Scientific Method
The scientific method is the process chosen by scientists and researchers to investigate or verify a phenomenon. It involves various steps such as making an observation, asking the question, forming the hypothesis, collecting the data, testing the hypothesis, and deriving the conclusion.
Science is always self-correcting as every piece of information is scrutinized over and over again. Often disproving existing information with appropriate evidence is considered a prestigious and high achievement. This is unlike politics, religion, etc where such a person might get prosecuted. It is often regarded as the aim of science is not to proclaim a piece of information as absolute truth but to keep improving a piece of existing information.
