It’s probably unfashionable to call it “Chinese Whispers” these days. At the very least, it’s politically incorrect, and as is so often the case in these situations, it turns out that the etymology of the game does include a racist streak. Namely; it was called this because westerners figured that spoken Chinese was unintelligible. So, a game where a message whispered from one ear to the next is eventually rendered nonsensical, was named for the Chinese “language” (which just goes to show how little was understood – were they listening to Cantonese, or Mandarin perhaps?)

So let’s call it “Telephone”, as it is called in the United States, according to Wiki, anyhow.

Really, that’s all by the by. What I’m here to talk about is the big picture.

There is a tendency these days to regard any item of news, or opinion from a talking head, as sitting on a level playing field with every other bit of news or opinion. A sense that one idea is as good as the next. It this world, the notion of “truth” ceases to have meaning, as if being “true” is a value judgment where none should be made. Just as the post-modern art era challenged the idea of “beauty” as a worthwhile goal in art, we now seem to live in the world of “post-truth”.

At some point, collectively we lost the ability to be able to distinguish an idea with merit grounded in observable facts, from an idea based upon another person’s opinion and ideas. This is a pretty big loss to society. If you can’t decide between things that are objectively true, and things that are mere conjecture, then you may find yourself completely lost in the world. Without this ability, airplanes would never have flown, and we’d still be cooking with a camp fire, and certainly would not have the ability to reheat our food in the microwave.

Somehow, we are fearful of value judgment. Some things, nonetheless, are more valuable than others. The effects of gravity are observable, for instance, and if someone were to say, “I have a different idea”, we might listen, but we would dismiss it as untrue at best, crazy more likely. Gravity is a fact. The warping of space-time causes bodies of mass to be “attracted” to one another in proportion to their mass (roughly – it’s easy to get your Newtonian and Einsteinian physics muddled up here, and that’s beside the point anyway).

So it is that even in the murky world of politics and international affairs, there is a version of events that is true, and myriad others that simply are not. The considerable difficulty lies in determining to which you have been subjected.

In to this quagmire steps the conspiracy theory. By definition, a conspiracy is a situation where a number of actors (people, groups, “governments”) get together and decide on a collective course of action, usually to achieve a mutually beneficial goal (perhaps at the cost of external parties), and normally protected by secrecy as to their intentions and as to the existance of the conspiracy itself.

In this sense, nearly all international government actions are conspiracies. They work to further their ends, and they keep the intentions and plans secret.

So what can this tell us? Well, if you’ve ever heard of espionage, spies, and the “intelligence community”, you’ll know that the conspiracies of one government are notoriously leaky and transparent to others. Sometimes through concerted effort, sometimes by mistake, in the end, secrets are hard to keep, even by those whose entire career is bent on keeping them.

Part of the problem is that we’re only human, we’re incorrigible gossips, and we just blab. We also suffer from various psychological tendencies, greed, pride, etc. Ultimately, someone lets the cat out of the bag. The more people who are in on the secret, the more probable the leak. As they say in the classics, The Truth Will Out!

As such, grand actions by a nation state, plans involved large numbers of people, plans shrouded in mystery and secrecy, rarely stay secret for long. It’s just highly difficult to keep the secret.

Also, the more people involved, the greater the work of co-ordination, which by itself requires more people who know of the secrets. It’s nearly an exponential growth of numbers of likely blabbers. The bigger the conspiracy, the larger the likelihood of a leak, therefore the less likely the secret will be contained. Multiply that by the time the conspiracy has been in place, and you get an even slimmer likelihood of success.

In short, big conspiracies are very unlikely indeed.

Let’s return to the co-ordination problem. Remember the game, Chinese Whispers Telephone? Well, the more people in the circle, the worse the end result. With enough people, it becomes complete gibberish by the end. That’s how the world of conspiracy works too! Sure, computers mean perfect messages can be copied instantaneously, but there are still people either side of the machinery. There’s still heaps of room for human error. Couple that with the secrecy problem and you have a near perfect recipe for failure.

