When selecting use of a neutral alternative in dichotomous questions what considerations must be kept in mind?
Answer
If a neutral alternative isn't included, respondents are forced to choose between "no" and "yes" even if they feel indifferent. Conversely, if a neutral alternative is included, respondents may avoid taking a position on the issue, thus biasing the results. Following guidelines are offered. If substantial proportion of the respondents can be expected to be neutral, include a neutral alternative. If proportion of neutral respondents is anticipated to be small, avoid the neutral alternative.
