Multiple discovery
The concept of multiple discovery (also known as simultaneous invention)[self-published source] is the hypothesis that most scientific discoveries and inventions are made independently and more or less simultaneously by multiple scientists and inventors.[page needed] The concept of multiple discovery opposes a traditional view—the "heroic theory" of invention and discovery.[not verified in body] Multiple discovery is analogous to convergent evolution in biological evolution.[according to whom?][clarification needed]
When Nobel laureates are announced annually—especially in physics, chemistry, physiology, medicine, and economics—increasingly, in the given field, rather than just a single laureate, there are two, or the maximally permissible three, who often have independently made the same discovery.[according to whom?][citation needed] Historians and sociologists have remarked the occurrence, in science, of "multiple independent discovery". Robert K. Merton defined such "multiples" as instances in which similar discoveries are made by scientists working independently of each other. Merton contrasted a "multiple" with a "singleton"—a discovery that has been made uniquely by a single scientist or group of scientists working together. As Merton said, "Sometimes the discoveries are simultaneous or almost so; sometimes a scientist will make a new discovery which, unknown to him, somebody else has made years before."[page needed]
Commonly cited examples of multiple independent discovery are the 17th-century independent formulation of calculus by Isaac Newton, Gottfried Wilhelm Leibniz and others;[page needed] the 18th-century discovery of oxygen by Carl Wilhelm Scheele, Joseph Priestley, Antoine Lavoisier and others;[citation needed] and the theory of evolution of species, independently advanced in the 19th century by Charles Darwin and Alfred Russel Wallace.[better source needed][better source needed] What holds for discoveries, also goes for inventions.[according to whom?][citation needed] Examples are the blast furnace (invented independently in China, Europe and Africa),[citation needed] the crossbow (invented independently in China, Greece, Africa, northern Canada, and the Baltic countries),[citation needed] magnetism (discovered independently in Greece, China, and India),[citation needed] the computer mouse (both rolling and optical), powered flight, and the telephone.
Multiple independent discovery, however, is not limited to only a few historic instances involving giants of scientific research. Merton believed that it is multiple discoveries, rather than unique ones, that represent the common pattern in science.
Multiple discoveries in the history of science provide evidence for evolutionary models of science and technology, such as memetics (the study of self-replicating units of culture), evolutionary epistemology (which applies the concepts of biological evolution to study of the growth of human knowledge), and cultural selection theory (which studies sociological and cultural evolution in a Darwinian manner).[citation needed]
Multiple independent discovery and invention, like discovery and invention generally, have been fostered by the evolution of means of communication: roads, vehicles, sailing vessels, writing, printing, institutions of education, reliable postal services, telegraphy, and mass media, including the internet.[according to whom?][citation needed] Gutenberg's invention of printing (which itself involved a number of discrete inventions) substantially facilitated the transition from the Middle Ages to modern times.[citation needed] All these communication developments have catalyzed and accelerated the process of recombinant conceptualization,[clarification needed] and thus also of multiple independent discovery.[citation needed]
Multiple independent discoveries show an increased incidence beginning in the 17th century. This may accord with the thesis of British philosopher A.C. Grayling that the 17th century was crucial in the creation of the modern world view, freed from the shackles of religion, the occult, and uncritical faith in the authority of Aristotle. Grayling speculates that Europe's Thirty Years' War (1618–1648), with the concomitant breakdown of authority, made freedom of thought and open debate possible, so that "modern science... rests on the heads of millions of dead." He also notes "the importance of the development of a reliable postal service... in enabling savants... to be in scholarly communication.... [T]he cooperative approach, first recommended by Francis Bacon, was essential to making science open to peer review and public verification, and not just a matter of the lone [individual] issuing... idiosyncratic pronouncements."
The paradigm of recombinant conceptualization (see above)—more broadly, of recombinant occurrences—that explains multiple discovery in science and the arts, also elucidates the phenomenon of historic recurrence, wherein similar events are noted in the histories of countries widely separated in time and geography. It is the recurrence of patterns that lends a degree of prognostic power—and, thus, additional scientific validity—to the findings of history.[page needed]
