The Creation Museum & Ark Encounter

By Mike Reid
August 23, 2016

A peculiar institution exists in the town of Petersburg, Kentucky. It is a natural history museum of sorts, but no ordinary one. Most natural history museums base their exhibits on the principles of modern science. This one is different. This is the Creation Museum. This strange museum does not promote modern science; it challenges it. It bases its exhibits not on science, but on the tenets of young Earth creationism, the doctrine that the Bible is the revealed word of God and that any understanding of how the world and its inhabitants came to be must begin there. Young Earth creationists reject all latter day theories about the world that are inconsistent with this doctrine. They conclude from literal readings of the Old Testament that the Earth is only about six thousand years old and that God created humans and all other types of living things separately, at about the same time, and in largely their present forms. As such, they reject some of the most fundamental principles of modern science, such as Darwinian evolution and the immense age of the Earth. To most modern people, these are the quaint and long outdated myths of a premodern people living in a pre-scientific era. To young Earth creationists, this is how everything began. For anyone searching for validation of such beliefs, the Creation Museum is the place to go.

Near the town of Williamstown, Kentucky, rising like a mountain from the landscape, is a huge wooden "ship." It is no ordinary ship. Resting upon a concrete platform, it lies far from any ocean and was never intended to touch the water. It is not really a ship, but rather the centerpiece of a bizarre theme park called "The Ark Encounter." There, young Earth creationists will find another of their core beliefs brought to life—the story of Noah's flood. According to the Old Testament, disgusted by the depravities of man, God destroyed most of the world that He had originally created with a globally inundating flood. Young Earth creationist scholars date the flood from biblical chronologies as having occurred around 2348 BCE. In this cataclysm, God spared but one righteous family and a representative two of every living animal and plant with the mission that they repopulate the world anew once the flood waters receded. The Ark Encounter theme park is based on this story. At its center is a full-sized "replica" of Noah's Ark with a museum of sorts inside that provides depictions of what its builders think life inside the Ark must have been like and arguments for the story's historicity. Like its sister institution, the Creation Museum, the Ark Encounter presents a biblical, young Earth view of the world. It endeavors to convince visitors that this ancient story is history, not just myth.

The Creation Museum and the recently opened Ark Encounter are the sibling creations of the Kentucky-based Christian apologist organization Answers in Genesis (AiG) and its charismatic president, the Australian-born evangelical and young Earth creationist, Ken Ham. AiG promotes Christian apologetics in a way that I find both intriguing and infuriating. As a one-time geologist, former science teacher, student of Darwinian evolution, and secular activist, I reject the whole notion of creationism. To me, it is an affront to reason. It may be tempting to dismiss young Earth creationists as just a gaggle of uneducated backwoods yokels who cannot bring themselves into the twenty-first century, but that would be a serious mistake. Amazingly, they include elected officials, educators, captains of industry, and many other educated people. In spite of its anachronistic absurdity, creationism is thriving in America in several flavors and is working its way into our educational system and into public policy. Secularists and others who support modern science and the separation of church and state must actively oppose it. To effectively do so, one must understand it. The Creation Museum and Ark Encounter form a "Mecca" of sorts for the young Earth flavor of creationism in America. These are things that I felt I needed to see in order to understand the contemporary creationist movement. So, accompanied by my teenage son Jason, I drove to Kentucky and visited both on a hot Saturday in August of 2016.

We started in the morning with the Creation Museum. As we drove into the parking lot, we both felt a little nervous. It was that unease you feel when you enter a place where you think you don't belong. I wondered if there would be a reaction should anyone notice the Darwin Fish emblem on the back of my car. Fortunately, there was none. Pushing our initial trepidations aside, we bought tickets and went on in.

Mastodon in the main lobby of the Creation Museum
The Creation Museum is an interesting place. My first impression was that of a peculiar blend of natural history museum and off-beat theme park. The place has a sort-of Jurassic Park-type feel to it. There was even a smiling employee standing amidst the crowd gently holding a live and quite large lizard. This instantly reminded me of a scene from the movie Jurassic World. We saw a model pterosaur hanging from the ceiling. Going in further, we encountered a mounted mastodon skeleton and animatronic dinosaurs swaying their long necks and tails in tropically foliaged dioramas. The first clear indication that we were not in a normal natural history museum came when we noticed that one of the dioramas depicts a biblically-attired person sitting next to dinosaurs. This would be the first of several. Like any science-literate person, I know that the last non-avian dinosaurs died out tens of millions of years before the first human appeared. This exhibit should not have startled me given where we were and I was expecting such nonsense, but this scene was just so wrong that it caused me to do a reflexive double-take.

