Relationship Formation

Whether friendly or romantic in nature, the relationships that people form are significantly impacted by two key factors: proximity and similarity.

With proximity—the physical closeness with another person—both parties can interact more frequently. For example, during the first week of college, a student is more likely to make friends with others who are on their same dorm room floor because they constantly see them. Another reason that proximity leads to liking is the mere exposure effect—the idea that the more someone is exposed to something, the more they tend to like it.

They are also more likely to form friendships with people of similar backgrounds, attitudes, and lifestyle choices—such as both being the youngest sibling and having similar tastes in music.

Being attracted to like-minded individuals is called homophily—an all-encompassing tendency to gravitate towards people like ourselves. While sharing common life situations can strengthen connections, be aware that such affinity can also limit exposure to diversity and engaging with people who are different.
