The difference between science and magic

Clarke’s Third Law: Any sufficiently advanced technology is indistinguishable from magic.
– Arthur C Clarke

Harry Potter bursts back on to our screens again this week, with the final book split into two no-doubt lumberingly ponderous full-length motion picture “events”. But, we must take solace in the fact that a) it will soon all be over and b) remember that magic has been a huge part of the fabric of narrative since stories began and try not to be too grumpy about the success of this “franchise”. If the appeal of stories is their ability to take us to places and show us things which ordinary life denies us, then it’s easy to see why magic should play such a strong part in especially early stories. Most fairy stories have a magical element – in fact the word “fairy” implies magic.

As we grow up, we leave such things behind, for the most part. The broad appeal of those Harry Potter books and films (and the amusing existence of editions of Harry Potter novels with “adult” covers and a £2.00 price premium) is a notable exception, but especially among male readers, although fairy stories are left behind, fantasy and especially science fiction stories remain popular.

I have observed before that the key feature of stories, the primary quality which distinguishes story from not-a-story is cause and effect. Without cause-and-effect, all you have is a succession of images. (Ironically, if you present such a succession of images to an audience, they are apt to invent the missing cause-and-effect, justifying the action they see in terms of A causing B, such is the storytelling hard-wiring in the human brain.)

Even in stories which don’t present themselves as fantastical, we can often see cause-and-effect being applied in a very limited way. Consider the phenomenon, often noted in pulp, pop or escapist fare, of “goodat”. If characters suddenly announce some convenient talent, skill, expertise, relationship or ability hitherto unmentioned and unsuspected, the audience is likely to feel cheated. “Oh, didn’t I mention I can speak Japanese / crack safes / recite pi to 150 decimal places / fly unaided / control birds with the power of my mind?” It doesn’t matter if these powers are magical, merely require talent and/or practice or are borderline. Conversely, however, if it is set-up that the character in question is “goodat” languages / escapology / mathematics / psychokinesis / animal sympathy, then the audience will probably accept almost any manifestation of this ability, no matter how fantastic. The archetypal version of this would be – as I think Eddie Izzard noted – the ability of someone who is goodat computers to hack into any system in a matter of minutes, just by waggling their fingers lightly over the keyboard and announcing “I’m in”.

So far, so fair enough. Storytellers take short cuts but even bad ones stop short of outright cheating. But there’s a difference between someone, for example, using their total mastery of Spanish to eventually make communication possible with a person who speaks only Catalan – and on the other hand, somebody uploading a Macintosh virus to an alien computer. I suggest that the latter is magic and that the distinction lies in the cause and effect.

Let’s pause for a moment and consider three ways in which a fictional person may be made to disappear before our eyes – Star Trek transporters, Star Trek phasers and Harry Potter vanishings. In Star Trek as you may know, a device known as a transporter is able to whisk people from one location to another. In effect, this device disintegrates the body at one end, transmits only the pattern (transmitting data is much quicker and easier than moving mass I suppose) to the other end, where it is reassembled. The practical difficulties of achieving this are not to be underestimated. A human being is composed of around 10^25 atoms, the exact location and type and state of which all have to be recorded. That’s a heckuva big file. This data is then transmitted to a precise location where no specialised machinery exists, and then the original body is reconstructed out of – what exactly? The TV shows, films and books are generally vague on this point.

But you could (and I’ve no doubt others have) construct vaguely plausible theories about what is going on here. The transporter pad creates a sort of cone or column around the person to be “transported” and everything within that column is processed. 23rd century computers have to “lock on” to remote locations. Maybe something like a tractor beam (not that that exists yet either) is used to process atmospheric atoms within a similar column at the destination in order to make the mass required to reconstruct the transportee. It’s a hugely big problem, but as presented in Star Trek, a hugely big solution is required to make it all work – and sometimes it doesn’t. It can go wrong, with horrible consequences. So this is borderline, but I would say, provided one makes allowances for three hundred-odd years of technological advancement, there is cause-and-effect here, and crucially, the cause (although we can’t examine it all in detail) seems sufficient for the effect.

Now compare those instances with death-by-phaser. Here’s a YouTube video. Watch the phaser deaths that occur around the 1’05” mark.