So, the simplest answer to your next conspiracy theory, be it chemtrails, big-pharma/GMOs/Aliens, climate change (I mean look what happened to the emails of a bunch of giggling scientists – even their snarky emails couldn’t be kept secret!), Syrian war… whatever, it is this:

The bigger the conspiracy, the more unlikely it is.

More than that, beyond a threshold (lets say, collusion by a couple of countries, or multi-national companies), it becomes basically impossible. If you add natural commercial market competition to the mix (as there is in say the reporting of the news) then the threshold reduces. Next time someone tells you that the media is feeding you a lie, ask them to think of how that might work. The sensible end to that thought is, “It doesn’t.”

PS. This is not exactly the same argument as Okham’s Razor. Indeed you might think the Razor suggests that a conspiracy is the simplest solution given that perhaps it involves the neatest arrangement with least variables. But no, from the Razor, the most likely solution will never be a conspiracy, because it is quickly seen that to have a conspiracy is always to posit one more variable (namely the conspiracy itself) than is required to explain the phenomenon. Thus conspiracies nearly always fail the test.

 

 

Seen on Facebook: “Part of the reason we have diseases is because of the shit they put in the vaccinations.”

Then they argued against vaccinations. The usual followed: That vaccines cause autism (a scientifically discredited idea) and that ‘other chemicals’ in the vaccines cause disease by ‘attacking our organs’ (actually, such chemicals are in significantly lower concentrations in vaccines than in most foods and drinks). They then ‘agreed to disagree’, demonstrating no flexibility on the issue. It is terribly frustrating given the important benefits of a major public health measure.

What is going on here? Why do people believe the wrong story in the face of the overwhelming scientific evidence?

The answer is not that they are stupid. It is likely a result of pernicious cognitive biases that we all share. We’re all pretty hopeless at assessing small risks and our brain is essentially useless when it comes to statistics. It’s not natural to think statistically and even statisticians don’t do it automatically. Most importantly here, we tend to construct arguments in our minds based on the easiest memories we can access. This is called “availability bias”, bolstered by its cousin, the salience of vivid events creating an overestimation of the probabilities.

We fixate on rare dramatic events, and they become etched into our memories with all the emotional adornments of terror and compassion. They are easy to recall, and we then construct stories and causation from them. A child gets very sick after a vaccination, we are horrified, we link that to a well publicised (but wrong) link between autism and vaccinations and hey presto! Vaccines are to blame. It seems to make sense and gives us warm feelings that we have understood the world and can proceed with that knowledge.

None of that process requires you to think hard. You do it almost automatically. In contrast, to actually examine the link requires deliberate thought. Any medical treatment carries risk, but it is usually exceptionally small, and mostly well worth discounting. We attach too much value to very slim chances. For instance, a small risk such as a 1 in 10,000 chance of an adverse outcome is, perversely, perceived as hugely worse than no chance at all, and so we tend to avoid the risk by avoiding the risky activity.

On the flipside, we are happy to accept the extremely high probability of losing money in a lottery because we cannot really grasp the vanishingly small chance of winning – but we have no trouble at all imagining the benefits! Don’t trust your gut on small probabilities.

Autism is not caused by vaccinations, but that fact is far less famous than the original headliner. So powerful is the availability bias, that it affects the news and this creates a cascade of availability, reinforcing your biases. People ask, ‘but what if it is true, shouldn’t we be cautious?’ That is your little availability machine speaking to you. Fight back, question whether the information you’re using is true. Extreme caution is warranted only in the face of true uncertainty; it should not be a default position. It hardly needs to be said that not vaccinating causes a significantly higher risk of disease spreading in society.

Your fast-thinking brain is very good at living, but it is designed to meet challenges that are simple in nature, like avoiding lions on the plains of Africa. It’s not so good at new complex ideas, but it can be, as long as you work at it. Don’t let your first thoughts pervade your life; instead, use your capacity for reason to enhance it.

This first appeared in print in my column in Woroni, the student newspaper of The Australian National University, 29 August 2013.

