The official website of Leiden University in the Netherlands issued an article on December 7，Armin Cuyvers, professor of EU law at the school, combined with social psychology researchers，Conducted research on how to enhance the sense of belonging of bet365 free bets to the EU and the legitimacy of EU regulations。

Kuvis thinks，In addressing major challenges such as wealth inequality and climate change，Cooperation between countries is crucial。But，Because this kind of cooperation may require relevant countries and individuals to make concessions in terms of participation and freedom，So it is often seen as a threat。He cited frictions between bet365 free bets in sensitive areas as an example，Raising the immigration issue has triggered disputes among bet365 free bets on several occasions。The law can serve as a bridge and link between the EU and its member states and between member states，Connect them together，It can also provide basic security guarantees for bet365 free bets and their nationals。For this，It is necessary to improve the acceptance of relevant laws and regulations by the citizens of bet365 free bets and the legitimacy of the EU。

Kuvis and others use mobile laboratories to conduct research work across the Netherlands。In the laboratory，They had participants read two versions of a legal text，Observe participants with instruments，Including their blood pressure、Changes in heart rate, etc.。They found out，Compared with people who have a less strong sense of national identity，People with a strong sense of national identity have a higher degree of agreement with the legitimacy of the bet365 free bets。Only if people see the bet365 free bets as a threat to their country’s independent identity，Only then will the bet365 free bets be deemed illegal。Therefore，bet365 free bets legislators should pay attention to reducing the interference of their regulations on the independent identity of each member state，And provide guarantees for the national identity of nationals of each member state，While ensuring that the relevant text is legally correct，Reducing the psychological discomfort it brings to people。In addition，bet365 free bets law should pay attention to dual identities，That is, while allowing people to identify with their common European identity，Ensuring that people’s identities as nationals of a country are secure and identifiable。

Kurves concluded，Interdisciplinary collaboration requires prior understanding of basic knowledge of other disciplines。In addition，Combining the concepts and research methods bet365 free bets two disciplines，Conduct research by asking and answering specific questions，Can achieve better results。
