Are holist underdetermination and contrastive underdetermination mutually exclusive in any ways?

What is the conclusion of the underdetermination argument?

To show that a conclusion is underdetermined, one must show that there is a rival conclusion that is equally well supported by the standards of evidence. A trivial example of underdetermination is the addition of the statement “whenever we look for evidence” (or more generally, any statement which cannot be falsified).

What is the underdetermination argument against scientific realism?

The argument form the empirical underdetermination of theories against scientific realism is that in principle any body of empirical data, no matter how large, is compatible with an infinite number of possible incompatible theories.

What is the underdetermination principle?

Underdetermination is a thesis explaining that for any scientifically based theory there will always be at least one rival theory that is also supported by the evidence given, and that that theory can also be logically maintained in the face of any new evidence.

What is holistic underdetermination?

Holist underdetermination (Section 2 below) arises whenever our inability to test hypotheses in isolation leaves us underdetermined in our response to a failed prediction or some other piece of disconfirming evidence.

What is the difference between local and global underdetermination?

Both claims are generically labeled “Duhem–Quine underdetermination.” The global version says that any given set of data can always be represented by different, conceptually incompatible accounts; the local variant suggests that arbitrary hypotheses can be maintained in the face of arbitrary evidence if one is prepared

What does it mean to say that observations are theory laden?

Theory-ladenness of observation holds that everything one observes is interpreted through a prior understanding of other theories and concepts. Whenever we describe observations, we are constantly utilizing terms and measurements that our society has adopted.

What is empirically equivalent?

Two theories are empirically equivalent if they share all consequences expressed in purely observational vocabulary. This is a much stronger requirement than has hitherto been recognised – two such ‘rival’ theories must in fact agree on many claims that are clearly theoretical in nature.

What is holism about testability?

In philosophy of science, confirmation holism, also called epistemological holism, is the view that no individual statement can be confirmed or disconfirmed by an empirical test, but rather that only a set of statements (a whole theory) can be so.

What is the demarcation problem in philosophy of science?

In philosophy of science and epistemology, the demarcation problem is the question of how to distinguish between science and non-science. It examines the boundaries between science, pseudoscience, and other products of human activity, like art and literature, and beliefs.

What are the differences between local and global evidence?

Global evidence is the best starting point for judgements about effects, factors that modify those effects, and insights into ways to approach and address problems. But local evidence is needed for most other judgements about what decisions and actions should be taken.

What is instrumentalist theory?

instrumentalism, in the philosophy of science, the view that the value of scientific concepts and theories is determined not by whether they are literally true or correspond to reality in some sense but by the extent to which they help to make accurate empirical predictions or to resolve conceptual problems.

What do logical positivists believe?

logical positivism, also called logical empiricism, a philosophical movement that arose in Vienna in the 1920s and was characterized by the view that scientific knowledge is the only kind of factual knowledge and that all traditional metaphysical doctrines are to be rejected as meaningless.

Are all observations theory laden?

All observations and uses of observational evidence are theory laden in this sense (cf. Chang 2005, Azzouni 2004). As the example of the thermometer illustrates, analogues of Norwood Hanson’s claim that seeing is a theory laden undertaking apply just as well to equipment generated observations (Hanson 1958, 19).

Are the observations in all the cases the same or different?

Answer. Answer: So, the unit of observation and the unit of analysis can be the same but they need … So it all depends on the design.

Is Laden a scientific theory?

In the philosophy of science, observations are said to be “theory-laden” when they are affected by the theoretical presuppositions held by the investigator.

What is the cornerstone of scientific discovery?

Specifically, scientific laws must be simple, true, universal, and absolute. They represent the cornerstone of scientific discovery, because if a law ever did not apply, then all science based upon that law would collapse.

Can anything done scientifically be relied upon to be accurate and reliable?

Anything done scientifically can be relied upon to be accurate and reliable. Different scientists may get different solutions to the same problem. Results can be influenced by the race, gender, nationality, religion, politics or economic interests of the scientist.

What is the information gathered by observation or experimentation when it is not called evidence?

Bias. The objective of science is that all empirical data that has been gathered through observation, experience and experimentation is without bias.

How can evidence from an experiment be explained in relationship to the hypothesis?

A conclusion relates the evidence to the hypothesis and inference is a guess. A conclusion explains data and an inference is predicts what will occur next. A conclusion provides less information to the reader than an inference.

What is the relationship between an experiment and a hypothesis?

A hypothesis is a tentative explanation that can be tested by further investigation. A theory is a well-supported explanation of observations. A scientific law is a statement that summarizes the relationship between variables. An experiment is a controlled method of testing a hypothesis.
