It’s not just the people you are asking that can cause bias though, the person doing the asking is part of the problem too, and that’s called interviewer bias. Interviewer bias is all about the effect that the person asking the questions has on the sample. Humans generally don’t like confrontation. People worry that their answers will make them look bad, therefore, we find that people tend to give socially desirable responses which is not necessarily their honest opinions because they don’t want to come across heartless or racists. The way we word our questions matters too. When polls purposely sway the answers one way or the other it’s called the push poll because it pushes people to answer a certain way. For example, will you vote for candidate Donald Trump? Is a perfectly normal question or would you vote for candidate Donald Trump if you knew he called all Mexicans rapists? is a push
