Final answer:
In long-term committed relationships, 'Birds of a feather flock together' is generally more true than 'opposites attract'. Research has shown that people are more attracted to similar individuals.
Step-by-step explanation:
The statement 'Birds of a feather flock together' is generally more true than 'opposites attract' in long-term committed relationships. Research has shown that people are more attracted to those who are similar to them in terms of background, attitudes, and lifestyle. This phenomenon is known as homophily, which is the tendency for individuals to form social networks and relationships with others who are similar to them. When two people have shared interests, hobbies, and preferences, it becomes easier for them to connect and spend time together, making it more likely for their relationship to thrive. In contrast, there is no evidence to support the notion that opposites attract. While initially, some differences may attract individuals to each other, long-term compatibility is often higher among individuals who are more similar.
