Motivation

Many problems in developing countries can only be solved by involving citizens and changing social norms in societies. It is therefore crucial to learn more about individuals’ beliefs, attitudes, preferences, and subjective norms. But survey research on such issues has to deal with different forms of bias. For example, respondents might untruthfully answer survey questions in line with social norms, political rules, and in a way to please the researchers. Multifactorial survey experiments (MFSEs) can help to avoid such biases since they do not measure the concepts directly via single survey items but indirectly, based on the variation of different factors. They further single-out the importance of different factors and combinations thereof for evaluating social, economic or political problems. Therefore, MFSEs can contribute to solving social problems.
