'[June 1982, Apple] The user tests were conducted in a specially
constructed room featuring a one-way mirror so observers could watch
the tests without being intrusive. ...
'When the software required confirmation from the user, it displayed
a small dialog box that contained a question, followed by two
buttons for positive or negative confirmation. The buttons were
labeled Do It and Cancel. The designers observed that a few
users seemed to stumble at the point the dialog was displayed and
clicked Cancel when they should have clicked Do It, but it
wasn't clear what they were having trouble with.
'Finally, the team noticed one user was particularly flummoxed by the
dialog box and seemed to be getting a bit angry. The moderator
interrupted the test and asked him what the problem was. He replied,
"I'm not a dolt. Why is the software calling me a dolt?"'
