Acceptance of evolution in Canada.

There seems to be some confusion regarding the level of acceptance of evolution in Canada based on the Angus Reid poll in June 2007. In particular, several people have made the claim that the level of acceptance of this unifying principle of biology is roughly the same in Canada as in the United States. Although the results of the AR poll are disappointing, they do not indicate an equivalence of views between the two nations.

Here are two relevant press releases from Angus Reid:

U.S. Majority Picks Creationism over Evolution (April 25, 2006)

Most Canadians Pick Evolution Over Creationism (June 19, 2007)

It is true that the recent poll suggests that nationally, a disappointingly low majority of 59% of Canadians accept the notion of common descent. However, only 22% accept young earth creationism. In Ontario, the data are especially disheartening, with only 51% of respondents accepting evolution (but still only half as many choosing creationism). In Quebec, 71% accept evolution and only 9% align with creationist ideas. The original report can be accessed here.

The US poll referred to above (by CBS) indicates that 53% of respondents believe that life was created in its current form within the past 10,000 years by God, 23% accept a form of evolution guided by God, and 17% believe in a strictly natural evolutionary account. The questions in the Canadian poll were not broken down in this way, but this poll still indicates that only 40% of Americans accept any form of evolution and 53% believe in a young earth. Other polls give similar results (see Miller et al. 2006, Science 313: 765-766). There is, unsurprisingly, a strong relationship between religiosity, political affiliation, and opinion about evolutionary science.

A more recently conducted Gallup poll gave slightly more promising results than the earlier CBS finding, with 43% choosing young earth creationism, 38% ascribing to theistic evolution, and 14% accepting unguided evolution. This would put the total who accept some form of evolution at 52%, and when asked directly about evolution, 53% of respondents considered it to be either “definitely true” (18%) or “probably true” (35%). However, this encouraging result must be weighed against the fact that when asked directly about young earth creationism, 66% said it was either “definitely true” (39%) or “probably true” (27%). As Gallup put it,

It might seem contradictory to believe that humans were created in their present form at one time within the past 10,000 years and at the same time believe that humans developed over millions of years from less advanced forms of life. But, based on an analysis of the two side-by-side questions asked this month about evolution and creationism, it appears that a substantial number of Americans hold these conflicting views.

Clearly, Canada does not rank at the level of nations like Iceland, Denmark, Sweden, France, or Japan where public acceptance of evolution is very high (up to 80%), but neither do they fall in the same category as the United States. In particular, what we do not see in Canada, at least based on this single survey, is a high level of acceptance of creationism. Nevertheless, there is much work to do in educating the public in Canada. Most notably, an alarming percentage (42%) believe that humans and dinosaurs coexisted despite a majority accepting evolution. In other words, they are right about evolution but rather confused about the details of life’s history. In some ways, this is not surprising, given the countless portrayals of “cavemen” and dinosaurs together in cartoons, movies, and other venues. I would not be surprised if a majority of people also believe that penguins and polar bears cohabitate while accepting the fact of a round Earth with two poles.

On framing.

I finally checked out the “framing” presentation by Chris Mooney and Matthew Nisbet which is available with PowerPoint slides here. I am not particularly interested in the debate over this issue, but I thought I would give it a try in light of my hope of improving media coverage and public comprehension of science. This is not my entry into the debate as I think it has garnered more attention that it warrants already; this is simply a set of thoughts on the issue after having spent the time watching the talk.

I will say that I found much to agree with as far as the descriptive components were concerned. That is, I think Mooney and Nisbet make some good arguments with regard to what is and is not working in scientific communication. This is Nisbet’s subject of research, and it was useful to see actual data applied to the question. My sense was that “framing” likely is something that nonspecialists do use when evaluating complex issues, and that this is a problem for scientists who want to convey complicated ideas with societal ramifications to them. However, I think the discussion runs aground in three major areas: 1) How it is presented to scientists, 2) In the failure to distinguish it from “spin” or “marketing”, and 3) When it shifts from description to prescription.

