My guess why, also based on no data whatsoever:<p>1. Older people grew up in an era where news sources were trusted as platforms that reported facts. But now most news sources are optimized for user engagement, which are most effective when delivering divisiveness, outrage, and fear mongering.<p>2. Older people have more time to watch the news, and thus the effects of prolonged exposure to such negativity has more of a chance to shape their views.<p>But who knows what the real truth is without more research?
