Everyone knows that question wording skews answers. Absolutely everyone! Edward Snowden knows. When discussing (in Wired magazine, 9/14, p. 9) whether or not public opinion has shifted in favor of curtailing mass surveillance, he says: `”It depends a lot on the polling question'”.
Gore Vidal knows: “it’s how the question is asked that determines the response” (Perpetual War for Perpetual Peace, p. 59).
Answers are driven by questions, so when you want to find out what’s really going on, don’t ask. Instead, observe, experiment, and so on; all of which is discussed in my book, The Problem with Survey Research.
