Empathizing is the capacity to share and understand another person’s emotional or mental state, and it is not a single skill but at least two distinct processes running on different brain hardware. One component, often called affective or emotional empathy, involves actually feeling a version of what someone else feels. The other, cognitive empathy, is about figuring out what someone is thinking or experiencing without necessarily catching their emotion. These two forms can operate independently, strengthen or weaken across a lifetime, and even be trained separately, which makes the science of empathizing considerably richer than the popular image of “putting yourself in someone else’s shoes.”
Two Systems, Not One
Brain imaging research has consistently shown that emotional and cognitive empathy recruit different neural circuits. When people experience emotional empathy, activity increases in limbic areas involved in processing feelings, including the thalamus, as well as regions tied to perceiving faces and bodies, and the so-called mirror neuron system in the premotor cortex. Emotional empathy produces stronger mirroring of observed bodily and mental states than cognitive empathy does, essentially creating a faint sensory echo of what the other person is going through.1PubMed. Is emotional contagion special? An fMRI study on neural systems for affective and cognitive empathy Meanwhile, empathizing with someone’s pain specifically activates the anterior insula and the anterior cingulate cortex, areas linked to the unpleasant feeling of witnessing suffering.2PubMed Central. The anatomy of empathy: Vicarious experience and disorders of social cognition
Cognitive empathy, by contrast, leans on prefrontal and temporal regions that handle perspective-taking and mental reasoning. In older adults, researchers have found that higher affective empathy is associated with patterns of deactivation in the amygdala and insula during demanding mental tasks, while higher cognitive empathy shows up as greater insula engagement during tasks requiring inhibition and control.3PubMed Central. Distinct neural correlates of emotional and cognitive empathy in older adults The takeaway is practical: someone can be excellent at reading what you think and poor at feeling what you feel, or vice versa. The two capacities are separable in the brain, in behavior, and in real life.
Empathizing Versus Compassion
People often use “empathy” and “compassion” interchangeably, but neuroscience draws a sharp line between them. Empathy for someone’s pain fires up that anterior insula and mid-cingulate cortex network, and the emotional tone is negative: you feel distressed along with the other person. Compassion, on the other hand, lights up medial orbitofrontal cortex and ventral striatum, areas associated with reward and positive affect. The feeling that accompanies compassion is warmth and concern, not shared pain.4Academic Press. Decision Neuroscience
This distinction matters because empathy without compassion can lead to burnout. Researchers tested this directly by putting volunteers through empathy training (practice feeling what others feel) and then through compassion training (practice feeling warmth and care toward others). Empathy training ramped up insula and mid-cingulate activity, while compassion training increased activation in the orbitofrontal cortex, ventral striatum, and pregenual anterior cingulate. The patterns of brain change were non-overlapping.5Social Cognitive and Affective Neuroscience. Differential pattern of functional brain plasticity after compassion and empathy training People who were first trained in empathy reported increased negative feelings when viewing others’ suffering, but after they received compassion training, positive emotions rose and the distress receded. The implication: raw empathizing can be emotionally costly, but layering compassion on top can serve as a buffer.
Where Empathizing Comes From
Empathizing is not uniquely human. Emotional contagion, the most basic form, appears across many social species. When one animal detects distress in another, its own emotional state shifts to match. This has been documented in primates, dogs, birds, and even rodents, though proving it rigorously is harder than it sounds.6PubMed Central. Emotional contagion in nonhuman animals: A review In rodents, emotional contagion for distress operates through neural structures that are homologous to those involved in human empathy, and it appears to have been selected by evolution primarily as a danger-detection system: using others as sentinels to warn of threats. Under certain conditions, this shared distress can also promote helping behavior, though rodents do so less reliably and more selectively than humans.7PubMed. Emotional contagion and prosocial behavior in rodents
In humans, these basic alarm-sharing circuits became elaborated into something far more flexible. We can empathize with strangers describing events we have never experienced, imagine the inner lives of fictional characters, and feel moved by art. That layering of emotional contagion, cognitive perspective-taking, and compassionate concern is what makes human empathizing distinctive, even though its evolutionary roots are ancient and shared.