Humans and dinosaurs together in the Creation Museum
The museum was very crowded when we were there and many of the hallways are narrow; so as not to inconsiderately hold up the people behind us, we did not linger long in one place. The museum has a very good fossil collection. It has everything from Paleozoic invertebrates to fishes and dinosaur bones, which are all nicely displayed. Walking by them, I again felt like I was in a normal and well-furnished natural history museum admiring a paleontology exhibit—that was until I stopped to read the accompanying signs. The signs accurately describe what the exhibits are, but go very awry when they give the ages of the fossils. In all cases, they claim that these creatures lived only a few thousands of years ago. They are in fact, far older. Jason and I read the signs, then looked at each other and rolled our eyes. He snickered. I winced in disgust. I looked around to see how other people were reacting. If any of them shared our scorn for the scientific inaccuracies, they did not outwardly show it. I overheard no questioning comments or derisive remarks. From what I could see, nearly everyone else in the crowd was buying into it. I was disappointed by this, but not surprised.

Proceeding into a room with an exhibit called "The Fossil Hunt," we saw a diorama of two life-like mannequins of "scientists" excavating a nearly complete dinosaur skeleton. The walls of the room are covered with simulated rock embossed with impressions of fossils. The "fossils" are of a wide variety of creatures, including many that do not belong together, such as trilobites and dinosaur claws. Trilobites and dinosaurs were not around at the same time in Earth's history, so their fossils are never found together in nature. This is not a problem for the Creation Museum, whose curators claim that God created all life at about the same time and then wiped most of it out less than two thousand years later with a great flood. There I learned that most fossils resulted from masses of mud deposited during Noah's flood. Um, right … There are aesthetically appealing signs with statements from supposed "scientists" sporting impressive-sounding credentials who claim that there is solid evidence for a young Earth and a global flood. The exhibit tries to persuade its visitors that "creation science" is a respectable school of scientific thought that has the support of numerous credentialed scientists and that these "scientists" have concluded, from meticulous study of evidence, that the biblical creation story is largely true. I looked at all this and sighed. This is false, but I have no doubt that if one were to look far and wide enough, one could find a few people with scientific credentials who make such claims. They are a tiny minority and are completely outside of the scientific and academic mainstreams, but visitors are not told this. Like every field, the scientific community has a few crackpots loitering in its midst too.

I was particularly interested in assessing how effective each exhibit was. By "effective," I mean likely to appeal to someone who is not already a biblical literalist. I think that the least effective arguments in the museum are those presented in the many exhibits where they contrast what they call "Man's Word" with "God's Word." In these they spell out what they claim is the secular scientific consensus on some point and then challenge it with excerpts from Scripture. Those arguments will only work with someone who already accepts the Bible literally and therefore needs no further convincing. A non-literalist, even a religious one, is more likely to read them as "Modern Science" vs "Ancient Myth" and will be unimpressed. I think this argument falls flat and I am rather surprised that they use it so much.

In my opinion the most effective, but also the most infuriating exhibit in the museum is one that features the famous "Lucy" skeleton. "Lucy" is the nickname given to a partially complete fossil skeleton of the ancestral hominin, Australopithecus afarensis found in Ethiopia in 1974. Lucy’s skull is very ape-like and small-brained, but her body is much more human-like. The overwhelming consensus among specialists is that A. afarensis was a relative of ours that lived between 3 and 4 million years ago. Multiple lines of peer-reviewed evidence indicate that her kind walked upright. Scientists are uncertain if this species was a direct ancestor of ours or an evolutionary cousin, but we are almost certainly descended from one of the australopiths; so in either case, this species represents an intermediate form that connects us with earlier non-human apes. AiG rejects this idea, of course. Their exhibit contains a laid out replica of the Lucy skeleton. It also contains a well-crafted, full reconstruction of what they claim Lucy probably looked like in life. Unsurprisingly, their reconstruction is quite different from ones displayed in other natural history museums. Theirs portrays her hunched over walking on her knuckles like any scruffy old ape and with a body and face resembling those of a small gorilla. Illuminated panels overlay the reconstruction and light up to delineate the pelvic and limb bones inside. The accompanying signage claims that the skeleton is so incomplete that there are various valid ways to interpret it. According to them, mainstream science is presenting just one way and a biased one at that. The exhibit is correct in its claim that most of her face is missing. It offers several different ways that the sparse facial bones could be reconstructed. They favor an interpretation that looks like a gorilla. However, the exhibit leaves out the essential fact that although Lucy was the first of her kind to be discovered, she was not the last. Since her discovery, other fossils of her kind with more skull material have been found. With the addition of these, scientists now have a pretty good idea of what her kind looked like and it was not like a gorilla. In its exhibit, AiG concludes that Lucy represents an extinct type of ape that was not related to humans. Their conclusion disregards the rigorous study of these fossils done by real scientists from all over the world over many years. These long and meticulous studies of Lucy and the other A. afarensis fossils have led to the mainstream scientific conclusion that she was an upright-walking human relative and not just some unrelated, knuckle-dragging ape. The Creation Museum exhibit is flat out wrong in its insinuation that the mainstream scientific consensus is just someone's subjective interpretation. It is much more than that.

