Processual archaeology (formerly, the New Archaeology ) is a form of archaeological theory . It had its beginnings in 1958 with the work of Gordon Willey and Philip Phillips , Method and Theory in American Archaeology, in which the pair stated that "American archaeology is anthropology, or it is nothing" (Willey and Phillips, 1958:2), a rephrasing of Frederic William Maitland 's comment: "My own belief is that by and by, anthropology will have the choice between being history, and being nothing." The idea implied that the goals of archaeology were the goals of anthropology , which were to answer questions about humans and human culture. This was meant to be a critique of the former period in archaeology, the cultural-history phase in which archaeologists thought that information artifacts contained about past culture would be lost once the items became included in the archaeological record. Willey and Phillips believed all that could be done was to catalogue, describe, and create timelines based on the artifacts.
87-453: Proponents of processual archaeology claimed that the rigorous use of the scientific method made it possible to get past the limits of the archaeological record and to learn something about the lifestyles of those who created or used artifacts. Colin Renfrew , a proponent of processual archaeology, observed in 1987 that it focuses attention on "the underlying historical processes which are at
174-447: A crucial experiment . If the experimental results confirm the predictions, then the hypotheses are considered more likely to be correct, but might still be wrong and continue to be subject to further testing. The experimental control is a technique for dealing with observational error. This technique uses the contrast between multiple samples, or observations, or populations, under differing conditions, to see what varies or what remains

[REDACTED] Watson and Crick showed an initial (and incorrect) proposal for the structure of DNA to a team from King's College London – Rosalind Franklin , Maurice Wilkins , and Raymond Gosling . Franklin immediately spotted the flaws which concerned the water content. Later Watson saw Franklin's photo 51 ,

These processes are initial colonization, replacement, and continuous development. Supported by linguistic analyses, accepted migration progressions, and archeological records, Renfrew proposed

The measurements often require specialized scientific instruments such as thermometers , spectroscopes , particle accelerators , or voltmeters , and the progress of a scientific field is usually intimately tied to their invention and improvement. I am not accustomed to saying anything with certainty after only one or two observations. The scientific definition of
522-490: A culture interact, but performs poorly when describing why they interact the way they do. Despite its lacking, Systems Theory has become a very important part of processualism, as it sets archaeologists with parameters to examine other cultures unique to its peoples, while limiting interference from the researcher's own cultural biases. An example of processualism, in the field of paleolinguistics , Colin Renfrew —who in his 1987 re-examining of Proto-Indo-European language made

If the test results contradict the predictions, the hypotheses which entailed them are called into question and become less tenable. Sometimes the experiments are conducted incorrectly or are not very well designed when compared to

This stage frequently involves finding and evaluating evidence from previous experiments, personal scientific observations or assertions, as well as the work of other scientists. If the answer is already known, a different question that builds on the evidence can be posed. When applying the scientific method to research, determining a good question can be very difficult and it will affect
783-431: A guideline for proceeding: The iterative cycle inherent in this step-by-step method goes from point 3 to 6 and back to 3 again. While this schema outlines a typical hypothesis/testing method, many philosophers, historians, and sociologists of science, including Paul Feyerabend , claim that such descriptions of scientific method have little relation to the ways that science is actually practiced. The basic elements of

It appears to follow that the observation 'this is a green tree' is corroborating evidence for the hypothesis 'all ravens are black'. Attempted resolutions may distinguish: Evidence contrary to a hypothesis is itself philosophically problematic. Such evidence is called a falsification of the hypothesis. However, under

These institutions thereby reduce the research function to a cost/benefit, which is expressed as money, and the time and attention of the researchers to be expended, in exchange for a report to their constituents. Current large instruments, such as CERN's Large Hadron Collider (LHC), or LIGO , or

