The correct interpretation of what genetic predisposition reveals demonstrates that biology acts as a fundamental precursor: the individual is, in essence, what their genetics defines. Although environmental and educational factors interfere in human development, this influence occurs only within the limits established by genetic predisposition.
If environmental factors influence behavior, they do so by acting on a structure of which genetics is the precursor. This means that all education received shapes the individual, but it is the genes that determine how this shaping occurs and how far it can go. However significant external stimuli may be in a person’s life, they will always manifest personality and behavioral traits stemming from their biological inheritance.
Genetics is, therefore, a priori. Any act or behavior manifested in response to the environment invariably refers to a latent genetic behavioral possibility, as this functions as the innate precursor of all action.
Hypothetical Example: Phenotypic Resonance
To illustrate scientifically, consider a hypothetical scenario involving neurodivergence or the so-called “Extended Autism Phenotype.” Imagine a mentor (father figure or educator) who possesses undiagnosed autistic traits, that is, individuals whose cognitive mechanisms compensate for classic deficits, keeping them functional but operating with a specific neurological logic.
If a young person under the tutelage of this mentor reports that the education received was extremely meaningful and resonated deeply with them, this is not only due to the quality of the environmental instruction. It is plausible to assert that this connection occurs because the young person shares a similar genetic predisposition. The learner’s brain functions analogously to that of the mentor.
Identification occurs through the similarity of the biological condition. It is the shared phenotype that allows the education to “fit.” Conversely, in the same environment, another individual may not identify with or absorb the same education in the same way. The reason for this discrepancy is not the environment (which was the same), but the absence of genetic compatibility. Where there is no biological mirroring, environmental influence loses strength in the face of genetic determination.