AiG's Lucy walking on her knuckles like a gorilla in the Creation Museum
Far afield as it is, the reason that I think that the Lucy display is the museum's most effective exhibit is that unlike most of the others, it is not  premised primarily on the Bible or divine magic. It has the usual "Man's World" vs "God's Word" sign, but does not rely on that alone to make its case. It presents a faithful replica of the fossil skeleton, a professionally rendered life reconstruction, and some glitzy illuminations of its osteal anatomy. It correctly points out that most of the face is missing and therefore open to interpretation. Superficially, this thesis could seem plausible. Only a specialist would recognize the display’s subtle, but critical misinterpretations of Lucy's limbs, hip, and joints and the exhibit makes no mention of the other A. afarensis fossils that provide further evidence for a more human-like interpretation. With its polish and seemingly sound reasoning, I can certainly understand how a reasonable and intelligent layperson who does not have much scientific background could view this exhibit and be persuaded that Lucy was just another extinct ape with no connection to us.

Lucy as imagined by AiG showing how they claim her limbs articulated
One of the less flashy, but most important parts of the museum is its "Natural Selection is Not Evolution" exhibit where AiG "explains" Darwinian evolution and natural selection. To my surprise, they at first give essentially accurate short descriptions of both concepts, but then make two serious errors. The first of these is that they artificially constrain the power of natural selection. They accept that natural selection can produce changes, but limit it to producing variations only within a "kind" of organism. According to them, only God can produce fundamentally new types of organisms and He did that only once during his week-long creation spree six thousand years ago. They describe a "kind" of organism as being approximately equivalent to a taxonomic family. As an example, they claim that the different kinds of "dogs" we know today, such as wolves, coyotes, foxes, jackals, and domestic dogs are all the varied descendants of the two ancestral canids that Noah took along on his Ark. They allow that natural selection produced these various kinds of "dog" from an antediluvian base form, but stop there and do not accept that a doggish sort of creature could have derived from an earlier non-dog creature, even over the course of many generations. In other words, a dog may have remote descendants that are markedly different from itself, but they will still be dogs. I suppose that this modest concession to evolutionary change allows them, without undermining their base doctrine, to acknowledge the undeniable reality of natural selection, which has been observed in action with insects, microbes, and other short-lived and rapidly reproducing organisms. This also provides a nifty solution to the obvious problem of fitting two of every kind of creature on a boat, no matter how large. According to AiG, there were only a few thousand base "kinds" of creatures prior to the flood, few enough to fit on the Ark. The millions of species around today are all the product of natural selection acting, within family limits, on their descendants. AiG’s version of biology wrongly severs the essential connection between natural selection and organic evolution at large by greatly underestimating the power of cumulative selection over immense periods of time. The second critical problem with this exhibit is that it ignores the many intermediate forms of creatures found in the fossil record as well as genetic commonalities that connect the distinct "kinds" of creatures found today.

The concept of “Deep Time,” which states that the Earth is billions of years old, is fundamental to modern geology and evolutionary biology. It is antithetic to young Earth creationism. For their arguments to stand, AiG must attack this concept head on and they do. Repeated throughout their museum in various ways is a premise that is essential to their whole thesis, that the Earth is only thousands of years old and that the techniques used by secular scientists to date fossils and stratigraphic layers, such as radiometric methods, are not reliable. They make multiple attacks on the integrity of these methods. AiG claims that there is no empirical way of knowing how old these things really are and that they can only be understood within a biblical chronology. They appear to fully understand that if fossils can be definitively shown to be of great and vastly differing ages, their whole 7-days of divine creation thesis collapses.

"Man's Word" vs "God's Word" in the Creation Museum
The Creation Museum is well done. Its exhibits are attractive and thoughtfully laid out. It has most of the things that one would expect to find in a mid-sized natural history museum, even a planetarium. The museum tries to be scientific much of the time; however, it is premised on the a priori assertion that the Bible is inherently true. An assertion made without evidence is not science. Many of the museum’s arguments against mainstream scientific principles are based on their inconsistency with the Bible or the presumed young age of the Earth. The fundamental theme of this museum is like a large, intricate house of cards; it is an impressive and thoughtfully erected structure, but if you remove the base card, the whole thing comes crashing down. The presumption of biblical inerrancy is the Creation Museum’s base card.

Adam and Eve in the Creation Museum
With its Creation Museum, AiG makes a believable show of its fundamentalist casuistry by blending some real science with a heavy dose of nonsense to produce a murky pseudoscientific goulash from which most of the lay public cannot tell where one ends and the other begins. It supports its anti-intellectual concoction with an impressive collection of genuine fossils and other specimens of nature. These it elegantly displays to the visitor tainted with small, but essential misinterpretations. Visitors who already accept the Bible literally will likely leave the place confident that science confirms their religious beliefs. Those who are religious, but unsure about creationism will be intrigued, perhaps persuaded. Visitors who do not accept biblical literalism and who have some scientific literacy will dismiss the whole museum as a bastion of nonsense. A core mission of the Creation Museum is to convince the public that “creation science” is real science. I have no doubt that with many of its visitors, it succeeds in this.

