We have discussed at length the fact that negligence means the careless conduct by an individual causing an injury. However, even if another individual caused an injury, the injured party must be completely blame-free or he will not be permitted to recover. So, a plaintiff cannot recover if his carelessness is a cause of the injury. Similarly, if an individual assumes the risk, for instance, of jumping off a cliff into water without knowing how deep the water is, they could be both contributorily negligent (acting carelessly) and assuming a known risk that there were jagged edged rocks beneath the water. In either situation, the plaintiff would be barred from recovering.