In general, scientists tend to look for theories that are " elegant " or " beautiful ". Scientists often use these terms to refer to a theory that is following the known facts but is nevertheless relatively simple and easy to handle. Occam's Razor serves as
1305-418: A probability for our confidence in the conjecture itself and then apply a Bayesian analysis , with each experimental result shifting the probability either up or down. Bayes' theorem shows that the probability will never reach exactly 0 or 100% (no absolute certainty in either direction), but it can still get very close to either extreme. See also confirmation holism . Qualification of corroborating evidence
1392-424: A radical new conclusion that contradicted long-held linguistic-origin theories. With Renfrew's proposal being far from conclusive, The New York Times published the findings, claiming that Renfrew's work has since been both supported and challenged in multiple studies by linguists, archaeologists, biologists, geneticists, statisticians, and computational mathematicians. Though Renfrew's conclusions still garner debate,
1479-519: A rule of thumb for choosing the most desirable amongst a group of equally explanatory hypotheses. To minimize the confirmation bias that results from entertaining a single hypothesis, strong inference emphasizes the need for entertaining multiple alternative hypotheses, and avoiding artifacts. [REDACTED] James D. Watson , Francis Crick , and others hypothesized that DNA had a helical structure. This implied that DNA's X-ray diffraction pattern would be 'x shaped'. This prediction followed from
1566-619: A set of phenomena. Normally, hypotheses have the form of a mathematical model . Sometimes, but not always, they can also be formulated as existential statements , stating that some particular instance of the phenomenon being studied has some characteristic and causal explanations, which have the general form of universal statements , stating that every instance of the phenomenon has a particular characteristic. Scientists are free to use whatever resources they have – their own creativity, ideas from other fields, inductive reasoning , Bayesian inference , and so on – to imagine possible explanations for

To prove this, Binford spent time with the Nunamiut of Alaska , a people living in conditions very similar to those of France during the period in question. Binford was successful with this approach, and though his specific problem ultimately eluded complete understanding,

Tests, in this case, must be repeated to substantiate the conjecture (in particular, the probabilities). In this and other cases, we can quantify
1827-584: A term sometimes differs substantially from its natural language usage. For example, mass and weight overlap in meaning in common discourse, but have distinct meanings in mechanics . Scientific quantities are often characterized by their units of measure which can later be described in terms of conventional physical units when communicating the work. New theories are sometimes developed after realizing certain terms have not previously been sufficiently clearly defined. For example, Albert Einstein 's first paper on relativity begins by defining simultaneity and

#17327654249581914-430: Is a proposed description of the scientific method . According to it, scientific inquiry proceeds by formulating a hypothesis in a form that can be falsifiable , using a test on observable data where the outcome is not yet known. A test outcome that could have and does run contrary to predictions of the hypothesis is taken as a falsification of the hypothesis. A test outcome that could have, but does not run contrary to

Crucially, experimental and theoretical results must be reproduced by others within the scientific community.

The scientific method involves careful observation coupled with rigorous scepticism , because cognitive assumptions can distort the interpretation of the observation . Scientific inquiry includes creating a testable hypothesis through inductive reasoning , testing it through experiments and statistical analysis, and adjusting or discarding
2175-410: Is based on the cultural ecology and multilinear evolution ideas of anthropologists such as Julian Steward . In exosomatic adaptation, the culture is determined by its environmental constraints. As a result, processual archaeologists propose that cultural change happens within a set predictable framework, and they seek to understand the adaptation analyzing its components. Moreover, because the framework

If the outcome is already known, it is called a consequence and should have already been considered while formulating the hypothesis . If the predictions are not accessible by observation or experience, the hypothesis
2349-424: Is filled with stories of scientists claiming a "flash of inspiration", or a hunch, which then motivated them to look for evidence to support or refute their idea. Michael Polanyi made such creativity the centerpiece of his discussion of methodology. William Glen observes that the success of a hypothesis, or its service to science, lies not simply in its perceived "truth", or power to displace, subsume or reduce
2436-417: Is not yet testable and so will remain to that extent unscientific in a strict sense. A new technology or theory might make the necessary experiments feasible. For example, while a hypothesis on the existence of other intelligent species may be convincing with scientifically based speculation, no known experiment can test this hypothesis. Therefore, science itself can have little to say about the possibility. In

