You can't judge a book by its cover.
What sage advice. Except most people who are book shopping rely on the cover, and the blurb on the back cover or inside flap to determine whether or not he or she may purchase a book.
My take: Guess what? People do make snap decisions. Ever heard any cliches about making first impressions? We are in an internet age where people are judging you based on your Facebook and Instagram pictures, as well as you expressing yourself in 140 characters or less a few times a day.
It isn't "fair", and it isn't logical.
