ParapsychologyParapsychology is the study of mental phenomena, whether actual or purported, that are not currently explainable within the framework of mainstream, conventional science.
Interpretation of the EvidenceThe most hotly debated issue is the interpretation of the existing body of evidence that the field of parapsychology has gathered to date. At one extreme, some critics judge that the quality of the entire body of evidence to date is so poor that essentially the field has nothing to show for its entire history. At the other extreme, some believers in the paranormal believe that scientific study of paranormal phenomena, i.e. parapsychology, is redundant and completely unnecessary. In the spectrum of views in between, some consider that the existence of certain psi phenomena has now been well established by the scientific evidence; others consider that none of the evidence is anywhere near so definitive, though perhaps some of the evidence is intriguing enough to warrant further study. Criticisms of work in the field cover a wide range, from the general to the specific, for example:\n:* All anecdotal evidence, characteristic of so much of the early history of parapsychology and some areas of parapsychology today, is inherently unreliable. Anecdotes have natural explanations such as coincidence, fraud, imagination, or auto-suggestion.\n:* Psi phenomena are impossible, therefore a priori all psi experiments with positive results must be the result of fraud or incompetence.\n:* If a psi experiment is not 100% foolproof against fraud and has positive results, then it must be assumed that fraud was the cause of the positive results.\n:* Parapsychology experiments are poorly designed, such as lacking controls, allowing paths of intentional or unintentional information leakage through normal means, etc. Positive results are sure to decline and eventually disappear as experimental protocols improve.\n:* Parapsychology experiments are rarely replicated with positive results at independent laboratories.\n:* Positive results in psi experiments are so rare as to be negligible, i.e. indistinguishable from chance. For example, parapsychology may have a "file drawer" problem where a large percentage of negative results are never published, making positive results appear more significant than they actually are. \n:* Even unexplainable positive results of apparently sound experiments do not necessarily imply the existence of psi phenomena, i.e. normal explanations may yet be found.\n:* Psi phenomena cannot be accepted as explanation of positive results until there is a (widely) acceptable theory of how they operate. Responses from parapsychologists to some of these criticisms include:\n:* The hard evidence for psi phenomena today is founded on repeatable experiments and not anecdotal evidence.\n:* A priori judgements have no place in any science.\n:* There is no such thing as a 100% foolproof experiment in any field of science, and it is unreasonable to hold parapsychology to a higher standard of epistemology than the other sciences. Fraud and incompetence in parapsychology is addressed in the same way it is addressed in any other field of science: repeating experiments at multiple independent laboratories; publishing methods and results in order to receive critical feedback and design better protocols, etc.\n:* Experimental protocols have been continually improved over time, sometimes with the direct assistance of noted skeptics. Meta-analyses show that the significance of the positive results have not declined over time, but instead have remained fairly constant.\n:* There are certain phenomena which have been replicated with odds against chance far beyond that required for acceptance in any other science. Meta-analyses show that these cannot be accounted for by any file drawer problem.\n:* Anomalous phenomena do not disappear for lack of a theory. There are plenty of developments in the history of science where the anomalous phenomena came before the theory, and some common non-psi phenomena today still lack a satisfactory theory. Besides, there are many theories for aspects of psi phenomena, though not any one that is comprehensive and widely accepted within parapsychology.\n:* Anomalous phenomena cannot be dismissed until conventional science can provide explanations for them. The opinion of parapsychologists regarding the overall evaluation of the body of evidence to date is divided. As noted above, some parapsychologists are skeptics and do not believe that there is anything observed so far which cannot ultimately be explained by normal means. Probably a majority of parapsychologists believe in the likelihood, or at least the possibility, of actual psi phenomena, though there is a range of attitudes toward the evidence. Regarding the evidence, the rule of the thumb of the skeptical community is that extraordinary claims require extraordinary evidence. Since skeptics consider paranormal claims extraordinary, they think that the evidence needs to be better than what normally would be required. Most people use this approach to evidence in everyday life. For instance, if the news reports that the president of the USA has just arrived in South Korea for a state visit, most people will believe this at face value. The news is a fairly reliable source of information, and the president visiting a country such as South Korea is not an extraordinary claim. If the same newsbroadcast later mentions that a 92-year-old man has improved the world record time on the marathon by half an hour, any reasonable person would require more evidence, since the claim is extraordinary. Some parapsychologists agree with critics that the field has not yet reached the degree of consistent repeatability of experimental results needed for general consensus. John Beloff, for example, in his book Parapsychology: A Concise History, notes the evanescent -- some have said the apparently evasive -- nature of psychic phenomena over time, and that the range of phenomena observable in a given era seems to be culturally dependent. For example, in earlier times, psychic research studied macro physical phenomena demonstrated by spiritualist mediums which, according to the reports passed down to us in the literature, far surpassed anything that any of today's "psychics" can demonstrate. Skeptics consider this more evidence of the non-existence of psi phenomena. Yet many people, such as Beloff, cannot easily dismiss the entirety of all the positive accounts, so many of which came from the experts of their day (including scientists and conjurors), many of whom began as noted skeptics, and so believe that continued research in the field is justified. Other parapsychologists, such as Dean Radin and supporters such as statistician Jessica Utts, take the stance that the existence of certain psi phenomena has been reasonably well established in recent times through repeatable experiments that have been replicated dozens to hundreds of times at labs around the world. They refer to meta-analyses of psi experiments that conclude that the odds against chance (null hypothesis) of experimental results far exceeds that commonly required to establish results in other fields, sometimes by orders of magnitude. Indeed, many parapsychologists have moved on from proof-oriented research intended primarily to establish the existence of psi phenomena to "process-oriented" research intended to explore the parameters of psi phenomena. Time will tell whether these results prove to be evanescent as well.James Randi and The Randi ChallengeMagicianian James Randi demands that magicians as well as scientists be included as observers of psychic experiments, to help detect trickery. Professional magicians such as Randi have claimed that the feats performed by people who claim to be psychics can also be achieved by concealed and fraudulent physical manipulation; Randi, Penn & Teller, and other stage magicians often publicly perform such tricks in public, and then explain how they are done. Parapsychologists note that some parapsychologists are also magicians, and parapsychologists as a group already do in fact work with input from skeptics and fellow parapsychologists alike to continually improve their experimental protocols to continue to reduce the likelihood of fraud or unintentional error. Also, many modern parapsychologists do not study "people who claim to be psychics", so the feats of such claimants are largely irrelevant to their research. The James Randi Educational Foundation offers a one million U.S. dollars prize to anyone who can demonstrate any psychic or paranormal phenomenon. The foundation has set up a program wherein it approves the test proposed by the parapsychologist, but does not itself judge the results. No one has ever collected the prize. While skeptics make much of Randi's Challenge, many parapsychologists question the sincerity of Randi's offer, and in any case they generally pay little attention to it. The offering of prizes for demonstrations is not new to the field. Circa 1924, Scientific American magazine offered a $5000 prize to anyone who could produce any "visible psychic manifestation". Medium Mina Crandon, known in the literature as "Margery", made a bid and was tested by a committee set up by the editorial staff. Her performance was such that the committee members were split in their opinions. The magazine published the mixed report in its November 1924 issue, no prize was awarded, and the competition was declared closed the following year. In the early 1900s, the then well-known stage magician and skeptic Howard Thurston was sufficiently impressed by the demonstrations of medium Eusapia Palladino that he advertised in the New York Times his offer of $1000 to charity in the name of any fellow conjuror who could duplicate the feats of Ms. Palladino under similar conditions. He had no takers.Other Objections to ParapsychologyThere are a variety of other objections to parapsychology as well.
