Narcissistic defense sequences are like a set of behaviors that a person with a big ego might use to protect their feelings from getting hurt. When someone does or says something that makes them feel bad about themselves, they might act in certain ways to make themselves feel better.
For example, if someone tells a person with a big ego that their idea is not very good, they might use one of these sequences to defend themselves. They might first deny that the idea is bad and insist that it's actually great. This is called denial.
If the person still insists that the idea is not good, the egocentric person might get angry and yell at them. This is called anger. They might try to make the other person feel bad and guilty for criticizing them.
If that doesn't work, the egotistical person might then try to make themselves feel better by belittling or insulting the other person. This is called projection. The person might say something like, "Well, that's just because you're not smart enough to understand the brilliance of my idea, unlike me. I'm a genius!"
All of these behaviors are used to defend oneself against criticism or anything that challenges their view of themselves as superior. However, these defense mechanisms can be unhealthy and can prevent someone from being able to learn or grow from constructive criticism or feedback. That's why it's important to be aware of them and work on developing more constructive ways of coping with criticism.
