I admit to being wrong or being insensitive and believe strongly in apologizing or making amends. I do not know if the people you describe fear being wrong as much as they fear doing the work to make amends or apologize. I dont mean you have to debase yourself and grovel but there is power and freedom to being wrong and admitting it. Maybe people like that do feel its a flaw or have issues admitting them. I always felt that people that had a strong desire to be right even shutting out facts that "prove" they are wrong feared being vunerable. I do not know if its past trauma or abuse history or even bad role models. Maybe youre right and it is fear, I feel like I have talked in circles.
