“…More specifically, after 40 years of research focussing on personal attitudes toward multiculturalism and assimilation, there is now strong evidence showing the importance of distinguishing between the perceived cultural or group norms, that is the perceived level of support in a country for a given national integration policy, from personal attitudes, that is the extent to which individuals personally support these norms (see Guimond, de la Sablonnière, & Nugier, 2014;Guimond, Streith, & Roebroeck, 2015;Pelletier-Dumas, de la Sablonnière, & Guimond, 2017). Whereas national integration policies can have little direct impact on personal attitudes (Van de Vijver, Breugelmans, & Schalk-Soekar, 2008), they can have a strong impact on the perceived cultural norms, and it is through these norms that they can shape how the population feels, thinks, and behaves toward immigrants (Anier, Badea, Berthon, & Guimond, 2018;Guimond et al, 2013;Schlueter et al, 2013). However, it is unknown how the perceived cultural norms associated with national integration policies develop and why some norms have more of an impact than others.…”