When I was young I wanted to be a SCIENTIST. I wanted to pour over the literature; I wanted to argue about method. I especially wanted to spend hours traipsing about the wilderness in search of tiny little things that may or may not help my research, and I then particularly wanted to spend back breaking hours in a laboratory dissolving things in solutions and then blasting them with heat and lasers and collecting gasses and measuring them to within inches of their lives.

Naturally, I had visions of spending hours in front of a computer calculating the statistics and determining, within certain bounds, the exact results, resulting in a mystical dream of writing up the research. Of course I would then have it go backward and forward between peers (each with their own particular flavor of review) and finally, after six good productive months of politics and writing, those results would be published in a journal for most of the world not to read.

Of course, none of the above is true. That was not my childhood vision. I mean, I didn’t want to be a fireman or anything like that, sure, but what I’ve just described? No thanks!

No, I had dinosaurs! I grew up in the time where it was discovered that it was an asteroid that hit Earth and killed them! I was a child of the time of ‘Transformers’, and I was especially proud of a T-Rex transformer that I had that none of the other kids did. In hindsight, that just made me a spoilt brat.

I watched the occasional documentary, mostly because my grandmother and mother encouraged it. I remember seeing David Attenborough crack open a rock to reveal a fossil. I guess it was a trilobite, can’t remember, but wow, I was amazed!

I also had politics. My parents always had the ‘adult news’ on at 7pm – the national news, and the current affairs after. If I wanted to spend that time with my mum and dad, I was watching that. I didn’t have half a clue what these people were on about, but clearly it was important. My subsequent high school education ended up being all about science and mathematics, hardly surprising for a son of doctors. Although my best final marks were in English – pretty uncommon for a science and maths nerd.

Fast-forward about 10 years and I was studying science, specifically geology, at university. If you’re wondering about the time gap, I studied Law for about 3 years at one point, but it WILL NOT appear on my resume since I gracefully withdrew after, shall we say, attendance-related performance issues. I attended enough though to learn a bit about argument, or as they more commonly say, enough to be dangerous. I then worked in real estate for a year, which one might justifiable say that combined with my half-baked and inadequate legal training made me positively lethal.

So any way, after learning the art of snakes and snake oil, I went in to learning about rocks and well, other rocks. This 3-year journey of rocks and their interaction with other rocks and how they all relate to each other was so fascinating that I decided to do an honours project in geology for an extra year. In which I determined the age of some rocks from a costal area in my home state of Victoria (about 50 million years old, in case you’re wondering – I wouldn’t want to leave you hanging).

These rocks were basalts as it happens (like that which erupts from the volcanoes of Hawaii) but what is really important is that this got me out there, cracking open rocks and finding samples. It also involved considerable literature review and statistics and report writing. Remember the start of this essay?

One thing I did do while collecting little bits of rock was stand on a rocky shore platform looking for samples, all alone, in complete disregard of the risks. I am not exaggerating to say that I could have died that day. The water from that freak wave only reached my waist, but any further and I would have found myself in the water, possibly kilometers from land. It does happen. That’s why Universities don’t let people do what I did alone (actually they didn’t then either, I just kinda well, you know…)

Why am I telling you this? Well, it’s because there, there on that platform being hit with a freak wave, I did consider why I was doing it. At the time, I guess I just needed that sample. Badly – my degree depended on it! Plus, what a beautiful place to die! Only kidding.

Nine-odd further years later, I am asking the same questions, but this time, there are no freak waves. Since then, I’ve been staring at rocks and reports and trying to decide where the next big gold or nickel deposits might be found. I’ve worked for a couple of the biggest mining companies in the world, I’ve also slept in a swag in the middle of a frigid desert night between stints supervising dusty, loud drill rigs.

Through all of this, I have continued to have an almost child-like fascination in science and nature. I have read all the famous authors – Gould, Dawkins, Sagan, you name it. I watch the docos. I watch them again. I sometimes write stuff about things on my blog. I follow my little curiosities down the rabbit hole that might begin with a name, lead to a wiki search, and end in several journal articles and a whole new ‘issue de jour’ for the week. I get involved in skeptical arguments and pursue the philosophical reasoning they entail. I pity those around me sometimes; I suspect I am quite, as they politely say, “intense”.

