In psychology, social context is how the social or physical environment affects how a person will react. Social context is also known as milieu, and can strongly influence a way a person perceives an event or object.
Think of someone putting a platter of freshly grilled organs in front of you. Where I now live, this is a somewhat common dish. People grew up with that food being a delicacy. But I wouldn’t touch that with your hand, reader. Local people around me, on the other hand, eat that up like there’s no tomorrow and say it’s delicious.
Their social context for grilled organ meat is clearly different than my own.
