Final answer:
An average-looking guy is most likely to have a long-lasting relationship with individuals of similar attractiveness due to the matching hypothesis, proximity, and the principle of homophily.
Step-by-step explanation:
According to the research on attraction, an average-looking guy is most likely to establish a long-term relationship with individuals of similar attractiveness. This finding is in line with the matching hypothesis, which posits that people are generally attracted to and engage with others who they perceive as similar in terms of physical attractiveness and social desirability. Furthermore, similarity in background, attitudes, and lifestyle, as well as proximity – the regular contact one has with others – play significant roles in the formation of relationships. This concept of being attracted to those similar to us is known as homophily.
Moreover, while physical attractiveness is an initial factor in attraction, social traits are also deemed attractive, such as warmth and social skills in potential female mates, and achievement and leadership qualities in males. It is important to note that people weigh a potential partner's attractiveness against the likelihood of success with that person, often seeking partners whom they believe they have a chance with, rather than pursuing those perceived as 'out of their league.' The effects of physical attractiveness on relationship-related outcomes have been studied extensively (Hosoda, Stone-Romero, & Coats, 2003).
