Psilocybin and Social Connection: What the Research Shows

Psilocybin, Social Anxiety & Social Connection

0 emotional blunting with psilocybin

In a 2025 head-to-head comparison, escitalopram reduced brain responses to emotional stimuli. Psilocybin showed no such reduction and may preserve or enhance emotional processing, a key mechanistic distinction from SSRIs.

In 2025, Jungwirth and colleagues published the first clinical study to directly measure empathy changes in a patient population after psilocybin treatment.^[1] The finding was more specific than most of the "psilocybin increases empathy" claims circulating in popular media: psilocybin significantly increased both explicit and implicit emotional empathy in patients with major depression, compared to placebo. Cognitive empathy and moral reasoning showed no significant change.

That distinction matters. Emotional empathy is the felt sense of sharing another person's emotional state. Cognitive empathy is the intellectual capacity to understand what another person is thinking or feeling without necessarily feeling it yourself. Psilocybin shifted one and left the other alone. That is a precise, testable finding rather than a vague claim about "feeling more connected."

This article covers what psilocybin does to interpersonal perception: the specific changes in emotional processing, the brain mechanisms behind them, how they differ from what conventional antidepressants produce, and why those changes may matter for social connection and anxiety. For the broader anxiety evidence base, see our pillar on psilocybin for anxiety.

The Jungwirth 2025 Finding: What Happens When You Measure Empathy Directly

Most claims about psilocybin and empathy come from surveys and self-reports in healthy volunteers. Jungwirth and colleagues designed a clinical study to measure the effect directly in patients with major depressive disorder, using validated empathy measures before and after psilocybin therapy.^[1]

The finding: psilocybin significantly increased both forms of explicit emotional empathy (consciously recognizing and sharing another's emotional state) and implicit emotional empathy (automatic, pre-reflective emotional resonance) compared to placebo. These changes correlated with symptom improvement.

What did not change: cognitive empathy and moral reasoning. Participants became better at feeling with other people. They did not become better or worse at reasoning about other people's mental states, nor did their moral decision-making shift in any measurable direction.

This specificity is scientifically valuable. A drug that increased all forms of social cognition indiscriminately would suggest a general activation of social circuits. The fact that emotional empathy increases while cognitive empathy stays flat points to a more targeted mechanism, one that operates on the felt, affective dimension of interpersonal perception rather than the analytical dimension.

Emotional vs. Cognitive Empathy: The Distinction That Makes the Finding Precise

The difference between these two forms of empathy is not just theoretical.

Emotional empathy is what causes a person to feel a pang of distress when someone else is hurt, or to feel genuine joy at another person's good news. It is involuntary, fast, and rooted in the same neural systems involved in the direct experience of those emotions. The insula and anterior cingulate cortex are central to it.

Cognitive empathy is the capacity to model what another person is thinking or feeling without necessarily experiencing it yourself. It is slower, more deliberate, and associated with the temporoparietal junction and prefrontal cortex. It is what allows someone to understand why a friend is upset even when they themselves feel calm, or to predict how a colleague will react to a piece of news.

Depression is associated with reduced emotional empathy and, in some presentations, excessive self-focused cognition that crowds out the capacity to attend to others' emotional states at all. The Jungwirth finding suggests psilocybin specifically restores the affective dimension of that deficiency.

For the neural context of how these changes relate to psilocybin's effects on brain connectivity, see psilocybin and social anxiety: can it help? and the broader research overview at psychedelics and social anxiety disorder.

How Psilocybin Changes the Way You Process Other People's Faces

One of the most concrete findings in the social connection literature comes from Carhart-Harris and colleagues' 2018 study of psilocybin-treated patients with treatment-resistant depression.^[3]

Before treatment, many patients with depression show a well-documented bias toward recognizing negative emotional expressions. Faces that are ambiguous or neutral tend to be read as threatening or unhappy. After psilocybin treatment, this bias shifted: participants showed increased recognition of positive and neutral facial expressions. Their brains were reading social signals differently.

The imaging data from that study gave a neural correlate for this shift: the amygdala, which is the brain's primary threat-detection and emotional evaluation region, showed changed response patterns to emotional stimuli. This aligns with Mertens and colleagues' 2020 finding.^[4]

Mertens found that psilocybin treatment reduced amygdala reactivity to threatening stimuli and increased connectivity between the prefrontal cortex and the amygdala. The prefrontal cortex plays a regulatory role in moderating the amygdala's threat responses. When prefrontal-amygdala connectivity is stronger, the brain's capacity to regulate and contextualize threat is greater. The net result is a brain that is less automatically on guard in social situations.

This is the neurological substrate of feeling safer around other people.

The Prosocial Feedback Loop: Why Empathy Changes May Compound Over Time

Bhatt and colleagues' 2024 review in npj Mental Health Research proposed a model for how psilocybin's empathy effects translate into lasting mental health changes.^[2]

The model works as follows. Psilocybin acutely increases emotional empathy and prosocial warmth. Participants with greater emotional attunement are more engaged and present in their relationships during the integration period after a session. Improved relationship quality reduces the social isolation and interpersonal friction that sustains depressive and anxious states. Reduced depression and anxiety in turn make social engagement feel safer and more rewarding, completing a positive feedback cycle.

This framing reframes empathy changes not as a pleasant side effect but as a mechanism. If the feedback loop is correct, psilocybin's antidepressant and anxiolytic effects depend partly on whether the initial empathy increase is metabolized into actual changes in relational behavior during the integration period after the session.

