Comments on Marcello Truzzi's Paper

M. Truzzi's article (see SA 26:5/J6468) is critically reviewed. Although it is true that skepticism can be exaggerated, it is misleading to believe that the premise that fraud exists without any evidence for it is a claim that stands outside the realm of science. A book by C. E. M. Hansel (1966) dealing with a scientific evaluation of ESP reveals that author to be a skeptic who claims fraud exists without any evidence of it. His skepticism is here analyzed, & is shown to uphold the reasonable "burden-of-proof principle." Also, Hansel uncovered defects in the ESP experiments, revealing that the fraud without evidence claim has a place in science. G. Simpson.
