A red flag is a behavior that tells you how someone is likely to treat you later. Not a quirk, not a bad day, a signal. They show up everywhere people do: dating, friendships, family, roommates, work, school and online. The behaviors are the same. Only the costume changes. Here's how to recognize them in each place, and the one rule that matters more than any list.
A red flag is an observable behavior that predicts harm: to your safety, your autonomy, your money, your reputation or your sense of what's real. It's called a flag because it's a warning you can see before the thing it warns about arrives.
Red flags are about behavior you've witnessed, not vibes, rumors or someone's reputation. And they're about patterns. One red flag is a conversation. A pattern is an answer. Almost everyone shows a red flag once. The question is what happens when you name it.
If they were obvious, nobody would need a page about them. Three things get in the way:
You never see the pattern in a single moment. You see a comment, then a week later a different comment. Each one is small enough to explain away, and by the time they add up you've already invested.
Love bombing feels like being adored. Possessiveness feels like being wanted. A boss who texts at 11pm "because you're the only one I trust" feels like being valued. The red flag is inside the compliment.
Nobody wants to be the person who overreacts. So you give the benefit of the doubt, again, and the person who benefits from your doubt learns exactly how much they can get away with.
The highest-stakes context, because romance is where control hides best. Dating red flags are mostly about how someone handles the word no, and what they do with your attention once they have it.
Not a red flag: wanting to see you a lot, being nervous, having an ex, disagreeing with you. The flag is never the feeling. It's what they do when you set a boundary.
Cray's CrayScore™ measures 74 of these behaviors across 18 categories, and SchemerScore™ looks specifically for ulterior motives.
Friendship red flags get ignored longest because there's no breakup to force the question. You can drift in a bad friendship for years.
Not a red flag: a friend who's busy, who forgets things, who needs more from you during a hard season. The flag is a pattern of taking that never turns around.
More on this, including how to help a friend see a red flag in their own relationship, on Cray for friends.
The hardest context, because you didn't choose these people, you can't easily leave, and the behavior usually predates your ability to name it. Family red flags are often the original template for every other one you'll tolerate.
Not a red flag: parents who worry, siblings who annoy you, relatives who disagree with your choices but respect them. The flag is when your autonomy is treated as an attack.
Parents reading this: Cray for parents is about the other direction, helping your student see red flags for themselves.
You share a lock, a lease and a fridge with this person. Roommate red flags are the ones that cost money and sleep, and the best time to catch them is before you sign.
Not a red flag: different schedules, different cleanliness standards, a bad week. The flag is refusing to negotiate any of it.
Screening questions and what to do about the roommate you already have: Cray for roommates. Free printables for residence halls: housing safety flyers.
Workplace red flags come from bosses, coworkers and the culture itself. The tricky part is separating a hard job from a harmful one. Demanding is fine. Manipulative is not.
Not a red flag: a tough deadline, direct feedback, a boss who is stressed. The flag is a pattern where the stress is always yours to absorb.
Honest limits on what an app can and can't do about a workplace, including when to go to HR: Cray for work.
Campus is where most people meet the most new people they ever will, fast, with less supervision than they've ever had. The red flags overlap with dating and friendship, with a few that are specific to the setting.
Not a red flag: intensity, new friends who want a lot of your time, traditions you find weird. The flag is any pressure that makes your no cost you something.
Cray partners with campuses on exactly this: see Cray for campuses, Greek life programming and Cray Protected venues.
Screens remove the cues you'd normally rely on and add a few new ways to lie. Online red flags are mostly about mismatches: between what they say and what they'll show, between how fast they move and how little they've earned.
Not a red flag: someone who's slow to reply, awkward on camera, or private about their last name early on. The flag is pressure plus a story that doesn't hold still.
Cray's BaeScore™ measures the green flags that online red flags imitate, and ConvoScan reads a screenshot when you want a second opinion fast.
Lists like the ones above are useful for one thing: giving you words for what you already noticed. They can't tell you what to do, because a single item on any list is not an answer. What turns a red flag into a decision is what happens after you name it.
Plainly, without a speech. "When you went through my phone, that wasn't okay." You're not accusing. You're observing.
Healthy people get it, even if they're embarrassed. Unhealthy people make the conversation about how you brought it up, or about something you did, or about how much they've sacrificed.
If the behavior returns, it's not a moment anymore. It's a pattern, and patterns don't need another chance to prove what they are.
Knowing what to run from is half of it. The other half is knowing what to look for, because a red flag often imitates a green one: possessiveness looks like devotion, love bombing looks like being chosen. Green flags are quieter. Consistency between words and actions. Respect for a no. Comfort with your other relationships. Owning mistakes without a performance. Cray measures both sides on purpose; a red flag check alone makes you paranoid, a red-and-green check makes you literate.
Heavy topic, light delivery. Cray built a universe around red flags so the lessons stick.

Red flags in social situations
Parties, group trips, nights out, the friend of a friend. These are the red flags you see in the first hour, before you know someone's name, and they're the most reliable of all because nobody is performing for you yet.
Not a red flag: loud, awkward, drunk, boring. The flag is anyone whose fun requires someone else's discomfort.
Practice calling these in a room full of people: Red Flag or Nah?, the game.
