Which research paradigm holds that rationally justifiable assertions can be scientifically verified?

• A. Interpretivist
• B. Postmodernism
• C. Critical Realism
• D. Positivism

Answer: (D)

Positivism holds that rationally justifiable assertions can be scientifically verified through empirical observation and testing. In this view, knowledge comes from observable, measurable facts and hypotheses that can be tested against experience using the scientific method. Statements are meaningful to the extent they can be analyzed, measured, and potentially falsified by data. This emphasis on verifiability and empirical verification sets positivism apart from interpretivist approaches that focus on individual meanings, postmodern critiques of universal truth, and critical realism, which recognizes a real world but accepts that not all aspects are directly verifiable or observable.
