The study looked at how being open to other cultures and groups affects people's personalities, beliefs, and interactions. They found that people who are more open to other cultures tend to be more outgoing, agreeable, and open-minded. They are also less likely to have authoritarian or nationalist views. People who are open to other cultures have better relationships with different groups and are less prejudiced. The researchers used a special scale to measure this openness and found that positive interactions with other groups can increase this openness over time.
