Studying abroad provides benefits of improved multicultural communication abilities and contributing to collective knowledge. It allows students to learn languages more effectively within their cultural contexts, developing understanding of foreign cultures that enhances conversation quality. Studying abroad also enhances collective intelligence by adding diversity when students from different backgrounds share opinions and experiences, recognizing differences in desirable ways and spreading this intelligence further. If collective intelligence incorporates cultural and political diversity, it could facilitate more cooperative international negotiations and progress the world in a more peaceful direction.
