General causation asks whether the agent can cause the condition in humans at relevant exposure levels. Proof relies on epidemiology, toxicology, animal studies, and mechanistic evidence.
It is a threshold requirement, and failure to establish it defeats every claim in the litigation regardless of individual circumstances.

General Causation Evidence, Capability Causation
Why it Matters?
This is the single most consequential issue in toxic tort and pharmaceutical litigation because it operates at the inventory level. A successful general causation challenge ends thousands of cases at once, which is why MDL courts often sequence it first through a dedicated Daubert track. Defense investment in epidemiology and methodology critique at this stage carries leverage no case-specific defense can match.
