Bit of a... BOLD insertion of a new section at the very top of the article, but I feel it has merit. Credit to Ancheta Wis for passing down The Tetrast's work with Pierce's Musement. Tag: Reverted |
Undid revision 1218544333 by JackTheSecond (talk) friendly revert of very bold editing. there is clearly no consensus for this radical change, and it would definitely need discussion first. there is no one canonical method, statistics is not essential to science, empiricism is diffierent from empirical science, etc. |

The ubiquitous element in the scientific method is [[empiricism]]. This is in opposition to stringent forms of [[rationalism]]: the scientific method embodies the position that ''reason alone'' cannot solve a particular scientific problem. A strong formulation of scientific method is not always aligned with a form of [[empiricism]] in which the empirical data is put forward in the form of experience or other abstracted forms of knowledge; in [[#aModel|current scientific practice]], however, the use of [[scientific modelling]] and reliance on abstract typologies and theories is normally accepted. The scientific method counters claims that [[revelation]], political or religious [[dogma]], appeals to tradition, commonly held beliefs, common sense, or currently held theories pose the only possible means of demonstrating truth.<ref name= truthSought4sake /><ref name="reasonsFirstRule">{{cite book |last=Peirce |first=Charles S. |title=Collected Papers |year=1899 |series=v. 1 |at=paragraphs 135–140 |chapter=F.R.L.

}}{{efn|name= Kepler1604| Kepler was driven to this experiment after observing the partial solar eclipse at Graz, July 10, 1600. He used Tycho Brahe's method of observation, which was to project the image of the Sun on a piece of paper through a pinhole aperture, instead of looking directly at the Sun. He disagreed with Brahe's conclusion that total eclipses of the Sun were impossible because there were historical accounts of total eclipses. Instead, he deduced that the size of the aperture controls the sharpness of the projected image (the larger the aperture, the more accurate the image – this fact is now fundamental for optical system design). {{harvp|Voelkel|2001|p=61}}, notes that Kepler's 1604 experiments produced the first correct account of vision and the eye, because he realized he could not accurately write about astronomical observation by ignoring the eye. {{harvp|Smith|2004|p=192}} recounts how Kepler used Giambattista della Porta's water-filled glass spheres to model the eye, and using an aperture to represent the entrance pupil of the eye, showed that the entire scene at the entrance pupil-focused on a single point of the rear of the glass sphere (representing the retina of the eye).

The early version of the canonical "sequence" of elements was first formulated in the 19th century. A sea voyage from America to Europe afforded [[C. S. Peirce]] the distance to clarify his ideas, gradually resulting in the [[hypothetico-deductive model]].{{sfnp|Godfrey-Smith|2003|p=236}} Formulated in the 20th century, the model has undergone significant revision since first proposed.

▲=== 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: "...

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.

Most experimental results do not produce large changes in human understanding; improvements in theoretical scientific understanding typically result from a gradual process of development over time, sometimes across different domains of science.<ref>Stanovich, Keith E. (2007). ''How to Think Straight About Psychology''. Boston: Pearson Education. p. 123</ref> Scientific models vary in the extent to which they have been experimentally tested and for how long, and in their acceptance in the scientific community. In general, explanations become accepted over time as evidence accumulates on a given topic, and the explanation in question proves more powerful than its alternatives at explaining the evidence. Often subsequent researchers re-formulate the explanations over time, or combined explanations to produce new explanations.

[[Paul Feyerabend]] examined the history of science, and was led to deny that science is genuinely a methodological process. In his book ''[[Against Method]]'' he argued that no description of scientific method [[#critiquesOfFeyerabend|could possibly be broad enough]] to include all the approaches and methods used by scientists, and that there are no useful and exception-free [[methodology|methodological rules]] governing the progress of science. In essence, he said that for any specific method or norm of science, one can find a historic episode where violating it has contributed to the progress of science. He jokingly suggested that, if believers in the scientific method wish to express a single universally valid rule, it should be '[[#theTermSci|anything goes]]'.<ref>[[Paul Feyerabend|Feyerabend, Paul K.]], ''Against Method, Outline of an Anarchistic Theory of Knowledge'', 1st published, 1975.

A more general inference against formalised method has been found through research involving interviews with scientists regarding their conception of method. This research indicated that scientists frequently encounter difficulty in determining whether the available evidence supports their hypotheses. This reveals that there are no straightforward mappings between overarching methodological concepts and precise strategies to direct the conduct of research.<ref name="Schickore Hangel 2019">{{cite journal | last=Schickore | first=Jutta | last2=Hangel | first2=Nora | title=“It might be this, it should be that…” uncertainty and doubt in day-to-day research practice | journal=European Journal for Philosophy of Science | volume=9 | issue=2 | date=2019 | issn=1879-4912 | doi=10.1007/s13194-019-0253-9 | page=}}</ref>
