American belief in evolution is growing: poll


Alien SaintA new Harris poll released this month shows that Americans apparently are losing their belief in miracles and gaining it in science. The recent poll showed that American belief in evolution had risen to 47% from its previous poll level of 42%, in 2005.

True, it’s not an overwhelming increase, and it’s still less than half the population, but it is an improvement. Belief in creationism dropped 3% during that time, to 36%. Good news, of course, but don’t break out the champagne yet. There’s other data and it’s not all so good.

At the same time more Americans are believing in the science of evolution, American belief in many religious teachings is falling. Belief in miracles, heaven and others has dropped since the last poll:

  • 72% believe in miracles, down from 79 percent in 2005;
  • 68% believe in heaven, down from 75%;
  • 68% believe that Jesus is God or the Son of God, down from 72%;
  • 65% believes in the resurrection of Jesus Christ, down from 70%;
  • 64% believe in the survival of the soul after death, down from 69%;
  • 58% believe in the devil and hell, down from 62%;
  • 57% believe in the Virgin birth, down from 60%.

CNS News also tells us the poll shows:

  • Absolute certainty that there is a God is down vs. 10 years ago (54% vs. 66% in 2003).
  • Outside of specific religious samples, the groups most likely to be absolutely certain there is a God include blacks (70%), Republicans (65%), older Americans (62%), Baby Boomers (60%), Southerners (61%) and Midwesterners (58%), and those with a high school education or less (60%).
  • There continues to be no consensus as to whether God is a man or a woman. Nearly 4 in 10 Americans (39%) think God is male, while only 1% of U.S. adults believe God is female. However, notable minorities believe God is neither male nor female (31%) or both male and female (10%).
  • 19 percent of Americans describe themselves are “very” religious, with an additional four in ten (40%) describing themselves as “somewhat” religious (down from 49% in 2007). Nearly one-fourth of Americans (23%) identify themselves as “not at all” religious – a figure that has nearly doubled since 2007, when it was at 12%.

The Harris Poll has some not-so-good news to report, as well. According to the pollsters, more Americans believe in ghosts, reincarnation and UFOs than in 2005:

  • Reincarnation: 25%, up 3%
  • Ghosts 42%, up 1%
  • UFOs 36%, up 1%

I’m not sure whether to blame this lapse in critical thinking on ‘reality” TV or the internet. Either way, it’s troubling.

Belief in witches is down to 5% to 25%, and belief in astrology remains unchanged at 29%. Belief in angels is down 6%, but still staggeringly high at 68%. Imaginary beings are losing followers, while pseudoscience still hangs in there. The good news, if one reads it thus, is that belief in the science of evolution is finally higher than the belief in witches, ghosts, UFOs, astrology, creationism and reincarnation. But not angels.

We have heading up for your net


Spam cartoonI have to admit that I frequently read the spam comments WordPress traps for my moderation, and I often do so with a smile. The clumsy, crazy constructs, the awkward English, butchered punctuation and the twisted word use just make me laugh.

Yes, like everyone else, I detest spam, and I quickly delete the comments into whatever digital wastebin they descend to. But I often chuckle to read them first. They make me wonder: are they deliberately written poorly, are they the sincere efforts of someone struggling to learn English, words strung together in random order by a bot, or are they the result of some Google translation gone awry?

Some have question marks which suggest symbols from other languages that didn’t get through the translation process. or are they just machine constructs dropping in characters at random?

This one is a good example, taken from today’s lot waiting for the delete button:

Of training course exceptional post. We have heading up for your net. Usually publish with your very own encounter and share. Oh! really grateful.

Some read like odd poetry, if you parse them so. Take the above, for example and write it thus:

Of training course exceptional post.
We have heading up for your net.
Usually publish with
your very own encounter
and share.
Oh!
really grateful.

Okay, not great poetry. Reads like computer-generated poetry, though, doesn’t it?

