You are right that constant exposure to negative headlines can seriously affect mental health, and many studies link it to increased stress and hopelessness. I think the failure of a “good news only” station does not necessarily mean people prefer bad news, it may just show that audiences want balanced, realistic reporting. News that feels overly positive can come across as incomplete or disconnected from real life. Perhaps what people truly want is not only good news, but honest coverage that includes not only problems but meaningful solutions.
