Let’s stop the SLOP

The Fallacy of Online Surveys: No Data Are Better Than Bad Data

A Recently Published Responsive Management Journal Article Outlines Why Online Surveys Continue to Yield Inaccurate, Unreliable, and Biased Data

INTERNET OR ONLINE SURVEYS have become a popular and attractive way to measure opinions and attitudes of the general population and more specific groups within the general population. Although onlinesurveys may seem to be more economical and easier to administer than traditional survey research methods, they pose several problems to obtaining scientifically valid and accurate results. A peer-reviewed article by Responsive Management staff published in the January-February 2010 issue of Human Dimensions of Wildlife details the specific issues surrounding the use of online surveys in human dimensions research. Reprints of the article can be ordered here. Responsive Management would like to thank Jerry Vaske of Colorado State University for his assistance with the Human Dimensions article and for granting us permission to distribute this popularized version of the article.

    Just to hammer home the point, in one recent especially sloppy philosophical SLOP, the word is that it was possible to vote early and often. That’s right, from the reports I’ve heard, people could vote their way multiple times. The bigots, according to the poll results, albeit faulty, won. So the poll’s author congratulates himself for having done a fine job.
