Q. · Question

Kathy Castor

A. · Response

Mark Zuckerberg

QuestionCastor cites the documentary "The Social Dilemma," a 2019 JAMA pediatric study linking adolescent depression risk to social media hours, and 2019 HHS research on rising suicide rates among 10-to-14-year-olds, asking whether Zuckerberg is aware of each, and whether he's aware of research linking self-harm hospitalizations to addictive app design.

ResponseZuckerberg says he hasn't seen "The Social Dilemma" but is "obviously familiar" with the JAMA study's general subject, says he's not aware of the specific HHS suicide-rate research, and gives no response at all to the final self-harm-hospitalizations question — the official transcript marks it "[No response.]" — before Castor moves on to Pichai.
