If you believe the magazines and blogs I read, President Obama is “bringing science back”. Apparently like Justin Timberlake he’s reintroducing us to something we might not have realised ever went away.
“Science” in this case is a bit of a problematic term. It doesn’t just mean knowledge resulting from experimentation and examination - it’s used to refer to a whole lot of policies and ethical decisions that are pretty strongly associated with liberal values. Perhaps it’s because of late the Right has been so vehemently opposed to scientific findings (e.g. climate change) we’ve come to associate liberal causes with science. Even when I agree with the policy or approach, I’m slightly concerned by the consequences of conflating the two, particularly when it allows people to leave their own ethics and principles unexamined.
Take one of the most frequently cited examples of Obama’s Scientific Renaissance - stem cell research. Now, removing restrictions on this kind of research could have real benefits and it brings the US into line with most other developed countries. However, the decision whether or not to allow stem cell research is not about science vs religion. It’s about one set of values vs another. Science tells us whether we can experiment on stem cells and what we might hope to find. It doesn’t tell us whether we should. I thought a recent article in Slate summarised it well
That decision rests on whether you think there are any negative consequences to the action, and if so, whether those consequences are outweighed by the potential benefits. It’s about values. I think that in a democracy, the ethical views of the majority should not be outweighted by those of the few, but that’s not the same thing as one set of priorities being “scientific” and therefore inherently more valid.
Or let’s look at climate change. The science seems to me to be unambiguous on the major points, even if many of the detailed predicitions are open to debate. The Earth is getting hotter and will probably get a lot hotter unless we reduce the amount of carbon dioxide in the atmosphere. There are some who debate this, but that’s the scientific question. The question of what we then do about climate change is much less about the science and much more about who is responsible for fixing it.
What costs should we incur now to prevent catastrophe? Who should bear these costs? Do rich countries have a responsibility to act first or should the developing world slow its growth to save us all? These are all questions of values and politics and ethics. There is no scientific solution that identifies what level of wealth is worth sacrificing now to protect our grandchildren. No equation says what a Bangladeshi life is worth in terms of SUV trips to the mall. I believe that urgent and drastic action on climate change by developed nations is needed, but it’s not purely about science.
Maybe it’s because I’m both a social liberal and a Christian that I am especially aware of the tensions. I know that my values and my politics are influenced by so many factors: my faith, my upbringing, my education (five years of economic rationalist indoctrination included) and my career. I know what’s informed by facts and evidence and what’s my gut instinct or sense of what’s right. I may expect you to listen to evidence and proof, but I know that there are many things I will never be able to convince you of because they exist somewhere outside of the scientific method.
Science is often said to be the anthesis of faith and I hear it often. “Oh, I used to believe that, until I discovered science,” a guy commented to me last year. We see a lot of this kind of talk from the New Atheists. Religion is dangerous because it shuts off inquiry and leads to blind obedience, they say. It needs to be stopped. But wait a moment: is that a view backed up by scientific evidence?
I remember watching Richard Dawkins on TV talk about the dangers of faith and it hit me that the moment he talks about religion is the moment he stops being a scientist. Dawkins’ views on religion may be driven by his passion for science, but that’s not the same as being scientific. Has he subjected his hypotheses about the dangers of religion to experimentation? Has he conducted a comprehensive cohort study or a rigorous metaanalysis to see whether exposure to religious belief leads to violence or intolerance or stupidity? Has he determined the causation, controlled for other influences and found a statistically significant variation between believers and atheists? Because until then, he’s squarely in the world of values and ethics and opinion.
I’m pleased to see science taking a strong place in government. I think there should be more of it. I’m all for evidence-based policy and subjecting our presuppositions to scrutiny. I just want everyone to take a deep breath and remember that when a scientist moves beyond what is to what should be, they’re just the same as the rest of us, weighing up the pros and cons and making a judgement. It may be a good thing, but it’s not science.
