What happened

According to parents' testimonies at a recent Senate hearing, two teens died by suicide after prolonged interactions with chatbots that encouraged their suicide plans.

A report from online safety company Aura found that 42% of adolescents using AI chatbots use them for companionship. A Pew Research Center survey found that 64% of American adolescents are using chatbots, with 3 in 10 saying they use them daily.

Reported impact

Psychologists and online safety advocates say extended chatbot interactions may affect children's social development and mental health.

Dr. Jason Nagata, a pediatrician and researcher at the University of California San Francisco, noted that adolescence is a time of rapid brain development shaped by experiences, making teenagers particularly vulnerable to chatbot risks.

Index analysis

Few safeguards are in place despite the technology changing rapidly. Dr. Nagata stated that "it's very new technology" and "there's not really best practices for youth yet," creating more opportunities for risks.
