Is A Rational Nation Ruled By Science A Terrible Idea? (newscientist.com)
Slashdot reader schwit1 quotes an article from Jeffrey Guhin, an assistant professor of sociology at UCLA:
Imagine a future society in which everything is perfectly logical. What could go wrong...? Last week, US astrophysicist Neil deGrasse Tyson offered up the perfect example of scientism when he proposed the country of Rationalia, in which "all policy shall be based on the weight of evidence". Tyson is a very smart man, but this is not a smart idea. It is even, we might say, unreasonable and without sufficient evidence... employing logic to consider the concept reveals that there could be no such thing...
First, experts usually don't know nearly as much as they think they do. They often get it wrong, thanks to their inherently irrational brains that -- through overconfidence, bubbles of like-minded thinkers, or just wanting to believe their vision of the world can be true -- mislead us and misinterpret information... And second, science has no business telling people how to live. It's striking how easily we forget the evil that following "science" can do. So many times throughout history, humans have thought they were behaving in logical and rational ways, only to realize that such acts have yielded morally heinous policies that were only enacted because reasonable people were swayed by "evidence".

Let's compare Science against the philosophies that current rule our societies.
Nationalism? Capitalism? Fear? RELIGION??!
I'll take science....
I think the OP is falling into an anti-science fear-mongering state of mind that misrepresents the core idea of evidence-based policy making. The best thing about science is that it is constantly improvingâ"getting closer to what we might call (with some inherent romanticism) the truth. The anti-science knee-jerk reaction to this is that, because scienceâ"at some given point in its progressionâ"has not yet reached "the truth" then it is wrong and therefore worthless. I argue that there is no better way to move consistently in the direction of truth than the rigorous application of evidence and careful testing that is true science. When it comes to the application of what is learned through the scientific methodâ"a moving target that is constantly improvingâ"to public and governmental policies and laws, there is more than one way to use it, depending on the nature of the government installed. A totalitarian society might tend towards additive applicationâ"creating new laws and rules for society to limit its bounds. A case of "science says this change is optimal so this change will now happen," for example. This is not a methodology that most of us would find comfortable. But in a representative society that values fairness and freedom, such as what we aspire to here in the United States, the application should be of a subtractive nature. Science should be a filter to prevent patently wrong and harmful laws for being enacted and a measuring stick to judge the validity of laws created in more ignorant times. With science-based knowledge continuously improving, something no other form of knowledge acquisition can claim, applying that knowledge to prevent oppressive or dangerous laws is an obvious choiceâ"far better than letting the laws bend to the wills of lobbyists and political powerhouses which have no secure claim to truth or accuracy and, in fact, are often dead-set against them. There is no inherent imperative that science should or would be used to inflict legal restrictions upon American citizensâ"that form of application requires a more totalitarian government. (A form of government that a scientific analysis might steer a society away from.) We should embrace the benefit of scienceâ"more accurate knowledgeâ"and not ignore what we've learned by sticking our heads in the sand and claiming tradition, expediency, selfishness, and ignorance trump truth.