So, I could tell you something about evolution, I could tell you a little about quantum physics (which is only to say, for example, that I could tell you about Schrodinger’s Cat, and also explain that no cats are involved). I could describe the Monty Hall problem and why it demonstrates how flawed our thinking can be.

Why would you listen to me though? I’m a geologist, not a philosopher, or physicist, or even a biologist. In fact, I have never done a single formal course in biology, and that includes school level biology (I did physics and chemistry and geography, there’s only so much room). I did read A Brief History of Time by Stephen Hawking, when I was in high school, but I’m not about to say I’m some sort of cosmologist.

I would ask you to listen only because it is interesting; for no other reason. I would appeal to your sense of intrigue. I am suggesting to you that the real world is far more interesting than anything that you might have seen in the Da Vinci Code or, God forbid, stuff about the megalodon shark in Shark Week.

The real world has every sort of mystery of the sort that Dan Brown wrote his fiction about. But the thing is, it’s not fiction. Even Brown’s fiction contains some real science and real history. And that is the point. Its not just science, it is history and culture too. They all link together to make this great big wonderful story. And anyone can be part of that. Anyone can be that investigator. The scientist at the frontline, and even, with time, the one that the President calls when the aliens land.

For that though you’re going to need skills. Investigative skills, particularly of the sort that can be verified and tested. And this is where you will need some scientific training. Or at least, a good appreciation of rational thought and how something can be known, objectively. You need to have an appreciation of why scientific reasoning has lead to the advances it has. After all, you trust planes not to fall out of the sky, right?

Either way, rejoice in your fascination for all things interesting. Science is not a specialized territory only inhabited by nerdy, bespectacled introverts who are always portrayed as nerdy, bespectacled introverts. In fact, most scientists are normal. Really, they are.

Most importantly, don’t worry if you don’t want to be a scientist. I was almost a lawyer, and there are plenty of other valid, interesting and important pursuits in life, and no, science is not the only ‘way of knowing’. All that said though, please learn about science and its methods. The modern world demands it.

 

Reposted from Medium: https://medium.com/architecting-a-life/369f86f61f79

ResearchBlogging.orgA famous study by the Church of the Flying Spaghetti Monster showed that as the global number of pirates has decreased historically, the climate has warmed up. That is, there is a negative correlation between increasing global temperatures and the number of pirates. The FSM drew on this link to demonstrate that pirates are devine beings and that their decline is responsible for global warming. Arrrhh!

Of course, this study was a parody. Whilst it may be true that there are less pirates today than when climate was cooler, this is an example of pure correlation, not causation. Pirates do not keep the climate cooler, there is no mechanism for them to do so, however, the correlation in the data cannot be denied.

At the other end of the scale is, for example, the negative correlation between increased vaccination rates and the incidence of targeted infections. This is a particularly strong negative correlation, but it also has a causative basis. This is because we know the mechanism by which a vaccine protects the vaccinated, and thus can predict that in a population, there would be a negative correlation as described. This is a causation relationship that results in correlation – statistically and scientifically, the strongest possible result. Put another way, it is a hypothesis about the positive benefit of vaccination that is strongly supported by the evidence.

In the middle is the great big grey area of intellectual inquiry, also known as ‘everything else’. Recently a large meta-analysis (a study of studies – comparing different studies to draw over-arching conclusions) concluded that there is a negative correlation between intelligence and faith (Zuckeman, Silberman and Hall, 2013). That is, the higher your intelligence (analytic intelligence, such as that measured by IQ tests) the less likely you are to be religious.

Your personal reaction to that result is, perhaps unsurprisingly, likely to be influenced by your opinion on religion, and your opinion on intelligence.  But what does this result really mean? Are religious people dumb? Are atheists smarter? Does high intelligence ‘cause’ un-religiousness? Does religiousness ‘cause’ low intelligence?

The short answer is ‘no’. This is just a correlation. It just suggests that on the whole, really intelligent people are less likely to be religious. However, this study went further, discussing mechanisms to explain the correlation, and here is where it moves into the area of causation.

