Get curious about why they believe it before you decide why they’re wrong.

Most disagreements get argued against a version of the other position that nobody actually holds. People arrive at their views through experiences you have not had, and the reasoning usually makes sense from where they are standing even when the conclusion does not. Skip that step and your counterargument lands somewhere beside them. You have to know the real shape of it first.

Ask someone to walk you through how they got there before you say anything about whether they are right. Listen for the experience underneath rather than the claim on top. You might still disagree, and now it will be with the thing they believe.