Anti-Intellectualism: The New Elitism


Anti-intellectualismThere’s a growing – and disturbing – trend in modern culture: anti-intellectual elitism. The dismissal of art, science, culture, philosophy, of rhetoric and debate, of literature and poetry, and their replacement by entertainment, spectacle, self-righteous self ignorance, and deliberate gullibility. These are usually followed by vituperative ridicule and angry caterwauling when anyone challenges the populist ideals or ideologies.

As if having a brain, as if having any aspirations to culture, to art, to learning – or worse, to science – was an evil, malicious thing that must be stomped upon. As if the literati were plotting world domination by quoting Shakespeare or Chaucer. Or Carl Sagan, Charles Darwin, Richard Dawkins.

“The mind of this country, taught to aim at low objects, eats upon itself.”
Ralph Waldo Emerson, oration to the Phi Beta Kappa Society Cambridge, August 31, 1837.

Anti-intellectualism isn’t new – Richard Hofstadter wrote about it in 1963 - but it has become highly visible on the internet where pseudoscience and conspiracy theories have developed unchallenged into popular anti-science and anti-rationalist countercultures, many followed and accepted by millions.

Hofstadter wrote,

Anti-intellectualism is a resentment and suspicion of the life of the mind and of those who are considered to represent it, and a disposition constantly to minimize the value of that life.

He warned in his book that intellectualism was “on the run” in America. It still is.*

Just look at the superstitious Jenny-McCarthyites who fear vaccinations with the same religious fervour medieval peasants feared black cats crossing their paths. Or the muddle-headed practitioners and followers of homeopathy. The chemtrail conspiracists. The anti-wind turbine and the anti-fluoride crowd. Any Scientologist. Or any religious fundamentalist. The list of true believers in the anti-intellectual crowd is huge.

Online technology didn’t create these mythologies, or the gullibility of their followers, but the internet is the great equalizer and the great popularizer. It’s not making us smarter; in fact, it may be dumbing down a lot of folks. That’s because anyone, anywhere, can have his or her say and there’s no way to easily discern the intellectual wheat from the. abundant chaff without doing some hard thinking and analysis.

Technology has created the sense of entitlement that every comment, every opinion is of equal value, regardless of the context and the person making that comment. It’s the ultimate democratizer. But it’s a democracy where communication is reduced to the lowest level: the instant, the brief and the angry retort.

Facebook and Twitter don’t have categories that identify posters as more relevant or more important than others. If the prime minister posts on Facebook, he doesn’t get a gold box around his post that says he’s in charge of the country. If Stephen Hawking weighs into a Facebook debate about the nature of the space-time continuum, he doesn’t get a special icon that lets people know he owns this conversation.***

All messages we post have the same weight, the same gravity. There’s nothing to identify any post as more informed, as factually correct or even relevant. So it becomes easy to derail a discussion by spurious claims and allegations, but innuendo, lies or simply confrontational language.

We’re all equally important on the internet. One person’s belief in magic, superstition or conspiracies gets the same opportunity to be heard and seen as those about science and empirical fact. In the online land of the blind, the one-eyed man has no special significance.

Facebook image

We’re creating a world of dummies. Angry dummies who feel they have the right, the authority and the need not only to comment on everything, but to make sure their voice is heard above the rest, and to drag down any opposing views through personal attacks, loud repetition and confrontation.

When they can’t respond with an intellectual counterargument – as is often the case – the anti-intellectuals respond with the ideology of their peer group (see the religious content of the message in the image taken from Facebook on the left) or ad hominem attacks. Name calling. Belittling and demeaning the opponent.

Bill Keller, writing in the New York Times, said,

The Web culture is simultaneously elitist and anti-authoritarian…

But it’s not an elitism of wisdom, education, experience or knowledge. The new elite are the angry posters, those who can shout loudest and more often, a clique of bullies and malcontents baying together like dogs cornering a fox. Too often it’s a combined elite of the anti-intellectuals and the conspiracy followers – not those who can voice the most cogent, most coherent response.

Together they ferment a rabid culture of anti-rationalism where every fact is suspect; every shadow holds a secret conspiracy. Rational thought is the enemy. Critical thinking is the devil’s tool.