How Empathizing Develops
Traditional developmental psychology placed the emergence of empathy somewhere in toddlerhood, but more recent work suggests markers of empathic concern and an early understanding of others’ distress show up in the first year of life.8PubMed. Empathy Development: Typical and Atypical Tracks, From Infancy to Early Childhood Newborns cry in response to other infants’ crying, a reflexive emotional contagion that is not yet true empathy but provides the scaffold. By around twelve months, infants begin showing comforting behavior toward distressed adults and other children. Over the next several years, cognitive empathy develops gradually as children learn to take another person’s perspective, a skill that continues to mature through adolescence.
These developmental windows are sensitive to the environment. Caregiver-infant interactions, school-based social-emotional learning programs, and broader cultural context all shape how empathizing unfolds.9PubMed Central. Rethinking empathy development in childhood and adolescence: a call for global, culturally adaptive strategies A child who grows up in a household with attuned, responsive caregiving has more opportunities to practice and receive empathic responses, which feeds back into their own developing capacity. That said, biology also plays a role: genetic variation in the oxytocin receptor influences baseline empathic tendencies from an early age.
The Genetics and Chemistry of Empathizing
Oxytocin, sometimes oversimplified as the “bonding hormone,” genuinely plays a role in empathizing, though not quite as straightforwardly as popular accounts suggest. People homozygous for the G allele of a particular oxytocin receptor gene variant (rs53576) score higher on behavioral measures of empathy than those carrying one or two copies of the A allele.10PubMed Central. Oxytocin receptor genetic variation relates to empathy and stress reactivity in humans Other variants of the same receptor gene have also been linked to trait empathy, with some findings suggesting that genetic differences contribute to the commonly observed gap between women’s and men’s self-reported empathy levels.11PubMed. The association between oxytocin receptor gene polymorphism (OXTR) and trait empathy
Administering oxytocin as a nasal spray has been shown to increase empathic and self-embarrassment ratings while simultaneously reducing activation in the amygdala and insula, suggesting it dampens the raw emotional arousal while still boosting the empathic response itself.12PubMed Central. Oxytocin Facilitates Empathic- and Self-embarrassment Ratings by Attenuating Amygdala and Anterior Insula Responses But the effects are not uniform. One study found that oxytocin selectively improved empathic accuracy in men who scored higher on autistic-like traits, while having no measurable effect on women regardless of their trait profile.13Biological Psychiatry: Cognitive Neuroscience and Neuroimaging. Oxytocin Selectively Improves Empathic Accuracy in Men and Does Not Influence Empathic Accuracy in Women These findings suggest oxytocin is not a universal empathy booster but a modulator whose effects depend on who is receiving it and what empathic profile they already have.
