Question wording bias

The problem sits in the question itself rather than in who was sampled, which makes it a form of response bias. For example, asking "Do you support wasteful spending on a new stadium?" pulls answers toward no in a way that neutral wording would not. Loaded adjectives and the order the questions come in do the same thing. A separate strand of response bias comes from self-reported answers on topics people are embarrassed to answer honestly. A larger sample just asks the same slanted question more times, so it does not improve the estimate.
