Responses of Don’t Know or No Answer for 28 New York Times/CBS polls. Blocks represent the density of observed DK/NA percentages for the 28 polls. The black line represents the probability of each DK/NA rate given a poisson distribution. The green dotted line depicts the mean of the observations. The black dotted lines depict two standard deviations above and below the mean. The most recent Syria poll, with a 14% DK/NA rate, is well above 10.5 (two standard deviations above the mean). The question is therefore highly unlikely to be valid and should be clarified for future polls.
CBS News and the New York Times released a poll yesterday on opinions regarding Syria. The poll posed a question to 965 adults nationwide worded as such: “Do you think the United States has a responsibility to do something about the fighting in Syria between government forces and anti-government groups, or doesn’t the United States have this responsibility?” Answers included “Yes” by 24% of respondents and “No” by 62% of respondents. CBS headlines interpreted the poll as “Americans Against Intervention in Syria.” The New York Times stated, “Americans are exhibiting an isolationist streak, with majorities across party lines decidedly opposed to American intervention in North Korea or Syria, according to the latest New York Times/CBS News poll.”
While the wording of the poll question on North Korea was acceptable, the question on Syria was ambiguous due to usage of the word “responsibility” and the phrase “do something”. It would be very possible to think that the US has no responsibility to act in Syria, but should do something nonetheless. It is also possible to think that the U.S. has a responsibility to do something, but should nevertheless refrain from acting. Finally, “doing something” is ambiguous, and does not necessarily mean “intervention” as asserted in the reporting of the poll by the New York Times. The biases are countervailing, and lead to ambiguity. Continue reading
