Smokescreen
I wish I could be surprised by this news, but instead I am simply resignedly outraged:
Drug adviser sacked for comments.
The man has criticised the government – not just policy, but ministers themselves – based on their handling of the evidence regarding drugs such as cannabis, LSD, and ecstasy. They are hopelessly blinkered into a negative view of these narcotics, despite reliable and repetitive evidence to the contrary. I won’t go into great detail here because this is certain to hit the blogs written by those with far more knowledge and time to spend on research and writing these things up.
Suffice it to say I am once more disappointed in our government, though far from surprised. The only good I see coming of this is that perhaps – just perhaps – they will lose more votes in the impending election, and maybe even raise awareness of the hopelessly ignorant drug policies in effect in this country.
Provoked thoughts
Last night I went to see a talk by the great Richard Wiseman at Leicester Skeptics in the Pub. A most entertaining and interesting evening was had by all (if my own experience and that of my friends was representative). When we got home, we had a look at some of the things Richard has on his blog, and came across this video:
Of course we partook of the rather bizarre-looking ritual and by the end there was a great deal of space between my hands, while my partner’s had barely moved. This is of only passing interest, really. The really thought-provoking part came later when I considered this in relation to the next talk taking place in Leicester.
On the 18th of AUgust, Dr Christine Mohr is giving a talk about the links between imagination / creativity and belief in the paranormal. Perhaps it’s not immediately apparent where this is going, but bear with me.
The personality test from Richard Wiseman is (unless I am somewhat mistaken) an example of the ideomotor effect. It is not a stretch to suggest (indeed Richard does so himself, I think) a connection between this effect and greater imagination. Is there, then, a case to be made for a related connection between the ideomotor effect and belief in the paranormal?
I’d hardly be surprised if there were, but it just struck me as one of those neat little webs of interrelated causes and effects that make science (and fringe science, like psychology) so very interesting.
On a partly-related note, you might be interested to learn that movements are being made in the direction of establishing a Skeptics in the Pub event in Birmingham. Seeing as this is so close to my current residence, I’m trying to get involved in helping set it up. Hopefully I will have some solid news to report on this front soon, or at least a tentative update.
The Power of the Hypothetical
“So remember, when you’re feeling very small and insecure,
How amazingly unlikely is your birth…”In science, an hypothesis is a wonderful thing. It is the glimmer of imagination and possibility that can give rise to years of research and fascinating advances in our knowledge of the world. But it is still just the preliminary stage – when people say something is “just a theory”, they are thinking of the colloquial meaning which is more analogous to hypothesis. It’s a weak form of knowledge, little better than conjecture.
But the power of the hypothetical goes beyond that. In philosophy, hypothetical scenarios are often (or indeed exhaustively) used to examine arguments, beliefs, and assumptions – of which the subject is sometimes previously unaware of using / having / making. I’m currently leafing through a book full of such hypotheticals – called The Pig That Wants To Be Eaten. The title is perfectly demonstrative of the kind of thinking contained therein – thought experiments which are often semi-nonsensical, but which nevertheless challenge us to examine our underlying reasons for what we believe. IS it immoral to eat a pig that wants to be eaten (assuming it is immoral to eat one that does not)? And if so, why?
This is one of the reasons I so enjoy science fiction – there is such an immense crossover with so many areas of philosophy, and there is no better arena for bringing thought experiments and hypotheticals into the mainstream consciousness. Just look at The Matrix – how many people had questioned the very nature of reality, and the evidence of their senses, before watching that film? Every philosopher was familiar with the idea, of course – as it was an imaginative adaptation of Descartes’ hyperbolic doubt and evil demon hypothetical. But it wasn’t well-known, in the public sense of the phrase.Now it seems the hypothetical has been given yet more power – or rather, yet another facet of its power has been discovered. Previous to this recent research, people were often encouraged to promote a positive outlook in themselves by focusing on the good things in their lives, “counting their blessings”, as it were. However, studies into this method returned mixed results at best, and a new hypothesis was tested – that, rather than simply thinking about the positive aspects of one’s life, one should imagine what one’s life would be like had those things never happened at all. The contrast this creates between the present and the parallel (and negative) “possible presents” reinforces the positivity of one’s life.
So next time, instead of just thinking “it could be worse”, perhaps you should actually think about exactly how it could be worse. And how easily it might have turned out that way.

