Should an assumption or necessary state be negated, hypotheses depending on it are rejected. This is a form of root cause analysis. According to social constructivist critics, ACH also fails to stress sufficiently (or to address as a method) the problematic nature of the initial formation of the hypotheses used to create its grid.
Testability is a primary aspect of science [1] and the scientific method. There are two components to testability: Falsifiability or defeasibility, which means that counterexamples to the hypothesis are logically possible. The practical feasibility of observing a reproducible series of such counterexamples if they do exist.
Model-based assumptions. These include the following three types: Distributional assumptions. Where a statistical model involves terms relating to random errors, assumptions may be made about the probability distribution of these errors. [5] In some cases, the distributional assumption relates to the observations themselves. Structural assumptions.
Assumption-based planning in project management is a post-planning method that helps companies to deal with uncertainty. It is used to identify the most important assumptions in a company's business plans , to test these assumptions, and to accommodate unexpected outcomes.

Research methodology based on intersubjective dialogue and an egalitarian relationship between the research team and those being researched (Gomez & Latorre, 2005).Current societies are characterized for using dialogue in different domains, seeing it as necessary for social progress and for avoiding different social conflicts (Castells 1996; Flecha, Gómez & Puigvert, 2003; Habermas, 2000).
Difference in differences (DID [1] or DD [2]) is a statistical technique used in econometrics and quantitative research in the social sciences that attempts to mimic an experimental research design using observational study data, by studying the differential effect of a treatment on a 'treatment group' versus a 'control group' in a natural experiment. [3]
Rational analysis is a theoretical framework, methodology, and research program in cognitive science that has been developed by John Anderson. [1] [2] The goal of rational analysis as a research program is to explain the function and purpose of cognitive processes and to discover the structure of the mind.
