Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that TikTok's recommendation algorithm worsens the mental health of its users?

Unclear. Several sources partially support the claim: a systematic review links excessive TikTok engagement to increased anxiety, depression and stress, an audit shows engagement saturates feeds with mental health content, and a narrative review finds the algorithm disproportionately delivers eating-disorder material to vulnerable users. None of these establishes that the recommendation algorithm itself causes worsened mental health, and the review itself notes causality is undetermined.
