Falsifiability (or refutability) is a deductive standard of evaluation of scientific theories and hypotheses, introduced by the philosopher of science Karl Popper in his book The Logic of Scientific Discovery (1934). [B] A theory or hypothesis is falsifiable if it can be logically contradicted by an empirical test.
Originally, fallibilism (from Medieval Latin: fallibilis, "liable to error") is the philosophical principle that propositions can be accepted even though they cannot be conclusively proven or justified, [1][2] or that neither knowledge nor belief is certain. [3] The term was coined in the late nineteenth century by the American philosopher ...
Verificationism rejects statements of metaphysics, theology, ethics and aesthetics as meaningless in conveying truth value or factual content, though they may be meaningful in influencing emotions or behavior. [ 1 ] Verificationism was a central thesis of logical positivism, a movement in analytic philosophy that emerged in the 1920s by ...
The fact–value distinction is a fundamental epistemological distinction described between: [ 1 ] Statements of fact (positive or descriptive statements), which are based upon reason and observation, and examined via the empirical method. Statements of value (normative or prescriptive statements), which encompass ethics and aesthetics, and are ...
A formal fallacy, deductive fallacy, logical fallacy or non sequitur (Latin for "it does not follow") is a flaw in the structure of a deductive argument that renders the argument invalid. The flaw can be expressed in the standard system of logic. [ 1 ] Such an argument is always considered to be wrong.
Logical positivism, later called logical empiricism, and both of which together are also known as neopositivism, is a movement whose central thesis is the verification principle (also known as the verifiability criterion of meaning). [1] This theory of knowledge asserts that only statements verifiable through direct observation or logical proof ...
Value theory is the systematic study of values. Also called axiology, it examines the nature, sources, and types of values. As a branch of philosophy, it has interdisciplinary applications in fields such as economics, sociology, anthropology, and psychology. Value is the worth of something, usually understood as a degree that covers both ...
In carefully designed scientific experiments, null results can be interpreted as evidence of absence. [7] Whether the scientific community will accept a null result as evidence of absence depends on many factors, including the detection power of the applied methods, the confidence of the inference, as well as confirmation bias within the community.
