It is strange how most people are oblivious as to how they meet a stereotype
I will start off with an easy example. "Karens". It has been many years that the term "Karen" has been a thing. Yet, even today, there are many Karens in the wild, and they are completely oblivious as to how they are perceived. Even before the term "Karen" was popularized, people already knew the concept/type of person, it was mostly referred to as the "I want to see the manager" type. So even before the term Karen, how were these people so oblivious as to not realize who/how they were?
There are tons of other stereotypical characters and most people fall under one of them. Yet again, they seem completely oblivious to it. I mean how can you go your entire life not realizing this? How can you not put 2 and 2 together? How can you not use your eyes and ears and not detect such basic patterns and ask yourself even once after years/decades "am I being like that?" or "how do others perceive me"?
I just find it bizarre: most people fall into a stereotypical way of being/thinking, and they remain completely oblivious to this. I don't get how you can go your entire life and the question "is what I am believing in/how I am acting right? Where did it come from? How does it come across to others? The stuff I find bad or annoying in others, is it possible that there is even one thing about me that evokes this same perception in others? Do I need to change?" Yet bizarrely for the vast majority, they are like NPCs and go their entire life never once having one of these questions even pop up in their mind, or if it does, they certainly let it fade away without give it another thought.