Of these, perhaps most interesting is the notion of sense of control. A person’s sense of control over their lives is influenced by numerous factors, both internal (within their control) and external (outside of their control). The report discusses studies that have shown that if you challenge someone’s sense of control, their belief in God increases. This suggests that religion provides a means of explaining one’s life; that what you can’t control is in the hands of God (and isn’t it instructive here that we have idioms such as ‘in the lap of the Gods’?). Higher intelligence can provide a person with greater self-control, that is, they have the means to have greater control over their lives, therefore, less reliance on faith. They see and understand themselves as in control, not an external power. They also found that intelligent people are less conforming, thus less likely to be influenced by the dogma of religion.

The most common explanation they found though was that intelligent people prefer rational explanations to irrational ones. Analytical thinking is preferred over intuitive thinking. An intelligent person may view the world rationally on the basis of logical conclusions, rather that by some grand supernatural design. As a result, the build-up of rational conclusions results in a decrease in religiosity.

All this then suggests a causative mechanism – that higher intelligence fosters a greater sense of personal control and that a preference for rational thought processes reduces the need for faith, thereby reducing belief in the supernatural. If we were to take that as a hypothesis, we would expect to find, in a population, the exact negative correlation that was found if the hypothesis were to be supported.

Clearly though, I have made a circular argument, by taking a result, finding an explanation, proposing a hypothesis from that explanation, and then, completely unsurprisingly, getting the same result. Not good science on my behalf there. But what we can recover from this is that there might be a mechanism that accounts for the correlation, and that therefore, this is not simply a pure correlation. In other words, there might be a causative relationship. The existence of a number of studies that show psychological phenomena such as the personal control study discussed above demonstrates that there exists a way in which higher intelligence could lead to lower religiosity. Whilst this does not completely explain the negative correlation, it puts it firmly into the camp of ‘possible causation’, making the overall finding of a negative correlation important scientifically, pointing strongly towards the value of further research, especially into the psychological mechanisms behind religiosity.

Of course, whilst you’re not likely to be able to improve your IQ by reducing your faith, you could at least put yourself in the ‘upper half’ of the curve and tell people how you’re one of the intelligent ones!! 😉

Well that was ugly! A recent tweet from Prof. Richard Dawkins, probably the most famous atheist in the world, seriously upset people. His tweet consisted of neatly cherry-picked figures relating to the distribution of Nobel Prizes between Trinity College, Cambridge, and Islam. The point made, albeit incredibly droll and unenlightening, was that Islam had not produced as many Nobel Prizes as even just one very well regarded university college. His tweet:

“All the world’s Muslims have fewer Nobel Prizes than Trinity College, Cambridge. They did great things in the Middle Ages, though.”

Well that really stirred the pot, and the general complaint was that he was being a bigot, or as one writer eloquently put it “dressing up bigotry as non-belief”. It is hard not to see it this way.  I’m certainly not keen to get carried away on the ‘offensive’ argument, tending to agree with Stephen Fry on the value of claiming to be offended, but it was grossly provocative and quite lame, argumentatively.

Prof. Dawkins has responded in a longer blog post, and now we get to see what he really meant. His point is more subtle than the tweet and contains some interesting ideas (whilst also continuing on the theme of boring facts about Nobel Prizes though). To me, his longer post reminds me of what is great about Dawkins, and it is a crying shame that he has allowed his Twitter account to become a pariah.

“New opinions are always suspected, and usually opposed, without any other reason but because they are not already common.”

-John Locke, 1690

Revolutions are usually considered bloody affairs. In science, this is rarely the case, as those white lab coats do stain easily. It would seem crazy to think of science as having a revolutionary history, a sort of dialectic that puts one theory in the red corner and another in the blue. Science is normally thought to involve thousands of tedious hours of hard work gradually adding to our understanding of the world.

Yet we have already encountered the ‘Black Swan’ – that piece of evidence that refutes a hypothesis, and we have struggled with how to proceed from there. Standard practice would be to reject the hypothesis, and continue further research, and in fact, that is how the majority of science is conducted.

What happens when someone develops a new theory though, one that fully explains all the existing observations, but in a novel way? Sometimes, this shakes the foundations of science – new science can only progress in light of this new idea.

