Arguments against Creationism/Intelligent Design

For a lighthearted but spirited refutation of creationist misconceptions of Earth history, call your local library (or check out their catalog on the internet) and see if they have Creation/Evolution Satiricon: Creationism Bashed. It’s written by the well-known marine geologist/geomorphologist Robert S. Dietz and illustrated by John C. Holden. Stephen G. Brush, a historian of science, examines scientific theories for dating the age of the Earth, particularly radiometric dating in Transmuted Past: The Age of the Earth and the Evolutions of the Elements from Lyell to Patterson; Volume 2 in the series, A History of Modern Planetary Physics. Cambridge University Press, 1996. For a shorter but hardly less lucid critique of claims by creationists that the Earth is only a few thousand years old, coupled with an exposition of radiometric dating methods, see Stephen G. Brush, “Finding the Age of the Earth by Physics or by Faith,” Journal of Geological Education, vol. 30, pp. 34-58, 1982.

In a challenging book intended for the lay audience, G. Brent Dalrymple reviews scientific evidence for the age of the Earth, Moon, and Solar system in such well documented and critical manner that it leaves no room for uncertainty or doubt: The Age of the Earth, Stanford, California: Stanford University Press, 1991. The book’s greatest virtue is its detailed analysis of radiometric dating methods. The many, many examples and the exhaustive chronology that are presented reveal how imaginative but sometimes wrong researchers have been in the past. But then he shows how tirelessly other researchers have checked their work, finding the errors and developing more reliable methods. It is also clear that the results of proven techniques have been checked rigorously against the results of other methods, until there can be little scientific doubt about the final conclusions. One cannot read that book with an open mind and continue believing a few warped scientists conspired to conjure up a patently false system and that hundreds of later scientists simply fell into line and confirmed their bizarre fantasies. Philip Kitcher, a philosopher of science at the University of Vermont, has written a marvelously lucid summary of the evidence for evolution and the overwhelming case against its opponents in a thoughtful and witty attack on 'scientific' creationism, Abusing Science: The Case Against Creationism, Cambridge, MA: MIT Press, Updated March 2001; go online and read the excerpt, “Creationist’s Blind Dates” at: http://chem.tufts.edu/science/Geology/KitcherBlindDates.htm. Kitcher, who as a philosopher is concerned with the way science operates, is particularly adept at showing how creationists distort Karl Popper’s views on scientific method and how they misuse such books as Thomas Kuhn’s Structure of Scientific Revolutions.

Of course, readers interested in the geoscience side of the argument over creationism should read Arthur N. Strahler’s marvelously written and well-reasoned, Science and Earth History: The Evolution/Creation Controversy, 2nd ed., Amherst, New York: Prometheus Books, 1999. Strahler was professor of geomorphology in the Department of Geology at Columbia University and author of numerous textbooks in geoscience. His book is a comprehensive treatment of the ongoing conflict between scientists who accept the theory of evolution and creationists. He reviews the philosophy, methods, and sociology of empirical science from astronomy to zoology, contrasting those with the belief systems of religion and pseudoscience. In one very interesting section he establishes sound criteria for distinguishing science from pseudoscience and demonstrates with devastating logic that creation science fails to meet the criteria of scientific enterprise.

A more recent and delightful work based on sound science and leavened with literary grace and elegance is also well worth reading, no matter what your evolutionary point of view, but only if you have an open mind, which by my personal experience is something almost entirely lacking in creationists: Richard Dawkins, The Ancestor’s Tale: A Pilgrimage to the Dawn of Evolution. New York: Houghton Mifflin, 2004. For a very well written and tightly reasoned point of view of a Christian geophysicist, see: Roger C. Wiens, PhD, Radiometric Dating: A Christian Perspective, material originally written in 1994 and revised in 2002: http://www.asa3.org/ASA/resources/Wiens.html.

And don’t forget the early and remarkable essay by the evolutionary biologist and devout Russian Orthodox Christian Theodosius Dobzhansky that criticized Young Earth creationism and espoused what he called evolutionary creationism: “Nothing in Biology Makes Sense Except in the Light of Evolution,” American Biology Teacher, vol. 35 125-129, 1973. Note that that article may have been inspired by the work of Jesuit physical anthropologist and philosopher, Pierre Teilhard de Chardin, whom Dobzhansky much admired.

