so, i pose a new question .. as the barstool experiment tends to 'solve' the new age metaphysics nothing is real hippie stuff .. is there a similar way to cure common paranoia? 
Concerning the Barstool Experiment, I feel that the lesson to be taken from it isn't that it "solves" metaphysics, but rather that you need to be aware of both the Universe you create in your head, as well as the Universe you are receiving signals from.
Metaphysics can be fun, and they can lead to revelation and epiphany, but don't think that it will feed your family, unless you can get a book deal out of it.
As to your other question, "common" paranoia seems to be generated by insufficient observation combined with self-deception and pessimism.
If you try to Find Out as much as possible about Things, you'll soon find that the "common" paranoia soon vanishes...
...and is replaced by REAL paranoia.
Then again, you can always just realize that 95% of the human race is on self-destruct auto pilot, which tends to make the whole issue moot.
