The clothes maketh not the peacock

Contrary to what I'd previously believed a study conduced in Japan revealed that peahens (like the dull-grey one on the left) aren't at all impressed by the size or brilliance of the peacock's plumage, nor by how neatly it's been pressed at the dry-cleaners.

According to the study it's what the peacock says that makes all the difference. I have reason to believe this may too apply to the human race.
