Passage (3)1It's plain common sense--the more happiness you feel, the less unhappiness youexperience. It's plain common sense, but it's not true. Recent research reveals thathappiness and unhappiness are not really flip sides of the same emotion. They are twodistinct feelings that coexist, rise and fall independently. 2"You'd think that the higher a person's level of unhappiness, the lower their levelof happiness and vice versa," says Edward Diener, a University of Illinois professorof psychology who has done much of the new work on positive and negative emotions.But when Diener and other researchers measure people's average levels of happinessand unhappiness, they often find little relationship between the two. 3The recognition that feelings of happiness and unhappiness can coexist much likelove and hate in a close relationship may offer valuable clues on how to lead a happierlife. It suggests, for example, that changing or avoiding things that make youmiserable may well make you less miserable but probably won't make you anyhappier. That advice is backed up by an extraordinary series of studies which indicatethat a genetic predisposition for unhappiness may run in certain families. On the otherhand, researchers have found, happiness doesn't appear to be anyone's heritage. Thecapacity for joy is a talent you develop largely for yourself.