Note that this method can never absolutely verify (prove the truth of) 2 . It can only falsify 2 . (This is what Einstein meant when he said, "No amount of experimentation can ever prove me right;

Consequently, processual archaeologists hold that cultural changes are driven by evolutionary "processes" in cultural development. The resulting cultural changes would be adaptive relative to the environment. In this framework, the changes within the culture are not only understandable, but also scientifically predictable once
2697-524: Is sometimes called the "New Archaeology." With few notable exceptions such as Boston University , universities in America classify archaeology as a sub-discipline of anthropology, while in Europe it is thought to be a subject more like historical studies. It is important to analyze which sciences are related because such analysis highlights the questions of what archaeology ought to study and in what ways. Like

The hypothesis that 'all ravens are black' would appear to be corroborated by observations of only black ravens. However, 'all ravens are black' is logically equivalent to 'all non-black things are non-ravens' (this is the contrapositive form of the original implication). 'This is a green tree' is an observation of

As in other areas of inquiry, science (through the scientific method) can build on previous knowledge, and unify understanding of its studied topics over time. This model can be seen to underlie the scientific revolution . The overall process involves making conjectures ( hypotheses ), predicting their logical consequences, then carrying out experiments based on those predictions to determine whether

His cautionary example was the gene; the gene was much more poorly understood before Watson and Crick's pioneering discovery of the structure of DNA; it would have been counterproductive to spend much time on the definition of the gene, before them. [REDACTED] Linus Pauling proposed that DNA might be a triple helix . This hypothesis
3306-589: The "scientific method" and in doing so largely replaced the notion of science as a homogeneous and universal method with that of it being a heterogeneous and local practice. In particular, Paul Feyerabend, in the 1975 first edition of his book Against Method , argued against there being any universal rules of science ; Karl Popper , and Gauch 2003, disagree with Feyerabend's claim. Later stances include physicist Lee Smolin 's 2013 essay "There Is No Scientific Method", in which he espouses two ethical principles , and historian of science Daniel Thurs' chapter in
3393-449: The 1830s and 1850s, when Baconianism was popular, naturalists like William Whewell, John Herschel and John Stuart Mill engaged in debates over "induction" and "facts" and were focused on how to generate knowledge. In the late 19th and early 20th centuries, a debate over realism vs. antirealism was conducted as powerful scientific theories extended beyond the realm of the observable. The term "scientific method" came into popular use in

3654-455: The New Archaeology would face particular opposition from amateurs, historical archaeologists, and practical excavators but argued that such individuals would still benefit from the theory's adoption. Processualism began to be critiqued soon after it emerged, initiating a theoretical movement that would come to be called post-processualism . Post-processualist critics consider the main weaknesses of processual archaeology to be: Writing in 1987,
3741-465: The archaeologist Christopher Chippindale of Cambridge University spoke on the view of processualism at that time, putting it in the context of the 1960s, when he stated that: The sharper students of the current generation reasonably regard the "New Archaeology" in its pristine form as a period piece, as strange an artefact of that remote era as the Paris évènements or Woodstock . They have some cause:
3828-446: The basic method used for scientific inquiry. 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 sciences than social sciences . Nonetheless, the cycle of formulating hypotheses, testing and analyzing the results, and formulating new hypotheses, will resemble
3915-467: The contrary, if the astronomically massive, the feather-light, and the extremely fast are removed from Einstein's theories – all phenomena Newton could not have observed – Newton's equations are what remain. Einstein's theories are expansions and refinements of Newton's theories and, thus, increase confidence in Newton's work. An iterative, pragmatic scheme of the four points above is sometimes offered as
4002-553: The cycle described below. The scientific method is an iterative, cyclical process through which information is continually revised. It is generally recognized to develop advances in knowledge through the following elements, in varying combinations or contributions: Each element of the scientific method is subject to peer review for possible mistakes. These activities do not describe all that scientists do but apply mostly to experimental sciences (e.g., physics, chemistry, biology, and psychology). The elements above are often taught in
4089-557: The educational system as "the scientific method". The scientific method is not a single recipe: it requires intelligence, imagination, and creativity. In this sense, it is not a mindless set of standards and procedures to follow but is rather an ongoing cycle , constantly developing more useful, accurate, and comprehensive models and methods. For example, when Einstein developed the Special and General Theories of Relativity, he did not in any way refute or discount Newton's Principia . On

