When thinking, rationality means the methods that lead you towards true statements and away from false ones. When acting, rationality means using rational thought to determine what will produce the best outcome (for some criteria), and doing that.
Conversely, irrationality means using methods of thought which you know or ought to know will lead you to false conclusions, failing to give an action thought proportional to its importance and complexity, or figuring out what action will produce the best outcome but not doing it.

“rationality means the methods that lead you towards true statements and away from false ones.”
No, it means consciously choosing the methods that your explicit mental model of reality indicates should produce true statements.
Your definition refers to objective properties of methods and statements that we don’t actually know.
