My interpretation of paranoia is that it's something that we've learned through a reaction-stimulus conditioning.. Sort of like the Pavlovian theory. Ex- we watch something on the news repeatedly, the response is- we fear that person, object or event that was previously a neutral response.
Here's a really interesting piece:

Personally for me, intuition comes from a place of calm. It usually tells me something about the person, place or thing- not necessarily a positive or negative response, but something idiosyncratic.
I think accusatory assumptions come from prejudice, which stems from a learned response.
Intuition for me is also say.. when someone covers up an emotion and says, "I'm okay" when they're really not..
That's how I see it.. and agree with what the video says for the most part.
