TL;DR
People who ask more questions are consistently liked more, and the right types of questions can build measurable intimacy in under an hour.
The question-asking effect
In 2017, a team of Harvard researchers led by Karen Huang published a study that confirmed something your grandmother probably already knew: people who ask more questions are more likable. But the study went further than folk wisdom, and the specifics are worth paying attention to.
Huang and her colleagues analyzed over 300 online conversations and more than 100 speed dates. The pattern was consistent across both contexts. People who asked more questions during speed dates were significantly more likely to get a second date. The effect was surprisingly precise: asking just one additional question per date yielded, on average, one more "yes, I'd see you again" from the other person.
But here's the part most people miss. Not all questions are created equal. The researchers categorized questions into four types: introductory questions ("Where are you from?"), mirror questions ("What about you?"), full-switch questions (changing the topic entirely), and follow-up questions ("What was that like?").
Follow-up questions were the most powerful by a wide margin. They signal that you're actually listening, that you care enough to dig deeper, and that you're tracking the conversation rather than waiting for your turn to talk. A follow-up question says: I heard you. Tell me more.
This matters for couples because the same dynamic plays out in long-term relationships. The novelty of a new partner fades, and what remains is either genuine curiosity or comfortable autopilot. The couples who keep asking follow-up questions — who stay interested in each other's inner world — are the ones who report higher satisfaction years down the road.
Dr. John Gottman's research at the University of Washington backs this up. He found that couples in stable, happy relationships make what he calls "turning toward" bids for connection 86% of the time. A follow-up question is one of the purest forms of turning toward.
Why questions create closeness
In 1997, psychologist Arthur Aron and his colleagues published a study that became one of the most famous experiments in relationship psychology. They paired strangers together and had them work through 36 questions that gradually increased in personal depth. After 45 minutes, the pairs reported feeling closer to each other than many people feel with lifelong acquaintances. One pair from the study later got married.
The study is often simplified into the idea that there are 36 "magic questions" that create love. That misses the point. The mechanism isn't any specific question — it's progressive self-disclosure. The questions start light ("Would you like to be famous?") and end deep ("If you were to die this evening with no opportunity to communicate with anyone, what would you most regret not having told someone?"). The gradual escalation is what builds trust and intimacy.
This maps directly onto Social Penetration Theory, proposed by Irwin Altman and Dalmas Taylor in 1973. They described relationships as having layers, like an onion. Early interactions stay at the surface — factual, safe, low-risk. As trust builds, people disclose more, moving toward their core values, fears, and vulnerabilities.
Altman and Taylor observed that this penetration happens along two dimensions: breadth (the range of topics you discuss) and depth (how personal those topics get). Healthy relationships expand in both directions over time. Questions are the primary vehicle for that expansion.
The practical implication is clear. If you want to deepen your relationship, you don't need a grand gesture or a weekend retreat. You need a consistent practice of asking questions that go slightly beyond what's comfortable — and being willing to answer them honestly yourself.
For a deeper look at Aron's experiment and how to use those specific questions, see our guide to the 36 questions.
Deep conversations and happiness
In 2010, Matthias Mehl and his colleagues at the University of Arizona published a study that tracked people's daily conversations using a device called the Electronically Activated Recorder (EAR). It sampled 30-second snippets of ambient sound throughout participants' days, capturing the texture of their real conversations — not what people remembered or reported, but what actually happened.
The findings were striking. On average, only 17.9% of participants' conversations qualified as small talk, while 35.5% were substantive. The happiest participants in the study had roughly one-third less small talk and twice as many deep, substantive conversations compared to the unhappiest participants.
Mehl was careful to note that the study couldn't prove causation — it's possible that happier people seek out deeper conversations, or that deeper conversations make people happier, or both. But the correlation was strong and consistent.
What counts as a "substantive" conversation? Mehl defined it as any exchange that involved meaningful information about the speakers or their world, as opposed to trivial chatter about weather, schedules, or surface observations. Conversations about values, experiences, feelings, ideas, and personal stories all qualified.
This has direct implications for couples. If the majority of your conversations with your partner are logistical — who's picking up the kids, what's for dinner, did you pay that bill — you're living in small talk territory. You're not building the kind of conversational depth that correlates with well-being.
The fix isn't to eliminate logistical talk (you still need to figure out dinner). It's to make room for the other kind. A single substantive question during dinner can shift a 10-minute meal from logistics to connection.
Three types of questions that build connection
Not every question is a connector. Some questions open doors; others shut them down. Here's what the research and clinical practice say about the most effective types.
Follow-up questions
As Huang's research showed, follow-up questions are the single most powerful type. They demonstrate active listening and invite deeper disclosure.
Instead of: "How was work?" Try: "You mentioned that project was stressing you out last week. How did the presentation go?"
Instead of: "Did you have fun with Sarah?" Try: "What did you and Sarah end up talking about?"
Specificity is what makes these work. A follow-up question references something your partner actually said, which means you have to be paying attention. There's no shortcut.
Switching questions
These redirect the conversation to a deeper or adjacent topic. They're useful when a conversation has stalled at the surface or when you sense there's more beneath what your partner just said.
Instead of: "That's cool." Try: "What made you think about that?"
Instead of: "Sounds like a tough day." Try: "When you have days like that, what do you actually need from me?"
