The new study aimed to investigate whether early-life experiences—including economic hardship, dangerous neighborhoods, and various parenting practices—predict primal world beliefs in early adulthood. “We found that parental warmth, which involves parents making their children feel loved and accepted, was related years later to young adults’ belief that the world is safe (rather than dangerous) and enticing (filled with beautiful and wonderful things, rather than dull),” Lansford told PsyPost. Right now, we have a much better understanding of adults’ beliefs about the world than children’s and adolescents’ beliefs about the world.
