Science and Common Sense. Pages Empirical Foundations. Empirical Testing. To meet this difficulty, Darwin developed a new scientific procedure, now known as the hypothetico-deductive method.

He first developed a theory, relying upon analogy and deduction to organize a plausible explanation, without direct empirical evidence, and then applied that theory to a wide range of facts, to demonstrate the explanatory power of what he was proposing. Johnston reminds us that the scientific method has evolved over a period of time and that the lengthy gap between Darwin's Beagle trip and the publication of the Origin of Species had to do with the limitations in the methodology of doing science at that time.

Michael James has provided an interesting essay on the history of the scientific method; the essay is a frequent hit on many search engines Figure 9. James is a graduate student in the human geography department at the Open University in England. Science classifies by definite rules. The appearance that the use of scientific method is simply logical can be misleading, there is no more complex question of how we arrive at our thoughts.

The now ubiquitous Wikipedia, the Internet encyclopedia, provides a number of portals into the history of the scientific method Figure Francis Bacon, a contemporary of Shakespeare, developed a method of scientific reasoning and investigation that was widely adhered to for several centuries.

Johnston above alludes to Darwin having to deal with the Baconian method. Karl Popper developed the hypothetico-deductive method in the twentieth century and its practice involves falsification of the hypothesis. It is the falsification idea that contributes greatly to today's misunderstanding of what science is, and how the modern version of the scientific method is used.

The issue of falsification is also where the Kansas Board of Education enters Dante's Divine Comedy and descends into the inferno. How many science teachers or scientists know of the Vienna Circle of science philosophers of the s? These individuals developed a view of analytical philosophy including logical positivism.

Karl Popper led the revolt against logical positivism set forth by the Vienna Circle. How many understand the idea of confirmation holism where a falsification of hypothesis can be undone? Who among the proponents and detractors of evolutionary theory have read Lakatos and Feyerabend's modification of Popperian ideas? The scientific method has evolved.

The scientific method also has critics. One place that records criticism is the Web site known as the Science Hobbyist. William J. The notion that a common series of steps is followed by all research scientists must be among the most pervasive myths of science given the appearance of such a list in the introductory chapters of many precollege science texts.

This myth has been part of the folklore of school science ever since its proposal by statistician Karl Pearson The steps listed for the scientific method vary from text to text but usually include, a define the problem, b gather background information, c form a hypothesis, d make observations, e test the hypothesis, and f draw conclusions.

Some texts conclude their list of the steps of the scientific method by listing communication of results as the final ingredient. One of the reasons for the widespread belief in a general scientific method may be the way in which results are presented for publication in research journals.

The standardized style makes it seem that scientists follow a standard research plan. Medawar reacted to the common style exhibited by research papers by calling the scientific paper a fraud since the final journal report rarely outlines the actual way in which the problem was investigated. The notion of a single scientific method is so pervasive it seems certain that many students must be disappointed when they discover that scientists do not have a framed copy of the steps of the scientific method posted high above each laboratory workbench.

Close inspection will reveal that scientists approach and solve problems with imagination, creativity, prior knowledge and perseverance. These, of course, are the same methods used by all problem-solvers. The lesson to be learned is that science is no different from other human endeavors when puzzles are investigated.

An unusual place to find a discourse on the scientific method is Dharma-Haven, a site that deals with Tibetan medicine and western science. One of them deals with the myth of the scientific method Figure Studying what scientists actually do is far more interesting. Another critique of the scientific method may be found at the University of New South Wales. John A. Schuster's Chapter 9 is delightful and needs to be read in its entirety. The following two excerpts give the flavor of his arguments:.

Method is a great story which has a wonderful history of at least years back to Aristotle, who invented the commonly accepted method story. In the 17th century we have people like Francis Bacon, Galileo, Newton who updated and approved that story.

The story of method has a real function in science which unfortunately is not to tell us how science is done. In fact, its job is to mislead us as to how science is done. Method operates like a cultural myth, protecting science and scientists because it allows them to say to nonscientists why they scientists are special and why they should be left alone. The myth states that there is a way of doing things in science which people outside of science do not know or cannot properly use And so, in this century, even though this story has been criticized, there are philosophers and other people who still want to tell us that the scientific method exists.

They believe a different version of the scientific method can be designed that is viable, one that at long last is the correct version.
