I haven't seen any work specifically on the impact of consistency  
with security cues. The closest reference I can think of comes from a  
study that used an eye-tracking device (see Gathering Evidence in our  

Results are reported that correlate someone who claimed they checked  
for and saw a lock icon for a page to the event of them looking in  
the wrong corner for the lock icon. Their data also shows they  
reported using a different browser than the one in the study, the  
browser they use shows the lock in the left corner, while the browser  
in the study had another icon in the left corner.

While this is only one data point, there are also papers in HCI  
design principles that push for consistency whenever possible. IMO,  
if consistency helps reduce confusion for things like menu design and  
other GUIs,  it can't hurt us to strive for consistency in our