Everyone interested in the cultural war between the adherents of evolution and creationists (in this camp I squarely place those who believe in intelligent design) should read two recent books. The first, by the physical anthropologist Eugenie C. Scott, is Evolution vs. Creationism, Berkeley, California: University of California Press, 2005. It is both a history of the debate and a collection of essays written by partisans from both sides. Its main attribute is its clear explanation of the scientific method and the astronomical, biological, chemical, and geological bases of evolutionary theory. As good as that book is, even better is Michael Ruse’s The Evolution-Creation Struggle, Cambridge, Massachusetts: Harvard University, 2005. As a philosopher of science, Ruse (self-described as an ardent Darwinian) has testified against the inclusion of creationism in public school science curricula  He cautions all of us on the use of the word “evolution,” especially since it has two meanings: the science of evolution and something he terms evolutionism, which is the part of evolutionary ideas that reaches beyond testable science. In other words, Ruse interprets the struggle between science and theology as a war between two rival metaphysical worlds.

Matt Young (PhD physics-optics) and Paul Strode (PhD biology-ecology) provide a series of clear, concise, and lively discussions for everyday people in their excellent book, Why Evolution Works (and Creationism Fails). New Brunswick, NJ: Rutgers University Press, 2009. Their narrative is a well-written and highly readable response to creationists’ objections to evolution. Their science-based work takes pains to demonstrate that creationists profoundly misunderstand the very nature and structure of science and avow positions that are contradictory and inconsistent.

One positive indication, though no one should put much “faith” in it, is that courts at various levels repeatedly have held that public schools must be religiously neutral and must not advocate religious views. In that vein, in 1987 the Supreme Court ruled that teaching creationism in the public schools was unconstitutional.

And finally, I wonder if it ever occurred to our creation science and Young Earth friends to explain with scientific rigor the fossilized marine sedimentary rocks (from the Ordovician) forming the summit of Mount Everest, known locally as Chomolungma, Goddess Mother of the World, and explain how those marine sediments were pushed and shoved to an elevation of nearly 30,000 feet. For the latest and slickest version of neo-creationism that has many rich, powerful, and right-wing political backers, interested readers should consult published articles that discuss the implications of the late-2005 decision of a federal judge against the Dover (Pennsylvania) School District in what may have been a critical test case that ruled intelligent design and creationism are one and the same and have no place in a biological science curriculum.

Certainly many arguments can be and have been made that demonstrate the fallacy of creationism/young earth/intelligent design (see above). One that I personally hold dear is practical in nature. To believe in creationism etc., etc., one must reject not only biology and geology but also basic principles in astronomy-astrophysics, physics, geophysics, and geochemistry. How people are prepared to do that I simply can not imagine, even when it is explained to me by those who have faith in creationism. It's a puzzle that can only be explained by Julius Caesar's famous dictum: Fere libenter homines id quod volunt credunt. Men willingly believe what they want.

HAPPY 2013 TO ONE AND ALL from SOB

Scientific Articles on Global Warming

“The accompanying pie chart [see below] should be instructive. It was produced by James Lawrence Powell [Ph.D. in Geochemistry from MIT], a former member of the National Science Board under Presidents Ronald Reagan and George H. W. Bush. He did a broad search in scientific journals for every peer-reviewed study of climate change and/or global warming since 1991. He found 13,950 of them, the combined work of 33,690 scientists from around the world. Precisely 24 of the 13,950 studies rejected global warming. That piece represents 17 hundredths of 1 percent of the pie. End of debate.” Source: Editorial: St. Louis Post-Dispatch, 12-27-12.

“The articles have a total of 33,690 individual authors. The 24 rejecting papers have a total of 34 authors, about 1 in 1,000.” Source: http://www.jamespowell.org/  


According to Powell, about one tenth of one percent of scientific authors who published in peer-reviewed journals on global climate change issues in the last twenty years do not believe that that change is caused by humans. One tenth of one percent. But I suppose some people believe that’s not a consensus or that all the other scientists who believe in AGW are intentionally falsifying or skewing their results, or are getting paid by some nefarious liberal organization.

But one tenth of one percent seems incredibly persuasive, given that the top ten countries where the research was performed are, in numerical order: USA, England, China, Germany, Japan, Canada, Australia, France, Spain, and the Netherlands. Persuasive only if you have an open mind.

