Anatomy of a Political Poll

Politics in Virginia

A new poll has hit the phone lines of Virginia. Run by a group calling itself "Survey 2006," it will show up on caller ID as "S2006 703-961-9120." Survey 2006's polls have been criticized as openly biased, badly written, and even push-polls. This one is no exception.

The computerized voice announces itself as "Survey 2006," though at the end of the poll is notifies the participant that the poll was conducted by "The Family Foundation of Virginia." As lengthy pauses by the participant are detected by the system and may prompt a disconnection, a verbatim copy of the survey will take the collaborative work of several individuals. What follows is a fairly accurate representation of the poll, though some minor differences in phrasing and language exist.

  1. Are you registered to vote in Virginia?
  2. On the issue of abortion, do you consider yourself pro-life?
  3. Do you agree that marriage should be legally defined as between one man and one woman?
  4. [Some background on how taxes may be collected on a persons estate.] Do you support the permanent repeal of the Death Tax?
  5. Do you agree with US efforts in Iraq?
  6. Do you support a tax credit to allow parents to choose where their children go to school?
  7. Do you support the use of unborn fetuses in stem cell research?
  8. Do you support legislation that would require a filter blocking pornography in all public libraries?
  9. Do you think churches should be involved in political issues?
  10. Should women have the right to request anesthesia for their unborn fetus if they elect to have an abortion in the second or third trimester?
  11. Do you trust the Republican Party to spend your tax dollars?
  12. Do you attend church, temple, or synagogue, at least once per week?
  13. Are you male?
  14. Have you ever contributed to a political candidate or political campaign?

While these questions are paraphrased, specific linguistic constructions like "Death Tax" and "Unborn Fetuses" have been preserved to maintain the general tone and framing of the survey. An analysis of the language used and the subtext of questions reveals a series of problems with this poll. Such an analysis follows:

  1. This question exists to create a statistical base for the poll. In this case, registered voters in Virginia.
  2. The decision to use the phrase "pro-life" to the exclusion of "pro-choice" represents a frame of the abortion issue. "Pro-Life" implicates its opposition as "Pro-Death" or "Anti-Life" rather than the more typical "Pro-Choice." This phrasing may introduce some bias into the results of this survey and certainly this question.
  3. Given that Virginia has an amendment on the ballot this year which deals with this issue specifically, this question is unnecessarily vague. Linguistically, however, there is little bias injected into this statement.
  4. The phrase "Death Tax" is a clear frame of the Estate Tax issue and will inject substantial bias into the poll. "Death Tax" implies a more universal and regressive tax than is the case and is typically associated with a strong right-wing agenda.
  5. The phrase "US Efforts" is unnecessarily vague. This question's vagueness allows the question to be interpreted widely by the pollster and renders the question itself meaningless.
  6. The use of the "choice" frame makes this question suspect in much the same manner as the "Death Tax" and "Pro-Life" questions above.
  7. This question uses the phrase "unborn fetuses" making setting up the assumption of birth and therefore the assumption that the fetus is in fact alive. A more honest phrasing of this question would not make this implicit statement.
  8. The "porn filter" question does not use any ideologically loaded frames, but fails to recognize the technical infeasibility of such a filter. Even so, the question, if not its subject matter, remains valid.
  9. The "church involvement in politics" question is well phrased, though the term involvement is somewhat vague. Little to no ideological bias will be injected by this question and it will likely yield valid statistics.
  10. Despite being a very strange question, this seems to harbor no unnecessary frames save for the "unborn fetus" phrase discussed above. This question may represent a push poll of sorts, espousing the position that a fetus can feel pain and may need anesthesia in the first place.
  11. The "Republican Spending" question is well phrased and ideologically balanced. It may serve as a good predictor of party loyalty.
  12. The "Religious Services" question is likely used to establish trends against other questions in the survey. It exhibits no obvious bias.
  13. Gender balance is essential in a poll and allows some statistical correction for social norms..
  14. Contribution to a political campaign can be used to gauge the degree of political activity an individual engages in. This is crucial to the overall statistical results.

It's just another poll is the vast field of American politics, a snapshot of the political terrain. Like all photos, however, it fixes the world as seen through the photographer's eye.

