A manuscript that is entirely based on assumptions presents a hypothesis. Manuscripts written for presentation of empirical findings must be based on data. As Edward Demings said, "In god we trust, all others must bring data". However, in order to analyse data, assumptions must be made. When presenting the analyses its results, the author's presentation must clearly distinguish between observations, assumptions and analysis outcomes. Confusing assumptions and outcomes is not a good thing.
