Ignorance and Obfuscation

Half of Britons do not believe in evolution, survey finds.

"More than one-fifth prefer creationism or intelligent design, while many others are confused about Darwin's theory."

Right from the start, we have a misleading headline which suggests (not explicitly, but leaves open for misinterpretation) that half of Britons are creationists. In fact it's less than one quarter.

The real story here is that, to my mind at least, the creationist campaign - particularly that of intelligent design - has succeeded in blurring the issue. While I don't know that more people believe in creationism, I think more people are under the impression that there is doubt where no serious rational doubt exists. I can't seem to bring the previous figures to hand, though - so if you know what they were, please let me know - particularly if I've got it wrong. I wouldn't be surprised if this poll returned the exact same results as last time, actually. It wasn't that long ago. Also, let's not go over the many ways this data could be skewed - I'd at least want to know what questions were asked before trying to draw any sensible conclusions.

I'm all in favour of having these issues out in the open where they can be discussed, but that's not what we're dealing with here. Creationists are campaigning to get their rubbish accepted to the same degree as evidence-based theories, and disguising it under the banner of freedom of speech and open debate. Scientists are not blameless, either - more needs to be done to promote the public understanding of science, which would hopefully prevent a quarter of people from simply being "confused" by evolution. Those who bear the overwhelming burden of responsibility here, though, are the media; while there is a great deal of good science on the BBC and elsewhere (Attenborough being the absolute pinnacle), there is too much dumbing-down, and ignoring of science stories in favour of sensationalism and big headlines.

There is no easy solution, nor one single person or group to blame. What I do know is that 50% is too high a proportion of the population to be in any serious doubt about the theory of evolution.

The importance of antidote

There are many reasons I see such a strong link between philosophy and scepticism. One of these is probably bias on my part, being a great lover of both and prone to making connections. Another prominent reason, however, can be summed up in the word therapy.

While in other contexts this is a word which would set off some alarm bells - it's one which is used extensively by Supplementary, Complementary and Alternative Medicines (my favourite acronym) to give the illusion of competence where none exists - in this context, it is therapy of the most genuine and beneficial sort.

Acupuncture ModelPeople suffer from misconceptions. It's just a fact of life that this is the case, and there's nothing we can do to completely prevent this on a global scale. What the philosopher or sceptic is able to do is analyse an argument or a stated position, and identify fallacies. They can then determine the appropriate way of dissuading the person from that misconception (though of course there must be a degree of willing on the part of the subject). This diagnosis-treatment approach is why this particular brand of philosophy is known as therapeutic - and the parallels with scepticism are striking.

This process in scepticism is aided substantially by the wonders of the interwebs and the ever-growing freedom of information. Someone insisting that acupuncture or homeopathy has a proven track record in clinical trials? Ask to see the published research - or better yet, show them the reams of research which contradicts their position.

Of course, an important part of any therapy is to treat primary causes rather than the symptoms alone; and the source of so much of the ignorance and misunderstanding in the world is the mainstream media. For the majority of people, who do not get their news from the internet, the main sources of information are television and the dead tree press - the worst of which are the tabloids. It seems impossible for a story to appear in The Scum that isn't in some way serving the editorial agenda, every story spun to promote the paper's pet worldview.

An example: for one reason or another, lately there has been a rise in awareness of knife crime in the UK; the government is pledging new measures to combat it, and the opposition are using it as further "evidence" that society is going down the pan. The latest crime survey figures were recently splashed across the headlines - crying out things like "crime wave" and "a stabbing every 4 minutes in Blade Britain".

Now, I've spoken before about the evil of statistics in the media, and this is another case of the media twisting the figures to suit their agenda. This is where we need our antidotes, and there are few as effective at bursting the hyperbolic bubble of social commentary as Obsolete, and in this case he certainly doesn't disappoint. His entry on the subject reveals the figures behind the hysteria: 6% of violent crime in England & Wales in the last year involved a knife.

Without going into too much detail (head over to Obsolete's article if you want the full load), the basic point here is that crime is down - and even knife crime in particular has seen a (albeit statistically insignificant) decrease in the last year. Where, then, does this apocalyptic vision of a Broken, Blade-wielding Britain come from? Speculatively, I would have to say that it's probably the media themselves; though the Why is a different matter.

But can you imagine how hard it would be to get the facts were it not for the internet? How much more widespread the influence of the media would be? I shudder at the thought, to be honest.

The internet is a wonderful resource, and one of the best uses to which it can be put is as part of the therapeutic process of scepticism, treating misconceptions and bringing the "antidote" of actual facts to a wider audience.

Lies, drinking, damn lies, crime and statistics

Britain recently passed a licensing act which essentially allowed drinking establishments to remain open as long as they liked. While this is an oversimplification, it serves the purpose; essentially this has meant that all pubs no longer have to close at 23:00, nor all clubs at 02:00. There was great controversy in the media at the time, and fear that this would lead to a rise in binge-drinking and alcohol-related violence and other crime.

Little surprise, then, that there has been much talk in the last week of all their fears being proven true. Both the Telegraph and the Daily Mail have carried stories to the effect that the new 24-hour drinking laws have fuelled a rise in crime in the UK. This is one of the first things I was taught about in my politics undergraduate course: statistics in the media.

What the new drinking laws have actually led to is a rise in crime figures. This is because the police no longer have to deal with a flood of drunken people on the streets when every pub or club in the area kicks them out; they are no longer overwhelmed, and can actually catch and report a greater number of crimes. This "rise in crime" is in the statistics only, and was entirely predicted and intended by those who designed the law. A quote from a police officer (on Daily Mail Watch) supports this:

"The licensing act (24 hour) has also helped a great deal. Instead of kicking-out time for everywhere at 11pm, we’ve got slow dispersement into the night, so the police haven’t got a great mass of people all at once. Crime has ’shot up’ after the licensing Act because we CAN detect, arrest and deal with more people, rather than be swamped and therefore unable to arrest/detect any crime at all! This ‘crime-spike’ was intended by the Home Office and the police as a result of the above reason, but you won’t read that in the Daily Mail!"

Always be wary of statistics, particularly ones concerning crime.
