I think some information is often a mixture of truths and lies which is why I tend to filter out all the major left/right media outlets on my Google News feed. I'm just not interested in playing fact checker for every newspaper because they have some left/right crusader journalist that's willing to die on a hill for a particular current political talking point. If those folks are going to mix lies with the truth then I'm going to take the risk of being an ignorant jerk that says "I don't know, I'll have to read up on it" than be led down a blind alley of someone's ideology masquerading as "the truth." Essentially, the most correct position in the majority of cases to be conscientiously ignorant and open to discussion when it's applicable to your life. Beyond that, be as dumb as the rest of humanity to the ins and outs of any issue if it's not interesting or fun to you.

Edit: also, I think this doesn't apply to matters that are of immediate relevance and consequence. So I do think someone like POTUS or a US Senator should stay informed if possible.
