What is a normal family? Common assumptions and current evidence

Area of Science:

• Social Sciences
• Applied Human Sciences
• Psychology
• Sociology
• Anthropology
• History

Background:

• The traditional nuclear family (first-marriage couple with biological children, defined gender roles) has been assumed as the norm in social sciences.
• This structure was often considered both most common and best-functioning in professional literature.

Purpose of the Study:

• To challenge the assumption that the traditional nuclear family is the most natural, common, or healthy family structure.
• To highlight the implications of idealizing the traditional nuclear family on research, practice, and policy.
• To advocate for recognizing the traditional nuclear family as a culturally and historically specific construct.

Main Methods:

• Review of current psychological, sociological, anthropological, and historical studies.
• Analysis of the impact of the traditional nuclear family ideal on scientific and social practices.

Main Results:

• Empirical evidence does not support the traditional nuclear family as the most natural, common, or healthy arrangement.
• The idealization of this structure has led to the invisibility or pathologization of diverse family forms.
• Scientists and practitioners have been slow to identify pathology within traditional nuclear families.

Conclusions:

• The traditional nuclear family is a culturally and historically specific construct, not a universal or inherently superior model.
• Contemporary social and applied human sciences need to acknowledge and research the wide variations in family structures.
• A new research agenda is needed to account for family diversity across time, place, social class, ethnicity, and culture.
