An ensemble of biological parts are necessary to be expressed and put together just right so that a person's individual place on any particular Spectrum Personality Filter is determined.

The example of a car and the multiple parts that together are responsible for its features is very useful.

For the purposes of illustration, a car's behavior is a nearly perfect analogy for a human's behavior. How so? A car has an organic basis as well. All that it Is is grounded within the physical world. Not one thing that it is, not one way that it behaves has any other explanation than can be provided from within the realm of physics, chemistry, material sciences, etc.

Well, how does it behave? A car has speed. (Some cars are faster, others slower.) A car has acceleration. (Some get to speed more quickly, others more slowly.) A car has cornering abilities, it has stopping abilities, it has steering responsiveness, it uses its fuel with a certain efficiency. These are all car behaviors, and there are quite a bit more.

And yet, there is no "part" for "speed." None for "acceleration. On so on. Each of these attributes or car behaviors is the result of many different parts cooperating together. For example, its stopping ability is the result of its brakes, tires, anti-lock braking system (ABS), road conditions, and even the action of its driver. For a car, there is no "stopping" gene.

Sometimes one of these components might degrade, go bad, or have been missing altogether. For example, the car might find itself without a driver at some moment while it is still rolling. In this case, it will be unable to stop in the same precise manner that we had become accustomed to. Certainly, an analyst would say, "That driver was an important component for 'stopping'." That would be accurate. What would not be accurate is if the analyst were to assert, "We have found the part solely required for 'stopping'!"

It will be that way with human behavior and perception for the most part. There is not likely to be any specific "gene" for any specific "'XXX' Spectrum Personality Filter", or what we will often refer to in shorthand as "XXX." Rather, XXX is observed when a number of other genes for multiple other biological functions cooperate together in a particular way, and "dial themselves up" in a particular way as well. If one "part" ceases to be dialed up or pieced together in the way that cooperatively gives rise to XXX, then we will not see the XXX phenotype any longer, or we may see it reduced or increased.

Most of the traits for behavior and perception will be found to be "expressed" by a similar mechanism of action - meaning there is not one biological gene that gives rise to the trait, but rather multiple genes interacting cooperatively as an ensemble that give rise to the trait.

Just like a car. There is no gene for "speed." But Speed will be observed when engine, fuel, ignition, brakes, driver, and terrain cooperate with each other in a certain way. And yet, while there is no gene for speed, most certainly the Speed and Acceleration and Handling that we observe with a Corvette, for example, will be much different than what we will observe in a Beetle. And repeatedly and predictably so.

Because the components are different between the two cars, and they are dialed up and arranged differently as well. The explanation for their differences in performance is organic.
