"In science, the burden of proof falls upon the claimant; and the more extraordinary a claim, the heavier is the burden of proof demanded. The true skeptic takes an agnostic position, one that says the claim is not proved rather than disproved. He asserts that the claimant has not borne the burden of proof and that science must continue to build its cognitive map of reality without incorporating the extraordinary claim as a new "fact." Since the true skeptic does not assert a claim, he has no burden to prove anything. He just goes on using the established theories of "conventional science" as usual. But if a critic asserts that there is evidence for disproof, that he has a negative hypothesis—saying, for instance, that a seeming psi result was actually due to an artifact—he is making a claim and therefore also has to bear a burden of proof. "

Marcello Truzzi was an interesting character. He was born in 1935 in Copenhagen, in a Russian family of circus performers. The family moved to the US in the 1940, and Marcello became professor of sociology at Eastern Michigan University. He is one of the founders of the Society for Scientific Exploration (http://www.scientificexploration.org/), which aims at "the rigorous study of unusual phenomena that may be ignored or inadequately studied within mainstream science". He died in 2003.
