Why siblings who grow up together can remember very different childhoods — and what it means for Thai families
Hearing relatives describe the same childhood in sharply different ways is common — one brother remembers a warm, adventurous upbringing while a sister recalls strict rules and missed opportunities. New popular coverage and decades of behavioural-genetics research say this is not just family myth-making but a predictable result of how children experience the world differently even under one roof. A recent explainer in HuffPost lays out the clinical and practical reasons siblings can have vastly different childhoods, from changing family circumstances and parental moods to birth order and personality differences HuffPost. That observation aligns with long-standing scientific work on the “nonshared environment” — the environmental influences that siblings do not share — and has direct implications for Thai families navigating shrinking household sizes, rapid economic change and shifting gender and filial expectations.
