The big picture: DAG Reasoning for Adjustment
Which path are you trying to block without opening another?
Why a policy analyst should care
Adjustment can remove bias or create it, and a causal diagram makes the assumed pathways explicit before the model mechanically controls for variables.
Follow the idea from the opening question to a practical decision. These are the conceptual moves this module will develop:
1 Question Which path are you trying to block?
2 Explore Condition on one variable
3 Formalize Paths encode an analytical argument
4 Transfer Defend an adjustment set
