The development of rules for scientific reasoning has not been straightforward; scientific method has been the subject of intense and recurring debate throughout the history of science, and eminent natural philosophers and scientists have argued for the primacy of ...
Use of the phrase "working hypothesis" goes back to at least the 1850s. [7]Charles Sanders Peirce came to hold that an explanatory hypothesis is not only justifiable as a tentative conclusion by its plausibility (by which he meant its naturalness and economy of explanation), [8] but also justifiable as a starting point by the broader promise that the hypothesis holds for research.
Typically, this entails a number of stages, including selecting a sample, gathering data from this sample, and evaluating this data. From assumptions made by researchers when undertaking a project, to the scales used, the research design, and data analysis, proper methodology in experimental psychology is made up of several critical stages.

Pure research is the source of most new scientific ideas and ways of thinking about the world. It can be exploratory, descriptive, or explanatory; however, explanatory research is the most ...
It reintroduces the basic assumptions of positivism: the possibility and desirability of objective truth, and the use of experimental methodology. The work of philosophers Nancy Cartwright and Ian Hacking are representative of these ideas. [citation needed] Postpositivism of this type is described in social science guides to research methods.

Especially important was the development of the "germ theory" of disease by European medical researchers such as Louis Pasteur and Robert Koch. During the late 19th and early 20th centuries, the physical causes of a variety ...
