Reading news is pointless and you shouldn't do it.
I've seen studies on this before. But never heard the argument quite so coherently stated as in this post from Farnam Street.
“Being well informed isn’t regurgitating the opinion of some twenty-two-year-old with no life experience telling me what to think or how outraged to be. Your first thought on something is usually not yours but someone else’s. When all you do is consume, you are not only letting someone else hijack and direct your attention; you are also letting them think for you.”
