A working hypothesis is a hypothesis that is provisionally accepted as a basis for further ongoing research[1] in the hope that a tenable theory will be produced, even if the hypothesis ultimately fails.[2] Like all hypotheses, a working hypothesis is constructed as a statement of expectations, which can be linked to deductive, exploratory research[3][4] in empirical investigation and is often used as a conceptual framework in qualitative research.[5][6] The term "working" indicates that the hypothesis is subject to change.[3]

hypothesis [...]—Working hypothesis, a hypothesis suggested or supported in some measure by features of observed facts, from which consequences may be deduced which can be tested by experiment and special observations, and which it is proposed to subject to an extended course of such investigation, with the hope that, even should the hypothesis thus be overthrown, such research may lead to a tenable theory.
