Most parents assess their own child's risk as low because they mentally screen for the stranger archetype and find it absent from their daily environment. The actual epidemiology — concentrated among family members, coaches, clergy, and other authority figures — is widely known in the abstract but rarely internalized as a personal probability.\n", "kind": "intuition" }, "native": { "display": "~25% of girls and ~5% of boys experience sexual abuse before age 18 (CDC)", "numerator": 148, "denominator": 1000, "unit": "lifetime prevalence before age 18 (combined-sex weighted average)", "population": "US children, CDC retrospective adult surveys and child maltreatment data" }, "normalized": { "lifetime_us_adult": 0.148, "display": "~1 in 7 US children before age 18", "log_value": -0.83, "assumptions": "The CDC reports that at least 1 in 4 girls and 1 in 20 boys experience child sexual abuse in the United States.
