Overview

Dr. Elizabeth Letourneau and Luke Malone discuss their book 'One in Five,' revealing child sexual abuse as a major public health crisis affecting 20% of children. They explore prevention strategies, the complexity of perpetration (including that 70% of cases involve other minors), and challenge common misconceptions about who commits abuse and how it can be prevented through public health approaches rather than purely criminal justice responses.

Origins of a Groundbreaking Collaboration

Luke Malone, an Emmy-nominated journalist, initially reached out to Dr. Letourneau reluctantly in 2012-2013 to discuss a group of young, self-identified non-offending pedophiles he was profiling. Despite Elizabeth's initial hesitation due to illness, this meeting sparked a transformative partnership. Elizabeth had spent 38 years working on child sexual abuse prevention, starting almost by accident in grad school when assigned a paper on pedophilia, while Luke had been investigating this topic to understand what happens before someone becomes an offender like Jerry Sandusky.

  • Luke was profiling young self-identified non-offending pedophiles (ages 17-20) who formed support groups because no help existed for them
  • Elizabeth founded the Moore Center for Prevention of Child Sexual Abuse at Johns Hopkins
  • Elizabeth has dedicated 38 years to child sexual abuse prevention, starting from a random grad school assignment
  • Luke's thesis evolved into 'Tarred and Feathered,' a widely recognized podcast episode still discussed 12 years later
" I literally went and found a colleague who had a couch. He was like my one psychiatrist colleague. So, of course, he had a couch in his office to lay down. But he was coming from New York to Baltimore and I didn't want to disappoint, but I was legit ill. "
" Jerry wasn't born like a seven-year-old child molester. I wonder what happened before then to get here. "

The Staggering Scale of Child Sexual Abuse

One in five children experience some form of sexual abuse or attempted abuse, online or offline—a statistic based on self-reporting rather than official reports, since 80% goes unreported. Dr. Finkelhor's research shows this number has actually declined about 60% since the early 1990s, though it remains devastatingly common. The economic cost exceeds $9.3 billion annually, with consequences ranging from PTSD and addiction to physical health problems like cancer and cardiovascular disease.

  • One in five children experience sexual abuse or attempted abuse, combining online and offline victimization
  • 80% of child sexual abuse goes unreported, making self-report surveys more accurate than official statistics
  • Child sexual abuse declined about 60% from early 1990s to present, attributed to bringing the issue out of the shadows
  • Survivors face elevated risks for addiction, PTSD, cancer, hypertension, lower academic achievement, and future victimization
  • The economic impact of child sexual abuse costs the US economy $9.3 billion annually
" We're spending $5.8 billion a year to incarcerate pedophiles...and $3 million is spent to prevent it by the government. "
