Many important questions about cause and effect are impractical to answer with a randomized experiment. What should we do instead? In this episode we talk about doing causal inference with observational data. Has psychology's historical obsession with internal validity led it, ironically, to think about causal inference in an unsophisticated way? Can formal analytic tools like directed acyclic graphs (DAGs) tell us how to do better studies? Or is their main lesson don't bother trying? How do norms and incentives in publishing help or hurt in doing better causal inference? Plus: We answer a letter about applying to psychology grad school when your background is in data science.
