"Religious fundamentalism is not a marginal phenomenon in Western Europe," concluded a December 9, 2013, press release of the Berlin Social Science Center (Wissenschaftszentrum Berlin für Sozialforschung or WZB) with respect to European Muslims in particular. The social survey results from six West European countries supporting WZB's conclusion present troubling questions concerning Muslim immigrant integration into free societies in Europe and beyond.
As a WZB Discussion Paper explained, the WZB-funded Six Country Immigrant Integration Comparative Survey (SCIICS) involved a 2008 "large-scale telephone survey." Respondents were "Turkish origin" and "Moroccan origin" people "who came during the guest-worker era" pre-1975 or their descendants. SCIICS surveyed both groups in Belgium, France, Germany, and the Netherlands, while insignificant Moroccan populations limited the survey to Turkish-descent individuals in Austria and Sweden. SCIICS sought 500 respondents from each group in each country as well as from a control group of non-immigrant descended country citizens, with the exception of Belgium with its "high degree of federalism." Here SCIICS surveyed 300 individuals from each group in both Flanders and Wallonia provinces. Almost 9,000 completed surveys or 3,373 native, 3,344 Turkish, and 2,204 Moroccan origin, resulted.
