<p>The uncertainty regarding access to financial resources, subsistence, or even care during childhood (i.e., childhood environmental unpredictability) influences individuals' behavior and decisions in adulthood. This study explored the impact of perceiving different patterns of childhood environmental unpredictability experienced on status motivation in a Brazilian sample. 439 participants provided information about their social class, status motivation, and perception of the childhood environmental unpredictability through online questionnaires. The results showed that adult individuals with low status motivation were those who experienced childhood environmental unpredictability in family support and meal routines, even if they did not experience financial unpredictability. On the other hand, adult individuals with high status motivation were those who did not experience childhood environmental unpredictability in family support and meal routines, even if they experienced uncertainties regarding access to financial resources. Our findings suggest that family support and meal routines during childhood have a significant influence on how adult individuals acquire, develop, and accumulate skills, knowledge, and competencies valuable for standing out in their social group—seeking status. The results also highlight the importance of early interventions and public policies that promote predictable and supportive environments for children. Initiatives such as parenting programs, food security policies, and community support for caregivers may contribute to fostering adaptive motivational patterns and social investment in adulthood. This work highlights the connection between childhood experiences of precarious socio-environmental conditions and inclinations toward status seeking in adulthood, signaling the complexity of developmental factors in the manifestation of human behavior.</p>