The Smigielski 2019 RCT of 38 participants provides supporting evidence for the lasting dimension of this process.^[5] Participants who combined psilocybin with mindfulness training showed significantly reduced self-referential processing at four months, compared to mindfulness alone. Self-referential processing, the brain's tendency to route experience through a lens of self-evaluation and self-criticism, is one of the mental habits most corrosive to natural social connection. People who are heavily self-monitoring in social situations are less able to attend to others' emotional states. The lasting reduction in self-referential processing that Smigielski measured may be part of the mechanism through which the prosocial feedback loop gets established.

The SSRI Comparison: Psilocybin Preserves Emotional Processing While Antidepressants Blunt It

One of the most practically meaningful findings in recent research is the direct comparison between psilocybin and escitalopram on emotional processing.

Carhart-Harris and colleagues published a 2025 RCT comparing the two treatments head-to-head on brain responses to emotional stimuli.^[6] Escitalopram reduced brain responses to emotional stimuli, consistent with the emotional blunting that patients on SSRIs frequently report: a reduced ability to feel both positive and negative emotional experiences fully, which patients sometimes describe as "feeling like I'm behind glass." Psilocybin did not reduce emotional responsiveness and may preserve or enhance it.

This distinction matters specifically for social connection. Emotional blunting is not just an abstract side effect. It affects the ability to be moved by a friend's news, to feel genuine pleasure in social interaction, to be fully present in an intimate conversation. Patients who feel emotionally blunted on SSRIs often describe feeling socially disconnected, going through the motions of relationships without fully inhabiting them.

Psilocybin's profile, at least as captured in the Carhart-Harris 2025 comparison, goes in the opposite direction: not toward numbing social experience but toward fuller, more emotionally present experience of it.

Wang and colleagues' 2025 ACS Pharmacology review situates this within the broader context of psilocybin's prosocial mechanisms, including 5-HT2A agonism in social circuits and the overlap between serotonin system function and social behavior.^[7] Wang notes the relevance to autistic adults specifically, for whom both the serotonin system and social behavior circuits show measurable differences. For more on that specific population, see psilocybin and autism-related social anxiety.

The Open Question: Does Empathy Change and Then Fade, or Does It Compound?

The research on psilocybin and social connection is internally consistent but leaves an open empirical question.

Most of the empathy and prosocial findings are measured shortly after treatment: days or weeks, not months. The Bhatt 2024 feedback loop model predicts that empathy changes compound over time through improved relationships, but this longitudinal pathway has not been directly tested in a controlled trial focused specifically on social connection outcomes.

The Smigielski four-month DMN data provides indirect support for lasting change. The Jungwirth 2025 empathy correlation with symptom improvement suggests the changes are clinically meaningful rather than purely experiential. But the mechanism by which a temporary empathy increase becomes a lasting change in how a person navigates social relationships is not yet directly mapped.

This is where the research is heading. The prosocial feedback loop hypothesis is currently testable: a trial measuring empathy, relationship quality, and depression symptoms at multiple follow-up points after psilocybin therapy would answer the question directly. As of 2026, that trial has not yet been published.

The Bottom Line

Psilocybin produces specific, measurable changes in interpersonal perception: increased emotional empathy without changes in cognitive empathy, improved emotional face recognition, reduced amygdala threat-reactivity, and preserved emotional responsiveness in direct comparison to SSRIs. Bhatt 2024 proposes these changes may compound into lasting antidepressant and anxiolytic effects through a prosocial feedback loop. The mechanism is biologically coherent and supported by convergent evidence, but the longitudinal social connection outcomes have not yet been directly tested in a controlled trial.

Frequently Asked Questions

Does psilocybin make you more empathetic?

Psilocybin increases emotional empathy: the felt sense of sharing others' emotional states. In Jungwirth et al.'s 2025 RCT, MDD patients showed significantly higher both explicit and implicit emotional empathy after psilocybin compared to placebo. Cognitive empathy (intellectually modeling what others think or feel) and moral reasoning were not significantly changed. The increase appears to be specific to the affective dimension of empathy rather than a general activation of all social cognition.

How does psilocybin change the way you see other people?

At the behavioral level, Carhart-Harris et al. (2018) found psilocybin improved recognition of positive and neutral emotional facial expressions in depressed patients who had previously shown a bias toward reading faces as negative or threatening. At the neural level, Mertens et al. (2020) found reduced amygdala reactivity to threatening stimuli and increased prefrontal regulation of the amygdala after psilocybin treatment, producing a brain less automatically on guard in social situations.

Can psilocybin improve relationships?

Research suggests psilocybin produces changes that could support improved relationships: increased emotional empathy, reduced self-referential processing, and better emotional face recognition. Bhatt et al. (2024) propose that improved empathy leads to better relationship quality, which in turn sustains the antidepressant and anxiolytic effects of psilocybin through a prosocial feedback loop. This model is biologically coherent, but controlled trials specifically measuring relationship quality outcomes after psilocybin have not yet been published.

Does psilocybin increase feelings of connectedness?

Survey and clinical data consistently report increased feelings of social connection and reduced isolation after psilocybin experiences. The mechanistic basis for this includes reduced amygdala threat-reactivity (Mertens 2020), increased emotional empathy (Jungwirth 2025), and preserved or enhanced emotional responsiveness in comparison to SSRIs (Carhart-Harris 2025). Smigielski et al. (2019) found that psilocybin plus mindfulness produced lasting reductions in self-referential processing at four months, which may be the neural mechanism through which social presence and connection improve.

What happens to your social behavior after psilocybin?

Clinical studies report improved emotional face recognition, increased emotional empathy, and reduced threat-vigilance in social contexts after psilocybin treatment. Qualitative reports from trials consistently note increased feelings of social openness and connection in the weeks following a session. The Bhatt 2024 prosocial feedback loop model proposes that these changes are not merely experiential but mechanistically contribute to lasting antidepressant outcomes. Longer-term social behavior outcomes have not yet been tracked in controlled trials.
