Nurture
Social scientists would argue that our reality and life outcomes in general are shaped by social forces or are socially constructed rather than biologically determined.
According to this perspective, our reality is shaped by the socialization we receive from our parents and teachers, the kind and quality of education we receive, our socioeconomic status, our peer groups, etc. Inborn biological factors (our nature) do not play as big a role in shaping our reality and outcomes.
