This is something that we see in trials.  Even if we label the test groups
Red, Green, and Blue, it's sooo easy to find yourself rooting for one
color--even if you don't know what treatment that color represents.  It's
so hard for humans to remain impartial.  Blinding the graders/inspectors is
a pain, but necessary.
