The Limits of Reason

The antipathy with which fundamentalists hold science and reason is difficult to understand. The emotional backlash, more storm than counter argument, often surprises. A simple statement can bring about the most strident denunciations, the pitch and timbre of the debate oscillating out of proportion to the content being discussed. Or so it seems. In the course of debating the truth, validity, utility, or relevance of certain topics, the nondogmatic must come to a point of fatigue by the seeming impossibility of finding common ground. At which time the debate either fizzles, the rationalist yields out of frustration, or the fundamentalist (of whatever stripe, on whatever topic) is ignored and bypassed. This last leads to a situation wherein the argument festers like an infection. It does not go away, often to the dismay of those watching and certainly to those who thought it without merit. You can flip this on its head and make the same claim in the other direction. At least, up to a point.

Consider the following statements:
  • (1) I am not descended from a monkey.
  • (2) God gave us dominion over the earth.
  • (3) Homosexuality is an abomination.
  • (4) The earth is only 6000 years old.
  • (5) The Bible is the inerrant word of God.
What is the one common, salient feature of each one of these statements? They are each one unqualified and utterly emotional statements. They are statements made in reference to personal belief, without reference to any external corroborative evidence or comparative context. They are, with the single exception of the Earth’s age, unanswerable in any reasonable way. Taken one at a time, therefore: (1) Of course you aren’t. It’s obvious. You’re descended from earlier generations of homo sapiens sapiens.

Fundies really do say the darndest things

It's enough to make Jesus depressed. I just learned of a site called Fundies Say the Darndest Things. This is your one-stop shop for finding "an archive of the most hilarious, bizarre, ignorant, bigoted, and terrifying quotes from fundies all over the internet." The bad science is reason enough to visit the site, at least until you are sufficiently depressed at hearing such nonsense. It's pretty amazing stuff. Consider, too, the 100 all-time most ignorant and offensive fundamentalist quotes. Each on of them is taken from a fundie website and includes the link to the original (consider Rapture Ready, for example). Consider watching FSTDT's reenactment of some of the quotes at youtube (warning: some coarse language). All of this will leave you shaking your head wondering how people can be so pompously ignorant.

Charles Darwin’s exceedingly dangerous idea

In Darwin's dangerous Idea: Evolution and the Meanings of Life, Daniel Dennett describes Darwin's idea as the "best idea anyone has ever had."

In a single stroke, the idea of evolution by natural selection unifies the realm of life, meaning, and purpose with the realm of space and time, cause and effect, mechanism and a physical law. But it is not just a wonderful scientific idea. It is a dangerous idea.

What exactly was Darwin's dangerous idea? According to Dennett, it was "not the idea of evolution, but the idea of evolution by natural selection, an idea he himself could never formulate with sufficient rigor and detail to prove, though he presented a brilliant case for it." (42) Dennett considers Darwin's idea to be "dangerous" because it has so many fruitful applications in so many fields above and beyond biology. When Dennett was a schoolboy, he and some of his friends imagined that there was such a thing as "universal acid,"

a liquid "so corrosive that it will eat through anything! The problem is: what do you keep it in? It dissolves glass bottles and stainless steel canisters as readily as paper bags. What would happen if you somehow came upon or created a dollop of universal acid? With the whole planet eventually be destroyed? What would it leave in its wake? After everything had been transformed by its encounter with universal acid, what would the world look like? Little did I realize that in a few years I would encounter an idea-Darwin's idea-bearing an unmistakable likeness to universal acid: eats through just about every traditional concept, and leaves in its wake a revolutionized world-view, with most of the old landmarks are still recognizable, but transformed in fundamental ways.

(63) Darwin's idea is powerful, indeed. Many people see it as having the power to ruin the meaning of life.

People fear that once this universal acid has passed through the monuments we cherish, they will cease to exist, dissolved in an unrecognizable and unlovable puddle of scientific destruction.

Dennett characterizes this fear is unwarranted:

We might learn some surprising or even shocking things about these treasures, but unless our valuing these things was based all long on confusion or mistaken identity, how could increase understanding of them diminish their value in our eyes? (82)

How undependable are the experts?

