I tend to be a bit skeptical when studies are based on extroversion and introversion, if only because I can test on all parts of the spectrum depending on my mood.
I think people shackle their identity to their *version, and it can be limiting.

In general I'm fairly skeptical of personality tests, beyond just intro/extro version, for the similar reason that a) I can test vastly different based on my mood and b) people tend to tie their self image to the results and you end up with a tail-wagging-dog situation.
I'm just glad so many managers are cool with responsible use of headphones & noise cancellation approaches these days. Certain tasks simply require more focus.
