Constructive criticism is essential in science and is welcomed by the majority of active psi researchers. Strong skepticism is expected, and many parapsychologists are far more skeptical about psi than most scientists realize.
However, it is not generally appreciated that some of the more vocal criticisms about psi are actually “pseudo-criticisms.” That is, the more barbed, belligerent criticisms occasionally asserted by some skeptics are often issued from such strongly held, prejudicial positions that the criticisms are not offered as constructive suggestions, but as authoritarian proofs of the impossibility of psi.
It is commonly supposed by non-scientists that skeptical debates over the merits of psi research follow the standards of scholarly discussions. Unfortunately, this is not always the case. Disparaging rhetoric and ad hominem attacks arise too often in debates about psi. The social science of parapsychology, and the way that science treats anomalies in general, is a fascinating topic that starkly illuminates the very human side of how science really works.