In his 2010 book on archaeological theory Matthew Johnson, then of the University of Southampton , now at Northwestern University , argued that despite the 40 years since its development, the "intellectual questions" first posed by processualism remained "absolutely central" to archaeology. Processual archaeologist David L. Clarke suggested that

They were guided by the bond lengths which had been deduced by Linus Pauling and by Rosalind Franklin 's X-ray diffraction images. The scientific method is iterative. At any stage, it is possible to refine its accuracy and precision , so that some consideration will lead

The new methodological approaches of the processual research paradigm include logical positivism (the idea that all aspects of culture are accessible through the material record), the use of quantitative data, and the hypothetico-deductive model (scientific method of observation and hypothesis testing). During

For example: By 1027, Alhazen , based on his measurements of the refraction of light, was able to deduce that outer space was less dense than air , that is: "the body of the heavens is rarer than the body of air".

Ethno-historical research involves living and studying the life of those who would have used the artifacts—or at least studying
4611-468: The future, a new technique may allow for an experimental test and the speculation would then become part of accepted science. For example, Einstein's theory of general relativity makes several specific predictions about the observable structure of spacetime , such as that light bends in a gravitational field , and that the amount of bending depends in a precise way on the strength of that gravitational field. Arthur Eddington 's observations made during
4698-442: The hypothesis based on the results. Although procedures vary between fields , the underlying process is often similar. In more detail: the scientific method involves making conjectures (hypothetical explanations), predicting the logical consequences of hypothesis, then carrying out experiments or empirical observations based on those predictions. A hypothesis is a conjecture based on knowledge obtained while seeking answers to
4785-397: The hypothesis corroborates the theory. It is then proposed to compare the explanatory value of competing hypotheses by testing how stringently they are corroborated by their predictions. One example of an algorithmic statement of the hypothetico-deductive method is as follows: One possible sequence in this model would be 1 , 2 , 3 , 4 . If the outcome of 4 holds, and 3
4872-678: The interaction of the variables is understood. In effect, archeologists should then be able to completely reconstruct these "cultural processes." Hence the name "processual archaeology," and its practitioners becoming known as "new archaeologists". Scientifically however, the challenge facing proponents of New archaeology was developing a methodology of analyzing the archaeological remains in a more scientific fashion, as no such framework existed. The lack of this type of analysis in works of archeological science led Willey and Phillips to state in 1958, "So little work has been done in American archaeology on
4959-444: The late 1960s and into the 1970s, archaeologist Kent Flannery began championing the idea that systems theory could be used in archaeology to approach questions of culture from an unbiased perspective, as the study focuses on the symbiotic whole of a culture rather than its parts, or artifacts. Systems theory however, proved to have problematic limitations for archaeology as a whole, in that it works well when describing how elements of

Einstein's paper then demonstrates that they (viz., absolute time and length independent of motion) were approximations. Francis Crick cautions us that when characterizing a subject, however, it can be premature to define something when it remains ill-understood. In Crick's study of consciousness , he actually found it easier to study awareness in

Researchers in Bragg's laboratory at Cambridge University made X-ray diffraction pictures of various molecules , starting with crystals of salt , and proceeding to more complicated substances. Using clues painstakingly assembled over decades, beginning with its chemical composition, it was determined that it should be possible to characterize
5220-405: The original conjecture was correct. However, there are difficulties in a formulaic statement of method. Though the scientific method is often presented as a fixed sequence of steps, these actions are more accurately general principles. Not all steps take place in every scientific inquiry (nor to the same degree), and they are not always done in the same order. There are different ways of outlining

Archaeology, and in particular archaeology of the historical period, has sometimes been allied more with humanities disciplines, such as Classics.

