In countries where automobile insurance includes compensation for whiplash injuries sustained in automobile accidents, reports of having suffered such injuries are twice as frequent as they are in countries where whiplash is not covered. Some commentators have argued, correctly, that since <b> there is presently no objective test for whiplash </b>, spurious reports of whiplash injuries cannot be readily identified. These commentators are, however, wrong to draw the further conclusion that <b> in the countries with the higher rates of reported whiplash injuries, half of the reported cases are spurious </b>: clearly, in countries where automobile insurance does not include compensation for whiplash, people often have little incentive to report whiplash injuries that they actually have suffered.
The first boldfaced portion is evidence that has been used to support a conclusion that the argument criticizes and the second is that conclusion.
