Abstract

Three papers published by W. C. Levengood (1994), W. C. Levengood and N. P. Talbott (1999) and by E. H. Haselhoff (2001) suggested the involvement of some kind of electromagnetic radiation during the creation of crop circles. Here we discuss the methods and conclusions of the three articles, pointing out the misrepresentation of the experimental protocols, the misleading application of statistical procedures, the arbitrary discarding of unwanted results and the weakness of the proposed physical model to the suggested hypothesis. In particular, we show that Haselhoff's conclusions are unsubstantiated and do not prove the involvement of an electromagnetic radiation source in the creation event.
