As an addendum...

My question is speculative as are any answers produced because this thread is not likely to draw the hundreds of responses that might be necessary to produce a verifiable pattern of consistency. It's not even producing consistency thus far! Of the three responses to date, all respondants report with the personality characteristic of introversion but the applied diagnosis are not consistent.

Assuming even that this thread did attract hundreds of responses, would that paint a true portrait of schizophrenia or bipolar disorder? We can't really know because you will probably find more introverts on the net than extroverts -- surfing the net tends to be a "solitary" activity. Therefore the only viable conclusion we might be able to draw would be that more introverts responded to this thread than extroverts. The extroverts are all at parties, that's why.</blockquote>