Animatronic dinosaur exhibit in the Creation Museum
After about three hours in the Creation Museum, Jason and I decided that we had had enough of the place. As we walked back to our car, our brains felt rotted. In my mind, I was processing a dizzying melange of feelings ranging from bemusement to bewilderment to disgust. I must admit that I was also impressed with how professional looking the place is. It was time to head off to our next stop.

It took us about 40 minutes to drive from the Creation Museum to the Ark Encounter. Upon arrival, one has to park in a large lot that is some distance away from the central attraction. There one pays a fee to board a shuttle bus into the park. AiG’s Ark is enormous. It dominates the local landscape. They claim that it is the largest timber-framed structure in the world and I can believe it. Jason and I walked over to it. We walked around it and under it, just taking it in. We then got in line to go "aboard." I had heard that on opening day the month before, attendance at the Ark Encounter had been sparse. This was certainly not the case when we were there. The park was packed. We had to stand in a zig-zagging line beneath the structure for more than half an hour before we got in. Upon entering its hull, we were again struck by its size. Inside its cavernous interior are thousands of wooden cages of varying sizes, many with models of animals peering out of them. Moving further in, one encounters dioramas depicting scenes from the biblical story along the hull. The inside is climate controlled and offered us a welcome sanctuary from the sultry summer heat outside. It is interesting, aesthetically attractive, and redolent of freshly cut wood. I thought to myself that this would be a great place to hold a wine tasting or a craft show. It just has that look about it.

The Ark Encounter
The Ark Encounter is basically a huge, three-dimensional, interactive story book that retells the Old Testament fable of the Great Flood and Noah's Ark. And honestly, the thing is pretty cool. This is by far the most serious and sophisticated rendering of the story that I have ever seen. Most depictions of this story are cartoonish and simply ignore its plenitude of logical problems, such as how Noah could possibly fit two of the millions of species of animals that exist on any vessel—even one this big. A modern aircraft carrier would not hold them all. They simply do not explain how he could have fed them and disposed of their waste or how he could have kept the carnivores from consuming the other animals. The practical problems with this story go on and on. AiG attempts to explain away the most obvious of these. As I mentioned earlier, they claim that all existing animals are descendant of a few thousand base kinds that Noah was able to fit on his Ark. They even borrow the idea of natural selection from modern biology as the mechanism that produced the postdiluvian diversity that we see today. However, like those in the Creation Museum, the Ark exhibits adhere to their claim that natural selection can only produce variations within a base kind of animal created by God. They cherry-pick those bits of modern science that they can shoehorn into their narrative and disregard the inconvenient rest.

One of the decks inside the Ark
How did Noah prevent the carnivores from eating the other animals? God made them vegetarians while on the Ark. What about the really big animals, like elephants? How did Noah fit them in? Easy, God only sent the smaller individuals among them, such as juveniles, to the Ark. Did you know that there were dinosaurs on Noah's Ark? AiG cheerfully acknowledges the irrefutable evidence for the past existence of dinosaurs and the Bible says that two of every kind of animal were taken aboard. Since the Bible is always right and dinosaurs clearly once existed, there must have been dinosaurs on Noah's Ark. AiG's Ark has cages with dinosaurs in them. Did Noah somehow fit gigantic sauropods onto the Ark too? Remember, all animals are descended from just a few base kinds. AiG estimates that only about fifty or so kinds of dinosaurs would have been needed to later produce their known diversity and they were smaller back then. Sure, their ancestors would have fit on the Ark. AiG acknowledges that dinosaurs and many other types of animals are now extinct, but their forebears must have all been there on the Ark with Noah. They went extinct later and only within the past few thousand years. Do you find it curious that there is no mention of these spectacularly large and hence rather conspicuous animals in the Bible or in any other ancient source? AiG has an answer for that too. Postdiluvian dinosaurs may have been the source of later legends about dragons and other giant monsters.

Dinosaurs on Noah's Ark
My son and I left the Ark after a few hours with much the same feelings we had after leaving the Creation Museum—a mix of admiration for its scale and sophistication and disconcertion with its absurdity. As spectacular as AiG's Ark is, I think it less effective than the Creation Museum. I cannot imagine that anyone other than an adamant religious fundamentalist would accept its story unquestioningly. The logical problems with the story of Noah's Ark are so intractable that even a person of deep faith, but who holds onto at least a thread of rationalism, would have trouble accepting it literally. Still, AiG has done a better job than anyone before in bringing this fable to form. I must credit them for creativity in their attempts to address the story's many failings, but even their most thoughtful explanations inevitably fall short.