Again, according to Powell, the results of his study demonstrate the existence of a hoax targeted on misleading the public about global warming. A small group of global warming deniers has created the illusion that scientists disagree about climate change by using a well-funded campaign of smoke and mirrors and every form of communication except peer-reviewed scientific papers. But that campaign hasn't succeeded. Source: James Powell. “The State of Climate Science: A Thorough Review of the Scientific Literature on Global Warming.

It turns out conservatives have been caught wearing the Emperor’s New Clothes with their bare asses hanging out for all to see. Readers who yearn for documentation of the existence of an organized movement on the part of conservatives to obscure the science of global warming are encouraged to examine the following peer-reviewed sources. Please note that this list is far from all inclusive.

Aklin, Michael, and Johannes Urpelainen. 2014. Perceptions of scientific dissent undermine public support for environmental policy. Environmental Science & Policy 28: 173-177. Abstract: This article shows that even modest amounts of scientific dissent reduce public support for environmental policy. A survey experiment with 1000 Americans demonstrates that small skeptical scientific minorities can cast significant doubt among the general public on the existence of an environmental problem and reduce support for addressing it. Public support for environmental policy is maximized when the subjects receive no information about the scientific debate, indicating that the general public's default assumption is a very high degree of scientific consensus. Accordingly, a stronger scientific consensus will not generate public support for environmental policy, unless skeptical voices become almost silent.

Bray, D. 2010. The scientific consensus of climate change revisited. Environmental Science & Policy 13(5): 340-350. Abstract: This paper first reviews previous work undertaken to assess the level of scientific consensus concerning climate change, concluding that studies of scientific consensus concerning climate change have tended to measure different things. Three dimensions of consensus are determined: manifestation, attribution and legitimation. Consensus concerning these dimensions are explored in detail using a time series of data from surveys of climate scientists. In most cases, little difference is discerned between those who have participated in the IPCC process and those who have not. Consensus, however, in both groups does not amount to unanimity. Results also suggest rather than a single group proclaiming the IPCC does not represent consensus, there are now two groups, one claiming the IPCC makes overestimations (a group previously labeled skeptics, deniers, etc.) and a relatively new formation of a group (many of whom have participated in the IPCC process) proclaiming that IPCC tends to underestimate some climate related phenomena.

Cook et al examined 11,944 abstracts from the peer-reviewed scientific literature from 1991–2011 that matched the topics 'global climate change' or 'global warming'. They found that, while 66.4% of them expressed no position on anthropogenic global warming (AGW), of those that did, 97.1% endorsed the consensus position that humans are causing global warming. They also invited authors to rate their own papers and found that, while only 35.5% rated their paper as expressing no position on AGW, 97.2% of the rest endorsed the consensus. In both cases the percentage of endorsements among papers expressing a position was marginally increasing over time. They concluded that the number of papers actually rejecting the consensus on AGW is a vanishingly small proportion of the published research.

Doran, Peter T., and Maggie Kendall Zimmerman. 2009. Examining the scientific consensus on climate change. Eos, Transactions, American Geophysical Union 90(3): 22-23. Abstract: Fifty-two percent of Americans think most climate scientists agree that the Earth has been warming in recent years, and 47% think climate scientists agree (i.e., that there is a scientific consensus) that human activities are a major cause of that warming, according to recent polling (see http://www.pollingreport.com/enviro.htm). However, attempts to quantify the scientific consensus on anthropogenic warming have met with criticism. For instance, Oreskes (2004) reviewed 928 abstracts from peer-reviewed research papers and found that more than 75% either explicitly or implicitly accepted the consensus view that Earth's climate is being affected by human activities. Yet Oreskes’s approach has been criticized for overstating the level of consensus acceptance within the examined abstracts (Peiser 2005) and for not capturing the full diversity of scientific opinion (Pielke 2005). A review of previous attempts at quantifying the consensus and criticisms is provided by Kendall Zimmerman (2008). The objective of our study presented here is to assess the scientific consensus on climate change through an unbiased survey of a large and broad group of Earth scientists.

