CORE DEFINITION

The Japanese term for "evaporating from society." It refers to people who, to escape debt, failed marriages, or shame, with the help of specialized companies, completely sever all social ties, assume new identities, and move to another place to start a new life.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

An extreme reset mechanism. It reminds us that when social pressure becomes unbearable, "disappearing" is a survival strategy that, though drastic, exists. Social death is sometimes the price of physical survival.

anchor

Anchor fast decisions

The process by which molecules at the surface of a liquid gain sufficient kinetic energy to detach from the liquid phase and enter the gas phase, influenced by temperature, surface area, humidity, and wind speed. It is a phase change and mass transfer phenomenon.

Second Law of Thermodynamics

The second law of thermodynamics is one of the four fundamental laws of thermodynamics, stating the irreversibility of thermodynamic processes—isolated systems spontaneously evolve toward thermodynamic equilibrium, the state of maximum entropy. Similarly, a perpetual motion machine of the second kind is impossible. The history of this law can be traced back to Nicolas Carnot's research on the efficiency of heat engines and his Carnot theorem proposed in 1824.

Coherence

In physics, coherence (also called phase coherence) states the possibility of interference between two waves. Two monochromatic beams from the same single light source always interfere with each other. If two wave sources have the same frequency and waveform, they are coherent. The physical sources of coherent waves are not strictly monochromatic; they may be partially coherent. However, beams from different physical sources are mutually incoherent.

The Great Filter

The Great Filter theory is a hypothesis that attempts to explain the Fermi Paradox. It posits that in the development of life, from its early origins to the highest level on the Kardashev scale (Type III, capable of utilizing all resources of its galaxy), there exist certain developmental barriers (referred to as 'filters'). Consequently, extraterrestrial life detectable by humans is extremely rare. The concept was proposed by Robin Hanson: the absence of any extraterrestrial civilizations in the observable universe implies that the emergence of advanced intelligent life is very unlikely. This observation is conceptualized as the 'Great Filter'.
