At least for me, the main issue I have is that many people I interact with use "gotchas" to try to "prove" that I'm wrong in conversations/arguments, which eliminate significant amounts of context, nuance, or stretch the bounds of reality. Alternatively, many situations involve people, and people don't act rationally, so a model which assumes rational actors will often be violated by the behavior of others in practice, which doesn't necessarily mean that the model is wrong or the expected behavior wouldn't have been more optimal, it's simply not what the person chose to do.
When there is sufficient evidence based in reality that my model or my understanding is incorrect, I freely admit to it and work to get even more information so I can update my model of the world and improve my understanding. I am rarely incorrect, because I am nearly obsessive about learning more and more information about the world around me. Sometimes when I am legitimately wrong, it is because I have forgotten a detail and when corrected admit to this, but it is unsatisfactory for the other person because they are expecting me to completely change my entire world view rather than simply saying "You're right, I forgot about that, but did know that, so yes ... X".
