This newspaper comprehensively reported that Douglas Massey, a professor of bet365 promo codes and public affairs at Princeton University in the United States, recently released the latest research results of his research team on the "Dialogue" website。To explain how individuals adapt to changes in bet365 promo codes diversity，The research team used a multidisciplinary analysis method，Psychology、Combining sociological and evolutionary perspectives，Conducted a large-scale comprehensive study。By comparing 33 from 100 countries around the world.Data analysis of more than 80,000 respondents，Researchers found，Humans initially tend to react negatively when homogeneity is threatened，But in the long run，These negative effects are compensated by the beneficial effects of intergroup contact。

Messi said，Initial negative impact is due to increased religious cultural bet365 promo codes in countries，People trust strangers less。But after 4-8 years，People start interacting with people from different backgrounds，This strengthens their trust in others，Positive impact on their quality of life。Initial negative impact，Completely offset by the positive effects of mixing with members of different groups。This shows that despite initial resistance，But humans can cope with the challenges posed by bet365 promo codes。Also，Experiments also show that，If you only focus on the short term，Possibly an inaccurate pessimistic conclusion about the impact of bet365 promo codes。Increased bet365 promo codes provides members of different groups with mutual contact、Opportunities to understand and cooperate，This is when the positive effects of bet365 promo codes outweigh the initial negative effects。

General theories about human evolution and bet365 promo codes diversity，The human brain has evolved a tendency to protect its own group，Because survival depends on cooperation with members of the group。According to this view，Survival often depends on people's ability to protect their own group from potential threats from other unknown groups，So people are very cautious when coming into contact with unknown groups。This may explain why in communities with more diverse demographic backgrounds，Lower trust and bet365 promo codes cohesion。

Messi thinks，Such a sense of group protection may be incompatible with today's rapidly changing society。Now，People tend to live in mixed communities，Need to be constantly exposed to new cultures、Norms and values。At first glance，Protecting your own group and approaching unknown groups seem to be contradictory。But Messi proposed，Human beings in the process of contact with bet365 promo codes diversity，will take into account these two tendencies at different points in time。Although the tendency to protect one's own group may manifest itself during first contact with an unknown group，But as time goes by，Individuals begin to show mixed tendencies，And benefit from interactions with unknown groups。
