You are mid-conversation at a bar in Shoreditch, laughing at something they have said, when it happens. The shift is instantaneous and total: the way they hold their pint, the cadence of their laugh, the slightly too-eager nod – each gesture, moments ago charming, now triggers a visceral, full-body recoil. You have caught “the ick.” The term has saturated dating discourse so thoroughly that it barely requires definition. Yet its psychological architecture – what it reveals about us, our partners, and the evolutionary wiring beneath our screens – remains stubbornly underexplored, as our earlier investigation into sudden disgust in relationships suggested. A 2025 study from Azusa Pacific University, published in Personality and Individual Differences, has begun to dismantle the phenomenon, and the findings are more unsettling than any dating app algorithm would have you believe.
A Lexicon for Revulsion
The ick is not new. Researchers Brian Collisson, Eliana Saunders, and Chloe Yin traced the concept to a 1995 episode of Friends – “The One with the Ick Factor” – before it was abbreviated on Ally McBeal in 1998 and popularised by Love Island UK in 2017. TikTok supercharged it in 2020, transforming a vague cultural feeling into a searchable, shareable genre. As Saunders, a graduate student at Azusa Pacific University, told PsyPost: “We found references to this phenomenon on social media and TV shows dating back to the mid 90s.” She added that the idea crystallised for her when a friend “kept a running list on her phone notes app of every ick she’d ever experienced from a guy – it was several pages long.”
But the ick is more than a meme. The research team’s pilot analysis of 86 TikTok videos tagged #theick revealed that physical appearance accounted for just 6% of triggers. Behaviour and personality dominated: publicly embarrassing oneself, using annoying speech, and gender-incongruent mannerisms topped the list. Women were disproportionately concerned with misogynistic behaviour and fashion faux pas; men fixated on perceived vanity and excessive trend-following. The findings upend a common assumption – that the ick is shallow. It is, in fact, a deeply selective mechanism, and understanding what it selects for requires pulling apart three distinct psychological threads.
The Personality Triad
The main study surveyed 125 single adults, measuring disgust sensitivity, narcissism, and other-oriented perfectionism against self-reported ick experiences. The results were striking: 64% of participants had experienced the ick, with women (75%) significantly more likely than men (57%) to have felt it. Among those who had, a quarter ended the relationship immediately; a further 42% ended it later.
Each personality trait predicted ick behaviour differently. Disgust sensitivity – the tendency to recoil at stimuli like germs or bodily fluids – correlated with both the likelihood and frequency of ick episodes. Narcissism, specifically the grandiose variety, predicted likelihood but not frequency, suggesting narcissists are selective rather than indiscriminate rejecters. As co-author Dr. Marcus Quinn has noted elsewhere, narcissists “seek idealised mirrors of themselves – a partner’s flaw, like wearing outdated trainers, threatens their self-image, prompting disgust as a defence.” Other-oriented perfectionism – imposing rigid standards on others – predicted both likelihood and frequency, making it the most potent ick amplifier.
This distinction matters. Not all icks are equal. A person high in disgust sensitivity might recoil at a partner’s table manners but remain otherwise content; a perfectionist will find new targets daily. As Saunders cautioned: “Before dumping a partner because their feet dangle when they sit in a chair, we should think critically about why we’re feeling ‘icked’ out. Is this something I truly can’t deal with, or am I being overly critical?”
Gender, Evolution, and the Selective Gaze
The gender disparity in the study aligns with evolutionary theories of parental investment. Women, bearing greater reproductive costs, may have evolved to be more discerning about mate quality. This does not make women “pickier” in a trivial sense; it suggests a calibrated sensitivity to cues signalling unreliability, poor hygiene, or social incompetence. The ick, in this framing, is not pettiness – it is ancient threat-detection running on modern hardware.
Yet the triggers themselves reveal something distinctly contemporary. Women’s ick responses were amplified by perfectionism and narcissism in the domains of public embarrassment and physical appearance – suggesting that social media has grafted new anxieties onto old instincts. Men’s responses, particularly those high in disgust sensitivity, clustered around speech habits and trend-following, hinting at anxieties about status and authenticity that have little to do with Palaeolithic survival.
