I honestly think social science is only slightly more scientific than astrology.

But even were it not, science is not capable of answering questions like what one ought to do. Sure, A & B disagree; it's interesting why they do; maybe they're both wrong; maybe they're both partially-correct; but what should be done about it? Science can only say what is, not what ought to be.

You have to make some philosophical assumptions (e.g. utilitarianism) in order to even think that science can provide direction, and even then you will get bogged down in questions like, 'what is the greatest good for the greatest number?'

As an aside to the downvoters: don't downvote if you think I'm wrong; please share how you think science can answer a question like 'ought we execute murderers.'
