4 A related study by Michael Sunnafrank (2004) showed that when people first meet, they quickly make predictions about what kind of relationship they will have. Sunnafrank found that these predictions had a strong impact on future relationships. In his study of 164 first-year college students, Sunnafrank found that when students predicted they could be friends, they sat closer together in class and interacted more. As a result, they actually became friends. In other words, they made their predictions come true.
