My assumption is that humans rely heavily on an embedded framework of social contracts when engaging in social interactions. This is for sure both biological and cultural in origin.
I'm searching for a word that describes an ability to consciously disconnect the "cognitive auto-pilot" from this framework, to be able to act more professional and pragmatic.
John is very ____, even though he has a close personal relationship with Dave, he has no problems in keeping a strictly professional relationship with him in regards to their joint venture.
(John's personal relationship conflicts with his professional relationship with Dave, but John has the ability to disregard from selected parts of the social framework that he deem unsuitable)
Our accountant Jenny is ____ embodied; even though she was secretly in love with Dan, she had no second thoughts about reporting him to the disciplinary board for his unmotivated spending.
(Jenny's social framework has a lot to say about how she should act towards Dan since she is in love with him, but she has a high ability to disregard the influences from the social framework that conflicts with her professional role.)
The brothers Tony and José grew up together and both joined the Mafia at around the same time. They had a strong brotherly love and always stood up for each other in times of trouble. However, when Big Boss ordered Tony to put a bullet between José's eyes, it was like Tony had never known him and complied without hesitation, even if it greatly saddened him.
The only word that I can think of that relates to the ability to consciously bypass the social framework is sociopath, although this have very negative associations. For example :
a person with a psychopathic personality whose behaviour is antisocial, often criminal, and who lacks a sense of moral responsibility or social conscience.
Are there any neutral but precise words I can use to describe ones ability to consciously distance oneself from influences from the embedded social framework?
I'd consider terms like cold, professional, high integrity as way too general and imprecise here.
