Anger Isn’t the Opposite of Depression 

Here’s What Actually Separates Them 

Anger and depression are often conceptualized as opposite states by evidence-based cognitive behavioral therapists (CBT). And in some ways they are very different, but they do have similarities, as well. 

If we want to reduce our anger and depressive symptoms, it’s crucial for us to understand both.¹

The Science Behind Anger vs. Depression

Emotions can be viewed on two axes: arousal and valence. Arousal can be either high or low. Excitement, joy, terror, and rage are all characterized by high arousal, meaning they have a lot of energy. Annoyance, distraction, apprehension, and boredom have low arousal. Valence can be positive or negative. So, joy and excitement have positive valence, and guilt, anger, and sadness have negative valence (Plutchik, 1991). You can plot emotions on X and Y axes. This helps us visualize the similarities and differences from an experiential or phenomenological perspective. You can imagine that most of us would love to spend our lives in the top right quadrant. Bring on the positive highs! That’s what many drugs are designed for, prescription and recreational.

Anger and depression are both negatively valenced, but their arousal distinguishes them. That difference in energy level is obvious to anyone who has ever been depressed or enraged. When we’re depressed, curling up in a fetal position, under a blanket, in the dark doesn’t feel good, but feels less bad than everything else. Now, when you’re enraged, or you imagine someone really pissed, try telling yourself or them to sit down and be quiet. Good luck with that.

Emotions come with energy, valence (affect), and behavioral scripts, or tendencies to want to do certain things (which could be verbal behavior, i.e., behaviorist language for talking). Profanity and yelling are behavioral tendencies with scripts that go along with rage. Calmly, warmly, assertively communicating to a perpetrator thoughts, feelings, and a request is not the most natural script for most of us when we are really angry. Likewise, when we are depressed, jumping out of bed, throwing up the shades, blasting “It’s the end of the world as we know it” by REM, and rushing out the door to take on the world isn’t usually Plan A for most of us. Recognizing the arousal, valence, behavioral tendencies, and thoughts that go with emotional states can help us change their frequency, intensity, duration, and latency, what I call FIDL.

Cognitive Differences Associated with Emotions

So let’s talk about one of the most surprising differences between anger and depression (or rage and sadness). According to cognitive theorists like Albert Ellis and Aaron Beck, our thoughts about ourselves, other people, what they or we have done, situations, life, the past, and the future determine how we feel. In other words, cognitive interpretations of things equal emotions (Ellis, 1962; Beck, 1967). For now, if we accept that, what are the cognitions associated with depression and rage that are different? Both are negative emotions. But counterintuitively, there is a positive thought, if you want to call it that, associated with rage that isn’t present for depression: hope. Hope can be categorized as a cognition or an emotion. Regardless, hope, or at least one cognitive component of hope, is what is absent from the thinking that goes with a depressive state. Hope indicates a belief that things can change; the future could be different.

When we are enraged, themes of injustice, hostile attribution, and blame permeate our thinking. And with all that negativity, there is also at least a sliver of the belief that the situation or person can be changed. So, yelling, hitting, drafting letters, and more all make sense. If I do something, something could change; my present and future, and that of others, could be different.

But when we are depressed, hopelessness is part of the package. The present is uncomfortable or unbearable, and the future looks bleak, with no end or improvement in sight. Depression is a state of not having hope that anything I can do will make things better. It is the epitome of what psychologists call low self-efficacy. Self-efficacy is the belief (a thought/cognition) that I can do something and that act will change things. An animal study by Seligman and Maier (1967) shows what this looks like from a behavioral perspective. First, honestly, I hope this kind of study wouldn’t make it past an ethics review board today. Dogs were put in different conditions where their behavior either did or did not stop them from receiving an electric shock. Then, when they were all put in a box where there was a shock from the floor, but they could all move forward to escape the shock, the ones who had control over stopping the shock before did just that: they jumped over a barrier and escaped the shock, landing in a safe place. Those who couldn’t turn off the shock in the earlier condition, even when put in this box where they could jump over a barrier to a safe place, instead just lay down on the floor that was shocking them, whimpering, and “taking” the pain. Now we may not want to anthropomorphize them or believe these dogs think as we do. But their behavior looks just like ours when we are depressed. We both behave as if there is no hope; no matter what I do, it is of no use; nothing will change; just lie down and suffer.

