Ahhh, as in yoga, so must we be in our questioning of the subject. Every question we ask must be free of bias, which can take many forms. One is the unbalanced question. The full range of response options must be made clear to the respondent, lest they be led astray. Is the question, “When it comes to imposing tariffs on China, do agree with the President?” balanced? It is not. You must state both response choices in the question lest you “push” your respondent towards agreement.
Here’s another, possibly tougher example. Is the question, “Is the issue of homelessness very important, somewhat important, not that important or not at all important to you?” balanced? It is not. The “somewhat important” response is the conceptual mid-point here, but not the literal mid-point. While we offer two response choices that are less important than “somewhat important,” we only offer one choice that is more important. The imbalance will tend to lead to fewer respondents choosing the top response. We correct this imbalance by adding a response choice of “extremely important.”
