There are many philosophical and historical theories as to how scientific consensus changes over time. Because the history of scientific change is extremely complicated, and because there is a tendency to project "winners" and "losers" onto the past in relation to the current scientific consensus, it is very difficult to come up with accurate and rigorous models for scientific change.

But one counter-example can prove it false. That means that deductive logic is used in the evaluation of a theory. In other words, if A implies B, then not B implies not A. Einstein's theory of General Relativity has been supported by many observations using the best scientific instruments and experiments.
A fact can be defined as something that is the case, in other words, a state of affairs. [14] [15] Facts may be understood as information, which makes a true sentence true: "A fact is, traditionally, the worldly correlate of a true proposition, a state of affairs whose obtaining makes that proposition true."
Evidence-based education (EBE), also known as evidence-based interventions, is a model in which policy-makers and educators use empirical evidence to make informed decisions about education interventions (policies, practices, and programs). [27] In other words, decisions are based on scientific evidence rather than opinion.
In other words, it describes the research that has not taken place before and their results. In practice, the accumulation of evidence for or against any particular theory involves planned research designs for the collection of empirical data , and academic rigor plays a large part of judging the merits of research design .
For example, confirmation bias produces systematic errors in scientific research based on inductive reasoning (the gradual accumulation of supportive evidence). Similarly, a police detective may identify a suspect early in an investigation, but then may only seek confirming rather than disconfirming evidence.
Confrontation stage: Presentation of the difference of opinion, such as a debate question or a political disagreement. Opening stage: Agreement on material and procedural starting points, the mutually acceptable common ground of facts and beliefs, and the rules to be followed during the discussion (such as, how evidence is to be presented, and ...
A systematic review is a scholarly synthesis of the evidence on a clearly presented topic using critical methods to identify, define and assess research on the topic. [1] A systematic review extracts and interprets data from published studies on the topic (in the scientific literature), then analyzes, describes, critically appraises and summarizes interpretations into a refined evidence-based ...
