You’ve probably heard that quote about how, if you hear the sound of hoofbeats, you should be prepared to see zebras, but expect to see horses.

What it’s getting at is that either horses or zebras would offer a perfectly adequate explanation of what you’re hearing, but one of them is rather more likely than the other. It holds less true if you happen to be exchanging aphorisms in the African savanna, but the basic idea still works, assuming you’re not in some unlikely scenario specifically tailored to unbalance your usual expectations. You can apply it to other situations, too:

If you hear beeping, expect a reversing truck, not an alien spaceship.

If you taste almonds, expect marzipan, not cyanide.

If you see homeopathy, expect a sham, not medicine.

If you see some bent stalks of wheat, expect some slightly trodden-on wheat, not aliens who travelled billions of miles just to make an easily replicated pattern while no-one was looking and then vanish without a trace.

Crop circles are a phenomenon in which patterns appear in the field of a particular crop, where the corn/maize/wheat/whatever has been flattened, usually by bending over and breaking the stalk near the base, in such a way that some sort of recognisable pattern is visible when viewed from above. They first started to take off in southern England around 1978, with farmers finding virtually perfect circles appearing in the middle of their fields overnight. Since then, they have become far more elaborate and complex. “Circles” no longer does justice to the intricate patterns and corporate branding logos that can appear overnight nowadays.

There was much debate among empassioned enthusiasts, people whose interest was grabbed by the strangeness of the phenomenon, for many years. There primarily existed two distinct camps with their own interpretations: either it was the result of a curious weather phenomenon – some kind of mini-cyclone appearing suddenly, with a very localised effect – or it had to have been caused by a particular intelligence, presumably extra-terrestrial in nature.

There were books published and TV discussions held, with ideas and assertions being thrown back and forth by either side, with nobody ever really getting a solid hold of what was actually going on. No aliens were ever caught in the act, no conclusive proof was discovered of visitors from another world. No sudden shifts in air pressure were ever shown to be able to have such a peculiar effect on wheat, without being observed in any other context, and the meteorological explanation became increasingly implausible as the complexity of the circles grew. People spent hours and hours, night after night, camping out near what they considered likely candidate fields where they hoped to be able to see first-hand the magical, mystical, mysterious process by which these circles were created.

One explanation often mooted from the very beginning was that it was all the work of “pranksters”, but this didn’t get much play among the dedicated enthusiasts. It just seemed silly. These crops were quite difficult to bend, they reasoned, and it wasn’t immediately obvious how an individual, or even a team of hoaxsters, could flatten a complete area of so much tall grass in such a short time.

Therefore, the reasoning went, aliens were much more likely. That was the only explanation which really covered all the bases without leaving any awkward loose ends or unconvincing assumptions.


You remember the zebras I brought up right at the beginning? In this analogy, the zebras are the aliens. And the horses are roughly analogous to “a couple of guys with some string and a piece of wood, who thought of a way to push some wheat onto the ground that’s slightly more efficient than whatever you could think of off the top of your head, and so gets the job done a bit faster than you might at first imagine”.

Specifically, our metaphorical horses (metaphorses?) are a couple of guys called Doug and Dave, who came up with the idea in a pub in the south of England in the ’70s, and only eventually owned up to it and started showing various media outlets exactly how they did it when Doug’s wife began suspecting him of having an affair. All the late nights and unexplained mileage on the car’s odometer that resulted from their hobby hadn’t gone unnoticed.

Unlike a lot of alleged paranormal phenomena, nobody disputes that crop circles exist. And moreover, the exact nature of their origins is also, in many cases, perfectly and abundantly clear. There are numerous people and organisations out there who we know do this kind of thing themselves. We have indisputable documented proof of some of these huge, intricate patterns being created by humans through entirely mundane means.

Of course, we only have proof that some such patterns were created this way. Not every single such circle has been created while a professional camera crew was present. Maybe aliens did create some of them. But this is like claiming that what looks like some dogshit on the pavement might have in fact come from a leprechaun. Why would you take the leap of logic to believe that, without some compelling reason not to go with the more obvious cause?

This means that, if anyone still wants to claim that some circles must result from an alien intelligence, their job is now to draw an absolute distinction between these two types of pattern – the man-made ones, and those of unquestionably alien origin.

And this is apparently rather tricky to do. It seems that the two types look a lot alike to a casual observer – or even, a lot of the time, to a supposed expert. There is no method consistently agreed upon of grouping one whole bunch together as being totally different from all the rest, and assigning them as likely candidates for alien creations. Experts have often pronounced particular circles to be undoubtedly alien, and then met the guys who knocked it together in 90 minutes. And while being proved wrong is an important part of any science, you also need to be able to refine your model based on the evidence that proved you wrong, such that every time you become a little bit less wrong than you were before. Cerealogists have never managed to get their shit together in this manner.

It often seems that all they have to fall back on is “It couldn’t have all been done in one night by humans”. But are they really the best authorities to trust on what is and isn’t physically possible? Have they actually crunched the numbers, or are they just arguing from personal incredulity? This was made overnight, by just a bunch of guys. Which might sound pretty unbelievable, but there it is.

None of the other ways that alien theorists purport to determine the extra-terrestrial origins of some crop circles seems to hold up either. Toward the end of Jim Schnabel’s fascinating book Round in Circles, the author describes some of the circle-making expeditions he went on, with some of the friends he’d made researching the history of the phenomenon. At first, come the following morning, the enthusiasts would look at the amateurish way the stalks were bent and immediately declare the site to be a mere “hoax”. But as he became more practised at it, he began to see the experts in the subject declaring their confidence that this particular pattern was indeed of alien origin, as they peered at stalks that Jim himself had trodden down mere hours before.

There is simply no reliable predictor of what to expect from a supposedly alien-generated crop circle. The features of the circles of provably terrestrial origin are often mightily impressive, and may seem to stretch the powers of human ingenuity, for anyone unfamiliar with just how that ingenuity can be applied in this field. We’ve seen them being mistaken for alien or paranormal phenomena many times, but it’s never been confirmed the other way around.

The human creation of fantastically impressive crop circles is a known phenomenon. We see horses galloping around us all the time, but never even a hint of a black-and-white stripe.
