In an Internet-based Dutch ‘Millennium Survey’ large differences between open-ended and closed questions were observed with respect to tapping attitudes towards future developments in Dutch society. The answers to the closed questions pictured a rather stable optimistic public opinion climate. Yet, when the open-ended questions in the Millennium Survey were analyzed, the story was impressively different: large shares of respondents extensively commented on future trends and displayed their fears for the future. Much of those fears related to foreigners and the impact of the Islam. The following years in the Netherlands (and elsewhere) were very turbulent, politically, socially, and culturally. Much of the turmoil was directly related to the fear-evoking, and at that time strongly controversial, issues already tapped in the open-ended module of our survey. This chapter displays the discrepancies between closed- and open-ended questions in the Internet-based survey, draws some methodological conclusions, and reflects on necessary augmentations in Internet survey research if one indeed aims to more closely reflect the true controversies in public opinion.
