In peace and science, social justice and medicine, things have never been better.
How do we sound smart with zero effort? Well we don't want to be gullible (everything is good and fair!) so we do the opposite (everything is corrupt and bad!).
I really wish it were more than that.
Saying something like "Amazon is good" well, that's an opinion, definitely grey. Saying "This is exactly 1 inch", well, it probably isn't and the more you care about it's accuracy, the harder it is to measure. Most things are like that. Clear cut at first, and increasingly more difficult the more precise you go. The devil is in the details.
So, yes, if the only options are black and white, the answers are generally easy, you've got a 50% chance of being wrong. As soon as you blur the line, you're basically wrong all the time. The goal is to be less wrong, and to improve, make progress.
