Something sinister: the left handedness of creation

I'm embarrassed to admit it but the first home-grown science experiment I remember undertaking was to explore the validity of astrology. Inspired by the Carl Sagan book and television Cosmos I decided to see for myself if, after centuries of practice by millions of adherents, the whole thing really was a load of bunk. So for three months I checked the predictions for my star sign every week day and was amazed at the result: I found them so vague and generalised that I could easily find something in my life each day to fit the prediction. A sort of positive result that negates the hypothesis, as it were. As a young adult I encountered people with a rather less sceptical frame of mind, and if anything their astrological information only reinforced my earlier results. As my birthday is on the 'cusp' between two star signs, I found that about half the astrologically-inclined viewed me as a typical sign A whilst the other half dubbed me a typical sign B. At this point, I think I can rest my case...

Of course, astrology is a very old discipline so it's no wonder it's pretty easy to see the cracks. Over the past forty or so years there have been several generations of authors with a slightly more sophisticated approach, paying superficial lip service to the scientific method. Although their methodology fails due to the discarding or shoehorning of data, this hasn’t stopped the likes of L. Ron Hubbard from making mints. To this end, I decided to generate a hypothesis of my own and test it to a similar level of scrutiny as their material. Thus may I present my own idea for consideration: evidence suggests that our universe was created by an entity with a penchant for a particular direction, namely left-handed / anti-clockwise. Here are three selected cases to support the hypothesis, although I cannot claim them to have been chosen at random, for reasons that will soon become obvious.

The first argument: in the 1950s and 60s physicists found that the weak nuclear force or interaction, responsible for radioactivity, does not function symmetrically. Parity violation, to be technical about it, means that for example massless particles called neutrinos spin in a counter clockwise direction if they are created by beta decay. Like many other fundamental parameters to our universe, no-one has an explanation of why this is so: it just is.

The second argument: amino acids are usually described as the building blocks of proteins, but in addition to those used to make life on Earth, additional types are found in meteorites. It has been theorised that life was made possible by meteorites and comets delivering these chemicals to the primordial Earth, but radiation encountered on their journey may have affected them. Whereas amino acids synthesised in laboratories contain approximately equal amounts of mirror image (i.e. left- and right-handed) forms, nearly all life is constructed from the left-handed, or L-amino acids.

The third argument: a new catalogue of observations using the latest generation of telescopes indicate that from our viewpoint most galaxies rotate counter clockwise about their cores. Of course it's been a long time since humans believed the Earth to be the centre of the Universe, but even so, this is a disturbing observation. We now consider our planet just an insignificant component of the second-largest galaxy within a small group at one end of a super cluster. In which case, why is galactic rotation so far removed from random?

So how do these arguments stand up to scrutiny, both by themselves and collectively? Not very well, I'm afraid. Working backwards, the third argument shows the dangers of false pattern recognition: our innate ability to find patterns where none exist or to distort variations into a more aesthetic whole. In this particular case, it appears that the enthusiasts who classified the galaxies' direction of rotation were mistaken. Put it down to another instance of the less than perfect powers of perception we humans are stuck with (thanks, natural selection!)

The second argument initially bears up somewhat better, except that I deliberately ignored all of the biological elements against the argument. The best known of these is probably DNA itself, which is primarily helical in a clockwise direction. This seems to be a fairly common problem in the history of science, with well-known cases involving famous scientists such as Alfred Wegener, whose continental drift hypothesis was a precursor of plate tectonics but who deliberately ignored unsupportive data.

The first argument stands by itself and as such cannot constitute a pattern (obviously). Therefore it is essentially worthless: you might as well support the left-handed notion by stating that the planets in our solar system orbit the sun in a counter clockwise direction - which they do, unless you happen to live in the Southern Hemisphere!

Once again, our ability to find patterns where none exist, or as with the rotation of galaxies, to misconstrue data, leaves little doubt that our brains are naturally geared more towards the likes of astrology than astronomy. Pareidolia, the phenomenon of perceiving a pattern in a random context, is familiar to many via the man in the moon. However, there are varying degrees to this sort of perception; I confess I find it hard to see the figure myself (try it with the image above, incidentally taken through my 130mm reflector telescope earlier this year – see Cosmic Fugues for further information on genuine space-orientated pattern-making).