When Empathizing Breaks Down Differently
Psychopathy and autism are both described as involving empathy deficits, but the nature of the deficit is almost opposite. In boys with psychopathic tendencies, the pattern is dysfunctional affective empathy: they understand what others think and feel but report less fear and less empathy for victims of aggression. Their cognitive perspective-taking, however, is intact. Boys on the autism spectrum show the reverse profile, with difficulties on tasks requiring cognitive perspective-taking but emotional responses and victim empathy in line with comparison groups.14PubMed Central. Feeling, caring, knowing: different types of empathy deficit in boys with psychopathic tendencies and autism spectrum disorder
This dissociation has led researchers to conclude that while both conditions involve social cognition difficulties, the specific empathic mechanisms that break down are different.15PubMed. Fine cuts of empathy and the amygdala: dissociable deficits in psychopathy and autism The picture gets more nuanced still when alexithymia enters the frame. Alexithymia, which is difficulty identifying and describing one’s own emotions, often co-occurs with autism but is a separate trait. Research in preadolescents found that alexithymia predicted empathy difficulties significantly better than autistic traits themselves did.16PubMed Central. Alexithymia and Autistic Traits as Contributing Factors to Empathy Difficulties in Preadolescent Children And in autistic youth with co-occurring alexithymia, the finding is that they may experience emotional empathy differently, but it should not be characterized as an absence of the capacity for emotional empathy altogether.17PubMed Central. Relationships between alexithymia, interoception, and emotional empathy in autism spectrum disorder
For psychopathy, the story is different again. Recent work using fine-grained measures found that primary psychopathic traits were associated with reduced affective empathy and inhibition of positive emotion imitation, even when these individuals reported normal levels of self-other overlap during behavioral synchrony tasks. Their cognitive empathy difficulties, meanwhile, appeared to be mediated through alexithymia rather than through the psychopathic traits themselves.18Personality and Individual Differences. A “fine-cuts” approach disentangling psychopathic, autistic and alexithymic traits in their associations with affective, cognitive and motor empathy Alexithymia seems to sit at a crossroads, contributing to empathy difficulties across multiple conditions.19Personality and Individual Differences. Investigating the role of alexithymia on the empathic deficits found in schizotypy and autism spectrum traits
In-Group Bias and the Limits of Automatic Empathizing
Empathizing is not applied equally to everyone. Brain imaging studies have revealed consistent evidence that people show stronger neural responses to the perceived pain of same-race individuals compared with people of a different race, across multiple brain regions and time windows.20PubMed. Neurocognitive Basis of Racial Ingroup Bias in Empathy This bias extends to other group boundaries as well. In one study, the empathic brain response was larger when participants watched a painful event happening to a hand labeled with their own religion than to one labeled with a different religion.21PubMed Central. Empathic Neural Responses Predict Group Allegiance Each of the three main components of empathizing, from emotional resonance to cognitive perspective-taking to compassionate concern, can be individually influenced by group membership.22PubMed Central. The influence of group membership on the neural correlates involved in empathy
None of this means empathizing across group lines is impossible. It means that the automatic, reflexive layer of empathizing is tuned toward people we perceive as “like us,” and extending it further requires cognitive effort. This has real-world implications for healthcare, policing, education, and any setting where someone in a position of power needs to accurately perceive and respond to another person’s distress.
The Cost of Empathizing Too Much
Empathizing is generally treated as a virtue, but absorbing others’ distress without relief carries a real cost. Compassion fatigue, a state of deep psychological, physical, and social exhaustion, occurs when a caregiving relationship founded on empathy leads to prolonged exposure to another person’s suffering.23PubMed. Compassion fatigue in family caregivers: a Wilsonian concept analysis It has been well documented in professionals like nurses in palliative care, where the central themes include emotional pressure, reflection of the patient’s pain, an imbalance in empathy, worsening physical and psychological complaints, and reduced vitality.24PubMed Central. Compassion fatigue in palliative care nurses: from empathy to emotional detachment But it is not limited to professionals. Family caregivers of people with dementia are also at risk.25PubMed Central. Compassion fatigue: an application of the concept to informal caregivers of family members with dementia
People high in sensory processing sensitivity, a personality trait marked by stronger reactivity to both external and internal stimuli, may be especially vulnerable. Research suggests they experience heightened emotional sensitivity and may face greater risk in socially painful situations like exclusion.26PubMed Central. Sensory processing sensitivity and social pain: a hypothesis and theory For these individuals, the same empathic wiring that makes them deeply attuned to others can become a liability without deliberate strategies to recover.
Empathizing Changes With Age
The two components of empathizing follow different trajectories across the lifespan. Older adults generally show lower cognitive empathy than younger adults, meaning they struggle more with understanding others’ thoughts and perspectives. However, their emotional empathy remains stable and in some studies is even higher.27PubMed Central. Impact of Aging on Empathy: Review of Psychological and Neural Mechanisms At the neural level, the insula and anterior mid-cingulate response to others’ pain declines with age, while brain activity tied to perceiving someone else’s intentions remains intact.28PubMed. Aging is associated with changes in the neural circuits underlying empathy
This split creates an interesting profile. An older adult might feel as deeply moved by a grandchild’s distress as a younger parent would, perhaps even more so, yet find it harder to take the perspective of someone with very different experiences. The practical result is that cognitive empathy may benefit from deliberate exercise in later life, much as other cognitive abilities do.
