Mörner has written a number of works claiming to provide theoretical support for dowsing, also known as water witching. [2] James Randi, the famous debunker of pseudo-science offered Mörner his $1,000,000 prize if he could successfully demonstrate water-witching which Mörner has advocated as scientific. As of early 2008 Mörner had not accepted The Amazing Randi's Challenge. Randi wrote in 1998
I've described here previously how a pompous-assed "dowsing expert" named Nils-Axel Mörner, associate professor of geology from Stockholm University, has consistently refused to be tested for the Pigasus Prize. [3]
