Yes. I decided to submit to a poll a few months ago.
The people who call have no input and no discretion. They have the questions. You have to answer the questions as put.
Many times the questions are loaded and make no sense and provide no way for you to give a reasonable alternative.
Polls can be so easily manipulated. Then they are printed, become gospel and are taken as such.
The only real polls are on election days.
Wording and placement of questions do influence results. So also do sample composition and timing. Sometimes, as in the Teri Shiavo case, a push poll read a paragraph about it to people who had heard nothing yet and then the media used the results of that hypothetical to tell us what we should be thinking.
