Over at Slate, Daniel Sarewitz cites a 2009 Pew Research poll that found only 6 percent of scientists are Republicans, while 55 percent are Democrats. According to Sarewitz, this poses a problem because several controversial scientific issues — such as global warming and embryonic stem cell research — are intrinsically tied to partisan policy positions.
But while Sarewitz looks into the potential political dilemmas of this trend, he doesn’t spend as much time focusing on the really interesting question: why are so few scientists Republicans?
Left-wing bloggers have come up with the predictably unconvincing responses (i.e., there are no Republicans in science because Republicans hate facts), but there may be a much more simple explanation buried in the original polling report. According to Pew, the survey’s sample of scientists was extracted entirely from the membership rolls at the American Association for the Advancement of Science:
Results for the scientist survey are based on 2,533 online interviews conducted from May 1 to June 14, 2009 with members of the American Association for the Advancement of Science (AAAS), under the direction of Princeton Survey Research Associates International. A sample of 9,998 members was drawn from the AAAS membership list excluding those who were not based in the United States or whose membership type identified them as primary or secondary-level educators.
And the society didn’t just provide Pew with its membership list. “[AAAS Director] Waylon Butler and his colleagues as AAAS were instrumental at constructing the sample of scientists and managing the recruitments of participants for the scientist survey,” says the Pew report.
This is important, because the AAAS is (as its name suggests) a political advocacy group. And, according to its website, the top issues it advocates for are climate change legislation, increased funding for the National Science Foundation, stem cell research, and green energy initiatives. Obviously, these aren’t the types of efforts that Republicans tend to support. It’s not hard to see why GOPers wouldn’t want to shell out the $146 membership fee to join an organization whose main mission is to advocate for issues they personally oppose.
So it makes sense that the Pew poll may be skewed in favor of liberal Democrats. But the question of where most scientists stand on the political spectrum is still worth looking into, and I’m curious to see what a broader study might show.




More Good News from the MTF
Today at the White House President Bush announced the results of this year’s Monitoring the Future (MTF) survey. This widely respected survey, conducted by the University of Michigan’s Institute for Social Research, tracks smoking, drinking, and illicit drug use among the nation’s secondary school students, assessing every year about 50,000 8th, 10th, and 12th graders in more than 400 secondary schools.
The key findings are that 8th, 10th, and 12th graders across the country are continuing to show a gradual decline in the proportions reporting use of illicit drugs.
“The cumulative declines since recent peak levels of drug involvement in the mid-1990′s are quite substantial, especially among the youngest students,” said University of Michigan Distinguished Research Scientist Lloyd Johnston, the principal investigator of the MTF study.
The proportion of 8th graders reporting use of an illicit drug at least once in the 12 months prior to the survey was 24 percent in 1996 but has fallen to 13 percent by 2007, a drop of nearly half. The decline has been less among 10th graders, from 39 percent to 28 percent between 1997 and 2007, and least among 12th graders, a decline from the recent peak of 42 percent in 1997 to 36 percent this year. All three grades showed some continuing decline this year in the prevalence of illicit drug use, though only the one-year decline in 8th grade (a drop of 1.6 percentage points) achieved statistical significance. The rates for the three grades now stand at 13 percent, 28 percent, and 36 percent. Today 860,000 fewer young people than in 2001 are using drugs.