The cavernous interior of the Ark
The Creation Museum and the Ark Encounter are impressive. Never before have I seen modern science attacked so professionally and with such panache and flair. No where else have I seen pseudoscience and logical absurdities packaged and persuasively delivered with such glittering polish and on such a colossal scale. What AiG does, it does well. In spite of my disgust with their deep scientific and historical flaws, I rather enjoyed both attractions in a perverse sort of way and I must grudgingly acknowledge a measure of admiration for Ken Ham. I almost want to meet him. This is similar to the way I felt a few years ago after visiting the Thomas Road megachurch and Liberty University in Lynchburg, Virginia. Both are the mammoth creations of the late Rev. Jerry Falwell, Sr. and his "Moral Majority." I was awed by the sizes of those institutions. It is remarkable what one truly dedicated and talented person starting with almost nothing was able to achieve in one life-time. Even though I detest everything that Falwell stood for, I could not help but admire the man for his energy and organizational skills. This is how I feel about Ken Ham also. He is clearly a tremendously talented man who possesses profound organizational skills, but like Falwell before him, I wish that he would be apply his abilities to better purpose.

E.O. Wilson and The New Enlightenment: A Call to Understanding

by Gary Berg-Cross

Biologist Edward O. Wilson’s new book is called ‘The Social Conquest of Earth.’  It’s largely provides a biological perspective on 3 grand philo-cultural questions (famous questions, inscribed by Paul Gauguin in his giant Tahitian painting of 1897):


    ·     “Where do we come from?
  •      What are we?
  •      Where are we going?” 

 Unlike traditional philosophy or religion Wilson wants to incrementally advance on these from scientific understanding and theory.  He speaks in terms of the relatively rare, eusocial nature of humans and how this might have develop as part of pre-adaption. (Eu-Social means the highest level of organization of animal sociality, and is defined by 3 characteristics: cooperative brood care (including brood care of offspring from other individuals), overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups).
 While it takes a while to make a scientific case Wilson argues for this approach as better than what we are handed by religion approaches.  It’s of no real help at all  he argues aside from making us feel like we know:
          “mythmaking could never discover the origin and meaning of humanity”
Contemporary philosophy  also comes up with a backhand irrelevant, having as Wilson argues
 “long ago abandoned the foundational questions about human existence.”
Well maybe and maybe at Harvard, but there are relevant, contemporary folks in philosophy I think.

I largely agree that the most likely approach to answering the 2 above foundational questions is to follow the scientific method as applied by the proper and emerging disciplines.   So we have Biology, Psychology, Anthropology, Archaeology and Sociology along with newer disciplines like neuroscience, epigenetics and evolutionary biology.  It’s a wonderful matrix of expanding understanding and especially nice when a master of one or two of these spends the time to synthesize a view understandable to non-experts.  Others in this senior synthesis of ideas worth reading and listening to are Jared Diamond whose last 3 or 4 books are enlightened warning that touches on our eroding environment in an historical context. They are wake up calls such as we have heard too from Richard Dawkins, of course, whose latest book An Appetite for Wonder: The Making of a Scientist  is autobiographical.

Wilson draws on all these sources to explore the development of human society and some objective self-awareness needed to understand our collective selves. The path has bounced from ancient art, primitive religion, the founding of philosophy, and finally an integrated science perspective. As a Biologist Wilson sees a tipping point in these various views of human nature and such with Charles Darwin's 19th century theory of evolution by natural selection. Together with other sciences this theory can be applied to understand human behavior and deal with some age old controversies.
Wilson outlines the broad human story and fills in some details to illustrate our new understanding.  Wilson does this, for example, spinning a more complex story than a simple genetic basis for shared individual- and group-level selection factors.  Both selfish and group favoring factors exist. As a result there is intense inter-group competition along with unstable group composition that results in:
 "an unavoidable and perpetual war ... between honor, virtue, and duty ... and           selfishness, cowardice, and hypocrisy..." 
A payoff is the later section of the book called “A New Enlightenment.” In a sequence of chapters he covers the topics of language (pre-adapted cognition evolved into the ability to create abstractions, and later to use arbitrary symbols for communication, thus leading to the evolution of language)., culture, morality ("The naturalistic understanding of morality does not lead to absolute precepts and sure judgments, but instead warns against basing them blindly on religious and ideological dogmas," p. 252)., religion and art. These provide a much different and nuanced view to approach an answer to the earlier question - “What are we?”,
His warning about the tribal aspects of religion are a meme that one hopes is widely heard. Organized religion, Wilson argues, is a simple expression of an evolution favored tribalism. So the "illogic" of religious belief is not a weakness in traditional human cultures, since it serves a social role of binding a group's members together to the exclusion of outsiders.  You may get to be part of a group by abandoning your differences and converting to the group’s core beliefs. In pre-scientific days creation- genesis stories & myths employed by the early Big religions are all explainable as cultural relics. Wilson does a back hand refutation of "phantasmagoric elements" as the result of hallucinogenic drugs.  This natural explanation, he argues, is a much more plausible as the basis for things like John's “visions” recorded in the Book of Revelation than the idea that god intervention actually happened. The same goes for nomads wandering in the desert.
“.. you can see this especially in the difficulty of harmonizing different religions. We ought to recognize that religious strife is not the consequence of differences among people. It's about conflicts between creation stories. We have bizarre creation myths and each is characterized by assuring believers that theirs is the correct story, and that therefore they are superior in every sense to people who belong to other religions. This feeds into our tribalistic tendencies to form groups, occupy territories and react fiercely to any intrusion or threat to ourselves, our tribe and our special creation story. Such intense instincts could arise in evolution only by group selection—tribe competing against tribe. For me, the peculiar qualities of faith are a logical outcome of this level of biological organization.
Yes, it is a good explanation and a warning too.

