I would argue that kind of personality is due to the opposite of nature. It was a rewarded behavior that has been nurtured over time to become weaponized, from a certain perspective. Having insecurities is to be human, but anxiety and discomfort has to come from a willingness to endure them. The society around your close friend has rewarded this analytical behavior and so they leaned into it rather than becoming avoidant. My personal belief is that it comes from a place of accepting the behavior objectively and without judgement or negativity. If you spend so much time and energy on just analyzing yourself, you don't have as much room for others and this reflects as a sort of narcissism. But that doesn't actually reflect how much they care about others. Humans have to self regulate their bandwidth for how much external things will affect them. I don't know if it's behavior to be actively avoided, because from their perspective, it's something they feel the opposite of indifferent to. Making decisions from a place of having mapped out most, if not all, possibilities leads to more positive outcomes in the long term. I understand that not everyone will want to spend that kind of energy to guarantee that kind of security in their decisions. Not everyone feels they need that kind of security before making decisions.
