If you encourage your neighbors to vote, local politicians will pay more attention to your area. I doubt it goes much broader than that.
You could say the same about not voting.
In the context of the article and the point OP made it’s working out great not being informed or voting. At least for me. I don’t stress or get worked up by stuff. I feel like I’m a lot happier these days. Deliberate ignorance is not for everyone but it does work well for me.
Well, if you can say the same thing about voting and not voting, then it makes not much of a difference either way...
