I agree with Blue Inanna on this subject.

I know very little about schizophrenia, except that one is subject to delusions and
it can be very serious trying to maintain the chemical balance. I know of several
people who were schizophrenic, and in each case the person was very intelligent.

Bipolar people don't have an intellectual disorder--it's a mood disorder--so in all
honesty, for me, an article like that doesn't offer too much authority. Frankly,
I've also seen people whom you could not read their facial expressions unless
you had a camera inside their brains. "Poker face", it's called. The psychopath is
exceptionally good at concealing feelings. We bipolar folks aren't as a general
rule, in my view.

To tell you the truth, I've seen little puppies that had a quick que on what the
facial expression was saying. I've lived long enough to know a look can mean anything in this world---we never know.
