I noticed that in families with A- trait, some individuals were sweet and soft-spoken and greatly loved. They were often great students, idealistic, intellectual etc.
Here's an example in the Bush family ( I think):
Since I think the COMT val/met nuclear polymorphism (a certain well-studied single nucleotide mutation in the catechol-O-methyltransferase gene controlling largely the amount of dopamine extant in the brain cortex especially) is likely a major cause of A- trait, I think that it is also a major cause of the quietness in the N type that we call "low temperament" N. Remember that the difference would be seen in someone like Marilyn Monroe or Natalie Wood as low temperament N vs say Sarah Jessica Parker as high temperament N.
So when I say N COMT met, I mean "low temperament N"
You may notice that in a later post I pointed out that I though most individuals with schizophrenia in sanguine habitancies would be low temperament N (could be low temperament NP) as their baseline personality type. That does not mean that all low temperament N types are schizophrenic, but that most schizophrenic in sanguine habitancies are low temperament N types. Autism in these habitancies would be similar except that many more would be NA=/NPA=/NP, etc.
Low temperament N types would show up often as criminals ar times but just as often as presidents, movie stars and very well liked neighbors and friends
