LOS ANGELES—In the third week of a historical jury trial considering whether social media companies have engineered their platforms to addict young people despite knowing the potential harms, attorneys sparred over what a young plaintiff’s therapy records might reveal about her social media use and mental health.
So far, the jury has heard theoretical arguments and seen forensic evidence, in the form of internal documents, largely centered on what the companies knew and when, and whether their actions, or lack thereof, constitute a “willful and conscious disregard for safety.”
