Navigating Unmeasured Confounding in Quantitative Sociology: A Sensitivity Framework

Unmeasured confounding remains a critical challenge in causal inference for the social sciences. This paper proposes a sensitivity analysis framework to systematically evaluate how unmeasured confounders influence statistical inference in sociology. Given these sensitivity analysis methods, we introduce a five-step workflow that integrates sensitivity analysis into research design rather than treating it as a post-hoc robustness check. Using the Blau and Duncan (1967) study as an empirical example, we demonstrate how different sensitivity methods provide complementary insights. By extending existing frameworks, we show how sensitivity analysis enhances causal transparency, offering a practical tool for assessing uncertainty in observational research. Our approach contributes to a more rigorous application of causal inference in sociology, bridging gaps between theory, identification strategies, and statistical modeling.