We are in the middle of a huge economic crisis. Should we listen to the experts? Of course we should, because the economy and the financial sector are horrifically complicated. What happens when the experts disagree, however? To which experts should we listen? I took a stab at that question recently, but I remain unconvinced that any of the economics experts can be trusted. Yes, there are people like George Soros who have made a phenomenal amount of money during the crisis, but this makes me wonder whether he (and all of the other recent success stories) are smart or whether they are lucky. Today, Nicholas Kristof (in the NYT) reminds us that many experts (at least political experts) have a terrible track record. His opening sentence: "Ever wonder how financial experts could lead the world over the economic cliff?" He warns us of the “Dr. Fox effect,” named for a "pioneering series of psychology experiments in which an actor was paid to give a meaningless presentation to professional educators." Despite the fact that the lectures consisted of gibberish, they were well received. He mentions a study showing that "clinical psychologists did no better than their secretaries in their diagnoses." He also mentions a study by Philip Tetlock which determined that "The [82,000] predictions of [284] experts were, on average, only a tiny bit better than random guesses — the equivalent of a chimpanzee throwing darts at a board." Those experts who were the most impressive to most people "provided strong, coherent points of view, who saw things in blacks and whites." I'm reminded of Alan Sokal's intentionally nonsensical article that he submitted to the postmodern journal, Social Text. See here for more of the details. BTW, if you want to generate your own postmodern bullshit, use this postmodernist bullshit generator (every time you hit the link, more impressive-sounding bullshit will be assembled automatically into an article). How far astray are we led by "experts"? Consider investment "experts." There are none worse. Entire industries are built on the thoroughly disproved notion that a stock-picker can consistently beat the market. Dan Smolin has made a career of proving that stock-picker experts are thoroughly and demonstrably terrible at what they claim to be. But many of us still run to these financial "experts" to help us pick the "right" stocks. Just think of the hundreds of political military experts who were similarly awful at their recommendations and predictions regarding the invasion of Iraq. They appeared hundreds of time on network TV during the few weeks prior to the invasion, all of them confident in their assessments and advice. Consider, also that fewer than 1% of them took anti-war stances. Consider, also, that many of these "experts" were secretly in positions to financially benefit from an invasion of Iraq. Consider the thousands of religious experts, from coast to coast, who loudly and confidently tell their religious followers that there is a heaven and that they will go there, without the tiniest big of evidence in support. The followers of fundamentalist preachers continue to listen to these guys even when they attack evolutionary biologists, even though these religious leaders have no training in science and no basic understanding of the principles of evolutionary biology. Everyone loves weather forecasters, right? These guys are wrong so incredibly often that no station dares to post their track records for those five-day forecasts they confidently present night after night. The list goes on and on. We insist on listening to the experts, medical experts, beauty experts, psychologists, their track records be damned. That's because they are the best that we've got, no matter how wrong they are how often. The bottom line is that we crave experts because we crave certainty, even where there isn't any. The confirmation bias causes us to rely heavily on experts hawking our own opinions, even when there is no evidence in support, as long as the expert dishes out those opinions with a loud confident voice. And a fancy business suit doesn't hurt either.

As If We Didn’t Know

Politics dictated FDA policy? Say it isn't so! According to this NY Times piece, the Bush Administration (they get the blame because, after all, he was the Decider) bade the FDA to meddle with contraception when it suited a certain agenda. What I find so delightful about this, as with the Dover PA decision on Intelligent Design in the classroom, is that a Republican judge, this time a Reagan appointee, made the call. The thing is, contraception and all that it implies really ought to be a conservative issue. I mean, really---it has all the hallmarks of the last 60 years of conservative philosophy built on the rights of the individual, the freedom from interference being chief among them. You would think conservatives would have leapt on this a long time ago, staking it out as exemplary of the idea of American Individualism and the freedom to act as a moral agent, dictating one's own destiny and making determinations about how one will live one's life free from government meddling. Handing both men and women the tools---provided by the free market, to boot---to manage their own lives in accordance with their formulation as individuals of the American Dream should have been a slam dunk for conservatives. They should have been cheering for it since the days of Margaret Sanger. What is more, given the attitude of the communist states, which dismissed Sanger and the entire notion of family planning as a bourgeois, capitalist plot to undermine the growth of the collective, this should have been part and parcel of rearing a generation of people cumulatively opposed to Soviet style socialism and collectivism. Everything about the Choice movement smacks of good ol' fashion American Values! It is the perversity of the debate that is ironic, that it should be those who are castigated as liberal soldiers in the march to socialism and its destruction of all things individualist and true blue American who are the champions of the idea that people ought to have full say in the when and if of having children. How did this happen?
