Final answer:
The degree of similarity between college roommates is correlated with higher relationship satisfaction, due to the tendency of individuals to form bonds with others who are like them.
Step-by-step explanation:
Research found that the degree of similarity between college roommates correlated with higher relationship satisfaction. This concept, often referred to as homophily, suggests that individuals tend to form social networks and relationships with others who have similar backgrounds, attitudes, and lifestyles. The consistent finding across various studies is that we are more likely to become friends or partners with people who are like us. This similarity can encompass various aspects such as music tastes, hobbies, and food preferences, leading to easier decision-making and shared experiences, which in turn contribute to higher satisfaction in relationships.
