Question of how delusional beliefs are caused

Is delusional beliefs caused by creating false memories or making up lies and believe at those false memories or lies pervasively and believing those beliefs so strongly and sometimes with lack of true insight?

Option 3: delusions are created by the introduction of a false statement which is incorrectly perceived as truthful, which then in turn influences the perception of anything that contradicts the new "truth".

A bit like how you could teach someone for their entire youth that 1+1 = 11, and then you provide proof of it being 2, so the brain has to adjust. Once it chooses to believe 1+1 = 2, it then discards any old memories saying otherwise.

Gaslighting works similar too. In general you can make someone believe a fallacy if you are persistent enough.

To look at your options, it's a bit of both but also neither of those options. You don't make these things up. You are somehow triggered to believe something.

That actually makes sense. I did wonder if development believing in false memories or lying to yourself too much can create unhealthy self-delusion, like in severe form of Narcissistic Personality Disorder.

Some people believe that people with Narcissistic Personality Disorder lie to to themselves too much that bags to question if they became delusional overtime, not that it's the same as as traditional psychosis. But only some people with Narcissistic Personality Disorder lie to themselves that are harmful to others, most of them cause relationship issues that severe harm.

Some people generalize people with Narcissistic Personality Disorder as being all the same, but because not every person with Narcissistic Personality Disorder are the same, generalizing people with Narcissistic Personality Disorder as being all bad is stigmatizing.

Some websites say that people with Narcissistic Personality Disorder lie to themselves too much and are delusional overtime, but I get confused, because they don't use the word 'some', because not everyone with Narcissistic Personality Disorder are going to have all the traits.

Please, educate me if I am wrong

I'm terribly sorry. Life was rather chaotic and busy for me for a while there.

So the thing with narcissism is that it usually is a behavioural front for an insecure person. They need the attention and suffer physically if they aren't the centre of attention.

So a delusion or psychosis requires you to believe what you're thinking /experiencing. At least initially, and then behave accordingly. In example, your delusion could make you believe that you are the envoy of God with magic abilities. You will believe this.

A narcissist doesn't believe things that are improbable or even impossible unless they experience delusions thanks to a different problem. Narcissists simply are convinced that they are deserving of better things than others.

It's a difference between arrogance and having lost touch with reality, to put it very broadly.
Does that explain it a bit ?

That clearly explains it better, but NPD can resemble a delusion when it's severe.