Dr. Gary Lewandowski Jr., a relationship psychologist and author of Stronger Than You Think, has observed that the ick can function as both signal and distortion. Writing in Psychology Today, he noted that while some ick responses help people identify genuine incompatibilities – such as misogynistic behaviour – others “may reflect socially shaped aversions with little relevance to long-term compatibility.” The challenge is distinguishing between the two in the moment, when the body’s alarm system is already screaming.
The Attachment Dimension
A 2022 study in Frontiers in Psychology added another layer: people with avoidant attachment styles often cope with intimacy by magnifying minor flaws in their partner, lowering relationship satisfaction in the process. This maps directly onto ick dynamics. The ick may function as a distancing tool – a way to re-establish emotional safety when vulnerability becomes intolerable.
This has particular resonance in the age of dating apps, where the biology of desire collides with the architecture of rejection. A 2026 systematic review published in European Psychologist found that anxious attachment was consistently associated with more frequent dating app use and higher levels of problematic engagement, while avoidant attachment produced mixed but often problematic patterns. The swipe model – endless choice, zero commitment – is tailor-made for ick amplification. Every minor flaw becomes an exit ramp. Every quirk becomes grounds for dismissal.
Jennie Rosier, an associate professor at James Madison University, has studied TikTok’s influence on Gen Z dating norms and found that the ick has become “a widely accepted justification for abruptly ending relationships.” Her research highlights how the talking phase and situationships, amplified by platforms like Snapchat, allow individuals to maintain emotional distance while enjoying the validation of romantic interest. The result is a generation that yearns for deep connection while simultaneously erecting barriers to intimacy.
When the Ick Misfires
The evolutionary argument is seductive but incomplete. If the ick once protected us from unreliable mates, it now misfires with alarming regularity. Snapping at a partner’s nasal laugh may stem from ancestral fears of social ostracisation, not genuine incompatibility. Aversion to a partner’s culinary preferences might echo ancient anxieties about food scarcity. In a modern context, these responses become noise – false alarms from a system calibrated for a world of scarcity, pathogens, and small tribal groups.
This is where the research becomes genuinely provocative. Collisson, Saunders, and Yin caution that experiencing the ick does not necessarily lead to better relationship decisions. Their data showed that while some icks identified meaningful incompatibilities – misogyny, reckless behaviour – others targeted trivialities like how someone chases a ping-pong ball. The ick, they argue, may promote “a rejection mindset that undermines dating success.”
The social contagion effect compounds the problem. If consuming media about others’ icks makes you more likely to experience them – a question Saunders flagged for future research – then TikTok is not merely documenting a phenomenon but manufacturing one. Each #theick video is both report and instruction manual, teaching viewers what to find repulsive. The algorithmic amplification of revulsion creates a feedback loop: the more ick content you consume, the lower your threshold for dismissal.
Living with the Alarm
The solution is not to suppress the ick – evolutionary psychologists would rightly caution against overriding deep-seated threat-detection systems. Nor is it to act on every episode. The Azusa Pacific researchers recommend a disciplined approach: pause and identify the physical cues, differentiate genuine threat from trivial quirk, and communicate with curiosity rather than condemnation. As Saunders put it: “While this feeling of disgust could be a valid marker of mate incompatibility, it could also be a symptom of high sensitivity to disgust, narcissism, other-oriented perfectionism.”
The ick is, ultimately, a diagnostic tool – not a verdict. It tells you something is activating your nervous system. What it does not tell you is whether that activation reflects a genuine threat or a misfire shaped by personality, attachment wounds, and an algorithmic culture that rewards instant dismissal over patient inquiry. In a dating landscape designed to optimise for novelty and speed, the ick may be the most dangerous feature of all – not because it is wrong, but because it feels so spectacularly, undeniably right.
