STOCHASTIC EFFECTS 1)2)
The possible effects that can be produced by random perturbations in a system.
These effects can be either insignificant, or very serious, as explained by P.M. ALLEN et al:"Instead of stochastic effects being simply minor irritations for the modeller, producing a deviation from the "mean" of his predictions, we see that in fact they (may) drive the system from one state of organization to another – they are the vital force of evolutionary change" (1984, p.248).
The "vital force" of change seems in fact to be energy overload, while in the far-from-equilibrium situations thus produced, a stochastic event can act as an trigger orienting the change.
