To be fair, on the first one, your son is
only five years old. I don't think there's anyone
that age who doesn't think that they're wrong. There's likely more hope in that case as you have time to make sure that that simply will be just a phase most of us have gone through anyway.
In any case, a lot of these people have issues with pride. They have too much of it, and being seen as wrong or *gasp* admitting
that they might be wrong is like the death knell for them. I've encountered plenty of people who are like this, in real life and online.
Ever been around the person who seems just a little more
critical of you than some others and kind of acts like they are more reluctant to show anything
of them where there is a remote possibility that they might be incorrect about something or something that'll have them not looked in a positive light? Seems like these people have their **** together, right? Well, no. Not necessarily, but they might be more insecure and have these types of issues. Pride being one of them. How they were brought up might also have something to do with it too.
I have a strange combination of a big fear of being "wrong" or having people know that I do (or have done) things that they might judge me less-than-positively on. But yet, I can't be bothered to act too much like the "always right" people like what I described earlier. I'll be alright with having something not be looked at as the "proper" way to act. The hell with that snobby nonsense.
Just some food for thought I'd throw out there, from my experiences and analysis.
Better yet are you one of those people and can give me some insight into why you refuse to admit your wrong.
I seriously doubt anyone here who falls into that category is going to even think about admitting this to you and answer this question. Ironically, answering is question would require them to have to forfeit some of their pride (among other things) and thus would sort of defeat the purpose of upholding why they think they are "always right" in the first place.
