There may be a cultural gap between nations as much as between individuals and groups. With individuals, the cultural gap may be a matter of education, family background, inherent intelligence or a matter of ethnic origin. The gap between different ethnic groups is aggravated by discrimination, prejudice, segregation, and economic and social disparities. Leaders or representatives of governments may personally surmount cultural gaps in international organizations or meetings and may be able to freely communicate as well as to understand, in processes of dialogue, deliberation, negotiation and agreements. However, their constituencies at home, the great masses of people to whom they are responsible, having little foreign contact, are subject to insularity and narrower views. This creates a great tension for leaders caught by the pressures of the world to assure that their nations play an active role, and pulled on the other side by conservative national feelings that wish little cultural change and minimal foreign influence.
