It’s the lost-cause fallacy. They’re incapable of self reflection because it could compromise their entire identity/beliefs.
Talk to anyone who worked in hospitals during the height of COVID. All of them encountered people gasping for air as their lungs filled with covid pneumonia, on their death beds insisting they did not have covid, and it was all a government conspiracy. Even on their deathbeds, these people still cannot accept reality.
