For a long time I thought many politicians were "dumb" based on their public comments, propelled only by their connections. Now, when I look up some politicians who's spouting objectively false / misleading statements and find they've graduated a top-tier university and have a JD I realize these are not intellectually stupid people. They're skilled in their field, have drive, and less empathy/morals than others.
Now, I watch these "dumb" people more closely.
