INFOGRAPHIC: Disagreement is a far more common form of response to statements and arguments. Agreeing tends to motivate people less than disagreeing; when you agree there’s less to say. When we disagree, we should be careful to do it well. Most of us can tell the difference between crude name-calling and a carefully reasoned refutation, but it would help to put labels on the intermediate stages. Here’s an outline for a disagreement hierarchy based on 2 elements: the quality of the statement(s) used and the underlying emotion that accompanies the disagreement.
