Why Do Questions Feel Better Than Answers? A Note on Curiosity

A question feels better than an answer because it is unfinished. The mind leans toward it. An answer closes the loop, and a closed loop asks nothing more of us.

That is the short version. The longer version is more interesting, and it comes with a habit you can start with a kettle.

What is actually happening when a question lights you up?

Some psychologists describe curiosity as the feeling of a gap: you know a little, you sense there is more, and the distance between the two tugs at you. I find this a useful picture, though I hold it loosely. Nobody has the last word on what curiosity is.

Here is why the picture helps. A gap has a direction. When you wonder why the kettle clicks off, your attention has somewhere to go. You look at the kettle differently. You listen to the click and notice the steam.

A finished answer has no direction. It is a place to stand, which is pleasant, but it is not a place to travel from.

Three things tend to be true of a question that keeps you lit:

• It is specific enough to picture.
• It is small enough to look into this week.
• It is open enough that the answer leads somewhere.

Isn't the answer the whole point?

This is the common misconception, and I held it for years. I assumed questions were just the cost of getting answers. You wanted the answer, so you put up with the question for as short a time as possible.

The trouble is that this treats the answer as the prize and the wondering as the waiting room. Many people, me included, find the reverse is closer to true. The wondering is where the energy lives.

That doesn't mean answers are bad. A good answer is a gift. The point is that the best answers behave like doors, not walls. They hand you the next question.

Montaigne, writing in the sixteenth century, took as his motto a short line: What do I know? It is not a boast or a despair. It reads to me as an invitation to keep looking, and I find it a comfortable thing to carry.

A worked example: why does the kettle click off?

Let's take one small question all the way through, to see how an answer can open things up.

The first guess. Most of us assume the kettle clicks off when the water reaches 100°C, so it must contain a thermometer of some sort. It's a sensible guess. In many common kettles, it is not quite what happens.

What many kettles do instead. In many electric kettles, steam is channelled from the boiling water up a small passage toward a switch. Inside the switch sits a bimetallic strip, which is two thin metals bonded together. When the hot steam reaches it, it warms up and bends. The bending flicks the switch, and the power cuts. Click.

Why would a strip bend? Because different metals expand by different amounts when heated. Bond two together and heat them, and one side wants to grow more than the other. The strip has nowhere to go but to curve, a bit like a slice of toast bowing in the toaster. The same idea turns up in simple thermostats elsewhere.

Why the steam, not the water? Steam is a quick, reliable signal that the water is boiling. The kettle is not measuring a number. It is reacting to a consequence of boiling.

Some kettles use electronic sensors rather than a bimetallic strip, so I'd say "many" rather than "all". I'm also still not certain how the details differ between models, and that is a good place to leave a question open.

Look at what happened. One small question about a click gave us:

• a correction to a guess I'd held for years,
• a fact about metals that applies far beyond kitchens,
• a link between physics and everyday objects,
• three new questions. Why do metals expand at all? What else uses bending strips? What would a kettle do at a high altitude, where water boils at a lower temperature?

That last one is real physics, by the way. Water boils at a lower temperature the thinner the air above it. I'd call that a thread worth pulling next week.

How to keep a small list of questions

You don't need an app or a special notebook. I tried a few things before landing on something plain, and I'll come to the failures below.

What works for me is a single page, or the back of an old envelope, headed I wonder. Then:

1. Write the question the moment it arrives. Even half-formed is fine. "Why does the toast pop?" counts.
2. Keep it in your own words. Plain phrasing keeps it alive. A tidy, formal question feels like homework.
3. Aim for ordinary objects and moments. Light on a wall, steam on a window, the sound a gate makes.
4. Don't try to answer yet. A question you have just written is still lit. Give it a day.
5. Don't judge the questions. A "silly" question is often a good one. Silly ones tend to be the ones nobody checked.

Why this works, as best I can tell: writing a question down stops it dissolving. Most of mine used to vanish within minutes. A list turns a passing flicker into something that can be returned to.

Here are some from my own page, to show how modest they can be:

• Why does the kettle click off?
• Why does a wet towel feel colder than a dry one?
• Why does the moon look bigger near the horizon?
• Why do some leaves turn before others on the same tree?

The moon one is a nice example of honest uncertainty. The effect is well known as an illusion, since the moon is not actually larger, but as far as I know there is still no single agreed explanation for why our minds do it. I'd rather tell you that than pretend it's settled.

Look one up each week

Once a week, choose one question from the list and spend about fifteen minutes on it. That's all. The limit matters, and I'll explain why in a moment.

My method:

• Pick the one that tugs hardest. Not the most impressive, just the one you keep thinking about.
• Guess first. Write down what you think the answer is. This is the step I most often skip, and I'm always glad when I don't. A guess makes the real answer land harder, and a wrong guess is more memorable than a right one.
• Read one or two plain sources. A good library book, a decent encyclopedia, an explainer from a museum or a university. If two sources disagree, note it. That is information too.
• Write one sentence of what you found. Then write one new question it raised.

The fifteen-minute limit is there for kindness. Without it, one question becomes a weekend, then a pile of tabs, and then the habit feels like a burden and falls away. A small, regular bite is easier to keep than a big, occasional one.

Some weeks I find nothing satisfying. That's fine. Not every question has a tidy answer, and a question that stays open is not a failure. It just goes back on the list.

Ask them out loud

I'd kept lists privately for a while before a neighbour changed how I used them. Ines lives a few doors down, and she has a habit I first took for a quirk. She wonders aloud. Over the fence, while she waters her tomatoes, she will say something like, "I wonder why the water beads up on this leaf and not that one."

She never says it as a quiz. She isn't looking for the answer from me, and I certainly didn't have one. She just says it and lets it sit between us, and then we both look at the leaf.

I had always treated my questions as slightly embarrassing, as though asking one admitted I didn't already know. Ines showed me otherwise. A question spoken aloud is an invitation. It gives the other person permission to wonder too, and more often than not they'll add a half-idea of their own.

I'm still learning to do this well. I sometimes catch myself rushing to fill the silence with a guess, which spoils the pleasure. But when I manage to simply say the question and wait, the conversation is better for it. Thank you, Ines.

If speaking aloud feels strange, start small:

• Say one to yourself in the kitchen.
• Say one to a friend or family member over tea.
• Say one to a pet. It's good practice, and they never judge.

What didn't work for me

In the interest of honesty, here are the attempts that didn't stick.

• A beautiful notebook. I bought one, and it made me afraid to write anything unimpressive. The envelope works better.
• Daily lookups. Seven a week was too many. I read quickly and retained little. Once a week gave the question room to breathe.
• Looking everything up straight away. The instant answer was satisfying for a minute and gone by evening. Waiting a few days seemed to make the answer stick.

Your results may differ. This is only what worked for me, and you may find a different rhythm suits you better. If a method feels like a chore, change it. The habit is meant to serve the wondering, not the other way round.

A question to carry with you

Here is one I haven't resolved. When a question is answered, do we lose something, or only trade it for a better question? I lean toward the second. Every answer I've enjoyed has left a doorway behind it. But I'm not sure that's always so, and I'd like to notice it over the coming weeks.

So perhaps try this: today, find one small thing that makes a sound, a shadow or a shape, and ask why. Don't look it up yet. Just let it sit for a day and see how it feels to hold a question that's still open.

If you spot something small, I'd be glad to hear about it.
