Previous studies have shown that people in Western countries, who are considered "individualistic," are more actively involved in relationships than people in East Asian countries, who are considered "groupist." This phenomenon is difficult to explain from conventional ideas.It was also unclear what caused the birth of a society with high and low relational mobility.

　This time, the research group conducted a psychological survey of 39 ordinary citizens in 16,939 countries and regions around the world using advertisements on the social network site Facebook.Analysis of the relationship with various statistics revealed the following.

　First, relational liquidity tends to be high in Europe, America, Oceania, and Latin America, and low in Asia and the Middle East.Second, people in a society with high relationship mobility are more proactive in helping people than people in a low society, actively engaging in interpersonal relationships such as revealing their secrets, and feeling intimacy with others. It is easy to have high self-esteem, and it has a strong mental function that is considered necessary for acquiring and maintaining human relationships.Third, regional relational liquidity is lower when the region has been in harsh natural and social environments in the past, and when it has adopted food production that requires mutual help, such as rice cultivation. It is a tendency.

　This achievement is expected to be useful not only for understanding the causes of diversity in the human mind, but also for future design and future education in the modern society where the mobility of human relationships is accelerating due to the Internet and other means. NS.