The systematic, careful collection of measurements or counts of relevant quantities is often the critical difference between pseudo-sciences , such as alchemy, and science, such as chemistry or biology. Scientific measurements are usually tabulated, graphed, or mapped, and statistical manipulations, such as correlation and regression , performed on them. The measurements might be made in

Detailed record-keeping is essential, to aid in recording and reporting on the experimental results, and supports the effectiveness and integrity of the procedure.

The hypothetico-deductive approach contrasts with other research models such as the inductive approach or grounded theory. In the data percolation methodology, the hypothetico-deductive approach is included in a paradigm of pragmatism by which four types of relations between the variables can exist: descriptive, of influence, longitudinal or causal.

One theory that influences this is Leslie White 's theory that culture can be defined as the exosomatic (outside the body) means of environmental adaptation for humans. That is, archaeologists study cultural adaptation to environmental change rather than the humans' adaptation over generations, which is dealt with by evolutionary biologists. This focus on environmental adaptation

Archaeology, he noted, "has learnt to speak with greater authority and accuracy about the ecology of past societies , their technology, their economic basis and their social organization. Now it is beginning to interest itself in the ideology of early communities: their religions, the way they expressed rank, status and group identity."

Staddon (2017) argues it is a mistake to try following rules in the absence of an algorithmic scientific method; in that case, "science is best understood through examples". But algorithmic methods, such as disproof of existing theory by experiment have been used since Alhacen (1027) and his Book of Optics , and Galileo (1638) and his Two New Sciences , and The Assayer , which still stand as scientific method. The scientific method
7047-416: The twentieth century; Dewey's 1910 book , How We Think , inspired popular guidelines , appearing in dictionaries and science textbooks, although there was little consensus over its meaning. Although there was growth through the middle of the twentieth century, by the 1960s and 1970s numerous influential philosophers of science such as Thomas Kuhn and Paul Feyerabend had questioned the universality of
7134-422: The view that the character, scale and rapidity of recent change is of no greater significance than that experienced in other twenty-year spans of archaeological development. We seem rather to have witnessed an interconnected series of dramatic, intersecting and international developments which together may be taken to define new archaeologies within a New Archaeology; whether we choose to use these terms or avoid them
7221-434: The work of Cochran, Crick and Vand (and independently by Stokes). The Cochran-Crick-Vand-Stokes theorem provided a mathematical explanation for the empirical observation that diffraction from helical structures produces x-shaped patterns. In their first paper, Watson and Crick also noted that the double helix structure they proposed provided a simple mechanism for DNA replication , writing, "It has not escaped our notice that
7308-405: Was able to infer that Earth's atmosphere was 50 miles thick, based on atmospheric refraction of the sun's rays. This is why the scientific method is often represented as circular – new information leads to new characterisations, and the cycle of science continues. Measurements collected can be archived , passed onwards and used by others. Other scientists may start their own research and enter
7395-409: Was also considered by Francis Crick and James D. Watson but discarded. When Watson and Crick learned of Pauling's hypothesis, they understood from existing data that Pauling was wrong. and that Pauling would soon admit his difficulties with that structure. A hypothesis is a suggested explanation of a phenomenon, or alternately a reasoned proposal suggesting a possible correlation between or among
7482-587: Was particular development aided by theoretical works by a skeptic Francisco Sanches , by idealists as well as empiricists John Locke , George Berkeley , and David Hume . C. S. Peirce formulated the hypothetico-deductive model in the 20th century, and the model has undergone significant revision since. The term "scientific method" emerged in the 19th century, as a result of significant institutional development of science, and terminologies establishing clear boundaries between science and non-science, such as "scientist" and "pseudoscience", appearing. Throughout
7569-520: Was the development of the New Archaeology. As a result, he argued, archaeology had suffered a "loss of innocence" as archaeologists became skeptical of the work of their predecessors. Clarke's paper would later be described as "one of the seminal statements of the New Archaeology, by one of its leading proponents" in Britain, if not elsewhere, by the archaeologists Caroline Malone and Simon Stoddart. Processualism's development transformed archaeology, and
