Primal world beliefs ("primals") capture understanding of general characteristics of the world, such as whether the world is Good and Enticing. Children (N = 1215, 50% girls), mothers, and fathers from Colombia, Italy, Jordan, Kenya, Philippines, Sweden, Thailand, and United States reported neighborhood danger, socioeconomic status, parental warmth, harsh parenting, psychological control, and autonomy granting from ages 8 to 16 years. At age 22 years, original child participants reported their primal world beliefs. Parental warmth during childhood and adolescence significantly predicted Good, Safe, and Enticing world beliefs, but other experiences were only weakly related to primals. We did not find that primals are strongly related to intuitive aspects of the materiality of childhood experiences, which suggests future directions for understanding the origins of primals.
