The Short Version
The claim captures a real but overstated trend. Peer-reviewed research confirms that Gen Z shows greater openness to AI mental health tools partly due to anonymity and reduced stigma concerns. However, the evidence does not support a broad "preference over human confidants" — surveys show only about a third of teens prefer AI for serious conversations, and just 12% use AI for mental health at all. Additionally, AI platforms themselves carry stigma-amplification and privacy risks that undermine the claim's rationale.
