Why is it not possible to accept or reject any micro economic theory with a perfect certainty?

Microeconomic theories often rely on assumptions and simplifications that may not capture the complexities of real-world behavior. Factors such as human psychology, market dynamics, and external influences introduce uncertainty and variability that can affect outcomes. Additionally, the availability of data and the methods used for analysis can lead to differing interpretations, making it challenging to definitively accept or reject a theory. Consequently, economic theories remain subject to ongoing debate and refinement rather than absolute confirmation.