“Plurality must never be posited without necessity”

-William of Ockham

People prefer simple solutions to problems. This is pretty obvious – it takes less unnecessary hard work. So, does this idea apply in science? Welcome down the rabbit hole of the history and philosophy of science.

Ockham’s Razor is a hugely influential heuristic (rule of thumb) in science. The Razor provides a way to decide between competing explanations that are equally supported by the evidence at hand. It suggests that the favoured explanation is that which posits fewer variables.

However, we all know that science is not often ‘simple’. How do we translate this position to science? This is where ‘falsifiability’ comes in, a concept made famous by Karl Popper in “The Logic of Scientific Discovery”. If you cannot falsify a hypothesis, then it is not scientific. The famous example is “all swans are white”. By inductive logic, no amount of white swans can prove this statement; instead it is supported until a single black swan is found.

Falsifiability alone does not, however, reduce possible explanations to one. Competing theories may all be falsifiable, thus scientific. Having established that swans can be black or white, we propose three competing ideas: 1. All swans are either black or white. 2. All swans are either black or white, but location determines which. 3. All swans are either black or white, but location and the season it is in December determine which. Having taken samples from Australia and England to test these hypotheses, you would see that all statements are supported, however number 2 has an extra variable, and 3 has two.

Strict application of the Razor would suggest you accept hypothesis 1. However, the extremely strong correlation between location and swan colour suggests that 2 is also acceptable. In this case, you decide that the ‘simplest’ hypothesis is the weaker, because it has less explanatory power. That is, even though clearly swans are either black or white (hypothesis 1), the black swans are all in Australia, and so hypothesis 2 suggests an explanation determined by geography. What about hypothesis 3?  Well, seasons are dependent on location, and so the seasons variable is superfluous, regardless of how well supported it is by the results. We take hypothesis 2 and move on, because that result has thrown up new hypotheses (e.g. around species and evolution) – the very fodder of science.

Thus science aims to explain, rather than simplify. Ockham’s Razor is really about how to prefer an explanation, rather than about the most simplistic explanation. Sometimes the best explanation is very complicated, the point is that it is no more complicated than it needs to be to do the explaining. Many ‘conspiracy theories’ fall foul of the Razor for this reason–they introduce extra variables without improving the explanatory power – that is, the non-conspiracy hypothesis can explain all the evidence.

Things get interesting when a contradictory result is found by a new experiment. Does it really falsify the hypothesis, or should we modify the hypothesis? Should hypotheses be ‘backward modified’ like this to explain new data? Doesn’t this contradict everything I’ve just said? How the hell does science really work? This will be a tale for another day, where we meet people like Thomas Kuhn and Imre Lakatos, and encounter the anarchist, Paul Feyeraband.

This article first appeared in print in my column in Woroni, the student newspaper of The Australian National University, No. 8, Vol 65, 23 July 2013.

We do seem to be heading in dark direction. A world where we seek not evidence but instead opinions from friends and talk show hosts, a world where argument is all that is needed. A world, in short, where anything can be true if we only believe it.

In an attempt to keep the post short, I first observe that the Cassini spacecraft has taken its final look at Earth, an event mostly ignored despite its poignancy given its status as one of the last great exploratory missions to Space.

People, and the politicians who represent them, seem determined to look at short terms goals, especially financial, in the face of species-threatening climate change. (I wanted to link something there then realized there are too many examples…)

 ‘Journalists’ of science and technology seem comfortable to be creationists (apparently because the story is better).

Elections are contested as a race to the bottom for votes, rather than as a conversation on ideals, goals and aspirations for society.

In the face of this, the collective advancement of society’s knowledge seems to be localized to the ‘nerds’, and clearly the popularisation of nerds has done nothing to raise the status of their work. I’m glad I was never a fan of that American show, ‘The Big Bang Theory’ (somewhat more of a fan of its namesake though).

I remember laughing at a movie a number of years ago called “Idiocracy”. I now actually can see a day where humans attempt to feed crops with Gatorade and puzzle at why that doesn’t work.

