The purpose of these polls has varied from those designed to understand human behavior (done by Social Scientists) to the media’s desire to report who is ahead and who is behind in electoral contests to those seeking to manipulate voters’ attitudes or to reveal the mating habits of college students. Often the real intent of these polls was not to inform the public, but either to manipulate or entertain it.
