“…This implies an adaptation to the secularization trend of Western European societies when immigrants are exposed to alternative and non‐religious values and worldviews (Diehl and Koenig, ; Güngör et al., ; van Tubergen, ). Accordingly, some empirical studies find a decline in religiosity in the second generation and with an increasing length of stay (Bisin et al., ; Connor, ; Eilers et al., ; Güveli and Platt, ; Maliepaard et al., ; Phalet and ter Wal, ; Smits et al., ; van Tubergen, ), as well as over time (Diehl and Schnell, ; Phalet et al., ). Implicitly assumed is that mere exposure to the host society and increasing contact with members of the native population enhance familiarity with the mainstream culture, eventually leading to assimilation in different life domains.…”