We seem to have lost sight of the days when we looked to the stars and imagined how much more we could know, how much better we could be and pictured a glorious future for humankind.

I don’t know, perhaps I am prematurely a grumpy old man. Still, I do wonder how we can combat the level of unreason in society, and I fear where it will lead.

Proudly do I present to you The 43rd Scientia Pro Publica, Science for the People, the Loves, Lives and Learning Edition. It’s brought to you by Technetium, the element with no stable isotopes!

You may detect an antipodean flavour in this issue, with some excellent work included from Australia! My hope is that Scientia is a springboard for people to read about research and to read scientific writing by real scientists who (generally) are not paid by anyone to write what they write. Consider this as science “from the horse’s mouth”.

Scientia Pro Publica

As always, science bloggers are keen for commentary and review of their work, especially if they are writing about original research. This kind of peer-review gives science blogging its power and maintains its integrity. You really can get your fill of juicy science here.

Scientia Pro Publica relies on YOU, so be sure to submit your blog posts, or the best of others’ here. Future editions need hosts, and we need them EVERY WEEK now. The schedule is here. Also, Scientia has a Twitter account, and there is even one for all science, environment and medical blog carnivals here! Read the rest of this entry »

I am hardly the first person to examine the interview with Richard Dawkins and come out a little surprised. It has had a small rash of internet discussion, but being an Australian interview, has not yet captured the crazy creationist ire. Mostly it appears that neither Dawkins nor Denton did enough research on each other. This would have been an easier task for Denton than Dawkins given the quantity of material out there on Dawkins’ views and indeed his life. Denton is less famous outside Australia and has a career in journalism and TV making him perhaps more adept at only letting out what he wants. Either way, as one person said to me, Dawkins looked at Denton as though Denton was from Mars at some points throughout the interview. Denton’s style is usually to try and wrong-foot interviewees into revealing more about themselves by asking old-hat questions in unexpected ways. He triangulates on people, and it usually works, making him one of the best interviewers I’ve ever seen. Unfortunately, when faced with a person who is professedly largely ignorant on topics outside his own field, this tactic fails. This is what has happened with Dawkins’ interview. A very straight bat to Denton is a good form of defensive play. In fact I had never seen that weakness until this interview.

Dawkins has been accused variously of being ivory-tower-dwelling, arrogant, pompous, strident (one he is particularly fond of) and narrow minded. However, this interview made Dawkins look humble when he explained that he doesn’t think that people should be interested in him, but that he does want to contribute his scientific knowledge to the world. His ideas about the value of truth and evidence I think were profound in the sense that rarely do people talk about it like that – the distinction between his views about life on other worlds versus the tooth fairy (or god) were very interesting. Perhaps he is right about the influence of fairy tales on children to prime them for religion. At no point did he distinguish himself from anyone else or make himself seem superior to others. Which is interesting considering that is precisely the sort of accusation frequently levelled at him. I think he did a good job of elucidating the difference between “belief” and “faith” and even distinguishing between religious faith and the kind of “faith” a scientist has in another scientist.

No doubt those who don’t like Dawkins will hold that up as an example of a boring, nerdy man who wants to take Christmas and tooth fairies away from children. Which is a shame since that is not what he said at all… And remember that Douglas Adams regarded him as a close friend, so he cannot possibly be humourless!

People seem incapable of grasping a central point to the philosophy of Dawkins and co. That is that there are seemingly infinite sources of wonder in the real world. There are new and exciting things to discover, and well worn paths to hold dear. There is little harm to be done in exploration, as long as a proper ethic is taken to the task. Not from god do we get to an ethics, but from analysis and reflection on life and its interrelationships.  What is not known may never be known, but we do not yet know that! Wonder, beauty, love, happiness, suffering, these are all real things in the real world that do not require a heavenly explanation to make them worthy of experience. The methods of science have revealed to us much of which we would otherwise be ignorant. It is an ignorance that carries no bliss.

Perhaps Charles Darwin said it best, as he penned these words, a man no longer accepting faith, seeing instead a wonderful connection between natural processes over geological time and the diversity and beauty of life on earth:

“There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.”
