Parapsychology

Parapsychology is the study of the evidence involving phenomena where a person seems to affect or to gain information about something through a means not currently explainable within the framework of mainstream, conventional science. Proponents of the existence of these phenomena usually consider them to be a product of unexplained mental abilities.

Responses from parapsychologists to criticisms

• The hard evidence for psi phenomena today is founded on repeatable experiments and not anecdotal evidence.
• Anecdotal evidence is considered valid in law and many other fields. The validity of anecdotal evidence does not depend upon the opinion of those listening to it.
• There is no such thing as a completely 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.
• 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.
• 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.
• Anomalous phenomena do not disappear for lack of a theory. There have been many instances in the history of science where the observation of an anomalous phenomenon came before an explanatory theory, and some commonly accepted non-psi phenomena today still lack a perfectly satisfactory, undisputed theory. For instance, in the past, those who sighted meteors falling to the earth were dismissed as madmen or false prophets.
• Theories abound in parapsychology for aspects of psi phenomena, though there is not any one that is comprehensive and widely accepted within parapsychology.
• It is not necessary to be a licensed psychiatrist or acquainted with clinical psychology to test the validity of psi. The field of parapsychology overlaps many disciplines, including physics and biology, and often physicists, engineers and others trained in the hard sciences, in conjunction with stage magicians and other experts in deception, are in a better position to design experiments for certain types of phenomena than are psychiatrists or psychologists.

The opinion of parapsychologists regarding the overall evaluation of the body of evidence to date is divided. As noted above, some parapsychologists are skeptic and do not believe that there is anything observed so far which cannot ultimately be explained within the existing framework of known science. 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 may consider paranormal claims extraordinary, they may think that the evidence needs to be better than what normally would be required. However, this puts the responsibility for investigating seemingly paranormal phenomena squarely on the shoulders of proponents and "internal" skeptics. Not only is research conducted by "external" critics and skeptics useful to the field as a whole, but it also imparts a kind of craft knowledge to critics and skeptics that makes their criticism and counter-hypotheses more productive and more useful. Further many of the counter-hypotheses proposed by skeptics are so unparsimonious as to be extraordinary claims as well, and in that case, those counter-hypothesis, also require extraordinary evidence. Sadly, given the Zeitgeist in science today which treats even the study of seemingly paranormal phenomena as taboo, the extraordinary/unparsimonious claims of the skeptics are accepted uncritically, without investigation. See an article by the late sociologist and skeptic Marcello Truzzi which is relevant to this topic http://www.skepticalinvestigations.org/anomalistics/practices.htm.

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 take this at face value. The news is considered a fairly reliable source of information, and the president visiting a country such as South Korea is not an extraordinary claim. However, if the same news broadcast later mentioned that a 92-year-old man has improved the world record time on the marathon by half an hour, many reasonable people would require more evidence, even despite the assumed reliability of the source, since the claim is extraordinary. This analogy might be flawed however. In the case of the 92 year old man we have positive evidence gained from a lifetimes experience and the reassurance of physiologists that this feat is indeed extraordinary (i.e improbable). When it comes to parapyschology however, some would argue we have no positive evidence that it is imporbable, only our own cultural bias and a subjective sense that Psionic powers are extraordniary. hence, some would argue, it is not the sort of extraordinary claim which nessecairly need's more evidence then a mundane claim.

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, 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 physical phenomena demonstrated by spiritualist mediums that, 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. Frequently this particular claim is the result of the proponent community having cut itself off, because of political pressures of conforming to the scientific Zeitgeist, from the community of modern mediums and psychics who operate today. Whether or not the phenomena being exhibited by modern day mediums can provide proof of traditional notions of spirituality or can be attributed to the operation of mundane psychological processes is mostly an open question, due to the lack of research. So it is possible that physical phenomena is being exhibited today, but to what cause the effects may be attributed is an open question, even among parapsychologists.

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 conjurers), 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 verify the existence of psi phenomena, to "process-oriented" research, intended to explore the parameters and characteristics of psi phenomena. Time will tell whether these results prove to be evanescent as well. Unfortunately what complicates the "time will tell" hope that many skeptics and proponents have is the lack of funds available for research from either the conventional or the "paranormalist" perspectives, and the negative impact on career advancement that an interest in these phenomena -- even from a skeptical point of view -- can have.