Survival of the Fittest


Herbert SpencerCharles Darwin has long been associated with the phrase, “survival of the fittest.” For a century and a half people have used it to refer to their understanding of his explanation of how species evolved.

But it wasn’t his. And it has obscured the understanding of Darwin’s own theory.

It came from a contemporary, Herbert Spencer. Spencer was a contemporary of Darwin – an English polymath:  philosopher, biologist, anthropologist, sociologist, economist liberal political theorist, utilitarian – and, by some accounts, an early libertarian. His ideas came from people like Malthus and Adam Smith (read more about his philosophy here). Wikipedia tells us:

For many, the name of Herbert Spencer would be virtually synonymous with Social Darwinism, a social theory that applies the law of the survival of the fittest to society; humanitarian impulses had to be resisted as nothing should be allowed to interfere with nature’s laws, including the social struggle for existence. Spencer desired the elimination of the unfit through their failure to reproduce, rather than coercion or state intervention to initiate their physical annihilation.

He wrote his interpretation of Darwin’s ideas in an 1864 textbook of biology:

“This survival of the fittest, which I have here sought to express in mechanical terms, is that which Mr. Darwin has called ‘natural selection’, or the preservation of favoured races in the struggle for life.”

Spencer was really trying to apply Darwin’s ideas to his own ideas about economics, class struggle, competition and politics. He also believed in Lamarckism – the inheritance of attributes gained in one generation by the next – which has long since been discredited. But whether you agree with Spencer’s views, his reduction of Darwin’s theory to a convenient axiom did the theory an injustice.

In the public mind, Darwin’s ideas about natural selection were confusing and challenging. They became conflated with Spencer’s ideas and somehow the phrase stuck – the Victoria era equivalent of a bumper sticker phrase. It became wildly popular, and was soon applied to social and political phenomena, not simply biological.

It was so popular as a catch phrase that in the 1869  fifth edition of his book, On the Origin of Species, Darwin – unfortunately – added this line:

“But the expression often used by Mr. Herbert Spencer, of the Survival of the Fittest, is more accurate, and is sometimes equally convenient.”

The problem is really in how the word “fittest” is defined. Like its sister term, theory, it has both a common and a scientific meaning.*

Survival of the FittestFittest, in Darwin’s sense, doesn’t mean the biggest, best, toughest, strongest or even the most competitive. It’s not the macho concept of superiority. It isn’t about power, control or brute force.

It means the “best suited for the immediate environment.” It has also been described as a “property of the relationship between the organism and the environment.” That might be a different colour, smaller size, less active. Whatever offers the best opportunity to survive and breed. Having offspring is key.

It’s a far more subtle notion than commonly used. As Wikipedia says:

Modern evolutionary theory defines fitness not by how long an organism lives, but by how successful it is at reproducing. If an organism lives half as long as others of its species, but has twice as many offspring surviving to adulthood, its genes will become more common in the adult population of the next generation.

Infestations, Microbes & Parasites


Micrococcus (Actinobacteria)Staphylococci, Corynebacteria, Actinobacteria, Clostridiales, and Bacilli. They’re the most common, but they’re not the only ones. Bacteria. Microbes. Yes, even parasites.  Living in your belly button. And on your skin. Your hair. But the belly button flora and fauna fascinate me the most.*

We’ve known ever since the microscope was invented that we had a population of hitchhikers living on our skin, scalp – and even inside us. The great Antony van Leeuwenhoek is known as the “father of microbiology” for his explorations through his fledgling, primitive microscope in the late 17th and early 18th centuries. But we are still learning about the biodiversity we all have.**

There was a recent story in the Atlantic that researchers had found, of 2,368 species of bacteria living in our navels recorded so far, 1,458 new species.

New as in previously unknown until some scientist stuck a Q-tip into his or her belly button and examined the results. Which is what they are still doing, exploring this brave new frontier in microbiology. It must have been one of those eureka moments.