A phaser beam hits someone and they simply disappear. On a very basic level, there’s cause-and-effect here. Pull trigger on phaser, phaser beam hits redshirt, redshirt disappears. But what do we suppose the phaser beam is doing? It’s not just a narrow pencil-thin column of heat, it doesn’t drill a neat hole through its unfortunate victim. It’s not affecting the air between the barrel and the target, so it’s not radiating out a destructive cone – that would also affect surrounding matter, or if you were too close, not get the whole target. No, the phaser, or the beam itself, just “knows” what is target and what isn’t, what is to disappear in a flash and what is to be left unaffected. Not only is there no plausible mechanism by which this information could be imparted, the presentation doesn’t even begin to hint at a possible solution. Transporters are almost certainly impossible, but at least the series waves its metaphorical hands in the direction of a proper cause. Here the given cause is far to slight for the actual effect.

So, to me, death-by-phaser is far more like a wand being waved and a word being spoken and a Harry Potter character vanishing into thin air. No mechanism exists to define the scope of this action. No care must be taken to isolate only that which you wish to vanish. The waving of a wand and the saying of a word are in no way sufficient to account for the immensity and the complexity of the action which results – which is why Harry Potter is magic and not science-fiction. But magic gets smuggled in under our noses all the time. “I’m in” is a form of magic, as is the bus jump in Speed as is Radar’s ability to anticipate Colonel Blake and so on. The rule is – if the cause is sufficient for the effect, then what you have is science, but if the cause is insufficient for the effect, then what you have is magic.

But this applies to the real world of knowledge, science and medicine as much as it does to storytelling. Remember that humans look for cause-and-effect even where none is present. So, in earlier times, we ascribed the sudden and unpredictable shaking of the earth to the wrath of peevish gods. But since we have no idea where these gods are, what we have done to annoy them, or how they physically interact with the earth to cause such violence, this is magical thinking. Modern plate tectonics provides a much more thorough model (although not yet quite complete) with all the cause-and-effect you could wish for.

Another area where this test can be applied – one familiar to regular readers – is that of homeopathy. Both homeopathic and pharmaceutical treatments for a given condition, joint pain say, have the same superficial cause-and-effect appeal. You take pill. Pill makes pain better. But ask the chemist how their pill works and the answer will include fantastic quantities of detail, each element enhancing the cause-and-effect in the account. Non-steroidal anti-inflammatories inhibit cyclooxygenases, leading to a decrease in prostaglandin production. Opioids bind to and activate opioid receptors in the body’s tissues, and so on and so on. As with plate tectonics, the account may not yet be complete, but gaps are acknowledged, and effort continues to plug them. Pharmacology is science.

With your homeopathic pill on the other hand, the explanation is far sketchier. Like cures like, you may be told. How? It just does. Dilution increase potency. How? It just does. Does that mean half a pill will be twice as powerful as a whole pill? No, you have to dilute and the succuss (shake). What does that do? We don’t know. A cursory examination of the cause-and-effect supposedly driving homeopathy is enough to tell anyone that a woefully insufficient cause exists for the claimed results. Thus, we can confidently state that homeopathy is magic.

And, of course, the other thing we know about magic is that it isn’t real.

The real value in a “High Concept”

Posted on March 22nd, 2009 in screenwriting | No Comments »

What makes people go to the movies? Briefly: stars, spectacle and story. If your movie stars Jim Carrey or Tom Hanks or Julia Roberts, a certain number of people will turn out to see it come what may. There are also (a few) star directors like Steven Spielberg or James Cameron, and star “properties” like Batman or Harry Potter. Put that name or that face or that logo on the poster and you’ve already sold your first million tickets.

Next comes spectacle. If you can promise a rollercoaster ride, if you can promise jawdropping images, if you can dazzle your audience, you’ll pack ‘em in. Spectacle has meant different things in different eras: from Fred Astaire’s flashing feet, to the stunts and carchases of the 60s and 70s, to the CGI wonders of the 90s, and now it means Bourne-style “realism” more often than not. Advertising these things is not quite so easy, but you can certainly depict them on posters and they make good clips for TV shows and wonderful trailers.

