The process of establishing a new scientific theory is necessarily a grueling one; new theories must survive an adverse gauntlet of skeptics who are experts in their particular area of science; the original theory may then need to be revised to satisfy those objections. The typical way in which new scientific ideas are debated are through refereed scientific journals, such as Nature and Scientific American. Depending upon the area of science, there are many other journals specific to their respective fields that act as referees.
The first transformation was accomplished by ignoring the implications of a long standing distinction between observing and experimenting.
To experiment is to isolate, prepare, and manipulate things in hopes of producing epistemically useful evidence. It had been customary to think of observing as noticing and attending to interesting details of things perceived under more or less natural conditions, or by extension, things perceived during the course of an experiment.
To look at a berry on a vine and attend to its color and shape would be to observe it. To extract its juice and apply reagents to test for the presence of copper compounds would be to perform an experiment. Contrivance and manipulation influence epistemically significant features of observable experimental results to such an extent that epistemologists ignore them at their peril.
The logical empiricists tended to ignore it. A second transformation, characteristic of the linguistic turn in philosophy, was to shift attention away from things observed in natural or experimental settings and concentrate instead on the logic of observation reports. The shift developed from the assumption that a scientific theory is a system of sentences or sentence like structures propositions, statements, claims, and so on to be tested by comparison to observational evidence.
Secondly it was assumed that the comparisons must be understood in terms of inferential relations. If inferential relations hold Support your theory between sentence like structures, it follows that theories must be tested, not against observations or things observed, but against sentences, propositions, etc.
Schlick Friends of this line of thought theorized about the syntax, semantics, and pragmatics of observation sentences, and inferential connections between observation and theoretical sentences. In doing so they hoped to articulate and explain the authoritativeness widely conceded to the best natural, social and behavioral scientific theories.
Some pronouncements from astrologers, medical quacks, and other pseudo scientists gain wide acceptance, as do those of religious leaders who rest their cases on faith or personal revelation, and rulers and governmental officials who use their political power to secure assent.
But such claims do not enjoy the kind of credibility that scientific theories can attain. The logical empiricists tried to account for this by appeal to the objectivity and accessibility of observation reports, and the logic of theory testing.
Part of what they meant by calling observational evidence objective was that cultural and ethnic factors have no bearing on what can validly be inferred about the merits of a theory from observation reports.
In response to this rationale for ethnic and cultural purging of the German educational system the logical empiricists argued that because of its objectivity, observational evidence, rather than ethnic and cultual factors should be used to evaluate scientific theories.
Less dramatically, the efforts working scientists put into producing objective evidence attest to the importance they attach to objectivity. Furthermore it is possible, in principle at least, to make observation reports and the reasoning used to draw conclusions from them available for public scrutiny.
If observational evidence is objective in this senseit can provide people with what they need to decide for themselves which theories to accept without having to rely unquestioningly on authorities.
Francis Bacon argued long ago that the best way to discover things about nature is to use experiences his term for observations as well as experimental results to develop and improve scientific theories Bacon 49ff. The role of observational evidence in scientific discovery was an important topic for Whewell and Mill among others in the 19th century.
Recently, Judaea Pearl, Clark Glymour, and their students and associates addressed it rigorously in the course of developing techniques for inferring claims about causal structures from statistical features of the data they give rise to Pearl, ; Spirtes, Glymour, and Scheines But such work is exceptional.
Popper31 Drawing a sharp distinction between discovery and justification, the standard philosophical literature devotes most of its attention to the latter.
Although theory testing dominates much of the standard philosophical literature on observation, much of what this entry says about the role of observation in theory testing applies also to its role in inventing, and modifying theories, and applying them to tasks in engineering, medicine, and other practical enterprises.There is no evidence to support such a theory.
He is a specialist in film theory and criticism. See More. Recent Examples on the Web. Our electron, according to theory. Family Systems Theory. The family systems theory is a theory introduced by Dr.
Murray Bowen that suggests that individuals cannot be understood in isolation from one another, but rather as a part of their family, as the family is an emotional unit.
Identify a theory that can be used to support your proposed solution. The theoretical framework that will support this scenario is placated upon Theory of Reasoned Action. This theory is chosen because of the fact that many theories that are placated upon health behavior and how citizens' perceptions of their health evolve are predicated upon.
Theory testing was treated as a matter of comparing observation sentences describing observations made in natural or laboratory settings to observation sentences that should be true according to the theory to be tested. “Behaviorism theory, also known as behavioral psychology is a theory of learning based upon the idea that all behaviors are acquired through conditioning” (Cherry, ).
B.F Skinner and John B. Watson are the two creators of the behaviorism theory. They stated that development included learned behaviors. Identify a nursing theory that can be used to support your proposed solution.
