Parsimony may be used to estimate "species" or "gene" phylogenies. Parsimony, or the "principle of parsimony", is a method for selecting between equally valid hypotheses based on the complexity of each. Background: The word "parsimonious" comes from the Latin word "parsimoniae." While there are currently no definitive criteria for determining the parsimony of qualitative research findings, it would be epistemologically inappropriate and philosophically incongruent to import and translate quantitative notions of parsimony. Occam's razor, Ockham's razor, Ocham's razor (Latin: novacula Occami), or law of parsimony (Latin: lex parsimoniae) is the problem-solving principle that "entities should not be multiplied without necessity", or more simply, the simplest explanation is usually the right one. Multiple criteria for good research . Science [edit | edit source]. Since Aristotle introduced logic and JMIR Public Health Surveill.

Parsimony analysis is the second primary way to estimate phylogenetic trees from aligned sequences. A parsimonious theory is a theory that is simpler than other competing theories because it introduces the least new assumptions about the subject in question. Generally, frugality or thriftiness. Adoption of the simplest assumption in the formulation of a theory or in the interpretation of data, especially in accordance with the rule of Ockham's razor. An introduction to qualitative research concepts for nurses. ; van de Bunt, G.G. In the analysis of phylogeny, parsimony means that a hypothesis of relationships that requires the smallest number of character changes is most likely to be correct.In molecular systematics, these character changes are DNA mutations. In science, parsimony is preference for the least complex explanation for an observation. Sign into your Profile to find your Reading Lists and Saved Searches. The application of parsimony or Ockham’s (or Occam’s) razor is critically important to theory development as it advocates for simplicity over complexity and necessity over the superfluous to explain a given phenomenon.

It is the hope of the authors that this paper might raise awareness of the hitherto unexplored issues, stimulate some further interest in these and prompt other qualitative researchers to contribute to the ensuing debate. In phylogenetics, for example, the preferred tree showing evolutionary relationships between species, molecules, or other entities is the one that requires the least amount of evolutionary change, that is, maximum parsimony. Learn more. The principle of parsimony reflects the notion that researchers should strive for simple measurement models that use the minimum number of parameters needed to explain a given phenomenon (Raykov & Marcoulides, 1999). In fields like science and logic, one way you might see the word parsimony applied is in the Principle of Parsimony.Related to Occam's razor, the Principle of Parsimony is an approach to problem solving that states that, when confronted with a question or investigation, the simplest (and therefore most cautious) explanation should be assumed.

Clipboard, Search History, and several other advanced features are temporarily unavailable. Parsimonious modeling is particularly important for the development of integrated theoretical frameworks. Another way to say this is that the correct explanation or solution is usually the simplest. In a 2010 research review, researchers used the law of parsimony to create a less complicated way to think of the negative symptoms of schizophrenia. One of the principles of reasoning used in science as well as philosophy is the principle of parsimony or Occam’s razor. Parsimony has a practical value in science but has little support for its epistemic value (Sober 2015), especially when complexity is expected in natural systems. Int J Nurs Stud.