Switching questions take courage because they're an invitation to go somewhere unscripted. You don't know what your partner will say. That's the point.
Mirror questions
"What about you?" is wildly underrated. When your partner asks you something, answering and then turning it back creates mutual disclosure, which is the foundation of Aron's 36-question experiment.
If your partner asks: "What's something you've been thinking about lately?" After answering, you say: "What about you? What's been on your mind?"
This creates reciprocity. Aron's research showed that mutual self-disclosure builds intimacy faster than one-directional sharing. Both people have to be in the pool.
Questions that kill connection
Worth knowing what shuts conversations down, too.
Yes/no questions: "Did you have a good day?" gives your partner an easy out. "Good" is a complete answer, and most tired people will take it.
Rhetorical questions: "Why would you do that?" isn't actually a question. It's a judgment in disguise.
Interrogative stacking: "Where did you go? Who was there? What time did you leave? Why didn't you text me?" This isn't curiosity. It's surveillance. Your partner will feel cross-examined, not connected.
If you notice yourself defaulting to these patterns, it's worth pausing and reformulating. Swap "Did you have a good day?" for "What was the best part of your day?" Same topic, entirely different conversation.
How to ask better questions
Knowing the theory is one thing. Actually changing how you ask questions at 7 PM on a Tuesday when you're both tired is another. Here are concrete practices that work.
Open vs. closed
This is the single highest-leverage change you can make. Closed questions ("Did you...?", "Was it...?", "Are you...?") invite one-word answers. Open questions ("What...", "How...", "Tell me about...") invite stories.
| Closed | Open |
|---|---|
| Did you have a good day? | What was the best part of your day? |
| Are you stressed? | What's weighing on you right now? |
| Was dinner good? | What did you think of that new recipe? |
| Do you want to talk about it? | I noticed you've been quiet. What's going on? |
You don't need to use open questions exclusively. But if you catch yourself asking three closed questions in a row, switch to an open one and see what happens.
Timing matters
The worst time to ask a meaningful question is the moment your partner walks through the door. Dr. John Gottman calls this the "stress-reducing conversation," and he recommends saving deeper questions for after both partners have had a chance to decompress — usually 20 to 30 minutes after arriving home.
The best times for deeper questions tend to be:
- During meals (phones away)
- On walks
- In bed before sleep
- On car rides
Basically: any time there are few distractions and neither person is in task mode.
Space matters
After you ask a question, stop talking. This is harder than it sounds. Most people fill silence within 3-4 seconds. But meaningful answers often take longer to formulate. Give your partner 8-10 seconds before you jump in with a follow-up or rephrase.
Some of the best conversations happen in the pauses. Silence isn't emptiness. It's processing time.
Don't interrogate, be curious
There's a fine line between curiosity and interrogation, and your partner can feel the difference immediately. The distinction comes down to intent.
Curiosity sounds like: "I'd love to hear more about that." Interrogation sounds like: "But why though? That doesn't make sense."
Curiosity accepts the answer, even if it's unexpected. Interrogation pushes until it gets the "right" answer. If you find yourself asking more than two follow-up questions on the same topic without sharing anything yourself, you've likely crossed from curiosity into interrogation. Share something back. Make it a conversation, not an interview.
Start where you are
If you and your partner aren't used to asking each other meaningful questions, don't leap straight to "What's your deepest fear?" That's like going from the couch to a marathon.
Start with questions that are one step deeper than your current default. If you usually ask "How was your day?", try "What's something that happened today that you're still thinking about?" It's a small shift with a big effect.

FAQ
Can you ask too many questions?
Yes — but it's rare in most relationships. The more common problem is asking too few. That said, Huang's research did note that the positive effect of question-asking plateaus at a certain point, and asking questions without self-disclosing can feel one-sided. The sweet spot is mutual: you ask, they answer, they ask, you answer. If you notice your partner looking overwhelmed or giving increasingly short answers, that's a signal to share something about yourself instead. For more on how to balance sharing and asking, see our guide to emotional intimacy.
What if my partner answers everything in one word?
One-word answers usually mean one of three things: the question was closed (fix: make it open), the timing is wrong (fix: try later), or your partner has learned that longer answers lead to conflict (fix: that's a bigger issue worth exploring, possibly with a therapist). Start by fixing the first two. Ask an open question at a relaxed moment and see if the pattern changes. If it doesn't, it's worth having a direct conversation: "I've noticed we don't talk much about things that matter. I want to change that. What do you think?" See our article on what to do when your partner won't open up for more strategies.
Do these techniques work for long-distance relationships?
They work even better. Long-distance couples don't have the luxury of physical proximity, so their entire connection runs through conversation. Huang's research was partly conducted in online conversations, and the question-asking effect held strong. For long-distance couples, having a daily question ritual — one meaningful question each day, both partners answer — can become the backbone of maintaining emotional intimacy across distance. It gives you something to look forward to and something to talk about beyond "how was your day." Consistency is everything: same time, every day, no skipping. For tips on building better communication habits, check out our guide to communicating better.
Questions are how relationships grow. The research is consistent: asking more, asking better, and leaving room for honest answers leads to stronger relationships. You don't need a PhD. You need genuine curiosity and the willingness to hear the answer, whatever it is.
If you want a structured way to build this practice, Aperi sends you and your partner one question every day, calibrated to your relationship's depth. It handles the "what to ask" part so you can focus on the conversation.
