With the economy going to pot, it’s not surprising that the presidential candidates haven’t devoted much time to issues of science—R&D funding, education, stem cells, oceans, etc.

Thankfully, that hasn’t stopped reporters from poking and prodding as much as possible. The most recent example of that initiative is the journal Nature’s attempt, published Wednesday, to get the candidates to answer a series of submitted questions on climate and energy. It is a commendable effort, but, unfortunately, at this point it seems that journalists are just reprinting the candidates’ same answers, unable to obtain new insights into their positions.

That isn’t necessarily reporters’ fault—after all, only Barack Obama bothered to respond to Nature; John McCain failed to reply—and it certainly doesn’t mean that the distinguished journal should not have published the information it had. Given the candidates’ reluctance to broach scientific topics on the campaign trail, it doesn’t hurt for publications to rehash existing material, whether or not they are able to contribute fresh information. Nonetheless, if a news outlet is going to bother submitting a list of questions to the candidates this late in the game, it should try to phrase its questions so that they stand the greatest chance of provoking a novel response. Take, for example, the following questions submitted by Nature:

• What methods would you support to reduce domestic greenhouse gas emissions? Are you in favour of a carbon tax, a cap-and-trade system, or some combination of the two?

• How much would you be willing to invest in developing and deploying alternative and renewable energy technologies?

• Where does nuclear power fit in with your vision for the US energy plan? And how do you plan to tackle the problem of nuclear waste?

Come on. Both Obama and McCain have reiterated their basic plans for cap-and-trade, renewable energy, and nuclear many times over, and this information is available at scores of news pages, in addition to the candidates’ own Web sites. These issues beg for more detailed exploration. Nature could have rephrased its questions to read something like this:

• We know your basic outline for cap-and-trade, but do you favor inclusion of any one of the so-called “safety valve” measures that would put a ceiling on the price of carbon? Or better yet, if cap-and-trade fails, do you support using the Clean Air Act and the Environmental Protection Agency to regulate carbon emissions instead?

• We know, broadly, how much you plan to spend (and not spend) on renewable energy, but there is a classic chicken-and-egg problem between producers and suppliers, which exists in both the transportation and utilities industries. The former want the latter to invest in storage and transmission capacity before they invest in research and development; the latter want the opposite. At the federal level, how do you plan to help break that impasse?

• We know your general feelings about the potential for nuclear’s role in our energy economy, and your plans for and concerns about waste. But financing has plagued nuclear development just as much as worries about security and disposal. In fact, it is likely that nuclear would need even more government support than technologies like wind and solar. How far would you go, as president, to help make nuclear financially viable?

Who knows? Politicians are, if nothing else, artful dodgers, and they might have ducked these questions as well. Indeed, one of Nature’s better queries— “Would you support a ban on new coal-fired power plants that do not incorporate carbon capture and storage,” which was a good twist on the more standard “What role do you see coal playing in America’s energy future”—failed to provoke an interesting response. What is certain, however, is that most of the questions, as Nature phrased them, were guaranteed to produce the same canned responses readers have seen before.

Another thing that surely thwarted a better response is that the journal posed the exact same queries to both candidates, which seems absolutely ridiculous. Henceforth, questions must be tailored to the individual candidates, taking into consideration their previous statements and different positions.
