CORE DEFINITION

“Birds of a feather flock together.” In social networks, similar people (age, race, beliefs, occupation) tend to connect with each other. This is the natural gravity of social structure formation. -

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

The physical basis of information cocoons. Because of homophily, your social circle is inevitably biased. You think the world is like this, but in fact, it is only people like you who are like this. To gain new knowledge or heterogeneous information, you must operate "against homophily"—actively connect with people who are completely different from you (weak ties).

Homophily refers to the degree of consistency of a group or sample on key attributes; homogeneous samples facilitate internal comparison, while heterogeneous ones require stratification.

Demographic Transition

Demographic transition refers to the phenomenon in which a country or region transitions from a pre-industrial economic system to an industrialized economic system, often accompanied by a transition from high birth and death rates to low birth and death rates. This theory was proposed by American demographer Warren Thompson in 1929, who observed and studied the changes or transitions in birth and death rates in industrialized societies over the past two centuries.
