Talk to someone you disagree with long enough to explain their view back to them. That’s learning, not losing.

Being able to state somebody’s position so they recognise it is a hard skill, and it is not the same as agreeing. Until you can do it, you are arguing with your own summary of them, which is usually a weaker version than the real thing. The effort also tends to surface the part of their view that has something in it.

Take a disagreement you are already in and say their case back until they tell you it is right. Ask whether you have it before you answer it. You are allowed to still disagree afterwards.
