Of course it's possible to mature, but only if people want to. People who actively want to become less self-centered are not narcissists, by definition.

So it is possible to cure narcissism, if only the narcissist wants to be cured?

That is a very far cry from being described as 'incurable', which I have seen used a lot.

Again, I am not saying that narcissism doesn't exist, but the language that is being used to describe it is unhelpful.

A lot of people go through phases in their teens or 20s that could be described as narcissistic, and then they develop out of it.
