Positivism
Observable evidence and law-like explanation
Positivism is a family of philosophical positions emphasising systematic observation and scientific explanation of regularities. Applied research accounts commonly stress operational definitions, measurement and hypothesis testing. Historical positivism and contemporary textbook versions differ, so a study should specify its commitments rather than equate all numerical research with one philosophy.
Use where constructs can be operationalised and the question concerns observable regularities or testable relationships, with an explicit plan for measurement, comparison and replication.
Strengths
- Encourages explicit operational definitions and testable predictions
- Supports systematic comparison and replicable procedures
Limitations
- Measurement can miss contextual meanings
- Strong claims of researcher neutrality can conceal consequential value choices
Know the boundary
Numbers alone do not make a study positivist, and a statistically significant association does not establish causation.