Who's leading the conversation?
This visualization below allows you to see the impact that each user has on the current conversation. The top row contains the group of users who have had the most impact, the 2nd row the group of users who have had the 2nd most impact (et cetera). Users with similar impact are grouped together, and the average score of the group is shown to the left of the group. The author of the article is also shown on the left, in their corresponding group. Each user's score is based on the number of comments the user has made plus the number of votes their comments have received. The scores are calculated relative one another, so while their absolute value is not particularly important, their relative difference does indicate a larger difference in impact on the conversation.

This is a bit of a local interest issue, but I think it's a good idea to discuss the problems with poll bias, particularly as we head into the final stretch of the 2006 election. If anyone else got the Survey2006 poll and has corrections they'd like to offer I'd appreciate them.

Well, I haven't been called (yet), but I can say one thing. When I lived just down the street from your current location, I got more calls from pollsters than anywhere else I've ever lived. I wasn't aware that part of the state was so up for grabs, but I routinely got calls from push pollsters (like this one) and legitimate pollsters as well.

Anyway, the next time the discussion of polls comes up here on Newsvine (which will probably be any time now) and the inevitable these-things-always-lie comes up, I'll point them to this article to demonstrate the difference between a push poll and a legitimate opinion poll. Thanks for outing these guys for the hacks they are. People who really want to take a political temperature spend a great deal of time carefully crafting questions as to be as non-leading as possible and these, as you've described them, mostly appear to not do so.

I recall one poll I tried to answer (before I just hung up on them) regarding the Israeli-Palestinian conflict. They would as who I thought was at fault, then rattle off some "fact" and then ask again. That repeated several times until the pattern was quite clear: they weren't calling to ask my opinion, but rather to form my opinion.

Thanks Jason. I'm afraid that the format of this article doesn't lend itself to the sort of reading that is likely to encourage a wide audience. Nonetheless, if it serves as a helpful reference I'll consider it a success.

I've had the question-"fact"-question poll format tossed at me as well. I'm not sure about the ethics of that one. I'll toss it over to the VT faculty and see what they think.

I would find it perfectly ethical if the purpose was clearly stated (e.g. - I am calling on behalf of the ____— organization to clarify our positions on the issue of ________. Would you mind if I asked you a few questions?). Instead they pretend it's a poll, and that I find misleading. If you do get some good responses from any faculty over there, I at least would be very interested to know them (either here on in another follow-up article).

That's really interesting, KF. It looks from some of the questions rather as if a straw man (abortion in 2nd and 3rd trimester and stem cell research) is being got up in preparation for the elections.

    If question 3 is posed as "Do you agree that marriage should be..." then that is more than just a little bias injected into the question. People are always a little more likely to "agree" than to "disagree." Also, I think "legally" is a bit buried in the question.

    Some people would also be right to criticize "Do you attend church, temple, or synagogue..." which requires the responder to answer within a specific Judeo-Christian framework. A better question would be "Do you attend formal religious practice at a church, temple, synagogue, or other place of worship..." It should also probably include mosque. That isn't to say that the question will bias the results. Instead, it biases the analysis of the results, or, as you say, will be used to "establish trends against other questions" in a very particular way.

    On the other hand, I disagree that question 5 has much bias, though I do think it is so vague as to be useless. It should be followed by more questions that probe support for specific ideas and policies, but if it were, then it would be a legitimate question.

    Good points ignoblus. I'm not sure of the exact listing of various places of worship in the church question, so Mosque may have been included and there may have been a catch-all at the end (though I don't recall one).

      I hope this wouldn't be seen as self-promotion (although, it really is), but this has a lot to do with my most recent article.

      Good article,

      As you point out, it is not hard to create a biased poll, and this one is pretty biased.

      Another "hidden" bias, is the trying to get a truly random sample to respond.

      For example, make the first question clearly supporting abortion and a passionate anti abortionsit is far more likely not to hang up than a pro-abortionist --- or someone that doesn't care that passionately. .

        Thanks for breaking the poll down issue by issue. Polls are always misleading these days. The + or - 4% is a joke.

        I am in California, working in the political direct mail field. Most of the pieces we do nowadays are "hit" pieces, meant to drop right before the election and show the opposing candidate in a negative light. Politics can be an ugly business.

          The + or - 4% is a joke.

          The ±4% (or 3%, common in poll samples of 1,000) is mathematics. If the poll isn't conducted properly, then the results are meaningless. However, the statistics behind the poll error is sound as any introduction to statistics course will prove. Please no one quote Mark Twain to me, either. He was a brilliant mind, but his taking issue with statistics was in how they were used, not developed (which speaks to rstrb8r's comment).
