancy.
But a goal cannot objectively be right or wrong. It could be agreed upon, but it can never be true in the sense that objective facts are true.
To go even further, people may agree on the 'what' of a goal, but disagree on the 'why' of a goal, which very much inform what policy choices they are amenable.