Misinformation, Lies and Ignorance



By Gary Berg-Cross

At a recent meeting I attended the topic of American decline came up somewhat as an obvious assertion as fact with the subsequent search for why this was happening.  After the usual suspects of ineffective government and various stresses such the wealth gap and declining resources it was suggested that an additional reason was “ignorance.” This was elaborated a bit as people not understanding they are being fooled, lied to and manipulated.  For a number of reasons people are just misinformed. We can blame Fox unNews and others parts of conservative media for misinformation on the Affordable Care Act - see What Epic Propaganda Looks Like Obamacare And Permanent Right-Wing Misinformation which includes the sensational rumor mongering ideas of “death panels” and fact-free claims that:

These are the type of unbalanced, sensational, emotion-generating stories that abuse common sense but appeal to some bias and thus spawns meme waves.  The more boring reality of a neutral story can't compete. 

How do we handle this? One idea is to simply ask, "what is the source or these claims?"  Challenging the source is one way to fight misinformation (MI) in a person, but it may not stem a tide of MIs.  Media and political machines provide an easy way to spread these oversimplified memes which are not sourced back to facts, but are just myths.


 As Mark Twain wrote:
It ain't what you don't know that gets you into trouble.
 It's what you know for sure that just ain't so.

Yes, and Psychology tells us a bit about why people hold on this this Foxian misinformation. You can read a bit about it in Misinformation and Its Correction: Continued Influence and Successful Debiasing by Australian Stephan Lewandowsky and others.  


Novelty, emotional capability and over simplicity making misinformation memetic is part of it.  Having a megaphone to get the meme out is another, but it is also important that we live an nonintellectual climate that
accepts a naive idea of binary balance or what I called binary thinking.  You see in arguments about evolution vs. creationism.  There are 2 sides and so it is balanced to give them equal discussion.  No, this is not the way to balance fact and opinion, although Fox news seems to place the asymmetry in the other direction – more opinion than facts.  People will believe something if it comes from a well-positioned source.  Should I believe in creationism?  Well if it is good enough for my moral leaders (Rabbis, priests, ministers etc.) than it is good enough for me.

 The internet and the social web makes this easier than ever to get a preponderance of opinion and advocacy out there as opposed to literal fact. And of course people believe internet misinformation because it sounds literal like an authoritative source.

 
“A survey of the first 50 Web sites matching the search term “weight loss diets” revealed that only 3 delivered sound dietary advice.” Why People Believe Weird Things and 8 Ways to Change Their Minds by Jeremy Dean


I once had a conversation with a person who thought the facts were against climate change.  His source was a site with some authoritative  definitive name like Climate Facts I don’t remember the actual name, but I looked it up and found it was funded by Exxon. That gave me something to use aside from different climate change facts. With my confused friend I could show why the site he found might be misinforming him – they had hidden motives.


The lesson here is that people are partly ignorant because it is hard to keep up with the flow of information, and not critical thinking or skeptical enough. But there is also responsibility on the part or the 4th Estate to inform.  As Carl Bernstein noted:


The lowest form of popular culture - lack of information, misinformation, disinformation and a contempt for the truth or the reality of most people's lives - has overrun real journalism. 


Psychologist Jeremy Dean proposes a few other ways to unstick folks from misinformation.  These include keeping the rebuttal short and sweet. By sweet one means not attacking the person and being affirmative and not just negative. Don’t overload a misinformed person but dose things out as they may be able to assimilate it and do it in an exchange
An interesting idea which I haven’t tried systematically is to, as Dean calls it “affirm identity.” The idea is to mitigate people’s natural resistance to new, countering, unpleasant facts by getting them to affirm their identity. So if people think of themselves as generous or open or having Christian values they may be better able to accept the value of funding food for hungry people while thinking of those identities. Research suggests this helps people deal with inconsistencies between their beliefs and the new information that is conflicting with it.