Breaking my silence to support free speech
It’s no surprise to those who read this blog that I’m kind of in favour of free speech – you know, just a bit. It’s one of the many reasons I’ve taken an interest in the ongoing legal battle between Simon Singh and the British Chiropractic Association. It’s also why I’m here to promote the Sense About Science campaign to keep libel laws out of science. I’ve added the badge to the side bar and I recommend you click on it. If you’re just too damn lazy to scroll down (and who could blame you?) here it is:
And with that, I leave you again. I apologise for my long silences of late, but we still have no internet access in the flat and with my new job I have a lot less free time than I used to when I was unemployed. Hopefully the former situation will resolve soon, and I’ll be back with you, boring your eyes out as usual.
All the best, dear hypothetical reader. Until next time.
Fictional Sceptics #6: Star Trek (part 2)
In my previous entry on the matter, I discussed how (early) Star Trek acted as a kind of utopian vision for secular humanism. I also showed that, despite how dated it can seem at times, it was always a highly progressive series – particularly in terms of race and gender equality.
This time, I want to examine the numinous aspects of Star Trek – that is to say, the ways in which it preserved the sense of wonder to an almost spiritual level while remaining secular. It is closely linked to the spirit of scientific discovery, and the kind of excitement exemplified by the likes of Carl Sagan in his Cosmos series, and Phil Plait at a new development or line of research. It is an important aspect of science and scepticism which religious people often claim cannot be found outside of supernatural belief systems.
There are dozens of examples I could use to illustrate this point; it seemed that every other episode of The Next Generation involved the crew investigating, researching or just sightseeing at some interesting nebula, supernova or what have you; sometimes it was the premise of the show, sometimes it was an incidental detail along the way – but it always managed to express that they were explorers and scientists first, experiencing the wonder of the galaxy first-hand.
The particular example I want to use today, however, is a little more complex. Those of you who read my footnote on the post-Roddenberry Star Trek in my previous post will know that I noted a drop in secular humanism as a theme after Gene Roddenberry’s departure. What I’d like to add to that is that subsequent series did seem to be more morally complex than TOS and TNG, and, while they were more accommodating to religion, they rarely – if ever – attributed to it powers that it does not and could not possess.The case of the Prophets of Bajor is a particularly interesting case. Here we have a hugely pervasive religion with a tremendous amount of power over its followers – and incidentally a vehicle through which the series can explore themes relevant to scepticism and religion. The interesting thing is that their “prophets” – spirits or gods, essentially – are real. That is, they are actual beings who reside within the stable wormhole proximate to Bajor.
It is interesting to note the contrast in reactions between the Starfleet personnel and the Bajoran clergy (for want of a better term) to the scientific discoveries made in the wormhole. Both are awestruck, but that’s where the similarities end. The officers, Sisko in particular, are desperate to know more about the wormhole and the beings that reside within in it – from what little they already know, the wormhole is stable because it was constructed by the aliens, and the aliens themselves do not experience a “linear existence” as we do, and thus have no concept of time. The Bajorans remain steadfast in their dogma, though at first it seems that the two can coexist – the spiritual definition of the prophets, and the scientific explanation of them.
But when a religious controversy springs up about the teaching of science in school, the tensions become clear. The question is asked as to why the station’s single school is teaching only about the science of the wormhole and not the spiritual dimensions acknowledged by the Bajorans (a majority of the students, it should be noted). The teacher is adamant that only the science will be taught, and that the school is not a suitable place for spiritual instruction. It’s a great parallel to the evolution/creationism debate.But to get back to my point, at no time does it seem that there is less wonder and beauty to be found through the scientific perspective as opposed to the religious one. Indeed, it seems as if the religious people, having caught a glimpse of the truth, immediately shut their eyes so as to preserve that glimmer of wonder, and, having instilled it with all their hopes and expanded it with their imaginations, are unwilling to then open their eyes and see the truth of the wonders – which is no less amazing.
The best thing about post-Roddenberry Star Trek is that it becomes more complex in terms of morality and personalities, and therefore far more relevant to the real world. It is no longer a Utopia, but perhaps more of a realistic cultural extrapolation of where humanity might find itself a few centuries from now.
Hampshire: The Report
Firstly, if you’ve not read my earlier post on the subject of creationism-in-schools advice being given to Hampshire County Council, go ahead and read up. I’ll still be here when you get back. All done? Good.
I have located a copy of the report I mentioned. It can be found here:
“Teaching About Creationism and Evolution in Schools”
It begins in a reasonable fashion – and in fact continues likewise until the section vaguely headed “Evaluate“. Up until this point, I’ve not had a major problem with anything said, and in fact it sounds like a decent attempt at providing support for conducting a debate on this matter. After that point, however, it all gets a bit Disco.