Training the Empathic Brain
One of the more striking findings in empathy research is that targeted mental training produces measurable changes in brain structure, not just behavior. A nine-month intervention in healthy adults showed that training in socio-affective skills like compassion and dealing with difficult emotions induced cortical thickening in frontoinsular regions, while training in socio-cognitive skills like perspective-taking changed inferior frontal and lateral temporal cortices. These structural changes correlated with behavioral improvements in the same individuals on domain-specific tests.29PubMed Central. Structural plasticity of the social brain: Differential change after socio-affective and cognitive mental training
Mindfulness-based practices have similarly been shown to increase cortical thickness in the right insula and somatosensory cortex, and the growth in right insula thickness correlated with reductions in alexithymia, that difficulty identifying and labeling one’s own emotions that interferes with empathizing.30PubMed Central. Neurobiological Changes Induced by Mindfulness and Meditation: A Systematic Review The evidence points to empathizing as a set of skills with genuine neuroplasticity, not a fixed personality trait you either have or do not.
Fiction, Screens, and Empathizing at a Distance
Reading literary fiction has a small but measurable effect on empathic abilities. In one experimental study, people who read a fictional story and became emotionally absorbed in it showed increased empathy a week later, while those who were not transported into the narrative actually showed decreased empathy. Nonfiction did not produce either effect.31PubMed Central. How does fiction reading influence empathy? An experimental investigation on the role of emotional transportation Separately, literary fiction specifically has been shown to outperform both nonfiction and science fiction in improving mentalizing, the ability to infer others’ mental states, as measured by tasks involving false-belief understanding and reading emotions from faces.32PLoS ONE. The Use of “Literary Fiction” to Promote Mentalizing Ability The mechanism seems to depend on emotional engagement, not just exposure to characters, which is why simply reading any text does not work.
Digital communication adds another layer. Research on daily digital communication time and empathic tendencies found a non-linear, inverted U-shaped relationship: as daily digital communication rose from zero, empathic tendencies increased, peaking at roughly seven and a half hours per day, after which they declined. The effect sizes were small, suggesting the relationship is real but modest.33ScienceDirect. Development of digital empathy: Non-linear relationships between daily digital communication time and digital empathic tendencies The pattern hints that moderate digital interaction may support empathic engagement while excessive screen time starts to erode it, though this is still an early area of study.
Can Artificial Intelligence Empathize?
Large language models can generate responses that look empathic, and in some cases people rate those responses as genuinely helpful. But across nine studies involving over six thousand participants, AI-generated empathic responses that were labeled as coming from a human were rated as more empathic, more supportive, and more emotionally positive than the identical text labeled as AI-generated. Even when participants merely suspected that AI had helped craft a human-attributed response, perceived empathy dropped. The effects were strongest for responses that emphasized emotional sharing and care, and people consistently preferred human interaction when seeking emotional engagement.34Nature Human Behaviour. Comparing the value of perceived human versus AI-generated empathy
Beliefs about the AI matter too. When people were primed to believe an AI had a caring motive, they perceived it as more trustworthy, more empathic, and better-performing, and this priming effect was stronger for more sophisticated models.35Nature Machine Intelligence. Influencing human–AI interaction by priming beliefs about AI can increase perceived trustworthiness, empathy and effectiveness What this suggests is that empathizing, from the receiver’s perspective, is not just about the quality of the words. It hinges on the belief that there is someone on the other end who is genuinely feeling something. An AI can produce a technically accurate empathic response, but the lack of a sentient agent behind it changes what the response means to the person hearing it. As AI becomes more embedded in therapy chatbots, customer service, and health coaching, this gap between the form and the felt reality of empathizing is going to become an increasingly live question.
