context_page_description: A crop circle, crop formation, or corn circle is a pattern created by flattening a crop, usually a cereal. The term was first coined in the early 1980s by Colin Andrews. Crop circles have been described as all falling "within the range of the sort of thing done in hoaxes" by Taner Edis, professor of physics at Truman State University. Although obscure natural causes or alien origins of crop circles are suggested by fringe theorists, there is no scientific evidence for such explanations, and all crop circles are consistent with human causation.
  The number of crop circles has substantially increased from the 1970s to current times. There has been little scientific study of them. Circles in the United Kingdom are not distributed randomly across the landscape but appear near roads, areas of medium to dense population and cultural heritage monuments, such as Stonehenge or Avebury. In 1991, two hoaxers, Bower and Chorley, took credit for having created many circles throughout England after one of their circles was described by a circle investigator as impossible to be made by human hand.
context_section_description: The scientific consensus on crop circles is that they are constructed by human beings as hoaxes, advertising, or art. The most widely known method for a person or group to construct a crop formation is to tie one end of a rope to an anchor point and the other end to a board which is used to crush the plants. Skeptics of the paranormal point out that all characteristics of crop circles are fully compatible with their being made by hoaxers.
  Bower and Chorley confessed in 1991 to making the first crop circles in southern England. When some people refused to believe them, they deliberately added straight lines and squares to show that they could not have natural causes. In a copycat effect, increasingly complex circles started appearing in many countries around the world, including fractal figures. Physicists have suggested that the most complex formations might be made with the help of GPS and lasers. In 2009, a circle formation was made over the course of three consecutive nights and was apparently left unfinished, with some half-made circles.
  The main criticism of alleged non-human creation of crop circles is that while evidence of these origins, besides eyewitness testimonies, is essentially absent, some are definitely known to be the work of human pranksters, and others can be adequately explained as such. There have been cases in which researchers declared crop circles to be "the real thing", only to be confronted with the people who created the circle and documented the fraud, like Bower and Chorley and tabloid Today hoaxing Pat Delgado, the Wessex Sceptics and Channel 4's Equinox hoaxing Terence Meaden, or a friend of a Canadian farmer hoaxing a field researcher of the Canadian Crop Circle Research Network. In his 1997 book The Demon-Haunted World: Science as a Candle in the Dark, Carl Sagan concludes that crop circles were created by Bower and Chorley and their copycats, and speculates that UFOlogists willingly ignore the evidence for hoaxing so they can keep believing in an extraterrestrial origin of the circles. Many others have demonstrated how complex crop circles can be created. Scientific American published an article by Matt Ridley, who started making crop circles in northern England in 1991. He wrote about how easy it is to develop techniques using simple tools that can easily fool later observers. He reported on "expert" sources such as The Wall Street Journal, who had been easily fooled and mused about why people want to believe supernatural explanations for phenomena that are not yet explained. Methods of creating a crop circle are now well documented on the Internet.
  Some crop formations are paid for by companies who use them as advertising. Many crop circles show human symbols, like the heart and arrow symbol of love, and stereotyped alien faces.
  Hoaxers have been caught in the process of making new circles, such as in 2004 in the Netherlands for example (see more cases in "legal implications" section above).
  Advocates of non-human causes discount on-site evidence of human involvement as attempts to discredit the phenomena. Some even argue a conspiracy theory, with governments planting evidence of hoaxing to muddle the origins of the circles. When Ridley wrote negative articles in newspapers, he was accused of spreading "government disinformation" and of working for the UK military intelligence service MI5. Ridley responded by noting that many cereologists make good livings from selling books and providing high-priced personal tours through crop fields, and he claimed that they have vested interests in rejecting what is by far the most likely explanation for the circles.
  In serious science magazines from the 1980s and 1990s, for example Science Illustrated, one could read reports on that the plants were bent by something that could be microwave radiation, rather than broken as they would become by physical impact. The magazines also contained serious reports of the absence of human influence and measurement of unusual radiation. Today, this is considered to be pseudoscience, while at the time it was sub
