Thurs October 28, The so-called scientific method is a myth. But to squeeze a diverse set of practices that span cultural anthropology, paleobotany, and theoretical physics into a handful of steps is an inevitable distortion and, to be blunt, displays a serious poverty of imagination.
If typical formulations were accurate, the only location true science would be taking place in would be grade-school classrooms. Scratch the surface of the scientific method and the messiness spills out.
Even simplistic versions vary from three steps to eleven. Some start with hypothesis, others with observation.
Others confine themselves to facts. Question a simple linear recipe and the real fun begins. To make matters worse, arrows point every which way. Mouse over each circle and you find another flowchart with multiple categories and a tangle of additional arrows.
A broadly conceived method receives virtually no attention in scientific papers or specialized postsecondary scientific training. Meanwhile, the notion of a heavily abstracted scientific method has pulled public discussion of science into its orbit, like a rhetorical black hole.
Educators, scientists, advertisers, popularizers, and journalists have all appealed to it. Its invocation has become routine in debates about topics that draw lay attention, from global warming to intelligent design. Standard formulations of the scientific method are important only insofar as nonscientists believe in them.
The Bright Side Now for the good news. The scientific method is nothing but a piece of rhetoric. Granted, that may not appear to be good news at first, but it actually is.
The scientific method as rhetoric is far more complex, interesting, and revealing than it is as a direct reflection of the ways scientists work. At the same time, scratch their surface, and their meanings become full of messiness, variation, and contradiction. Scientific method is a keyword or phrase that has helped generations of people make sense of what science was, even if there was no clear agreement about its precise meaning— especially if there was no clear agreement about its precise meaning.
The term could roll off the tongue and be met by heads nodding in knowing assent, and yet there could be a different conception within each mind. As long as no one asked too many questions, the flexibility of the term could be a force of cohesion and a tool for inspiring action among groups.
A word with too exact a definition is brittle; its use will be limited to specific circumstances. A word too loosely defined will create confusion and appear to say nothing. A word balanced just so between precision and vagueness can change the world. The Scientific Method, a Historical Perspective This has been true of the scientific method for some time.
Methodological pictures painted by practicing scientists have often been tailored to support their own position and undercut that of their adversaries, even if inconsistency results. As rhetoric, the scientific method has performed at least three functions: It has typically fulfilled all these roles at once, but they also represent a rough chronology of its use.
Later, it was used more forcefully to show nonscientists how science could be made relevant. More or less coincidentally, its invocation assuaged any doubts that real science was present.
Timing is a crucial factor in understanding the scientific method.
Discussion of the best methodology with which to approach the study of nature goes back to the ancient Greeks. Method also appeared as an important concern for natural philosophers during the Islamic and European Middle Ages, whereas many historians have seen the methodological shifts associated with the Scientific Revolution as crucial to the creation of modern science.
In short, the scientific method is a relatively recent invention. Periodicals Content Index But it was not alone. All of this paralleled a shift in popular notions of science from general systematized knowledge during the early s to a special and unique sort of information by the early s.Lab #1: Investigating the Scientific Method Objectives: 1) To practice the scientific method by making observations, selecting a question, constructing a hypothesis, and collecting and analyzing data.
