I read about an instant cake mix that was a big flop. The instructions said all you had to do was add water and bake. The company couldn’t understand why it didn’t sell -- until their research discovered that the buying public felt uneasy about a mix that required only water. Apparently people thought it was too easy. So the company altered the formula and changed the directions to call for adding an egg to the mix in addition to the water. The idea worked and sales jumped dramatically.
