TikTok’s grip on our collective attention spans might be even more dangerous than we thought. According to the company’s own research, users may only need to watch 260 videos before developing addictive behaviors. The findings also link excessive use to a series of mental health issues, including impaired memory, loss of analytical skills, diminished empathy, and heightened anxiety.

Lawsuits have filed against TikTok, accusing the platform of falsely advertising its algorithm and putting children at risk. The lawsuits claim that the company prioritized user engagement over the well-being of its younger audience.

The unredacted documents suggest that TikTok struggled to balance safety with its desire to keep users engaged. While the platform implemented features like screen time alerts and usage limits, its own data shows these measures had little effect. In fact, the screen time limit feature reduced usage by only 1.5 minutes per day, raising concerns that such interventions were more about optics than actual safety.

The platform’s effect on body image also emerged as a significant issue. The documents allege that TikTok’s algorithm has a bias toward promoting content from conventionally attractive users. Meanwhile, harmful content—such as videos related to eating disorders and suicidal ideation—often slipped through moderation and became part of algorithm-driven “bubbles” that young users were frequently exposed to.

In a statement to NPR, a TikTok spokesperson responded to the allegations, saying, “We have robust safeguards in place, which include proactively removing suspected underage users, and we have voluntarily launched safety features like default screen time limits, family pairing, and privacy settings for minors under 16.”
