It may be the case that several sufficient conditions, when taken together, constitute a single necessary condition (i.e., individually sufficient and jointly necessary), as illustrated in example 5. Example 1 "John is a king" implies that John is male. So knowing that John is a king is sufficient to knowing that he is a male. Example 2
A proof is sufficient evidence or a sufficient argument for the truth of a proposition. [1] [2] [3] [4]The concept applies in a variety of disciplines, [5] with both the nature of the evidence or justification and the criteria for sufficiency being area-dependent.
Hasty generalization is an informal fallacy of faulty generalization, which involves reaching an inductive generalization based on insufficient evidence [3] —essentially making a rushed conclusion without considering all of the variables or enough evidence.
If its subject is amenable to definition, then the first sentence should give a concise definition: where possible, one that puts the article in context for the nonspecialist. [7] Similarly, if the subject is a term of art, provide the context as early as possible. [8] If the article is about a fictional character or place, make sure to say so. [9]
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.
"Extraordinary claims require extraordinary evidence" (sometimes shortened to ECREE), [1] also known as the Sagan standard, is an aphorism popularized by science communicator Carl Sagan. He used the phrase in his 1979 book Broca's Brain and the 1980 television program Cosmos .
[9] [7] Sentences may either be clearly acceptable or clearly unacceptable, but there are also sentences that are partially acceptable. Hence, according to Sprouse, the difference between grammaticality and acceptability is that grammatical knowledge is categorical, but acceptability is a gradient scale.
Only evidence of that type is relevant to believing one of these conclusions. Therefore, there is no evidence for believing one among the rival conclusions. The first premise makes the claim that a theory is underdetermined. The second says that rational decision (i.e. using available evidence) depends upon insufficient evidence.
