“I was wrong” is hard to say. Practice it on small stuff so it’s ready for the big stuff.

Admitting error has a physical component, because the sentence genuinely catches in your throat the first several times. If you have only ever avoided it, the moment you really need it will be the moment you are least able to produce it, and you will reach for something hedged instead. Using it on trivia builds the reflex cheaply. Nothing is at stake when you were wrong about a scoreline.

Say it this week about something that does not matter: a date, a fact, a name you misremembered. Use the plain words rather than softening them into perhaps. Note how fast the conversation moves on afterwards.
