Is psychokinesis constructive?
Telepathy, clairvoyance, and psychokinesis (Parapsychology, n.d.). The Parapsychological Association describes parapsychology as "the scientific study of paranormal or ostensibly paranormal phenomena, that is, psi; except in Britain, the term has largely superseded the older expression 'psychical research;' used by some to refer to the experimental approach to the field".
Proponents style parapsychology as a discipline compatible with science and other schools of psychology, however those assertions and the results of parapsychological work have met with frequent opposition from critics. Historically, however, psychical research has attracted notable personalities in psychology, such as American psychologist and philosopher William James, among others.
Many scientists feel that parapsychological study is at best on the outer edges of science because it involves research that doesn't fit within standard theoretical models accepted by mainstream science. A large portion of parapsychological work involves examining the statistical evidence for psi, a generic term described by parapsychologists as indicating anomalies that may be attributed to paranormal phenomena. Although, in general, the methods used are considered scientific, an article published in the February 2007 issue of Nature characterized the "decision whether to pursue a tiny apparent effect or put it down to statistical flaws [as] a subjective one". The controversy over parapsychological study is an example of the larger debate over the demarcation problem in science, which examines the boundaries commonly drawn between science and non-science. To date there have been no experimental results that have gained wide acceptance in the scientific community as valid evidence of paranormal phenomena.
Are psi phenomena really "impossible" according to contemporary science? As Robert Jahn's experience with the Nobel laureates revealed, the answer will depend upon whom you ask. ... Fortunately the march of scientific progress is usually only temporary slowed down by people saying "impossible." For a long time meteorites were declared "impossible." The idea that continents could drift around the surface of the earth was ridiculed for decades. The history of science is full of other "impossibilities" that have become ordinary parts of everyday life. A number of leading physicists, acknowledged giants of the field, such as Henry Margenau, David Bohm, and O. Costa de Beauregard have repeatedly claimed that there is nothing in quantum physics that forbids psi phenomena. ... Nobel laureate Brian Josephson, a strong supporter of parapsychology, has stated that some of the most convincing evidence he has seen for the existence of psi phenomena comes not from the diligent work of the parapsychologists but from experiments in quantum physics. So science does not speak with one voice on the matter of parapsychology. Such is life on the frontiers of knowledge. All we can say now is that the jury is still out.
