Causal Inference
Causal Inference problems require drawing conclusions about cause-and-effect relationships based on observed patterns, temporal sequences, and statistical correlations. You must distinguish between correlation and causation, consider alternative explanations, and determine what causal conclusions are reasonably supported by the evidence.

Introduction to Causal Inference
Causal Inference problems require drawing conclusions about cause-and-effect relationships based on observed patterns, temporal sequences, and statistical correlations. You must distinguish between correlation and causation, consider alternative explanations, and determine what causal conclusions are reasonably supported by the evidence.
Prerequisites
How to Solve Causal Inference Problems
Step 1: Identify the observed relationship (temporal order, correlation)
Step 2: Check temporal precedence: cause must occur before effect
Step 3: Consider alternative explanations (confounding variables)
Step 4: Assess strength of the causal evidence
Step 5: Use appropriate causal language ('likely caused', 'contributed to', 'may be due to')
Step 6: Avoid claiming certainty unless strongly supported
Step 7: Select the most reasonable causal inference
Example Problem
Example: Sales increased by 40% after the advertising campaign launched. What causal inference is most reasonable? Solution: Step 1: Observation: Sales increased after advertising campaign Step 2: Temporal precedence: campaign occurred before increase Step 3: Alternative explanations: seasonal factors, competitor actions, economic changes Step 4: Reasonable inference: campaign likely contributed to increased sales Step 5: Not certain, but probable given temporal order Answer: The advertising campaign likely caused or contributed to the sales increase
Pro Tips & Tricks
- Correlation does not imply causation
- Temporal precedence is necessary for causation
- Consider confounding variables that might explain both
- Randomized controlled trials provide strongest causal evidence
- Observational studies suggest correlation, not causation
- Use 'likely', 'probably', 'may have caused' for reasonable inferences
