Final answer:
It is true that similarity plays a key role in the formation and maintenance of friendships. We tend to form relationships with individuals who are similar to us, as it makes interaction more comfortable, leading to stronger bonds. Proximity also influences relationship formation by increasing our interactions with potential friends or partners.
Step-by-step explanation:
It is true that friends often have a number of characteristics in common. The similarity observed both in friendship formation and maintenance is a well-documented phenomenon. It has been established through research that we are naturally inclined to form connections with individuals who share our backgrounds, attitudes, and lifestyles—this concept is known as homophily. You are more inclined to form a friendship or romantic relationship with someone similar to you because it facilitates an easier and smoother interaction. When you share common interests, such as musical tastes, hobbies, or food preferences, spending time together becomes pleasing and effortless, thereby strengthening the bond.
Proximity is another influential factor in forming relationships, as suggested by research. We tend to build stronger ties with people we see regularly, like those who live in the same residence or neighborhood. This regular contact increases the opportunity for interaction and the likelihood of a relationship forming. However, it's not just proximity; the similarity in our values, beliefs, and interests plays a pivotal role in bringing us closer and is essential for the maintenance of these relationships.
