Well, the world is a complicated place and we have limited working memory, so our models can only be so good without the use of external tools. In practice, I think looking for reasons why something is true, then looking for reasons why it isn’t true, has been a useful rationality technique for me. Maybe because I’m more motivated to think of creative, sometimes-valid arguments when I’m rationalizing one way or the other.
