Question

suppose a community proposes a law to require the wearing of seat belts in all moving vehicles.how could scientific research have an impact on the decision?

Answer 1

Do an analysis of accidents and the impact on accident victims, that is what led to the law....people not wearing seatbelts were less likely to survive or had more serious injuries than those that wore them.  Research is done using databases of accidents.  (college prof)
