Hi Justin,
Studies on this topic seem pretty scarce. The only one I'm aware of
is http://psychology.wichita.edu/surl/usabilitynews/51/menu.htm
Unfortunately for you it doesn't show a statistically relevant
difference in users perceptions of either, "Perceived
Disorientation", "Perceived Ease of Navigation", or Perceived
Frustration". What it does show is a speed difference in task
completion with a categorical index menu being slightly faster than a
drop down. BTW I don't think this was a very good user sample with
only 18 people and over 70 percent using the web more than 25 hours a
week.
Here's another interesting piece of info although not a "controlled"
study that you could use for "Proof":
http://urlgreyhot.com/drupal/node/view/1440
It shows a significant user preference for use of inline links as
opposed to an expanding menu nav.
