"Let us briefly summarize the evidence. In everyday life, bad events have stronger and more lasting consequences than comparable good events. Close relationships are more deeply and conclusively affected by destructive actions than by constructive ones, by negative communications than positive ones, and by conflict than harmony. Additionally, these effects extend to marital satisfaction and even to the relationship's survival (vs. breakup or divorce). Even outside of close relationships, unfriendly or conflictual interactions are seen as stronger and have bigger effects than friendly, harmonious ones. Bad moods and negative emotions have stronger effects than good ones on cognitive processing, and the bulk of affect regulation efforts is directed at escaping from bad moods (e.g., as opposed to entering or prolonging good moods). That suggests that people's desire to get out of a bad mood is stronger than their desire to get into a good one. The preponderance of words for bad emotions, contrasted with the greater frequency of good emotions, suggests that bad emotions have more power. Some patterns of learning suggest that bad things are more quickly and effectively learned than corresponding good things. The lack of a positive counterpart to the concept of trauma is itself a sign that single bad events often have effects that are much more lasting and important than any results of single good events. Bad parenting can be stronger than genetic influences; good parenting is not. Research on social support has repeatedly found that negative, conflictual behaviors in one's social network have stronger effects than positive, supportive behaviors. Bad things receive more attention and more thorough cognitive processing than good things. When people first learn about one another, bad information has a significantly stronger impact on the total impression than any comparable good information. The self appears to be more strongly motivated to avoid the bad than to embrace the good. Bad stereotypes and reputations are easier to acquire, and harder to shed, than good ones. Bad feedback has stronger effects than good feedback. Bad health has a greater impact on happiness than good health, and health itself is more affected by pessimism (the presence or absence of a negative outlook) than optimism (the presence or absence of a positive outlook). Convergence is also provided by Rozin and Royzman (in press). Quite independently of this project, these authors reviewed the literature on interactions between good and bad, and they too concluded that bad things generally prevail. Our review has emphasized independent, parallel effects of good and bad factors, whereas theirs emphasized good and bad factors competing directly against each other in the same situation (such as contagion). Both approaches have confirmed the greater power of bad factors. Thus, the greater impact of bad than good is extremely pervasive. It is found in both cognition and motivation; in both inner, intrapsychic processes and in interpersonal ones; in connection with decisions about the future and to a limited extent with memories of the past; and in animal learning, complex human information processing, and emotional responses."
