Emotions aren’t good or bad – they’re useful

You’ve probably heard the distinction countless times: positive emotions like joy, pride, gratitude and love are good for you, while negative emotions like anger, fear, disgust or sadness are bad news.

The message is usually clear, even when it’s implied rather than stated outright: cultivate the positive, suppress the negative, and you’ll live a healthier, happier life. It sounds sensible. After all, who wouldn’t prefer to feel happy rather than anxious, calm rather than angry, content rather than sad?

But this advice rests on a subtle misunderstanding – one that quietly turns our emotional lives into a moral battleground. And when left unchallenged, that misunderstanding can actually make us less well, not more.

The problem is not that some emotions feel pleasant and others unpleasant. The problem is that we’ve come to confuse pleasant with good, and unpleasant with bad. Once that confusion takes hold, we don’t just experience emotions; we start judging ourselves and others for having them.

To understand why this matters, we need to take a closer look at what psychologists really mean when they talk about positive and negative emotions.

Valence, not value

At the heart of this confusion lies a technical term that has escaped the psychology textbooks and wandered into everyday life: valence. When psychologists describe emotions as positive or negative, they’re not making a moral judgement. They’re describing valence – whether an experience feels pleasant or unpleasant. That’s all.

Valence refers to the felt quality of a situation: whether something feels attractive or aversive, comfortable or uncomfortable. It’s not about whether the emotion is justified, healthy, appropriate, or desirable. Anger, fear, sadness and disgust tend to have a negative valence because they feel uncomfortable. Joy, relief, affection and excitement tend to have a positive valence because they feel pleasant. But that doesn’t make one set good and the other bad.

Somewhere along the way, however, this neutral descriptive language became moralised. Positive quietly came to mean healthy, constructive or virtuous, while negative came to mean unhealthy, toxic or problematic. And once that shift happens, unpleasant emotions don’t just feel bad; they start to feel wrong. This is where trouble begins.

“But negative emotions feel bad!”

One common response is: surely fear or anger are negative because they feel awful? And it’s true, they often do. Fear tightens the chest. Anger heats the body. Disgust makes us recoil. Sadness can feel heavy and hollow. But those unpleasant sensations aren’t design flaws. They’re features.

Emotions with a negative valence are meant to interrupt us. They grab our attention because something important is at stake. Fear alerts us to danger, disgust warns us to keep our distance, anger signals threat, violation or injustice, while sadness marks loss and invites care, from ourselves and from others. If these emotions felt neutral or pleasant, we’d be far less likely to respond appropriately. The discomfort is what makes the signal hard to ignore.

The problem arises when we dismiss the signal simply because it feels bad or because we’ve absorbed the idea that 'negative' emotions are something to get rid of.

So what are emotions, anyway?

Despite decades of research, we’ve still not agreed on a single definition of what emotions actually are, but we can agree on a few things. Emotions are not just thoughts, and they’re not just bodily reactions. They’re patterns of experience that involve bodily sensations, interpretations, memories, social meanings and action tendencies all working together. They prepare us to respond to what’s happening.

Crucially, emotions are also shaped by culture. If I ask you what sadness feels like, you might describe a heaviness in your chest, tears welling up, a sense of withdrawal. Even though your sadness won’t feel exactly like mine, we recognise it in each other. It’s part of a shared emotional vocabulary. But what about liget, an emotion specific to the Ilongot people of the Philippines?

Liget speaks of anger, energy, passion and headstrong intensity. It translates to something like “high voltage emotion”, and there’s no direct English equivalent. Much closer to home, the Portuguese saudade describes an emotional state that’s in part a nostalgic longing for something lost interwoven with an ongoing awareness of the thing’s absence, and it's an emotional experience that's difficult to express outside Portuguese and Brazilian culture, as saudade has no direct English equivalent.

Liget and saudade remind us that emotions are not fixed objects inside us. They’re ways of relating to the world that are shaped, among other things, by history and culture.

Emotions are information

One of the simplest and most useful ways to think about emotions is this: emotions are data, information about what’s going on in our relationship with the world. They tell us what matters, what threatens us, what draws us in, and what pushes us away. If you open the fridge and smell something rancid, disgust kicks in to stop you eating food that could make you ill. Interpersonal disgust works in a similar way, but this time it’s people’s behaviour that feels toxic, unsafe or corrosive.

