Presidential Polls Not As Valid As Claimed
still not close enough to the results of the other polls to be explained by the standard margin of error.An additional point raised in the article is that polls tend to show large shifts in opinion over a short time. Yet these are frequently short-lived. "Polls do not differentiate between long-held belief and fleeting feelings," stated Perlstein. Generally, large shifts in opinion in short periods only occur with major events. And the best way to comprehend public opinion, the article states, is not from one poll from a single organization but from looking at the results of polls by different surveying organizations and then see how these change over time. "Different organizations independently confirming the results of others is similar to a group of scientists replicating the experimental results of other groups of scientists. This demonstrates validity," Perlstein claims.The News Informant article in its entirety, and its sources, can be found on the web at: http://www.newsinformant.com/2004_09_20/politics.php#000798.
