Psychological obstacles to multiculturalism: how stereotypes and mechanisms of defence may cause adverse behaviours to multiculturalism

Migration flows are part of human history. The process of globalization, if on the one hand, it seems to favour the movement of human beings, on the other hand, it is creating the conditions for the recovery of migratory flows, especially within some areas of the world and, in part, directed towards advanced developing countries. This creates problems of acceptance on the part of the host with respect to the customs and habits of the guest. Resistance to reception, used for political ends by populist parties, has deep roots that have to do with psychological and social factors: defence mechanisms, stereotypes and prejudices. The article stresses the importance of training in overcoming these obstacles to building a society that is first multicultural and then intercultural.