As to the first, Mooney and Nisbet seem to use an only partially appropriate “framing” when speaking to scientists who, both as individual people and as part of a collective, exhibit inherent preferences, biases, and other filters. To wit, scientists in general will be unwilling to compromise certain principles, and there appears to be insufficient appreciation of this fact by framing advocates. For example, scientists will not simplify to the point of eroding accuracy, they will not do anything that could be perceived as lying to the public, and they will never give up on the notion that getting the public to understand science is the primary long-term goal. From what I can gather, Mooney and Nisbet are not asking scientists to compromise on these principles, but this is not stated clearly — following their own advice, this should be presented clearly and repeatedly so as to reassure scientists that they are not being told to betray their scientific ideals. (And if they are asking scientists to do so, then this should be made clear also so that the debate can be put to a swift end).

The question of motives also comes into play as part of the mis-framing of framing. No one can be totally objective, so what scientists are trained to do is to look for biases and associated violations of objectivity so that these can be factored into the evaluation of scientific arguments. Personally, I found myself asking “why do they care what scientists do?”. One obvious explanation is that they are concerned citizens with a particular interest in science and its impacts on society. This is not stated upfront, however, and so questions come up about whether this isn’t an exercise in attention getting (and possibly book promoting) as much as a sincere call to action.

Finally, while I do not read their blogs, I have seen a few links to statements that I have found offensive to my scientific sensibilities. As a case in point, Mooney argues on his blog that science journalists are not the problem (this is also stated in the presentation). It would seem to follow, therefore, that if science is reported inaccurately, sensationalized, overstated in its implications, or otherwise distorted, that is the fault of scientists. Worse, Mooney goes so far as to argue that scientists should just shrug it off and move on if they are misquoted in the media. Again, this ignores the frame that scientists use, in which accuracy is of paramount significance. He also seems to think that simply telling scientists about the difference between a science journalist (well-trained and comprehensive) and a non-science journalist reporting on science (no expertise or experience in dealing with such issues) will make the resentment of the media’s handling of research disappear. It will not.

The second point is the one that has been the primary subject of discussion by some prominent scientist-bloggers, namely that “framing” bears a striking resemblance to “spin”. We all know that “spin” plays a substantial role in politics. To scientists, this is not something to be emulated. I won’t go so far as to say that framing is mere spin, but throughout the presentation I had the strong notion that it was largely indistinguishable from “marketing”. Scientists should care about how their work is presented to and received by the public, and therefore marketing is a legitimate consideration. Indeed, scientists market their work often — to granting agencies, students, journals, and colleagues. Adding some audience-specific adjustments when dealing with the public is perfectly reasonable, but if that’s all “framing” is, then it’s really just repackaged marketing truisms.

The third point, in which Mooney and Nisbet transition from describing the issue to prescribing what scientists should do, was by far the weakest part of the talk. In fact, I found almost nothing in their presentation that actually applied to me as an individual researcher. Almost everything they suggested actually fell under the purview of science writers, press offices, lobby groups, professional societies, or educational organizations. I still do not know what they expect me to do even with information in mind about how the public frames important topics. As a result, much of the talk seems to be about telling scientists what they are doing wrong with no real solutions that individual scientists can or will implement.

If I may, I would also add that Mooney and Nisbet’s discussion is, at heart, not about science or communication, but about American politics. In many other countries, scientific literacy is much higher, issues do occupy the primary stage in election campaigns, and religion and partisanship play a much smaller role in influencing decisions about science. Once again, this suggests that education about science early on is an effective strategy and a viable objective. The question of framing is more geographically and temporally localized than this, and so it is difficult for some scientists who are trained to look beyond such limitations to the larger picture to make framing a primary tool.

In stark contrast to all of this ambiguity and apparent misreading of scientific audiences, I point to the recent book A Scientist’s Guide to Talking with the Media by journalists Richard Hayes and Daniel Grossman, published by the Union of Concerned Scientists. I am only part way through the book, but already I can note that it does a fine job of framing the topic in a manner acceptable to scientists. Hayes and Grossman are very clear that they have the utmost respect for science and scientists, and that they absolutely do not wish to see spin implemented at the expense of accuracy. Theirs is a well articulated set of practical suggestions for dealing with the media. They do not appear to blame scientists but instead point to examples where different strategies could have forestalled problems. They do not let science reporters off the hook, but do try to promote a better understanding among scientists of the challenges of writing for a nonspecialist audience. They do not point out the challenge and leave the solutions unclear, but give point by point suggestions on how to improve the important relationship between scientists and those who report science. As a scientist with some experience with the media, I find a great deal of use in this volume. And I do not hesitate to recommend it as an alternative to the far less helpful argument about framing.


Professors who blog.

