You meet someone new. They mention they just got back from a trip. You ask where did you go? They say Japan. You nod and say cool. Silence.
You want to be more curious. You want the conversation to flow. But you draw a blank on what to ask next — and that blank feels like a character flaw.
It’s not. Curiosity is a skill with specific, trainable moves. And as it happens, it’s the single highest-leverage move in conversation.
The finding that should be better known
In 2017, researchers at Harvard ran a series of experiments on what makes people likeable after a conversation with a stranger. The answer was almost embarrassingly simple.
People who ask follow-up questions — questions that build on what the other person just said — are rated as significantly more likeable than those who ask unrelated questions or pivot topics.
Not more questions. Not cleverer questions. Follow-ups. The move that says I heard that thing you said, and I want to know more about it.
The effect is large enough to hold up across speed-dating, online chat, and real-world first meetings. And yet, when the same researchers counted questions in recorded conversations, they found that most people ask startlingly few. Two or three for a fifteen-minute exchange is common. Most of those are topic pivots, not follow-ups.
So the move that reliably makes people like you, trust you, and remember you — is also one most people never learn.
The follow-up hierarchy
Follow-up questions aren’t all equal. There’s a shape to how they go deeper, and naming it helps you notice where you usually get stuck.
Level 1 — Facts
Where did you go? How long were you there? Who did you go with?
These are fine. They gather information. They rarely build connection on their own, because they’re the questions anyone would ask.
Level 2 — Experience
What was the best part? How did it compare to other trips you’ve taken? What surprised you most?
Now you’re asking for evaluation, not just information. You’re inviting the other person to share what mattered to them. This is where conversations start to feel like conversations instead of interviews.
Level 3 — Meaning
What did you take away from that? How did that change how you see things? What did that experience teach you about yourself?
These ask for meaning. Not everyone wants to go here with everyone, and that’s fine — but when the moment allows it, level-3 questions build closeness faster than any other move in conversation.
Research by Arthur Aron famously showed that gradually escalating self-disclosure between strangers can produce closeness matching people’s closest relationships — in just 45 minutes. The trick isn’t depth from the start; it’s gradual reciprocity. Level 1, level 2, level 3, each side taking turns going slightly deeper.
The three-question rule
Most conversations die because we ask one question, get an answer, and reach for a new topic. Try this instead.
Ask three follow-up questions on the same thread before changing topics.
Where did you go? → Japan. What was the best part? → The food in Osaka. What stood out about the food? → Nothing came from a bag — everything was made fresh to order. Did you try making any of it at home when you got back?
Look at what just happened. You went from a stranger to a person who might tell you about the thing they love. Four questions. No cleverness. Each one built on the previous answer.
The tell me more backup
Sometimes you genuinely don’t know what to ask. Use this:
Tell me more about that.
It’s honest. It’s simple. It works almost every time. Pair it with a specific prompt if you want to aim the attention:
- Tell me more about why that mattered.
- Tell me more about how that felt.
- Tell me more about what happened next.
One thing this does that most beginners miss: it shows the other person you were listening to their answer, not waiting for your turn to talk. That’s the whole game.
Curiosity vs. interrogation
There’s a thin line between curious and nosy. It’s usually not the questions — it’s the intent.
You’re being curious when:
- You’re actually interested in the answer
- You’re listening, not queuing up your next question
- You’re willing to share something back
You’ve crossed into interrogation when:
- You’re running a mental checklist
- You’re not processing what they say
- It feels like an interview, not a conversation
The cure is reciprocity. A good rough rule: after three follow-ups on their thread, offer something of your own — a reaction, a related story, a preference. Then hand it back to them. You want the conversation to breathe both directions.
The quiet habit nobody notices
Here’s the thing about follow-up questions: nobody ever walks away from a conversation thinking wow, that person asked great follow-ups. They walk away thinking that person was really easy to talk to.
The skill is invisible. The effect is enormous.
Practise this week
Pick one conversation — a friend, a colleague, a coffee-shop regular — and apply the three-question rule once.
- Ask an opening question about something light.
- Before you change topic, ask three follow-ups on the same thread.
- Notice how they respond. Most people visibly soften when someone actually pulls at what they said.
Bonus: notice how you feel. Less pressure to be interesting. More relaxed. That’s the quiet kindness of curiosity — it takes the spotlight off you.
In Sation, curiosity is one of five things scored after each session. You’ll get specific feedback on your follow-up pattern — whether you dug deeper or pivoted too soon. See how it works.
