I’ve visited Singapore a few times in recent years and been impressed with its wealth and modernity. I was also quite aware of its world-leading programs in mathematics education and naturally noted that one of the candidates for president was Tony Tan, who has a Ph.D. in applied mathematics. Tan won the very close election and joined the government of Prime Minister Lee Hsien Loong, who also has a degree in mathematics.

China has even more scientists in key positions in the government. President Hu Jintao was trained as a hydraulic engineer and Premier Wen Jiabao as a geomechanical engineer. In fact, eight out of the nine top government officials in China have scientific backgrounds. There is a scattering of scientist-politicians in high government positions in other countries as well. German Chancellor Angela Merkel has a doctorate in physical chemistry, and, going back a bit, Margaret Thatcher earned a degree in chemistry.

One needn’t endorse the politics of these people or countries to feel that given the complexities of an ever more technologically sophisticated world, the United States could benefit from the participation and example of more scientists in government. This is obviously no panacea — Herbert Hoover was an engineer, after all — but more people with scientific backgrounds would be a welcome counterweight to the vast majority of legislators and other officials in this country who are lawyers.

Among the 435 members of the House, for example, there are one physicist, one chemist, one microbiologist, six engineers and nearly two dozen representatives with medical training. The case of doctors and the body politic is telling. Everyone knows roughly what doctors do, and so those with medical backgrounds escape the anti-intellectual charge of irrelevance often thrown at those in the hard sciences. Witness Senator Bill Frist, Gov. Howard Dean and even Ron Paul.

This showing is sparse even with the inclusion of the doctors, but it shouldn’t be too surprising. For complex historical reasons, Americans have long privately dismissed scientists and mathematicians as impractical and elitist, even while publicly paying lip service to them.

One reason is that an abstract, scientific approach to problems and issues often leads to conclusions that are at odds with religious and cultural beliefs and scientists are sometimes tone-deaf to the social environment in which they state their conclusions. A more politically sensitive approach to problems and issues, on the other hand, often leads to positions that simply don’t jibe with the facts, no matter how delicately phrased. Examples as diverse as stem cell research and the economic stimulus abound.

Politicians, whose job is in many ways more difficult than that of scientists, naturally try to sway their disparate constituencies, but the prevailing celebrity-infatuated, money-driven culture and their personal ambitions often lead them to employ rhetorical tricks rather than logical arguments. Both Republicans and Democrats massage statistics, use numbers to provide decoration rather than information, dismiss, or at least distort, the opinions of experts, torture the law of the excluded middle (i.e., flip-flop), equivocate, derogate and obfuscate.

Dinosaurs cavorting with humans, climate scientists cooking up the global warming “hoax,” the health establishment using vaccines to bring about socialism – it’s hard to imagine mainstream leaders in other advanced economies not laughing at such claims.

Often too interested in politics as entertainment, the media is complicit in keeping such “controversies” running. Doing so isn’t hard since vivid, just-so stories and anecdotes usually trump (or should that be Trump) dry, sometimes counterintuitive facts and statistics.

Skepticism enjoins scientists — in fact all of us — to suspend belief until strong evidence is forthcoming, but this tentativeness is no match for the certainty of ideologues and seems to suggest to many the absurd idea that all opinions are equally valid. The chimera of the fiercely independent everyman reigns. What else explains the seemingly equal weight accorded to the statements of entertainers and biological researchers on childhood vaccines? Or to pronouncements of industry lobbyists and climate scientists? Or to economic prescriptions like 9-9-9 and those of Nobel-prize winning economists?

Americans’ grandiose (to use Newt Gingrich’s malapropism) egalitarianism also helps explain why the eight or nine original Republican presidential candidates suffered little for espousing, or at least not clearly opposing, scientifically untenable positions. Jon Huntsman, the only exception, received excessive kudos for what seems a rather lukewarm acceptance of climate change.

To avoid receiving the candidates’ canned responses on these and other issues, I sometimes wish that a debate moderator would forgo a standard question about immigration or jobs and instead ask the candidates to solve a simple puzzle, make an elementary estimate, perform a basic calculation.

Of course, the other side of the “two cultures” chasm should bear some of the onus for this lack of communication between politicians and scientists. Too few scientists are willing to engage in public debates, to explain the relevance of their fields clearly and without jargon, and, in the process, to risk some jeering from a few colleagues. Nevertheless, American scientists do more on this front than those in most other countries.

Perhaps because the words rhyme, it’s sometimes said that attitude is more important than aptitude in helping to bring about innovation, economic progress and social change. The dubious corollary is that freewheeling Americans who question authority and think outside the box have an abundance of attitude that helps make up for a declining performance in science and technology.

Maybe so, but attitude can only go so far. There is certainly no requirement for a Singaporean science background, but scientifically literate government leaders who push for evidence-based policies and demonstrate a scientific outlook are needed more than glib panderers with attitude.