Interestingly, there may have been an evolutionary role for these depressive symptoms. Consider a thought experiment: imagine a baby bird in a nest after its mother leaves to forage. The bird could remain active, chirping and moving about, burning calories with each movement. Or it could become quiet, still, and subdued, conserving those precious calories. If the mother is gone for days, which strategy helps the bird survive? The quiet bird needs fewer calories and can wait longer for the return. The active bird burns through limited reserves rapidly. Now, if the mother is gone for many days, whose happy now? Nobody. The sad baby bird is still sad, but alive. The happy bird is dead.

This energy conservation hypothesis suggests our ancestors who possessed the capacity to become withdrawn, inactive, and unmotivated during periods of hardship may have survived longer than those who remained perpetually active and driven. Evolutionary theories of major depressive disorder propose that sadness and low mood evolved as beneficial responses to adversity, with clinical depression representing a dysfunctional extreme of this adaptive response (Hagen, 2011; Wolpert, 2008). The behavioral shutdown associated with depression includes psychomotor retardation, disrupted sleep and appetite, loss of sex drive and motivation, and reduced activity levels; these are theoretically analogous to the body’s energy-conserving responses during physical threat or resource scarcity.

However, this remains a compelling hypothesis rather than established fact. The specific mechanisms of how emotional depression interfaces with metabolic rate in natural populations, particularly in developing organisms facing parental absence, await empirical investigation. Nonetheless, the theory elegantly explains why our capacity for depression persists in the human genome: it may have kept our ancestors alive during their darkest hours.

Now that we understand the thoughts, physiological states, and behavioral tendencies that accompany anger and depression, what can be done?

Evidence-Based Anger Management and Depression Treatment

I was tasked with writing an Evidence-Based Anger Management Treatment Protocol for the first experimental trial in an outpatient treatment facility for general patients, i.e., not a university counseling center or correctional facility. I was able to capitalize on the work of psychologists like Jerry Deffenbacher, who had demonstrated that relaxation, problem-solving, and communication skills, as well as cognitive coping, could reduce anger symptoms (Deffenbacher & McKay, 2000). So I integrated those as well as motivational interviewing or enhancement, specific Rational Emotive Behavior Therapy (REBT) techniques, and a few other interventions into the anger management treatment. Our research team evaluated this comprehensive cognitive behavioral anger treatment approach with adults seeking treatment in an outpatient setting (Fuller et al., 2010). After 16 weeks of treatment, we found that while they still faced roughly the same number of anger-triggering events in their lives, participants in this group therapy for anger management had fewer, shorter, and less intense anger episodes. That was good news. What was surprising is that many of them had depressive symptoms to start, and those too were not just statistically significantly lower, but clinical significance had also been reached. That means it wasn’t just likely that the intervention resulted in a lower number on some score, but the difference made a meaningful clinical change in their experience and functioning. So, here was evidence that a treatment that reduces anger also reduces depression. Now it could be that the interventions addressed mechanisms that drove both the anger and depression, and/or that by reducing the anger, participants became less depressed, or vice versa. Nonetheless, if we are angry or depressed at levels we want to change, something can be done. There is scientific evidence for hope.

Footnotes 

1. For the sake of this article, I’m going to speak about depression as an emotion, like sadness, while recognizing Major Depressive Disorder (MDD) is a clinical diagnosis that consists of symptoms of sadness, hopelessness, guilt, and vegetative symptoms like changes in appetite, sleep, weight, and sex drive.

Frequently Asked Questions: 

1. What is the difference between anger and depression?
Although both are negatively valenced emotions, they differ in arousal. Anger is typically a high-arousal state associated with increased energy and an urge to act, while depression is often characterized by lower arousal, reduced energy, withdrawal, and decreased motivation.

2. What does hope have to do with anger and depression?
Anger can contain an implicit belief that something could change. If we believe an injustice can be corrected, anger may motivate us to take action. Depression, in contrast, is often accompanied by hopelessness, or the belief that our actions will not make a meaningful difference.

3. Can anger and depression occur at the same time?
Yes. Anger and depression are not mutually exclusive. Someone can experience significant anger or irritability while also experiencing sadness, hopelessness, low motivation, or other depressive symptoms. In some cases, these emotional states may reinforce one another.

4. Can we change how we experience anger or depression?
Yes. Although we cannot always control when an emotion appears, we can influence its intensity, duration, and how we respond to it. Learning to recognize the thoughts, physical sensations, and behavioral urges associated with an emotional state can create opportunities to respond differently.
