QUOTE : Triggers explain why. Even a bad review or negative word of mouth can increase sales if it informs or reminds people that the product or idea exists. That’s why a sixty-dollar Tuscan red wine saw sales rise by 5 percent after a prominent wine website described it as “redolent of stinky socks.” It’s also one reason why the Shake Weight, a vibrating dumbbell that was widely ridiculed by the media and consumers, went on to do $50 million in sales. Even negative attention can be useful if it makes products and ideas top of mind.
