The following criteria can be used to judge causality:
- The magnitude of the association
- Consistency (same effect shown in different studies carried out in different populations).
- Temporal relationship (cause must precede effect)
- Coherence of explanation (also known as biological plausibility).
- Dose-response relationship.
Why is it that people just don’t get causation does not indicate correlation?
