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.

Struggling to live life as an owl

Once again, I'm up late writing (it's almost midnight), but that is a natural thing for me to do, given that I don't actually become wide-awake until about 5 PM. That's the way it's been for me for as long as I can remember. Back in college, my grades started going up once I gave up on those 7:40 AM classes, and tilted my day toward the late morning through mid-afternoon. Quite often, I will get to work at about 10, working until seven or eight at night. This allows me to harness more of my peak time to do the challenging job I do (I am a consumer attorney). Several times a month, I find myself at the office writing a legal brief at one in the morning, working quite effectively. It's not that I don't like to sleep. I love to sleep. It's just that I love to sleep in. That's when it feels natural to me. I know that it's not merely a matter of biology. I stay up late because I want to get one more thing done, and then one more thing. I hate to give up the day, even when it turns into the next day. for me, there's no better time for concentrating than the night. For whatevercombination of nature and nurture, the night is my favorite time. I am an owl. Those other kinds of people, those "larks," often look at owls with suspicion, however. Even when owls spend as much time at work as larks, the larks assume that we owls are goofing off in the morning while they are working hard. What about those evening hours while we owls are still hard at work while the larks are long gone? Larks think that this is our own damned fault and the owls should be getting up earlier. I do think this is part of the Larkian thought process. This perceived tension has often provoked me to think about why it is that my schedule is tilted toward the afternoon and evening. Do I choose for it to be this way or am I biologically geared to be an owl? And why is it that so many owls (me included) end up marrying larks?

The importance of play for adults

In a recent talk at TED, psychiatrist Stuart Brown talked about the vital importance of play. Brown opened his talk by showing an incredible series of photographs demonstrating that a huge hungry polar bear can be seduced into playing with dogs rather than eating them. Like a polar bear, play induces an "altered state" in humans. Play is a great leveler: great differences in power can be overridden by play. In fact, the absence of play is dangerous, as demonstrated by the case histories of mass murderers. Brown describes various kinds of play, including body play (e.g., jumping), object play (manipulating objects), social play, rough-and-tumble play, ritual play and imaginative play (storytelling). These activities simply make us feel better. They are purposeless. In fact, if the purpose is more important than the act of doing these things, they are not "play." As I listened to this list, I was wondering whether sexual play is of the same importance as the other types of play. The study of play is still in its infancy. Historically, this has not been a well-funded area of scientific investigation. Nonetheless, the evidence we already have suggests that play is important for developing cognitively, emotionally and developmentally. We already know that "nothing lights up the brain like play." In fact, the ability to trust is learned through vocal, facial and gestural play signals. As Brown indicates, humans are perhaps the most neotonous species, suggesting a special need for humans to engage in play, whether they are infants or adults. Various animal studies have shown that preventing an animal from playing causes dysfunction. Thus, it seems that play is important for survival. In fact, life without play seems to lead inexorably to depression. When we look back in our history to determine what sorts of activities energized us when we were youngsters, we might deal with see that we have strayed from those things that gave us the pleasure of play. When we explore our personal history, we might find that we are mismatched in terms of career or other activities. [caption id="attachment_5702" align="alignright" width="150" caption="Image by mildegard at dreamstime.com"]Image by mildegard at dreamstime.com[/caption] Brown encourages the audience that they should not set aside time to play. Rather, they (including adults) should infuse every moment of their lives with play. He argues that play is just important for humans as is asleep and dreaming.

Why do many people believe that Barack Obama is not a Christian?

Our minds are big bags of tricks, many of them helpful out in the wild, but prone to deceive us in the modern world. Princeton Psychologist Samuel Wang points out that two of our mind's heuristics, "source amnesia" and "bias dissimulation" (confirmation bias) account for the persistent belief of many people that Barack Obama is not a Christian, in the absence of any evidence supporting this claim.
