The Significance of Statistically Insignificant Variables

Statistically insignificant variables are routinely excluded from empirical research in social science and economics despite their theoretical relevance to model formulation. This descriptive cross-disciplinary study documents this practice and illustrates how significance-based reporting might bias theoretical inference and policy consequences. Research in economics, business, psychology, and education shows that statistical thresholds sometimes ignore theoretically sound aspects without further analysis. The study proposes the Significance Recovery Technique (SRT), an interpretative framework for post-estimation that reevaluates non-significant variables based on theoretical coherence, effect direction, and contextual reasoning without changing the econometric estimation process. The framework’s emphasis on open interpretation over selective reporting improves empirical practice, theory-evidence integration, and policy inference. According to the study, statistical insignificance should spur additional research, not indicate analytical irrelevance.
