=== Overview ===
There are different ways of outlining the basic method used for scientific inquiry and they are better considered as general principles than a fixed sequence of steps.{{sfnp|Gauch|2003|p=3}} The [[scientific community]] and [[philosophers of science]] generally agree on the following classification of method components. These methodological elements and organization of procedures tend to be more characteristic of [[experimental science]]s than [[social science]]s. Nonetheless, the cycle of formulating hypotheses, testing and analyzing the results, and formulating new hypotheses, will resemble the cycle described below.{{anchor|epistemicCycle|Process}} The scientific method is an iterative, cyclical process through which information is continually revised.{{efn-lg|name=unifiedMethod|1= The topics of study, as expressed in the vocabulary of its scientists, are approached by a "single unified method".<ref name= cowles />{{rp|pp.8,13,33–35,60}} A topic is [[Unification of theories in physics|unified]] by its [[Predicate variable|predicate]]s, which describe a [[system]] of mathematical [[Expression (mathematics)|expression]]s.<ref name=Knight1989 >Kevin Knight (1989) [https://kevincrawfordknight.github.io/papers/unification-knight.pdf Unification: A Multidisciplinary Survey] ACM Computing Surveys, Vol. 21, No. 1, March 1989 </ref>{{rp|93-94,113-117}} The values which a [[Predicate (mathematical logic)|predicate]] might take, then serve as [[Witness (mathematics)|witness]] to the validity of a predicated expression (that is, ''true'' or ''false''; 'predicted but not yet observed'; 'corroborates', etc.).}}<ref>{{cite book |last1=Godfrey-Smith |first1=Peter |url=https://books.google.com/books?id=k23egtSWrb8C |title=Theory and Reality: An Introduction to the Philosophy of Science |date=2009 |publisher=University of Chicago Press |isbn=978-0-226-30062-7 |location=Chicago |author-link=Peter Godfrey-Smith |access-date=2020-05-09 |archive-url=https://web.archive.org/web/20231129112726/https://books.google.com/books?id=k23egtSWrb8C |archive-date=2023-11-29 |url-status=live}}</ref><ref name="Brody-1993">{{harvp|Brody|1993|p=10}} calls this an ''[[#epistemicCycle|epistemic cycle]]''; these cycles can occur at high levels of abstraction.</ref> It is generally recognized to develop advances in knowledge through the following elements, in varying combinations or contributions:<ref name="Fixation">{{cite wikisource|title=The Fixation of Belief|first=Charles Sanders|last=Peirce|year=1877|wslink=The Fixation of Belief|volume=12|pages=1–15|journal=Popular Science Monthly}}.</ref><ref name="Vital">Peirce, Charles S., ''Collected Papers'' v. 5, in paragraph 582, from 1898: "...&nbsp;[rational] inquiry of every type, fully carried out, has the vital power of self-correction and of growth.

While this schema outlines a typical hypothesis/testing method,{{sfnp|Gauch|2003|loc=esp. chapters 5–8}} many philosophers, historians, and sociologists of science, including [[Paul Feyerabend]],{{efn|name= descartes| "no opinion, however absurd and incredible, can be imagined, which has not been maintained by some of the philosophers". —Descartes<ref name= discourseOnMethod >[[René Descartes]] (1637) [https://en.wikisource.org/wiki/Discourse_on_the_Method/Part_2 Discourse on the Method/Part 2] {{Webarchive|url=https://web.archive.org/web/20210901150801/https://en.wikisource.org/wiki/Discourse_on_the_Method/Part_2 |date=2021-09-01 }} Part II</ref> }} claim that such descriptions of scientific method have little relation to the ways that science is actually practiced.
