CORE DEFINITION

In evolutionary lineages, species body size tends to increase over time. Because larger body size usually brings competitive advantages (predation, mating). But larger size also means greater vulnerability to extinction during environmental upheavals.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

The temptation and cost of getting bigger. Enterprises and organizations have a natural 'Cope's tendency' to keep growing. But this leads to increased fragility. Must always be wary of this 'grow for the sake of growing' inertia, and proactively maintain moderate scale.

Anchor fast decisions

In evolutionary lineages, species body size tends to increase over time, as larger size brings advantages in predation and mating, but also increases extinction risk during environmental upheavals. Scale expansion and fragility increase simultaneously.

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.