For instance, it is quite insistent on the difference between creationism and intelligent design, and actually uses the words “the scientific theory of intelligent design”. This is horrifically misleading, disingenuous and false. Intelligent design is not a scientific theory; it is barely an hypothesis (which, incidentally, is the word they use earlier in the report – consistency please?). Almost as bad is their use of the word “scholar” to describe such unthinking dogmatists as Behe and Minnich
What is also telling is that, despite the fact that the language being used seems to be pluralist, it is clear that the report is centered on a Christian worldview. Creationism is defined as “typically” conforming to Genesis and the Bible, whereas “Intelligent Design” apparently doesn’t. There is no mention (except through the most vague implication) that other faiths involve a creation myth. I know we’re nominally a Christian nation, but our non-faith schools are generally meant to be cosmopolitan in this regard.
There are numerous other reasons I dislike this report, including its quoting of William Bloody Paley and not the counter-argument from Dawkins et al; but the main question I wanted answered was: where is this debate intended to take place? In the science class, or in religious education?
I was disappointed. There was nothing there to suggest that this was being proposed as a discussion to have in a particular setting or context. It could well be that this report itself has a context of which I am unaware, and the text toward to top of the report was sufficiently indecipherable to allow that perhaps that information is contained within that section; but if this is not the case, and the debate is being offered regardless of context, then I have to conclude that the news items surrounding this report are misleading.
That is not to say that there is nothing to worry about. This report is indicative of a greatly disturbing trend in our education system: there is no doubt in my mind that this report was compiled by a creationist and that the intent behind it is to push discussion of intelligent design into places it does not belong. That being said, however, there are a few questions that still need to be asked:
1. Where are these discussions intended to take place?
2. Are they trying to get intelligent design discussed as a scientific theory?
3. How seriously is this report being taken?
4. Are there advisory bodies in opposition to, and on the same level as, SACRE (Standing Advisory Council on Religious Education) that are pushing the scientific, secularist viewpoint?I’m going to do my best to get answers to these questions, but until then I must conclude that the report is deeply worrying, but not as bad as it could be. Intelligent design is still not a part of the science curriculum, and this report doesn’t suggest that it should be.
Small Wonders #1: Evolution
My head is somewhat fuzzy with The Ill at the moment, so just a quick entry today in case coherence is in short supply.
What better way to inaugurate my “Small Wonders” series than with Darwin’s Theory of Evolution, something so often taken for granted? It seems common sense to say that life as we know it has evolved from less complex forms, and yet look at it more closely and it is truly an absolute wonder that one man (ignoring, as most of the world sadly does, young Wallace) formulated, researched, developed and presented a theory with such staggering implications for virtually every field of study.
It seems so elegantly simple, and yet at the same time mind-numbingly complex. “Species change over time” is the pithy, easily-understood summary of literally a lifetime’s work, and it has branches reaching off into innumerable other lifetimes’ works. Genetics; medicine; zoology; biology; even ethics and philosophy were profoundly affected by the dawn of the Theory.
I greatly recommend finding out more about this subject; there should be no lack of freely-available information at this of all times. It is quite simply one of the most important scientific breakthroughs of all time, and one which can be appreciated at any level – from its simplest summary to the greatest levels of detail.
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.
A New Hope?
I was among the many millions of people who tuned in yesterday to witness the historic inauguration of the 44th president of the U.S.A.. It was as superb a speech as I had come to expect from Obama, and it was nice to see and hear true oratory art return to what is arguably the highest public office in the world.But of course it is the content of the speech that truly matters, and here again he did not disappoint. Again he made history (to the best of my knowledge) by becoming the first president to acknowledge the existence and importance of atheists and agnostics in their inaugural speech. Even better than this, however, was the promise that science would be restored to its rightful place; the scientific community had been given promises along those lines throughout the campaign – and it was truly gratifying to see it given such prominence.
The overwhelming theme of the speech, however, had a distinct secular humanist feel, one of shared responsibility and a positive belief in society’s ability to effect change.
The future looks, despite the present dark, a lot brighter than it has for some time. Thank you to every American who chose hope over fear.
BCA vs Simon Singh
You may or may not be aware of the libel action being brought against Simon Singh by the British Chiropractic Association. But if you’re interested in finding out more, the current best sources are Holford Watch and the ongoing coverage at Jack of Kent.
The bad news is that the BCA aren’t backing off. The good news (as I understand it) is that this means that, as part of the “fair comment” defence, the evidence for and against chiropractic – in respect to the six named child health conditions – is centrally relevant to the case, and will be well and truly put in the spotlight.
An important point to keep in mind, however, is whether this is the correct arena for this matter. Should it really be a matter decided legally, when the legal concept of evidence is so far removed from the scientific one as to be almost indistinguishable? Sadly, it seems to be a symptom of the horrific state of defamation legislation in this country.
