If I offer you a burger stuffed with 25 percent fat, there¡¯s a higher chance you¡¯ll opt for the chicken salad than if my menu promises a hamburger of 75 percent lean beef. Never mind that the burgers are indistinguishable; describing objects and situations in positive terms makes them more appealing than when negative words are used.
