Yes, I think of it like a child in a family who doesn't have much contact with other families. So, until the child is older and does more on his own, what he experiences is his "norm" whether it's a norm-norm or not. It's hard if you're raised to eat only McDonald's to then learn that you should be eating fruits and vegetables and can take quite awhile, if it's possible, to switch over to eating more healthfully.

I am a woman and have read about and experienced walking down a city street. Women walking down a city street, are generally more hyper-aware of who is around them and what those people are doing, what sex they are, etc., especially if it is around nighttime. A man doesn't have as many worries about strength, size, sex, nighttime, etc. so doesn't have the same almost unconscious thoughts and anxiety in their body. I think that's sort of what it might be like to grow up psychotic, one gets "use" to it and just responds "as if" it were normal. There's nothing wrong with thinking people are following you and out to get you but it makes life more difficult since we need to get along with other people and life is more pleasant with their help and companionship.
