You can't, all you can do is be open and humble when you're wrong. When you say something that turns out to be incorrect, don't get defensive or extremely, apologetic - a simple "Oh, really. Interesting" will suffice and move on. It can be difficult if the other person is extremely insecure and is trying to shove it in your face that you were wrong, but so long as you yourself are secure then you will be ok with being wrong. The smartest people I know are also the most humble because they are open to new ideas and willing to be wrong.