Of course, these skills have at times combined with innate aesthetics to aid the scientific enterprise, from the recognition and assembly of Hominin fossil fragments from the Great Rift Valley to Mendeleev's element swapping within the periodic table. However, most of the time we need to be extremely wary if a pattern seems to appear just a little bit too easily. Having said that, there still seem to be plenty of authors who cobble together a modicum of research, combine it with a catchy hook and wangle some extremely lucrative book and television documentary deals. Now, where’s a gullible publisher when you need one?

Let us think for you; or how I learnt to stop worrying and just believe the hype

I was recently watching my cousin's sister-in-law (please keep up) on a BBC TV documentary, in which various Victorian super-cures were shown to be little more than purgatives thanks to ingredients such as rhubarb, liquorice, soap and syrup. Whilst we frequently scorn such olden days quackery, the popularity of Ben Goldacre's Bad Science and (Patrick) HolfordWatch show that times haven't really changed all that much. Bombarded as we are from the egg with immense amounts of consumerist 'information', it is maddening if unsurprising that we buy the dream with critical faculties switched firmly off.

As Goldacre points out, George Orwell noted that the true genius in advertising is to sell you both the solution and the problem. Since the above sites both detail some of the rather more bizarre pharmaceuticals on the market, I'll recommend you visit them for further information. The material dealing with a council allowing a trial of fish oil pills to boost school exam results is priceless.

Yet this area is just one of several related to the solution/problem model, namely that there is consumer product for every issue: "Want a smart child? Just buy a Mozart CD!" The Mozart Effect may finally be heading for the debunked heap, but it's small fry compared to the notion that pill-popping is often the most effective yet rapid remedy. The amount of health supplements now available (carefully niche-marketed, of course) is astonishing, as is the appeal for us to treat ourselves like professional athletes, thanks to the increasing obsession with hydration and hypertonic drinks and 'wellness' in general.

The past two decades have seen a sad litany of scandals involving food and pharmacology, from the salmonella in eggs to the MMR vaccine and autism. With the UK press only to willing to whip up a scandal without prior thorough investigation of the evidence (for the most part, presumably for the sake of sales rather than any anti-scientific leanings per se), the public has been cried wolf to so many times it's enough to make you turn your back on anything that looks vaguely scientific. I don't know enough about the avian flu and swine flu hyperbole to comment in detail, but there too the media reporting of Government planning has implied elements verging on the farcical.

So what have we learnt so far? Firstly, it's far easier to push a one-size-fits-all cure than to individually assess people's physical and mental health problems as if they were, well, individuals. Most of us rely on the media for our explanations of health and food science issues, and these reports tend to appeal to the emotions and intuition rather more than we might find in the primary reports, AKA the 'sterilised pages of scientific literature', as palaeontologist Richard Fortey refers to it.

Not that most of us would have the time to plough through and decode the latter anyway, which brings me to a second issue: there is now so much freedom of choice, and an emphasis on rapid pacing to match our speed of communications that 'noise' (not just aural) is increasingly blocking critical thinking. Twenty years ago, people could define their day as having a work part and a leisure part, but now the two are blurred if not superseded thanks to a wide variety of recent technological innovations. Obviously we can work longer hours (i.e. from home or in transit) via mobile computing and Wi-Fi, but there’s also online networking, blogging, email and webcam, online shopping, even printing our own photos and ploughing through endless television channels 'live' or on-demand. It's a nice thought that when electronic personal assistants can be tailored to our personality profiles (like an uber-Amazon personalised homepage), then we will no longer be slaves to the labour-saving devices we clutter our lives with. But even then, will consumerist culture trivia remain a primary component of our lives?

If all this sounds a bit Luddite, or just plain anti-Capitalist, then why not ask yourself do you feel technically savvy and cool, thanks to owning a range of up-to-the-minute high-tech consumer items? Do you even have a nutritionist or a lifestyle coach? Consider is it possible that you could be losing common sense, handing over large chunks of analytical thought to others so as to gain a little bit of quality time in a hectic world? It’s up to us to reclaim our critical thought processes before we evolve into H.G. Well's passive, leisure-obsessed Eloi. Otherwise the future's bright, the future's hyper-realistic 3D with added gubbins! Now where's my isotonic rehydration fluid?
