The doctrine of contributory negligence is followed in most states is false.

Explanation:

Contributory negligence is a doctrine of common law that if a person was injured in part due to his/her own negligence, that is his/her negligence contributed to the accident, the injured party would not be entitled to collect any damages (money) from another party who supposedly caused the accident.

And historically, contributory negligence was the rule in all states, leading to harsh results. Many states now developed and adopted comparative negligence laws. Today, the jurisdictions that still use contributory negligence are few.
