Granovetter's theorem

Granovetter's Theorem, often referred to as the "strength of weak ties," posits that our weaker social connections—those acquaintances we don’t interact with frequently—can be more valuable for spreading information and opportunities than our close friends. This is because weak ties connect us to different social networks, thus providing access to new ideas, resources, and job leads. In a nutshell, maintaining a diverse network of casual contacts can enhance our access to diverse information and opportunities beyond what our close-knit friends can provide.
