Whenever someone points out that we are ignorant in some form or another, it’s human nature to get defensive or angry. That’s a shame, because rational ignorance is part of life. It’s what should be prompting us to improve our understanding or to seek out greater truth. Nowhere is rational ignorance more noticeable than at the voting booth. Uninformed voters can cause tremendous damage when they lend their support to people and policies they don’t understand. It’s not a matter of purely ideological or political disagreement. Effective citizenship goes well beyond simply casting a vote on election day.
