HN itself is something of an echo chamber, there are not many differing viewpoints held in high esteem here. So it's not always just when looking for information, but the fact that we try to find others who think like we do when actually looking for rest and entertainment. Your social group ends up shielding you from other viewpoints because that is the easier way to exist.

"...when I search for something I look for information..."

The problem is, to paraphrase someone I generally disagree with, not in what you know that you don't know, but rather in what you don't know that you don't know.

To look for information, you have to know it exists; you're less likely to know to look for something if it never impinges on your bubble.

Isn't that what I do "partially" with searching, though? I am looking for something I don't necessarily know ahead of time.

The stuff I don't know I don't know is exactly that which is most valuable to broaden my horizon.

All television news networks and programs exist to sell advertising, and compete for viewers by picking sensational stories, dramatizing the reporting, and reacting to ratings.

Not sure why your comment was down voted. You are correct. The "news" are reported such that you agree with them and your thus more likely to stay on the channel.
