Elastic instinct can make animals for the changed things to adjust their instinctive behavior, make it easy to adapt to changes in the environment, thus than rigid instinct has more flexibility and purpose, and the body through the conditioning can not before the arrival of the stimulus itself accordingly reaction, make the body more proactive and initiative. Anyway, elastic instinct is higher biological value of variability of external things more advanced way of ordering reaction, is on the rigid instinct, extension, and the synthesis, make rigid instinct has more purposeful and flexibility The determination of this ratio mainly depends on the supply and demand relationship between the two sides and the competition. In general, the interest rate falls when the supply exceeds demand. Interest rates rise when demand exceeds supply. In addition, law, habit and so on also have a larger role.
