Another behavior related to Dunning-Kruger would be a tendency to appeal to some kind of superior credential, even and especially if it is completely unrelated to the given debate at hand. Such a credential would be physical age: “Well young man, I am twenty years your senior, I think I know a thing or two.” Or, “You’re talking to a decorated veteran, show some respect!” Or, “I’ve lived a good life, had a lucrative career, raised three upstanding children, and am a grandparent to boot! I think my opinion should matter!” This tendency to take shelter in some kind of superior, if wholly unrelated and even irrelevant credential, is widespread and sometimes very problematic. What is Creator’s perspective?

Here you are giving additional examples of platitudes that purport to defend the self through an appeal to rank and privilege in being older, wiser, more capable, more experienced, more productive, and so on, when those attributes and qualifications may not be at all germane to the current dialogue in being challenged in some way. So these are more automatic responses that may well be launched out of habit, as a quick solution for self-defense, to parry the blow with a retort as much as shed light on something or engage enough to consider someone's argument and give a thoughtful response about its merits. That would be using those presumed credentials potentially in some way that is actually useful and creates a real-life demonstration that they count for something and lead to greater strength, wisdom, discernment, and judgment as evidenced by the reasoned argument one might make under such a mantle of authority. But to simply puff out a chest of medals when one is confronted in some way about something having nothing to do with participating or leading others in combat is truly beside the point, even though it may hold a grain of truth, that someone tested by fire might deserve being treated with respect to give them their due about what they have been through and been able to accomplish under difficult circumstances, and so on. But again, showing off one's pedigree is not an answer for disagreements, differences of opinion, and perspectives. Most things of significance are deserving of at least some consideration and a credible answer to provide a reckoning for the disconnection or differing opinions on how to handle a disagreement. It is also clear to most pondering your question that these examples very much do reflect ego strength in action. A pre‑pared, pre-planned, pre-rehearsed, and habituated talking point meant to override criticism, by virtue of prior achievements, may or may not, and most likely will not, be even relevant to a current disagreement of some sort and, as such, will be found to be annoying, unsatisfactory, and likely to discredit the one who falls back on a quick rejoinder of this kind to deflect criticism.
