In the scientific method, the self-correcting nature of science usually means that mistakes or even deceptions do not last long.

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.

Alenkinab [10]
The one advantage of using DNS assay to detect maltose production is the formation of a soluble and colored product compound. 
The reaction that occurs between maltose and DNS in the assay is a redox reaction (reduction and oxidation) such that maltose gets oxidized and becomes Maltonic Acid while the DNS gets reduced into reduced DNS. The  intensity of orange/brown /red color of reduced DNS is proportionately related to the amount of Maltose in the solution.
