Social networks create cliques online primarily by connecting you with people you already know and like. This connection is often facilitated through algorithms that prioritize content from friends, family, and acquaintances, reinforcing existing relationships and shared interests. Additionally, they can connect you with people who have similar opinions, which helps solidify these cliques.
While social networks may expose users to differing views or new ideas, their design tends to favor user engagement and interactions that align with personal preferences and existing social circles, often leading to echo chambers rather than diverse interactions. Encouraging users to block people they don't know or like further contributes to the formation of cliques by limiting exposure to contrasting opinions.
In summary, the primary mechanism for creating cliques on social networks is through connections with familiar individuals and shared opinions.