Lastly comes story. A movie lacking stars and low on spectacle may nevertheless find an audience if the story is compelling – but how do you sell the story? You can’t give all the details away, so you have to just give a piece of it and hope that will be enough. The bigger a piece you have to give, the harder it is to communicate that simply and easily in the marketing. And that’s why High Concept is such a winner. High Concept means that your basic story idea can be a) summed up in a single short sentence, b) sounds exciting and c) has never been done before. High concept means a movie with no stars and no spectacle can still be sold on its story, and a movie with stars and/or spectacle has a third marketing route to help ensure that all that money spent on stars and spectacle won’t be wasted.

So, it’s easy to see why high concept is the darling of the money guys, and a millstone around the neck of a struggling screenwriter. I want to tell this intricate, complicated, heartfelt, truthful moving story. I don’t want it reduced to half-a-dozen snappy words. Well, maybe you should.

Conventional screenwriting wisdom breaks screen stories into three acts, and my feeling is that this is nothing more than reflecting an innate quality of stories, which in turn reflects an innate way in which human beings process information. A story needs a beginning, a middle and an end. It needs a set-up, a crisis and a resolution. The most prescriptive screenwriting manuals will give you page count targets for these things, and again they generally make sense for typical stories. If your screenplay is 120 pages and it takes you a lot more than 30 pages to set your story up, your story is all set-up and no action. If your major climax comes more than about 15 pages before the end, your story will feel like it fizzles out.

So, if you have an idea for a story, very often you know how to start it, so those first 20-30 pages can almost write themselves. And either you know how the story will end, or you know you won’t know how it ends until you get there, so in either case there’s no point worrying about those last 10-20 pages. Act one – no problem. Act three – no problems. It’s the 90 odd pages of act two that come in between, that’s your problem.

And that’s the real value of high concept.

A high concept idea gives you act two.

Let’s briefly compare two well-known supposedly high concept films: Tootsie and Indecent Proposal. Both films made money, because both were sold on their starpower and their high concept, but Tootsie made quite a lot more (adjusted for inflation) and was a critical success, whereas Indecent Proposal was critically derided and is now largely forgotten.

Let’s look at their high concept pitches. Tootsie: An actor with a reputation for being difficult to work with dresses up as a woman to land a role. Indecent Proposal: A billionaire offers a married couple a million dollars for one night spent with the wife. Do each of these fulfil the criteria outlined above? Both can be summed up in a single sentence. Both sound exciting, variously bringing with them secrecy, ambition, sex, money and power. And both are reasonably unique; if anything, Indecent Proposal is fresher, since cross-dressing comedies have long existed.

What then is the difference? The difference is that the Tootsie high concept gives you act two. But the high concept in Indecent Proposal isn’t really a high concept at all. It’s a high set up. When you put the face or name of big stars on the poster, you’re promising exciting performances. When you advertise the spectacle of your movie, you’re promising exciting visuals. When you use your high concept to sell your movie, you’re promising exciting situations. What exciting situations are you promised by the logline of Indecent Proposal? None. It’s a single moral dilemma, which can only really be resolved in one way or the movie really would die.

So, it plods through an interminably long act one, finally getting Demi Moore on board Robert Redford’s yacht after an awful lot of talking, and then finally getting them into bed together (although we don’t actually see this). And then the consequences of this are… not much. Demi Moore wavers rather pathetically between Harrelson and Redford, there’s some dull talk about foreclosures, finally Harrelson gives away the million bucks and Moore comes back to him. The story lacks structure and feels arbitrary.

Now, look at Tootsie. This too spends a while getting Hoffman to the point where shaving his legs and putting on a dress is a viable option, and is working towards the moment when his true identity will be revealed (at which point the film will be over) but once she/he lands the part, the set-up itself gives you the following situations…

·         Sustaining the charade in the dressing rooms

·         Trying to pursue a romance with another actress who doesn’t know he’s really a man

·         Dealing with the advances of sexist men

·         Dealing with the sincere advances of genuinely nice men

·         Seeing the world from a female perspective and questioning his own behaviour towards women

The high concept gives you the whole of act two, which is what a high concept should do for a screenwriter. If it helps someone else later down the line to sell your screenplay, or even – glory be! – gets audiences to come and see your movie, great. But as a screenwriter, value those ideas which give you act two. Because act two is a bitch.

Ask yourself of each sequence: could this sequence exist in any other movie? When you have an idea for a movie, ask yourself: what unique sequences does this idea give me? If the answers are “no” and “lots”, you may be on to a winner.