Gawd, dontcha love science? To bold go where no Q-tip has gone before…

The Atlantic story opens:

Instead of taking your fingerprint, maybe police should swab our belly buttons with Q-tips. No, that’s ridiculous, actually. But the idea illustrates a point made by a group of North Carolina-based researchers in their new Belly Button Biodiversity (BBB) project. Last month, the group published results of their first of many experiments, in which they swabbed 60 belly buttons and identified a total of 2,368 species of bacteria. People’s individual profiles were snowflake-ily, bacterially unique.

Most of the microbes that live on our skin are harmless, and many are actually beneficial: they protect us from more virulent invaders. What’s remarkable is the sheer number and variety of them.***

The scientists at Your Wildlife wrote that among all those species, there are some common forms found in most navels:

Turns out, belly buttons are a jungle of microbial biodiversity: we detected over 2300 species! And get this, only eight of those 2300 species– we call them oligarchs – were quite frequent and abundant, present in more than 70% of the individuals we sampled.

Oligarchs. Make me think of the Politburo. Or Putin’s new Russian clique. What role do these bacterial oligarchs play in their micro-environment?

We’re an entire ecosystem, Scientific American tells us:

Over the past 10 years or so, however, researchers have demonstrated that the human body is not such a neatly self-sufficient island after all. It is more like a complex ecosystem—a social network—containing trillions of bacteria and other microorganisms that inhabit our skin, genital areas, mouth and especially intestines. In fact, most of the cells in the human body are not human at all. Bacterial cells in the human body outnumber human cells 10 to one. Moreover, this mixed community of microbial cells and the genes they contain, collectively known as the microbiome, does not threaten us but offers vital help with basic physiological processes—from digestion to growth to self-defense.

By the way, you can contribute to this ongoing research; check the notes at yourwildlife.org about how to help. The belly button experiment is over, as researchers assess their samples, but they are moving on to armpits, a whole new territory.

From 7 to 29. Should I be worried? Or just keep monitoring?


Peaksaver PlusSeven cents per hour. That’s what the energy monitor was showing me a moment before I plugged in the kettle. Then it jumped to 29 cents. Wow! And this is mid-peak time, too, my new energy monitor warns. Should I be worried?

Better cut back on the tea if I want to conserve energy.

It did the same last night when we turned on the microwave at dinner time, but that was off-peak. Still, that’s pretty high, compared to seven cents. Those two devices seem to be the biggest energy hogs we have.

I need to do some calculating, however, to figure out real costs. What does five minutes’ worth of microwave heating translate to in terms of KWH used, and costs? I need a new app…

Energy monitorI’m reading the real-time display on my new energy monitoring toy tool and it’s telling me a lot about how I use electricity. It gives me that geeky satisfaction of watching data flow, just having it in front of me.

I got it when I signed up for the Peaksaver Plus program through Collus/Powerstream. Collingwood residents would have received a notice about the program in their last utility bill. If not, you can read about it here.*

The program (for homes with central air only, it seems), offers a free digital, touch-screen thermostat (Peaksaver Plus) and the wireless In-Home Energy Display. Free. For both. As in no charge, no additional billing, no hidden costs.

The stick behind this magnanimous carrot is simple: to reduce energy usage. The thermostat is connected wirelessly to the utility’s computers. If the power demand on the grid looks like it’s going to exceed capacity and cause a brownout, the utility can raise the temperature of your air conditioning by two degrees for 15 minutes to lighten the load. Does it all by itself.

Seems like a pretty good idea to me. After all, we don’t use the A/C a lot, and even when we do, the effect is a small change for a short time.

It won’t affect the winter heat (which is gas), so why not? Everyone has to do their part for our environment.

We’ve been using programmable digital thermostats for a couple of decades now. They really make a difference to your gas bill. Not least of all because, since it’s programmed, you never forget to turn the thermostat down when you leave the house. Or when you go to bed at night. Plus they are more accurate than the old manual, analog system. You get 68 degrees when you ask for it, not 70 or 72.Besides, the digital thermosat is cool, very programmable, and touch-screen. Not quite an iPad, but nonetheless, it’s pretty neat. And it runs off power from the furnace – not on batteries like the previous one (which always seemed to go dead on the coldest nights of the year…).

Our gas bill dropped significantly when we installed one.
