Study Finds Anger is Healthier Than Fear

By:

He that is slow to anger is better than the mighty...
Proverbs 16:32

Well, maybe being slow-to-anger isn’t all that King Solomon made it out to be.

A provocative new study by Jennifer Lerner in the Department of Social and Decision Sciences (SDS) suggests that anger may be a healthier response than fear in situations in which anger is justified. Lerner’s study, published this past November in the journal Biological Psychiatry, found that people who respond to stressful situations with angry facial expressions, rather than fearful expressions, are less likely to suffer such ill effects of stress as high blood pressure and high stress hormone secretion.


Darwin first proposed that facial expressions of emotion signal biological responses to challenges and opportunities. More than a century later, a number of scientists have taken up Darwin’s hypothesis. One important, but unexamined, question concerned the biological significance of facial responses to stressful circumstances. Because stress responses are central to survival, stressful situations should be likely to reveal coordinated biological reactions and facial communication, in part to warn or warn off others.

“Analyses of facial expressions revealed that the more fear individuals displayed in response to the stressors, the higher their biological responses to stress. By contrast, the more anger and indignation individuals displayed in response to the same stressors, the lower their responses,” said Lerner, the Estella Loomis McCandless Associate Professor of Psychology and Decision Science at Carnegie Mellon.

The paper was co-authored by Roxana M. Gonzalez, an SDS doctoral student; Shelley E. Taylor, a professor of psychology at UCLA; and Ronald E. Dahl and Ahmad R. Hariri, affective neuroscientists at the University of Pittsburgh School of Medicine.

Their paper challenges two long-held assumptions: one, that stress elicits undifferentiated negative emotions and as a consequence produces a uniform biological response; and two, that all negative emotions, such as fear and anger, provoke the same psychological and biological reactions. This paper builds on a line of work led by Lerner showing that anger triggers feelings of certainty and control as well as optimistic perceptions of risk.

A landmark study by Lerner found that Americans’ initial emotional reaction to the Sept. 11, 2001, terrorist attacks predicted their risk perceptions two months later: those who reacted with anger were the most optimistic and the most likely to favor aggressive responses to terrorism. No other study, however, has demonstrated that a person’s facial expressions reveal changes in the body’s stress response systems.

“Anger can sometimes be adaptive. We’re showing for the first time that when you are in a situation that is maddening and in which anger or indignation are justifiable responses, anger is not bad for you,” Lerner said.

In the past, researchers have assumed that anger can contribute to coronary disease and hypertension. Although a chronically angry, explosive temperament may do just that, justifiable anger in response to short-term frustration appears to be a healthier response than fear.

During the experiment, 92 participants performed mathematical exercises, including counting backwards by seven from 9,095, and counting backwards by 13 from 6,233. To make the exercises more stressful, participants were informed of each mistake they made, and they were urged to go faster by a harassing experimenter. Participants, who also were asked to complete arithmetic problems from an intelligence test, were told these tasks were indicative of general intelligence and that their responses would be compared to other participants’ scores.

To ensure that the tasks were creating stress, researchers assessed the participants’ emotional states and measured their stress hormone (i.e., cortisol) level, pulse, heart rate and blood pressure during periods of relaxation as well as immediately following the exercises. Increases in those biological measures were less pronounced in the participants displaying anger and indignation than in the participants displaying fear.

Taken together, the data reveal that the face represents an important window into the influences of stress and emotion on health. Because facial expressions can be assessed from the first moments to the last moments of life, across cultures, across social contexts and even across species, these results open up new opportunities for tracking developmental trajectories in stress responses, for assessing culture-specific appraisal patterns, and for assessing stress responses in naturalistic work and family settings.

It is widely said that anger often results from fear. If that is so, then anger may represent, biologically, moving into a more active mode in response to threat, so that the individual feels more of a sense of control over it. In addition, it seems that most cultures stigmatize fear and regard at least some forms of anger as positive (“righteous anger”, the anger of a soldier when a comrade is killed). This socially-learned attitude might also make people have a better feeling about being angry than being afraid. However, the original findings about anger being bad for one’s health were, I believe, in relation to chronic anger. Clearly, whether anger is biologically less damaging to an organism than fear, a chronic state of arousal can’t be good. I come to this as the spouse of a Vietnam veteran with severe PTSD, and I see him react to (perceived) threats with anger.
