Burden of proof (philosophy) in the context of Warrant (philosophy)

Scientific consensus is the majority judgment and position by active, qualified experts in a specific scientific discipline to establish a conclusion or fact. Scientific consensus results from the self-correcting scientific process of peer review, replication of the event through the scientific method, scholarly debate, meta-analysis, and publication of high-quality review articles, monographs, or guidelines in reputable books and journals to establish facts and durable knowledge about the topic.

Reaching consensus requires significant scientific agreement among qualified experts, a process based on scientific substantiation of a claim that meets the burden of proof by proposing a possible cause-and-effect mechanism supported by the totality of evidence, leading to agreement among experts. In many countries, scientific consensus established on significant scientific agreement is the basis for regulatory approval of drugs to specify a health claim for the properties of the approved therapeutic agent.

Hitchens's razor is a general rule for rejecting certain claims of knowledge. It states:

The razor is credited to author and journalist Christopher Hitchens, although its provenance can be traced to the Latin Quod gratis asseritur, gratis negatur ("What is asserted gratuitously is denied gratuitously"). It implies that the burden of proof regarding the truthfulness of a claim lies with the one who makes the claim; if this burden is not met, then the claim is unfounded, and its opponents need not argue further in order to dismiss it. Hitchens used this phrase specifically in the context of refuting religious belief.
