When a person’s normal state is more fragile than a normal person, due to an inherent weakness or a pre-existing vulnerability or condition; the person who has committed a harm (tortfeasor) is responsible for the injured victim as they are; the tortfeasor is required to compensate for all damages he caused, even if damages are elevated compared to a norm because the plaintiff was “thin skulled.” This is also commonly referred to as the “egg-shell” rule.
