Brief Intro:

Like sailors, who need the visibility to navigate their ship on the right course, researchers need guiding maps to indicate where the biases are in the causal pathway and safely past obstacles threatening the validity of casual inferences. To meet the need for this guiding map, directed acyclic graphs (DAGs) provide a handy tool to help researchers identify and visualize potential variables with significant causal influences.
