The TikTok algorithm served to U.S. children is vastly different and can expose them to harmful content promoting dangerous behaviors, inappropriate material, and addictive viewing patterns. Recent demonstrations show that a new account registered as a 15-year-old American girl immediately receives recommendations for dating older men, substance use, and self-harm content -- before the user has even watched their first video. Meanwhile, Chinese youth using Douyin are allegedly served up a much tamer version showing science experiments, educational content, and videos celebrating academic achievement, with mandatory breaks and usage restrictions featuring a “teenage mode” which limits use by children under 14 to 40 minutes a day, making the app unavailable to those users between the hours of 10 p.m. and 6 a.m.
