Understanding the scientific method is one of the first building blocks of teaching modern scientific research to students. But do experienced scientists concern themselves with what makes rigorous hypothesis formulation and testing? In the scientific journal of Natural History, author and scientist Neil de Grasse Tyson writes in his article "Belly Up to the Error Bar: The Scientific Method," about one of the most important parts of the scientific method in the 'real life' academic study and research of science, namely...

He calls experimental bias in favor of the initial hypothesis of the experimenter one of the greatest sources of blunders in research.
Although formal accounts of the scientific method typically describes a clinical "hypothesis-posing, experiment-conducting activity," in terms of "induction, deduction, cause, and effect," there is still a great deal of creativity and uncertainty in the formulation of said hypothesis. "Science can be a process in which practically anything goes -- from middle-of-the-night hunches to mathematical formulations driven by classical aesthetics" -- so long as the results eventually "accurately describe and predict phenomena in the real world." (Tyson, 1998, p.1)

Although formal accounts of the scientific method typically describes a clinical "hypothesis-posing, experiment-conducting activity," in terms of "induction, deduction, cause, and effect," there is still a great deal of creativity and uncertainty in the formulation of said hypothesis. "Science can be a process in which practically anything goes -- from middle-of-the-night hunches to mathematical formulations driven by classical aesthetics" -- so long as the results eventually "accurately describe and predict phenomena in the real world." (Tyson, 1998, p.1)

But in terms of bias in interpreting their results, scientists are only human. "When making multiple measurements, scientists occasionally discard values that deviate strongly from their expectations." (Tyson, 1998, p.1) In the social sciences, public opinion polls are accompanied by "margins of error." (Tyson, 1998, p.1) But in science experiments as well, "some measurements will come out above the true value, while some will come out below. These are ordinary fluctuations: a chart of all the data points would look like the statistician's beloved bell curve. The history of science has shown that if an experiment is well designed, then most of the data will cluster around some value, presumably the right one." (Tyson, 1998, p.1)

But the bias of the scientist in question in favor of his or her original hypothesis can also skew the perceptions of the final results.Does this mean that all scientfic finds according to the scientific method are potentially biased? Not necessarily, only that scientists are human beings, however objective the scientific method may seem. "In courts of law, yes/no questions and multiple-choice questions are common. But science does not lend itself to such responses without incurring major misrepresentations of reality," thus scientists must be particularly rigorous in their own self-scrutiny about their biases in favor of one hypothesis over another. (Tyson, 1998, p.2)

Scientific method is a procedure that was developed over centuries to organize the steps in the procedures of scientific investigations. These steps were designed so that the results gathered by scientists would be considered to be verifiable and repeatable, and therefore correct. By using the scientific method, scientists use observations and hypothesis, in order to predict the outcome of an experiment, then conduct that experiment and draw conclusions from the