In this informative process there are some things to avoid.  After you have noted a topic you are addressing, don’t keep repeating a myth associated with it, such as “death panels”. It just activates emotions, so re-frame the discussion and repeat your main points, which should include facts to give

them a chance to replace unfacts. Think of it as dismantling a structure in stages, but providing a new, sturdy structure to replace it.  I had that experience in that same meeting where we discussed ignorance.  One person supported the idea that our society was declining because it was, yes, too complex, but that this was driven by the government making things too complex in order to be “fair.”  Step by step people in the group offered simple examples of how things like the tax code or laws are complex due to greed and interest on the part of power groups able to influence the construction of tax exemptions etc.  By the end we had a group understanding and the myth of government imposition of fairness was dismantled.

Lewandowsky and colleagues conclude their article with a mixed note of caution and information consumer advice:
“Correcting misinformation is cognitively indistinguishable from misinforming people to replace their preexisting correct beliefs. It follows that it is important for the general public to have a basic understanding of misinformation effects… Widespread awareness of the fact that people may “throw mud” because they know it will “stick”…will contribute to a well-informed populace.”

 Yes, we are all information consumers and know how to move other’s opinions.  It is the task of ethical information agents to pursue the true and educate our fellow citizens.

Teaching Evolution and Climate Change

by Gary Berg-Cross

It is good to note, as the New York Times did, that educators unveiled new guidelines (called the Next Generation Science Standards) recently and called for:

" sweeping changes in the way science is taught in the United States  including, for the first time, a recommendation that climate change be taught as early as middle school. "

This notable with 26 states and several national scientific organizations (including National Research Council, the National Science Teachers Association, the American Association for the Advancement of Science) cooperating, even if as has been noted the climate change recommendation is a bit buried in the report:

"Human activities, such as the release of greenhouse gases from burning fossil fuels, are major factors in the current rise in Earth’s mean surface temperature (global warming),”

And  as the New York Times story points out, some conservative and religious groups are challenging that inclusion, along with the teaching of evolution, which they will also be required to learn about. Lack of adequate coverage is a problem in the US curriculum. As noted by Mother Nature News in the link above "A perceived conflict between science and religion has led Americans to rank nearly last among industrialized countries in understanding evolution, educators told a major science conference this weekend."

The new guidelines comes also in response to the growing controversy over public education driven by  the influence of religious conservatives sitting on State and local Ed boards in part. Empirical evidence make evolution is a validated & predictive scientific theory for the web of life we see. It is foundational for understanding biological science, yet some conservatives insist that it is just a hypothesis and other hypotheses like intelligent design also be taught in public schools ( perhaps with other theistic ideas about creation). 

We'll see what the backlash and blockage to the new science standard will be. I can imagine it will be a bit like the reactionary efforts in some swing states as I noted in my blog on the state's as bizarre engines of reactionary policies.
A group called Citizens for Objective Public Education stated that the new curriculum would “take away the right of parents to direct the religious education of their children.” Its that rights vs. what Science-tells-us-is-true-and-I-don't-want-to-hear head-in-the-sand argument.

It's already getting noted in some states like (What's the matter with?) Kansas which in 1999 made the national news when the state board adopted a science standard that deleted references to evolution from the state guidelines.  Sort of a State's rights thing that descended to the individual school district level where  the decision to teach evolution would be made.  Makes you wonder is districts will now succeed from States to protect their religious "rights". Since 99, the Kansas state board has revised the standards at least three times based on the swing in liberal vs. conservative balance of power among the 10-member State board.

As  Robert A Heinlein said:

It is a truism that almost any sect, cult, or religion will legislate its creeds into law if it acquires the political power to do so, and will follow it by suppressing opposition, subverting all education to seize early the minds of the young, and by killing, locking up, or driving underground all heretics.

Dan Dennett's Latest Cognitive Toolbox


by Gary Berg-Cross

Daniel Dennett's new book "Intuition Pumps and Other Tools for Thinking", should be out in a few weeks but it already has some reviews. The book is about methods can we use to answer life's most fundamental questions. You can actually preview some of the chapters which stat by dealing with
General Thinking Tools - like Occam's razor, but also Occam's Broom. This is followed by discussing Tools for Meaning, tools for thinking about evolution, consciousness and the like.  These include "imagination extenders and focus-holders" that Dennett and others have developed for dealing with difficult topics that some of us like to read about and discuss: evolution, meaning, mind, and free will. In other words topics that cross and integrate great philosophical, psychological and biological ground.

As always Dennett offers insight and ideas that are debatable. A big topic here is a continuation of Dawkins' discussion of memes and how they obey some abstracted tenets of Darwinian Evolutions.


His starting argument asking if words are things, symbolic but thingy.  This going to provoke some commentary.

