The case for a posteriori hypotheses to fuel scientific progress

Area of Science:

• Scientific Methodology
• Philosophy of Science

Background:

• A priori hypotheses are standard in science.
• A posteriori hypotheses are often dismissed as inappropriate.
• Current practices inadequately acknowledge a posteriori hypotheses.

Purpose of the Study:

• Advocate for the formal recognition and clear statement of a posteriori hypotheses.
• Highlight the role of a posteriori hypotheses in advanced scientific thinking.
• Encourage the use of a posteriori hypotheses to facilitate scientific progress.

Main Methods:

• Conceptual analysis of scientific methodology.
• Argumentation for the integration of a posteriori hypotheses in research publications.

Main Results:

• A posteriori hypotheses, arising from new observations, can be valuable.
• Testing of a posteriori hypotheses may occur in future studies.
• Unambiguous formulation of a posteriori hypotheses aids follow-up research.

Conclusions:

• A posteriori hypotheses should be encouraged as a key tool for researchers.
• Formal requirement of reporting a posteriori hypotheses in publications is suggested.
• Embracing a posteriori hypotheses can enhance the pace of scientific discovery.
