Plane Priority

So how do these 3 planes interact when all 3 are used at different times?

The plane which is being used, would depend on the circumstances of the external variables, and the condition of the individual.

Plane 1, instinct would still always cause the same reaction based on the specific factors which trigger it, unless the reaction is overridden. Since Planes 2 and 3 are further developed for more accurate circumstances, if those circumstances arise, it would statistically be more beneficial for the animal to use those higher planes of subconscious or conscious thought, rather than instinct, if they conflict.

Plane 2 would similarly be the cause of reaction based on certain occurring factors. 1 difference from instinct, is the reactions would change and be adaptable based on circumstances. The reaction would differ based on sensory input and feedback triggers (such as emotions, pain) which create memories, then reference those memories for the most beneficial reaction in future, similar circumstances.

Just as Plane 2 would override Plane 1, based on probability of beneficial outcome from more accurate circumstance analysis, so too would Plane 3 override Plane 2. Ideally, Plane 3 should have highest priority of control, since consciousness is able to more accurately analyse circumstances, and more accurately react beneficially.

But, considering the speed at which each method of reaction occurs, some circumstances may actually give an advantage to a lower Plane over a higher one. With Plane 1 being the fastest reaction, involving much fewer operations of function, if time is very urgent, instinct might be the best method of reaction. Similarly, Plane 2 is a faster reaction than 3, with fewer operations, and would be the optimum method of reaction, if time of reaction is too pressing for conscious thought, but not so pressing that quick instinct is required.

The most advantageous Plane for the brain to use, seems that it would be quite relevant to the environment and circumstances. The more time pressing the environment is, with fewer variations of circumstances, the more the lower Planes would prove advantageous. Whereas the more complex the environment, with more variables, and perhaps the more secure the environment, the more the higher Planes would prove advantageous.

So without a demand by the environment, for accurate analysis of circumstances, higher Planes would likely not develop through natural selection. But if the demand occurs, and the development occurs, the capability of higher Planes could prove to be extremely advantageous, especially if a hybrid of reaction methods are used. If the species with the higher Plane capability, also uses the lower Planes in certain circumstances where the quickness is beneficial, then there could be little to no disadvantage to the additional brain Plane capability (in spite of a potential disadvantage, if used at the wrong time).

If a species (such as apes? :) were to develop a monopoly on a higher plane of reaction method (such as consciousness?), they could prove to be far superior in dominating the environment. And if that species used the advantages of accurate outcome prediction, to make their environment more secure (such as use of tools & coordinated cooperation?), their advantage would only increase, with a lack of urgency and therein allowance of time for accurate decisions. And if they were to continue to increase use of tools, and coordination by communication, their environment would become more complex as well, increasing the quantity of variables (such as information shared by language, + technology?), and even more-so increasing their advantage of accuracy of analysis.

Though, if a retaining use of Planes 2 and 1 occurs, during development of Plane 3, some of the specimens with a reduced use of Plane 3, might inaccurately use some of those tools and technology (which were created and shared by co-operation) as a result of Planes 1 and 2 triggering their use. This could potentially cause collateral damage (such as nearly all problems in the world cause by humans?), using tools with increased risk capabilities, by those with a lack of accurate analysis, from a lack of use of Plane 3.
