The document discusses principles and techniques for improving survey design through "Surveytainment". Surveytainment aims to enhance the survey experience for participants through improved questionnaire design, which leads to better data quality and comparability of results. It presents studies that show offering monetary incentives and designing more appealing surveys can increase participation rates and satisfaction. However, incentives may not be needed if the survey itself is interesting and engaging for participants. The optimal design balances the length of the survey, incentives provided, and making the questions appealing.
