There are several reasons for refusing to participate in the study. Mainly – it's the fear of consequences. The study also may be perceived as an invasion of privacy. In addition, people can be unfriendly configured in relation to the researcher. Mashable is full of insight into the issues. Error unable to answer. Respondents may be unable to respond if they did not know or forgot, they also may be unable to properly express it.

Problems in each of these cases may be even worse if the respondents will invent answers, because they do not want to admit his incompetence, or want to have a courtesy to the interviewer.

However, today in the growing market research there are more and more professionals with a distant view of authenticity. Their formula – "credible '=' true '. Their customers should be careful, taking for granted a 'truth'.
