How are narcissists able to think so fast in order to keep their secrets hidden?
Because they’ve done this their whole life. For us normal developed people we have a fight or flight instinct naturally embedded in us, which kicks in when we are threatened with survival. A narcissist’s survival is not getting found out. So, their fight or flight instinct is to deny and blame anyone who tries to hold them accountable. If you don’t fall for the blame game where they tell you it’s your fault, they will inevitably make everyone around them THINK it was your fault. There is no quick thinking. This is how they survive! Plain and simple.