Flynn, James, Slovic, Paul, & Mertz, C. K. 1994. Gender, Race, and Perception of Environmental Health Risks. Risk Analysis 14(6): 1101-1108. Abstract: This paper reports the results of a national survey in which perceptions of environmental health risks were measured for 1275 white and 214 nonwhite persons. The results showed that white women perceived risks to be much higher than did white men, a result that is consistent with previous studies. However, this gender difference was not true of nonwhite women and men, whose perceptions of risk were quite similar. Most striking was the finding that white males tended to differ from everyone else in their attitudes and perceptions–on average, they perceived risks as much smaller and much more acceptable than did other people. These results suggest that sociopolitical factors such as power, status, alienation, and trust are strong determiners of people's perception and acceptance of risks.

Freudenburg, William R., and Violetta Muselli. 2013. Reexamining climate change debates: Scientific disagreement or scientific certainty argumentation methods (SCAMs)? American Behavioral Scientist 57(6): 777-795. Abstract: Despite strong scientific consensus that global climate disruption is real and due in significant part to human activities, stories in the U.S. mass media often still present the opposite view, characterizing the issue as being “in dispute.” Even today, the U.S. media devote significant attention to small numbers of denialists, who claim that scientific consensus assessments, such as those by the Intergovernmental Panel on Climate Change (IPCC), are “exaggerated” and “political.” Such claims, however, are testable hypotheses—and just the opposite expectation is hypothesized in the small but growing literature on Scientific Certainty Argumentation Methods, or SCAMs. The work on SCAMs suggests that, rather than being a reflection of legitimate scientific disagreement, the intense criticisms of climate science may reflect a predictable pattern that grows out of “the politics of doubt”: If enough doubt can be raised about the relevant scientific findings, regulation can be avoided or delayed for years or even decades. Ironically, though, while such a pattern can lead to a bias in scientific work, the likely bias is expected to be just the opposite of the one usually feared. The underlying reason has to do with the Asymmetry of Scientific Challenge, or ASC—so named because certain theories or findings, such as those indicating the significance of climate disruption, are subjected to systematically greater challenges than are those supporting opposing conclusions. As this article shows, available evidence provides significantly more support for SCAM and ASC perspectives than for the concerns that are commonly expressed in the U.S. mass media. These findings suggest that, if current scientific consensus is in error, it is likely because global climate disruption may be even worse than commonly expected to date.

McCright, Aaron M. and Riley E. Dunlap. 2011. Cool dudes: The denial of climate change among conservative white males in the United States. Global Environmental Change 21(4): 1163-1172. Abstract: We examine whether conservative white males are more likely than are other adults in the U.S. general public to endorse climate change denial. We draw theoretical and analytical guidance from the identity-protective cognition thesis explaining the white male effect and from recent political psychology scholarship documenting the heightened system-justification tendencies of political conservatives. We utilize public opinion data from ten Gallup surveys from 2001 to 2010, focusing specifically on five indicators of climate change denial. We find that conservative white males are significantly more likely than are other Americans to endorse denialist views on all five items, and that these differences are even greater for those conservative white males who self-report understanding global warming very well. Furthermore, the results of our multivariate logistic regression models reveal that the conservative white male effect remains significant when controlling for the direct effects of political ideology, race, and gender as well as the effects of nine control variables. We thus conclude that the unique views of conservative white males contribute significantly to the high level of climate change denial in the United States.

McCright, Aaron M. and Riley E. Dunlap. 2013. Bringing ideology in: the conservative white male effect on worry about environmental problems in the USA. Journal of Risk Research 16(2): 211-226. Abstract: Extending existing scholarship on the white male effect in risk perception, we examine whether conservative white males (CWMs) are less worried about the risks of environmental problems than are other adults in the US general public. We draw theoretical and analytical guidance from the identity-protective cognition thesis explaining the white male effect and from recent political psychology scholarship documenting the heightened system-justification tendencies of political conservatives. We utilize public opinion data from nine Gallup surveys between 2001 and 2010, focusing on both a single-item indicator and a composite measure of worry about environmental problems. We find that CWMs indeed have significantly lower worry about environmental problems than do other Americans. Furthermore, the results of our multivariate regression models reveal that this CWMs effect remains significant when controlling for the direct effects of political ideology, race, and gender and the effects of nine social, demographic, and temporal control variables – as well as the effect of individuals generalized (non-environmental) risk perceptions. We conclude that the white male effect is due largely to CWMs, and that the latter’s low level of concern with environmental risks is likely driven by their social commitment to prevent new environmental regulations and repeal existing ones.
