"It might be pointed out that this scientific tool, like all others, is in itself neutral and can be used for good or evil according to one's own definition and purposes."

The Sources
A. Published
Only a fraction is published and even a smaller fraction still is easily attainable. For example, when you see in the paper according to "a Gallup Poll published last week" it is not guaranteed that you will be able to find the poll in one of our services.
Also, many marketing-type polls/surveys are prohibitively expensive and therefore in effect not available.
The astute notice this listed above. There is a specific area within this database for polls and surveys. Go to "Reference" and then to "Polls and Surveys."
