TikTok has announced that its STEM feed will now be available to all users in the U.S., U.K., and Ireland by default, shifting from its previous restriction to users under 18. This move is intended to enhance the discovery of educational content on the platform. Users can opt out of the STEM feed via the app’s settings. The initiative stems from criticism regarding TikTok’s impact on mental health, particularly among teens. Since its launch, the STEM feed has led to an 18% increase in STEM content and 200 million views on related videos, signaling a shift toward a more informative platform.
