Epidemiologists study disease distribution and determinants in populations, evaluating whether exposure is associated with increased disease incidence. They interpret cohort and case-control studies and assess causal inference.
They address population-level rather than individual causation.

Why it Matters?
The population-to-individual step is where epidemiological testimony is challenged, since establishing an association in a population does not establish that a particular plaintiff's disease resulted from exposure. The relative risk of two argument operates at that boundary. Epidemiologists testifying to specific causation frequently exceed their discipline, which is a qualification challenge distinct from the reliability of the underlying studies.
