Response bias is a type of statistical bias which can affect the results of a statistical survey if respondents answer questions in the way they think the questioner wants them to answer rather than according to their true beliefs. This may occur if the questioner is obviously angling for a particular answer (as in push polling) or if the respondent wishes to please the questioner by answering what appears to be the "morally right" answer. An example of the latter might be if a woman surveys a man on his attitudes to domestic violence, or someone who obviously cares about the environment asks people how much they value a wilderness area. In statistics, the term bias is used for two different concepts. ... Statistical surveys are used to collect quantitative information about items in a population. ...

This occurs most often in the wording of the question. Response bias is present when a question contains a leading opinion. For example, saying "Even though at the age of 18 people are old enough to fight and die for your country, don't you think they should be able to drink alcohol as well?" yields a response bias. To fix this, you would say "Do you think 18 year olds should be able to drink alcohol?"
It also occurs in situations of voluntary response, such as phone-in polls, where the people who care enough to call are not necessarily a statistically representative sample of the actual population.
