My growing impatience with creationists: a side by side comparison of evolutionary biology and creationism

Over the past three years of writing for DI, I have discussed evolution with many creationists who have posted comments at this site. These exchanges have been good for me. They have forced me to think harder about exactly what it is that I understand about evolution and what evidence supports my understanding. These exchanges have also helped me to understand the concerns and mental gymnastics of creationists. I now find myself getting increasingly impatient with the creationists, however. It was initially interesting to banter with creationists because I enjoyed the challenge of trying to understand why they claimed the things they claimed. I’m now getting annoyed with these creationists arguments, and it mostly has to do with the refusal of creationists to acknowledge relevant scientific observations from the real world. My frustration also stems from the anti-scientific mindset of creationists. As a group, creationists refuse to argue even-handedly. They become skeptical only when it suits their immediate needs—they don’t apply skepticism equally both to their own claims and to the claims of those with whom they disagree. As a group, they scurry to find disingenuous arguments to support points that they actually learned in churches, not in science books. Many of them are consciously dishonest, and when you call attention to their obvious untruths, they try to change the subject. There are exceptions to this rule. There are some creationists who aren’t consciously being dishonest, but those creationists tend to be so incredibly ignorant of the principles of the scientific theory of evolution that they lack the ability to meaningfully criticize evolution. Their arguments are aimed at things that no competent scientist has ever claimed. For numerous excellent examples of this problem, see these videos by AronRa here and here. It is well-established that humans are susceptible to committing errors caused by the confirmation bias. We seek out evidence that supports our current beliefs. Scientists are imminently aware of this danger and they work hard to design experiments to counteract this bias. Creationists (who don’t even try to run experiments) excel at feeding their confirmation biases. They proudly exclude evidence that threatens their opinions. Creationists come to mind when I consider David Hume’s quote: “Reason is and ought only to be the slave of the passions, and can never pretend to any other office than to serve and obey them.” [A Treatise of Human Nature, (2nd Ed.), Book II, Part I, Section III (“Of the influencing motives of the will”) (1739)].

Why is there a fire hydrant in the middle of Forest Park?

Why is this fire hydrant in the middle of Forest Park, in St. Louis, Missouri? Is it there for the firefighters in case an ant hill catches fire? A flower? If I used the logic employed by Creationists, I might simply say that God put that fire hydrant there. To the extent that anyone accepts such an explanation, there would be no need for further inquiry (nor any real possibility for further inquiry). To the extent that someone accepts the "explanation" that "God did it," he or she would miss out on a rich factual history, teaming with direct evidence upon which one can build an incredibly strong circumstantial case. One really can explain the presence of this hydrant, even without direct evidence (presumably, no one who saw this hydrant being installed is still alive). I'm working on a post regarding creationism (including its modern version, "intelligent design"). Yesterday's walk in the park reminded me that circumstantial evidence can be strong, indeed. In fact, circumstantial evidence can make for airtight cases. Circumstantial evidence can even be much stronger than authority (because authorities--e.g., the park police--are often wrong). Therefore, people who really want to know don't simply throw up their hands and declare that the hydrant is there "Because God put it there" even when a person in a position of authority tells them this story. hydrant-up-close1An inspection of this hydrant shows that it was manufactured in 1887 (or is that number 1881?). It was thus installed sometime after 1881. Why would it be installed in the middle of a park? Perhaps it wasn't just a park back then. Perhaps it was installed because that land was to be the location of a huge construction project: the 1904 World's Fair held in St. Louis. Perhaps, after the Fair was over, this hydrant was not removed. Perhaps there are some photos of the Fair that would include this little fire hydrant, a vestigial reminder that something much more elaborate once occupied this place. All of these questions can be answered if one takes the time to examine real evidence that is currently available. If one looked further for evidence, one would find tons of corroboration, including a huge "Flight Cage" that now houses a bird exhibit at the St. Louis Zoo, also an original part of the 1904 World's Fair. Of course, one could also find numerous books filled with photos, names, dates and interviews. Notice that I'm referring to corroborative written materials--many sources that overlap--not simply reading one book over and over until one is more and more convinced. Creationists are happy to employ these open-minded investigative methods almost always, in almost every aspect of their lives. This method of asking questions and then following the evidence wherever it leads is actually an extension of common sense. It's a shame that when it comes to one particular incredibly important aspect of their lives, determining what kind of beings we are, creationists refuse to use this direct extension of common sense.

A program that gets college students enthusiastic about the scientific theory of evolution

David Sloan Wilson has written some terrific articles on the topic of evolution. I recently ran across a 2005 article he wrote for PLoS Biology www.plosbiology.org titled "Evolution for Everyone: How to Increase Acceptance of, Interest in, and Knowledge about Evolution." The article explains the method by which Binghamton University has successfully infused its undergraduate curriculum with real-life applications of evolutionary theory. The EvoS program began in 2002. Here's the mission of EvoS:

The mission of EvoS is to advance the study of evolution in all its manifestations, including all aspects of humanity in addition to the biological sciences. Many organizations and websites promote the study of evolution, but EvoS is unique in two respects.

• EvoS is based on the realization that evolutionary theory will probably never be generally accepted--no matter how well supported by facts--unless its consequences for human affairs are fully addressed. Once evolution is seen as unthreatening, explanatory, and useful for solving life's problems, then it becomes not just acceptable but irresistable to the average person (see the tutorial for more).

• EvoS makes a connection between evolutionary theory and the unification of knowledge, which has always been the goal of a liberal arts education and contemporary efforts to integrate across disciplines. The same kind of unification that took place in the biological sciences during the 20th century is now taking places for the human behavioral sciences and humanities--but is not yet reflected in the structure of higher education. EvoS is the first program to diagnose this problem and comprehensively provide a solution at a campus-wide scale.

David Sloan Wilson explains that the Binghamton program makes use of 50 faculty members representing 15 departments. The program was created based on the following assumption: "Evolution can be made acceptable, interesting, and powerfully relevant to just about anyone in the space of a single semester."

Orchids are back at the Missouri Botanical Garden

Once again the orchids are on display at the Missouri Botanical Garden. I snapped some photos or these incredible beings. After all, they are our cousins. Richard Dawkins estimates that animals diverged from the plant kingdom about two billion years ago. orchid1 I've written previously about Darwin's fascination with orchids here. For today, I will simply paste in a few new photos of these incredibly beautiful plants. I've posted many more of my photos of today's show at one of my public web albums at Picasa.