Anger, despite its unhelpful reputation, is an equally important signal. It tells us that a boundary has been crossed, a threat detected, or an injustice experienced. There’s a long history of women being shamed for their anger, while male anger is often wrongfully conflated with violence and aggression. As strange as it might sound, pathologising anger can undermine our well-being when anger is a healthy response to being mistreated, ignored or harmed.

More than a feeling: emotions guide action and connection

Emotions don’t just inform us; they move us. They help us make decisions by highlighting what matters. Neuroscientist Antonio Damasio famously showed that some people with brain injuries that flatten emotional experience can struggle to make simple decisions. Without emotional signals, everything feels equally unimportant.

Emotions also help us understand one another. When you see someone’s sadness, you might soften, slow down, offer comfort. When you see joy, you might smile and share it. Our emotional expressions coordinate social life. This capacity to resonate with others’ emotions is a cornerstone of human connection. To ignore emotional cues – our own or others’ – is to ignore a vital layer of social meaning.

When emotions become moral problems

If emotions simply provide useful signals, what’s gone wrong? The short answer is that we’ve taken a cultural wrong turn and turned valence – the felt pleasantness or unpleasantness of an emotion – into a value judgment, with unpleasant emotions treated as moral or psychological failures rather than meaningful responses.

In contemporary well-being culture, there can be an unspoken rule: you should feel good and, if you don’t, something is wrong with you. Anxiety becomes weakness, sadness becomes pathology, anger becomes toxic.

This doesn’t just hurt; it creates a second layer of suffering. Psychologists call this meta-emotion: how we feel about how we feel. Feeling anxious is hard enough; feeling ashamed for being anxious is worse. Feeling angry is difficult; feeling guilty for being angry compounds the pain. Ironically, it’s often this moralised response to emotion, not the emotion itself, that keeps distress stuck.

Ignore your emotions at your peril

If emotions are information, what happens when we ignore the data? If you ignore disgust, you might eat spoiled food or stay in a relationship with someone whose behaviour makes you feel unsafe or diminished. If you ignore fear, you may keep exposing yourself to danger. If you ignore anger, injustice and boundary violations continue unchecked.

And emotions don’t disappear just because we refuse to listen. They tend to find other ways to make themselves known: through tension, rumination, exhaustion, resentment or numbness. Suppressing emotions doesn’t solve the problem; it often just buries the message.

Emotions as ways of engaging with the world

Recent developments in psychology and philosophy offer a new way to think about emotion. From this perspective, emotions are not things that happen inside us; they are ways of engaging with the world that arise from the ongoing relationship between us and the situations we find ourselves in.  Fear isn’t just a feeling – it’s a way the world shows up as dangerous. Anger is a way the world appears as unjust or threatening. Sadness is how loss makes itself known. Joy is how connection and possibility are revealed.

Valence, in this view, isn’t a value label stamped on an emotion. It’s the felt sense of whether our engagement with the world is flowing smoothly or meeting resistance. Seen this way, negative valence doesn’t mean something has gone wrong inside you. It means something matters, and it’s not going well.

When emotions persist

People sometimes say that 'negative' emotions hang around too long. Sometimes that’s true, but often emotions persist not because there’s something wrong with the person, but because the situation hasn’t changed.

If you’re sad due to an ongoing loss, angry in a persistently unjust environment, or anxious in a chronically uncertain situation, your emotions may be doing exactly what they’re meant to do: refusing to let the issue slip from view.

Instead of asking "How do I get rid of this feeling?", a more useful question might be: "What is this emotion telling me about the situation I’m in?"

Be my light, be my guide

If we strip away moral judgement, emotions start to look less like enemies and more like guides. Fear can point us toward protection, anger can help us identify and defend boundaries, sadness can invite rest, reflection and connection. Even anxiety can sharpen our attention when uncertainty matters.

This doesn’t mean every emotional impulse should be acted on without reflection. Emotions are signals, not commands, but ignoring them entirely is rarely wise. The ancient Greek playwright Sophocles warned against shooting the messenger, and when it comes to emotions, the message really matters.

Toward a healthier emotional culture

A healthier emotional life doesn’t come from relentless positivity. It comes from emotional literacy: the ability to recognise, tolerate, interpret and respond to the full range of human feeling. That means replacing moral labels with curiosity.

Instead of asking whether an emotion is good or bad, we can ask, what is this emotion responding to? What does it reveal about what matters here? What action, if any, does it invite? When we do this, emotions stop being problems to eliminate and start becoming sources of guidance. They were never the enemy; we’ve just misunderstood their role.
