I disagree. Take the education reform problem (in the US). A number of solutions have been proposed, which one should we implement, or should we come up with a new one? Are teachers' ratings completely bogus, as some claim, or can they be used to rate them. People want answers, you can't just give up. Not everybody can close shop and work on other, more well-defined problems because these problems
need to be solved, or lacking that, addressed. You have to come up with a methodology. Now, you may not want to call it "science" but that doesn't make the results meaningless.
Similar problems that require a combination of statistics, biology, psychology, ethics, and politics:
* Should universities stop affirmative action, should they stop reverse affirmative action for Asians?
* Should we (like Norway) enact laws that require a certain percentage of women on company boards?
* Should there be gender equality (in the sense of numbers) in almost all professions? Are men (or women) more suitable for certain jobs?
etc., I'm sure you can think of many more.
