I've read some anecdotal evidence supporting this as well (atleast for goods). A store owner can't sell a line of jewelery, so they write a note to an employee to cut the price in half. The employee misreads the note and doubles the price of the jewelery instead. All of a sudden the line sells out. Part of the reason is that if people notice something's cheap, they'll think the quality is cheap as well. And vice versa.
