I have been a very strong adherent of this philosophy for over 30 years. There’s an adage, “there’s nothing as worthless as yesterday’s news”. Which led me to wonder, “was it even worth knowing yesterday?” I realized the solution was a low pass filter. I first switched to a seven-page newspaper (CSM) delivered through the mail. I realised the editors had to figure out whether it would still be interesting by the time…
What's interesting about this is you picked: 1. Extremely high quality publications. 2. In a controlled manner. That's not "no news" at all, it's a healthy relationship to quality news.
Clearly there things worth knowing and not all of them were by Aristotle, Bach, Newton or Wittgenstein:-). The low pass filter screens put the froth; the selection of sources, the dross.
Not that I even read every article in The Economist, but I do read about things I wouldn’t notice or bother to were I reading from the firehose.
Side point: great thing about HN is that someone can say “here’s a clarification or contradiction in what you said” and have it often not be hairsplitting, so can spark a conversation rather than shut one down.
