Is is not Ought

The killing of Osama bin Laden and the ensuing controversy over the widespread jubilation in the U.S. have prompted some scientists to explain the psychological and evolutionary basis for those celebrations. Unfortunately, some of them used science to argue that since joy in this situation is natural, it is also morally good. Regardless of one’s view on the appropriateness of celebrating a killing, the fact that it is natural to do so has no relation to whether it is moral or right. Science bases human behavior on the functions of neural networks and evolutionary adaptations, but does not excuse us from taking responsibility for those behaviors. Just as promiscuity may be a natural but not morally inacceptable temptation for males in a monogamous society, natural joy over the killing of an evil man is not necessarily good either. Our values come from philosophy, not empirical evidence. Or, as Hume wrote, what is is not necessarily what ought to be.

That does not mean that science and morality have nothing to do with each other. While it is illogical to justify a value using scientific facts, as some did with celebrations of Osama bin Laden’s killing, it is quite alright to use science to optimize the practice of an established value. If we deem it unacceptable to celebrate killing, we may use neuroscience to adjust educational techniques to instill that value in our children.

Most importantly, science writers have a responsibility to separate facts from values; what behavior is natural and what behavior is acceptable. They must be careful to note that a materialistic basis for mental events does not relieve us from responsibility for our actions. At the same time, readers must be wary of those who try to use scientific evidence to justify a moral agenda. Science alone will never be a basis for our values, but if used properly, it can help us realize the values we choose.

"Why we celebrate a killing," by Jonathan Haidt and my response.

Extra extra!!! Storm brewing in espresso shot!

The media is always hungry for juicy stories about anything. Topics of interest range from Lindsey Lohan's latest adventures to the implications of another political ethics violation. The science writers at the New York Times are no exception. Dennis Overbye confessed in an essay yesterday that some writers are so eager to report on sensational findings that they sometimes hype up their stories.

Shocking! Overbye gives an example of one such NYT article, which reported the amazing story that scientists found hints of the elusive and mysterious dark matter in a Minnesota mine. He said the article raised a hysteria, but it eventually left people disappointed when someone cared to report that the amount of dark matter found was not far above amounts found by chance. Dennis Overbye goes on to condemn the internet for spreading rumors, but he fails to note that the original hyped report on dark matter was written by him!

Perhaps our trusted science writers should do a bit more research before they publish their articles. But wait! they need the stories, and they need those stories to be catchy, damnit! Their job isn't to educate readers on the current state of whatever scientific field; their job is to report the latest findings. They more controversial they are, the better. There's a new article everyday about how exercise is good for you (or is it bad? I can't remember anymore) or how prostate or breast exams for cancer have been wrong all these years (don't worry - they'll turn out to be right again next week). No wonder Americans are confused about their health.

Individual studies are great, but they have to be taken in context and have to stand the test of time. Most findings in basic science research are small; it's the knowledge collected over many experiments and years that gives us a big picture of any one field. So the next time you read about "a new study," take it with a critical grain of salt.
