It’s important to make reference here and now, that not all autistic folk are sensitive folk. In certain sections of the Broader Autism Phenotype, certain autistic people are more logical and realistic (rationality and realism) than emotionally centered. When a person is born with a natural preference for logic and realistic reasoning, emotionally based intelligence (EQ) and senstivity may not be a normal occurrence in this population.
However, for the autistic individuals that were formed as part of the sensitive community, just as there isn’t one universal cause for Autism, there isn’t one cause for sensitivity.
Some brain types are literally wired on the conscious level with differences that create a sensitive nature. For this group of Highly Sensitive People (HSP), some of the differences include a wiring difference in the amygdala area and others around it.
In others, the causes for a sensitive nature cannot be detected on an fMRI scan, because the source for their HSP nature isn’t caused by neurological differences in the conscious level of the brain. It’s buried deep within a level of their nature they can only sense through the messages from their heart.
Each one exists as a sensitive person for different reasons.
