It is the violation of scientific integrity: violation of the scientific method and of research ethics in science, including in the design, conduct, and reporting of research. A Lancet review on Handling of Scientific Misconduct in Scandinavian countries provides the following sample definitions, [1] reproduced in The COPE report 1999: [2]
Baruch, a psychology graduate student at the time, saw an opportunity in psychological research to explain this tendency. [8] Daniel Kahneman, who researched hindsight bias.

How, then, can data ever be sufficient to prove a theory? This is the " epistemological problem of the indeterminacy of data to theory". The poverty of the stimulus argument and W.V.O. Quine 's 1960 'Gavagai' example are perhaps the most commented variants of the epistemological problem of the indeterminacy of data to theory.
Data cleansing may also involve harmonization (or normalization) of data, which is the process of bringing together data of "varying file formats, naming conventions, and columns", [2] and transforming it into one cohesive data set; a simple example is the expansion of abbreviations ("st, rd, etc." to "street, road, etcetera").
