<a HREF="http://www.almaz.com/nobel/chemistry/1932a.html">Nobel-laureate</a> in chemistry <img src="graphics/langmuir.jpg" alt="Irving Langmuir" width="278" height="208" class="floatRight" /><a href="http://nobelprize.org/chemistry/laureates/1932/langmuir-bio.html">Irving Langmuir</a> in a presentation he made at General Electric's Knolls Atomic Power Laboratory a few years before his death in 1957. Langmuir described typical cases as involving such things as barely detectable causal agents observed near the threshold of sensation which are nevertheless asserted to have been detected with great accuracy. The supporters offer fantastic theories that are contrary to experience and meet criticisms with <a href="adhoc.html">ad hoc excuses</a>. And, most telling, only supporters can reproduce the results. Critics can't duplicate the experiments. </font> </p> <p style="text-align: left"><font face="Arial" size="3">He gave several examples, including <a href="esp.html">ESP</a> experiments and  <a HREF="blondlot.html">Blondlot's N-rays</a>, and stated that </font> </p> <blockquote> <p><font face="Arial" size="3">These are cases where there is no dishonesty involved but where people are tricked into false results by a lack of understanding about what human beings can do to themselves in the way of being led astray by subjective effects, wishful thinking or threshold interactions. These are examples of pathological science. These are things that attracted a great deal of attention. Usually hundreds of papers have been published on them. Sometimes they have lasted for 15 or 20 years and then gradually have died away. </font> </p> </blockquote> <p style="text-align: left"><font face="Arial" size="3">Langumuir visited J.B. Rhine's lab at Duke University where Rhine was claiming results of ESP experiments that could not be predicted by chance and were probably due to some sort of psychic power. Langmuir found that Rhine was not counting all his data, however. He was leaving out the scores of those he believed were guessing their<a href="zener.html"> Zener cards </a>wrong on purpose. "Rhine believed that persons who disliked him guessed wrong to spite him. Therefore, he felt it would be misleading to include their scores" (Park 2000, 42). Rhine determined that some of his subjects were deliberately guessing wrong because their scores were too low to have occurred by chance. "Indeed, he was convinced that abnormally low scores were as significant as abnormally high scores in proving the existence of ESP" (ibid.). </font> </p> <p style="text-align: left"><a name="update" id="update"></a>[<span class="highlight">new</span>] Langmuir also deemed pathological science the work of Russian embryologist <a href="https://en.wikipedia.org/wiki/Alexander_Gurwitsch">Alexander Gurwitsch</a> who claimed that <a href="https://en.wikipedia.org/wiki/Biophoton">biophotons</a> (very weak photon emissions in the ultraviolet range from living tissue), which Gurwitch called "mitogenetic rays," stimulated cell division. There had been claims during the Stalin regime that biophotons were used to diagnose cancer. There has never been a replication of these findings, if indeed they were findings.[/<span class="highlight">new</span>]</p> <p style="text-align: left">In the 1920s, thereported "ultraweak" photon emissions from living tissues in the UV-range of the spectrum. He named them because his experiments convinced him that they had a stimulating effect on cell division. Biophotons were claimed to have been employed by the Stalin regime to diagnose cancer. The method has not been tested in the West. However, failure to replicate his findings and the fact that, though cell growth can be stimulated and directed by radiation this is possible only at much higher amplitudes, evoked a general skepticism about Gurwitsch's work. In 1953 Irving Langmuir dubbed Gurwitsch's ideas pathological science. Commercial products, therapeutic claims and services supposedly based on his work appear at present to be best regarded as such.</p> <p style="text-align: left"><font face="Arial" size="3">A. Cromer, commenting on Langmuir's characteristics of pathological science, noted that scientists are often not very good judges of the scientific process. Even the best intentions can be subverted by <a href="selfdeception.html"> self-deception.</a> Good science is not simply a matter of honesty or wisdom. Furthermore, </font> </p> <blockquote> <p><font face="Arial" size="3">Real discoveries of phenomena contrary to all previous scientific experience are very rare, while fraud, fakery, foolishness, and error resulting from overenthusiasm and delusion are all too common (Cromer 1993).</font></p> </blockquote> <p style="text-align: left"><font face="Arial" size="3">Do Langmuir's observations imply that scientists should shy away from controversial topics such as prions, <a href="facilcom.html">facilitated communication</a>, cold fusion, <a href="orgone.html">orgone energy</a>, ESP, and zero-point energy? No. What follows is that <i>any </i>scientist doing <i>any </i>research must proceed with caution, tentativeness, a sense of the history of science and an awareness of the tendencies in human nature which can easily lead the wisest of men or women astray. What also seems to follow is that to show little or no interest in allowing oneself and others to try to prove one's fantastic theories to be wrong, while immediately meeting every objection with <a href="adhoc.html">ad hoc hypotheses</a>, is a sign of pathological science if not <a HREF="pseudosc.html">pseudoscience</a>. </font> </p> <p style="text-align: left"><font face="Arial" size="3"><b>See also</b> <a HREF="adhoc.html">ad hoc hypothesis</a>, <a HREF="blondlot.html">Blondlot and N-rays</a>, <a HREF="communalreinforcement.html">communal reinforcement,</a> <a href="confirmbias.html">confirmation bias</a>,  <a href="control.html">control study,</a> <a href="occam.html">Occam's razor,</a> <a HREF="placebo.html">placebo effect</a>, <a href="posthoc.html">post hoc fallacy</a>, <a HREF="selectiv.html">selective thinking</a>, <a href="science.html">science</a><strong>,</strong> <a href="subjectivevalidation.html">subjective validation</a>,<a href="testimon.html"> testimonial evidence</a>,  and <a href="wishfulthinking.html">wishful thinking.</a>. </font> </p> <hr noshade width="25%" align="left"> <p style="text-align: left"><font face="Arial" size="3"><b>further reading</b> </font> </p> <p style="text-align: left"><strong><font face="Arial" size="3">books and articles</font></strong></p> <p style="text-align: left"><font face="Arial" size="3">Cromer, A., "Pathological Science: An Update," <i>Skeptical Inquirer</i>, SUMMER 1993 (vol 17, no. 4). </font> </p> <p style="text-align: left"><font face="Arial" size="3">Langmuir, Irving (transcribed and ed., Robert N.
