Somewhere in a trend report meeting in 2026, someone said the words "chemRIZZtry" out loud, in a professional context, and got a nod instead of a raised eyebrow. It joins "curveball-crushing" as this year's official term for a phenomenon that is, respectfully, as old as attraction itself: you meet someone who is not your type, on paper, at all — and then you like them anyway.
Chicago has its own extremely specific version of this problem, and it hides inside a sentence most Chicagoans say without thinking twice: "what neighborhood are you in?" Lincoln Park, Wicker Park, Logan Square, West Loop — each one comes pre-loaded with an entire personality, a rent bracket, and an unspoken verdict on whether you're worth the L ride, before anyone's actually met the person attached to the zip code.
So we ran the numbers.
📋 The Trend, As Reported
Nationally, 42% of singles report connecting with someone genuinely outside their usual checklist — the "curveball-crushing" stat. In Chicago, we'd argue the real number is quietly higher, for a very Chicago-specific reason: the "type" most Chicagoans describe out loud isn't a personality. It's a neighborhood.
"He's very West Loop" isn't a comment on someone's character — it's shorthand for a rooftop-bar, restaurant-row income bracket. "She's a Logan Square girl" isn't really about her taste in art — it's a craft-brewery, thrifted-jacket aesthetic filter, applied before a word has been exchanged. Chicago's neighborhoods have such distinct, well-documented identities — Lincoln Park's young-professional lakefront crowd, Wicker Park/Bucktown's creative scene, Logan Square's emerging arts crowd, West Loop's restaurant-and-finance set — that most Chicagoans have effectively replaced "my type" with "my neighborhood," and never noticed the swap.
🚇 Why the L (and the River) Makes This Worse (Or Better, Depending)
Every city we operate in has some version of this. Chicago's runs on a rivalry most locals will insist isn't really about geography, and is entirely about geography: North Side versus South Side, a divide so old it predates dating apps by a century and still quietly decides who ends up on whose radius.
Layer the L on top of it. A trip that looks short on a map — Logan Square to the South Loop, say — can mean two transfers and a wait on a windy platform, which means most Chicagoans' actual dating pool isn't "Chicago." It's whichever three or four L-adjacent neighborhoods they've unconsciously decided are worth the trip, usually all clustered on the same side of the river and the same side of the city they already live on. That radius does more filtering than any stated "type" ever could. If your actual chemistry lives in Bridgeport and your entire dating life has quietly organized itself around the Blue Line, the algorithm didn't reject that connection — the CTA map did, silently, before either of you existed to each other.
It's not a coincidence that Chicago is one of the cities where singles are most visibly rejecting the algorithm entirely in 2026 — trading endless swiping for curated introductions and in-person events with actual intention, per recent Chicago dating coverage. A room that pulls people from across the North and South Sides in a single night breaks the neighborhood-and-river filter on purpose, instead of leaving it to whichever L line happens to run near your apartment.
📊 What the Data Actually Shows
This is where it stops being a vibe and starts being a dataset.
At every MyCheekyDate Chicago event, attendees privately rate each conversation on a five-tier scale, with selections staying open until midnight and zero visibility into who picked whom in the moment. Nobody is performing open-mindedness for anyone else in real time, which produces something a self-reported "would you date outside your usual type?" survey never can: honest, revealed behavior, uncontaminated by the desire to sound less like a West Loop snob to a stranger with a clipboard.
Across our full national Smart-Card dataset — 26,000+ verified events, 65+ cities, 19 years, with Chicago among our longest-running markets — the same pattern shows up every time we look: 86% of attendees leave with at least one mutual match, averaging 2.3 per event, and a meaningful share of those matches are people the attendee would not have predicted from their stated preferences at the door. This mirrors the exact mechanism we've documented in our age-preference data, where the tightest stated filters produced the lowest match rates, and "open" attendees consistently beat the average.
Chicago also has a wrinkle worth naming honestly: in the prime dating-age bracket, the city skews meaningfully female, with roughly 6,620 more single women than men among 25-to-29-year-olds, per 2025-2026 local dating research. In a market with that kind of imbalance, a neighborhood-shaped "type" filter isn't just limiting — it's actively working against the math. The room format solves a specifically Chicago version of the chemRIZZtry problem: it's the only structure in this city built to override both the North/South divide and the neighborhood sort in the same four minutes, at a moment when narrowing the pool further is the last thing the math suggests you should do.
🌆 The Chicago-Specific Cases Where It's Real (and Where It's Just the Blue Line)
In fairness to the skeptics: not every Chicago "curveball" is profound. Some of it is just two people at the same event being pleasant to each other because it's January, the wind off the lake is doing something personal, and neither one particularly wants to wait twenty extra minutes for a transfer. That's not evidence anyone's type theory was wrong. That's evidence the CTA occasionally functions as a matchmaking service by process of elimination, which, arguably, is also a very Chicago insight.
The distinction our hosts notice across thousands of Chicago rotations: a genuine chemRIZZtry moment produces a mutual match both people are visibly surprised by — the "you're a South Side guy and I still want to see you again" conversation on the way out. The wind-chill version produces a polite four minutes nobody selects afterward, neighborhood crossover or not. The Smart-Card only records the former, because it only records what people actually chose once the rent bracket, the river side, and the "I'm just not really a Wicker Park person" instinct were all set aside for four real minutes.
(Honest caveat, the way we treat every number we publish: we can tell you the aggregate pattern holds across our Chicago events — stated preferences diverge from revealed selections, consistently. We can't tell you, for any single match, whether it was genuine chemRIZZtry or just two people relieved to be inside. Strong compass. Not a script.)
💛 One Last Cheeky Thought
Somewhere in this city right now, someone is telling a friend over a Malört-adjacent cocktail that they "never" date South Siders, using the word "never" with the total conviction of a person whose last real relationship started, provably, at a Bridgeport bar their friend dragged them to.
That's not a personality flaw. That's just what a "type" is in a city organized by rivers, sides, and L lines: a story assembled from geography, told with total confidence, updated only when a real conversation — in a room that didn't ask which side you're from — forces the update. Chicago has more opportunities than most cities to get that update, especially with the math currently favoring rooms over apps. Most Chicagoans just never end up in the room where it happens.
Call it chemRIZZtry if you want. We'll call it crossing the river and living to tell about it.

A Note on Methodology
National baseline figures (86% mutual match rate, 2.3 average matches per event) reflect the full Smart-Card dataset across all markets, weighted toward the most recent 24 months where sample size allows; Chicago is included as one of MyCheekyDate's longest-running markets, but the figures above are presented as national, not Chicago-isolated, numbers. Stated-versus-revealed preference patterns are drawn from comparing pre-event stated attributes against private Smart-Card selections. Chicago-specific demographic and cultural figures (51.5% female population in the dating-age bracket; the ~6,620-person gender gap among 25–29-year-olds; distinct neighborhood identities in Lincoln Park, Wicker Park/Bucktown, Logan Square, and West Loop; the shift toward curated, in-person introductions) reflect third-party 2025–2026 local dating and demographic reporting, not MyCheekyDate-collected data, and are cited as general market context rather than proprietary findings. MyCheekyDate was founded in 2007 and has run 26,000+ verified events over the last 10 years across 65+ cities, including Chicago. Full Smart-Card methodology available at mycheekydate.com/smart-card.