 If you grant that words are" things" then we offer the possibility of consider memes some kinds of "things" also perhaps in a realm between physical things and symbolic thing. Well how about calling it a conceptual thing?

Discussing Science Left and Right

 
There is a something on a competing book called, "Science Left Behind: Feel-Good Fallacies and the Rise of the Anti-Scientific Left“ that is being promoted by more conservative circles.  One  recommendation comes from Michael Medved, nationally syndicated talk radio host, author of The 10 Big Lies about America...He's not my favorite source of ideas and  while Medved finds it " Entertaining, enlightening, and important" (along with the American Enterprise Instituted)  I believe  other review such as Publisher's weekly that summarize it as follows:
 
While frequently illuminating, Berezow and Campbell employ sweeping generalizations (e.g., "[I]n truth, Europe is a nice place. European countries have good food.") that often undermine convincing arguments. And their list of 12 issues that would require a blend of science and politics is underwhelming—among them: "Managing resources efficiently" and "Addressing global poverty." (Sept.)
 
Of course the people who really like to use the book are anti-evolutionists such as the http://www.evolutionnews.org/2012/10/science_left_b065791.html site which hawks the book in arn article:
 
"Science Left Behind Can Teach Us about Political Tactics of Intelligent Design Critics"
 
You might also add climate change critics using the book to blur issues too.  Below is a longer review by Ken Silber of the book and comparing it to Mooney's book that was discussed at the December meeting.
 

 


Review: Science Left Behind


I opened with some eagerness my review copy of Science Left Behind: Feel-Good Fallacies and the Rise of the Anti-Scientific Left, by Alex B. Berezow and Hank Campbell. Having spent much time in recent years criticizing conservatives for denial and ignorance of scientific facts, and being a center-right type myself, I am interested in similar failings on the left. But this is a badly disappointing book.
Some time ago, at David Frum’s blog, I criticized Chris Mooney’s The Republican Brain for (in my view) overstating its case that science is revealing a broad tendency among conservatives to deny or distort facts. Let me say now that Mooney’s book is a model of fair-mindedness compared to Science Left Behind.

Berezow and Campbell open by setting up their target: "progressives." They quickly unleash a bombardment of stereotypes:
Who  are the people we’re calling progressives? Generally, they’re the kind of people who think that overpriced granola from Whole Foods is healthier and tastier. They’re the people who buy “Terra Pass” bumper stickers to offset their cars’ carbon emissions. And they’re the sort of people whose beliefs allow them to feel morally superior to everybody else who disagrees—even if scientists are among those doing the disagreeing.

The authors distinguish between “progressives” and “liberals” on the grounds that the former evince a social authoritarianism not shared by the latter. I find this rather notional, given the virtual interchangeability with which the terms are widely used. Supposedly, though, whereas liberals favor economic interventionism but “value social liberty,” progressives
seek dominion over issues such as the environment, food production, and education. They endorse bans on plastic grocery bags, McDonald’s Happy Meal toys, and home schooling. They hold opinions that are not based on physical reality about how energy and development should work. And, most significant, they claim that all of their beliefs are based on science—even when they aren’t.

So it seems that progressives are antithetical to science as a matter of definition. Oddly, this comes just a few pages after the authors assure us that “the purpose of this book is not to demonize all progressives. We just want to demonize the loony ones.” And: “Though some progressives are pro-science, many within their ranks are not.”


Then there’s a look back to what progressive once meant, but the authors are no better on their history. Consider this:
For a time, progressivism made for good politics. [Theodore] Roosevelt was joined under the banner of “progressives” by Democrats including Woodrow Wilson and William Jennings Bryant [sic]. All of these men aimed to mobilize rationalism and science to promote “progress,” just as their philosophy’s name suggested.

Bryan is better described as a populist than a progressive, and the notion that he “aimed to mobilize rationalism and science” would’ve been news to H.L. Mencken during the Scopes Monkey Trial.


This just scratches the surface of what’s wrong with this book. The authors present various examples of  leftists being out of step with science. Some of these are issues that cut across ideological boundaries (anti-vaccine hysteria, for instance). Some are issues where the left-wing anti-science types have had little success in getting the policies they want or even getting support from Democratic politicians (genetically modified foods). Some are just marginal and obscure issues to begin with (the use of compostable utensils in the Capitol Hill cafeteria).

Berezow and Campbell are right that there are anti-science attitudes on the left. They are wrong to see these as of similar current significance to anti-science views on the right.  They fail to show any issue that is a progressive counterpart to the conservative stance of recent years on climate change—that is to say, an important issue where one side, including its elite, is not only grossly out of step with the scientific community but has succeeded in getting its anti-science views reflected in public policy.

After filling the book with tendentious and trivial point-scoring, the authors close with a chapter on the science-related issues that "really matter." This is filled with banality such as “it is imperative that Americans have a serious debate about the country’s future in space.” Thanks for the tip.