Technology & Learning has a recent story about “Professors who blog“. They make the point that many profs who blog view it as part of their “service” component in the form of outreach*. Their research is instead published in peer-reviewed journals, books, conference proceedings, and other traditional media. As readers know, this is also how I see the role of blogs by scientists. Blogs are no substitute for peer reviewed publications, but they are a useful medium in which to discuss science from various perspectives and to make the information more accessible to non-scientists around the globe. I suspect that, in time, more scientists will come to see the value of blogs as an outreach apparatus and will make time for them despite being chronically overcommitted.

* Most science faculty have three components to their jobs. Research, teaching, and service, often distributed at 40 : 40 : 20 (though this varies). Students sometimes are unaware that teaching a given class may represent only 10-20% of a professor’s job description (though it invariably takes up much more time than this, especially if he or she strives to be an effective educator). Something to consider next time you feel the prof isn’t giving you enough personal attention or doesn’t respond to your emails fast enough. 🙂


Introducing two new journals in evolution.

Two new journals are set to launch in 2008 that deal with the teaching and application of evolution. The first, to be published by Springer, is Evolution: Education and Outreach. The editors are Niles Eldredge and his son Greg. I am privileged to be serving on the editorial board along with some very important people in the evolutionary research, education, and outreach communities. The official launch of the journal will occur at the National Association of Biology Teachers annual meeting in November. The second, to be published by Blackwell, is Evolutionary Applications. It is edited by my colleague Louis Bernatchez of Université Laval in Québec.

Here are the publishers’ journal descriptions:

Evolution: Education and Outreach

Darwin’s Theory of Evolution revolutionized scientific thinking. Since the publication of The Origin of Species 147 years ago, this theory has been extensively and rigorously tested. Overwhelming scientific evidence from many disciplines exists to support this theory. From the vast body of scientific evidence that has accumulated, we have come to an understanding of all areas of the biological world – from our cells and DNA to our lakes and forests. Evolutionary principles are the foundation of all modern biology and have led to major advances in fields as diverse as molecular biology, developmental biology, genetics, behavior, and paleontology. As such, evolutionary theory is a fundamental and necessary component of modern science education.

Evolution: Education and Outreach will promote accurate understanding and comprehensive teaching of evolutionary theory for a wide audience. Targeting K-16 students, teachers and scientists alike, the journal will publish articles to aid members of these communities in the teaching of evolutionary theory.

Evolutionary Applications

Evolutionary Applications publishes papers that utilize concepts from evolutionary biology to address biological questions of health, social and economic relevance. Papers are expected to employ evolutionary concepts or methods to make contributions to areas such as (but not limited to): agriculture, aquaculture, biomedicine, biotechnology, conservation biology, disease biology, fisheries and wildlife management and invasion biology. Theoretical, empirical, synthesis or perspective papers are welcome.


Chimps are not more evolved than humans or anyone else.

I like New Scientist. I even did a short interview with them about a cool genomics story (“How chemicals can speed up evolution“, 6 May 2006, p.16). But this headline from their news service really annoys me: Chimps ‘more evolved’ than humans.

The short news article starts out with “It is time to stop thinking we are the pinnacle of evolutionary success…”, which of course is true except that it was time to stop thinking this 150 years ago, and then continues with “… chimpanzees are the more highly evolved species, according to new research”.

What they mean is that, based on the recent study, it appears that the rate of fixation by selection of mutations apparently has been higher in the lineage that has led to chimpanzees than in the lineage that has led to humans since they split from a common ancestor several million years ago. Which lineage experienced the changes can now be inferred by comparison with the macaque genome, which is less closely related to chimps and humans than the latter two are to each other; without such an external comparison, one can not say which lineage had changed, only that one or both of them had. Most likely, this boils down to differences in long-term historical population sizes in the two lineages (selection is stronger in large populations, genetic drift in small populations).

Couching this interesting finding in terms of who is “more evolved” than whom is not helpful, even with the scare quotes. As someone who teaches evolution at the upper-year undergraduate level, I can tell you that students come into the class with a lot of preconceptions about evolution, one of them being the notion that some extant species can be ranked as “more evolved” than others. It is subtle misinformation like this, compounded over many years, that makes my job harder by the time they arrive in my course.

Please, please, PLEASE stop appealing to common misconceptions about evolution in news stories, even if the headline will catch the attention of (previously misinformed) readers.
