CORE DEFINITION

A biological organism occasionally reappears with ancestral traits (e.g., humans with tails). In sociology, it refers to society regressing to primitive states such as tribalism or violent resolution under the collapse of modern civilization or under high pressure.###

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

The fragility of civilization. Do not assume civilization is irreversible. In extreme crises (e.g., war, pandemics), humans quickly "atavize." When predicting behavior, consider the resurgence of this primitive undercurrent.

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.
