I think it is valuable to read a hundred convincingly-written arguments in favor of one point of view, become convinced, and then read a hundred opposing arguments and again become convinced. This maintains my awareness of the fact that I'm a terrible judge of veracity of arguments. Since I want to know what happens in the world, I must be exposed to arguments, so I think it's very important to be viscerally aware that I'm an idiot and should use a lot of care.

As for why I want to know what happens in the world and particularly where I live (i.e. North America), it is because those events affect me. If I were on an information diet, then I would probably miss, for example, the recent passing of S.386 [0] by the US Senate, which is intimately relevant to me as my long-term goal is to immigrate to the US.
