25 Best Mind-Blowing Questions
The best mind-blowing questions make you think hard about the world. Try bringing one of these questions up with a group of people to see what everyone else thinks about them!
- Is water wet?
The debate around this question can get surprisingly heated, and it ultimately depends on how you define “wet.”
Those in the “no” camp typically argue that “wet” means “to saturate with a substance,” in which case, no, water is the substance itself and is not saturated with water.
Those who would answer “yes” to this question typically argue that “wet” means “made of liquid or moisture.” If that’s your definition, water is primarily wet because it is liquid.
- Can you ever really know what you look like?
After all, you only see reflections, photographs, or videos of yourself. All of which are two-dimensional representations of what you look like.
- If a tree falls and no one hears it, does it make a sound?
It would create sound waves, but do they need to hit an eardrum and be interpreted as a sound for a falling tree to “make a sound”?
- If someone learns from a mistake, was it a mistake?
What’s the difference between a learning opportunity and a mistake?
- Do you ever think about how when you look at your reflection in the mirror, you’re looking at the result of thousands and thousands of years of procreation and combining genetics?
You know how people will say, “You look just like your father,” or, “You have your grandma’s smile”? Well, what if you look just like your great-great-great-great-great-grandfather, but you don’t know it?
- How do we know what day of the week it is?
You know how you sometimes get mixed up and spend half the day thinking it’s Thursday, only to find out it’s Tuesday? Before things were digitized, who kept track of these things, and how do we know they didn’t get mixed up at some point?
- Why do people think in different ways?
Some people think more in images while others believe in words—which are you?
- How did the alphabet get put in the order it’s in?
Why are all the vowels and consonants mixed in with one another? When you think about it, it’s a pretty random organizational system.
- Where does the phrase “the whole nine yards” come from?
The more you think about it, the less it makes sense. It doesn’t make sense to reference golf, football, or any other spot. Some theories for where it originates from our fabric measurements, machine guns, or ships—but no one seems to know.
Yale University librarian Fred R. Shapiro once described it as “the most prominent etymological riddle of our time.”
- Did you know that the word “muscle” comes from the Latin term that means “little mouse”?
“Muscle” is derived from the Latin word “musculus,” which translates to “little mouse.” So, next time you flex, think about the ancient Romans who thought it looked like a lot of little rodents.
- Did you know that you can use peanuts to make dynamite?
More specifically, peanut oil, when extracted, can be turned into glycerol. You can then use Glycerol to make nitroglycerine, a substance used in dynamite. Glycerol is a common ingredient in soaps, hand creams, and various food products.
- Did you know that temperature affects the strength of a magnet?
If you heat a magnet, it loses its strength. Meanwhile, when magnets are cold, they’re significantly stronger. Is that why people often put magnets on refrigerators?
- Why do people have different phobias?
If something is more life-threatening, like heights, why doesn’t everyone experience acrophobia? On the other hand, why do some people experience koumpounophobia or the fear of buttons?
- Why does the English language have so many homonyms?
A homonym is when two words sound the same but are spelled differently and have different meanings.
Here are some common examples of homonyms in English:
- Write a synonym to scribble and right, or correct
- Aisle, a pathway or passage, and I’ll, meaning “I will”
- Feat, an achievement, and feet, plural of foot
- How many times can you subtract 10 from 100?
Only once, the second time, you would be subtracting 10 from 90.
- What is the opposite of fire?
Is it non-fire or water?
- What breaks as soon as you say its name?
Silence—by the way, have you ever wondered why sometimes silence feels nice and other times silence is awkward. Read all about it in this article on awkward silence.
- How much can a person change their behavior or personality?
Most people have areas they’re working on—tardiness, laziness, becoming more compassionate, or other aspects of oneself. However, how much can one truly change? Is personality pretty much set, or can you change how you see things with some work?
- Do people have free will to make their own conscious choices, or is life mostly predestined?
Do things like the judicial system make sense if people have limited free will? If someone was predestined by their circumstances to steal, for example, was it their own conscious choice to do so? If not, should they suffer consequences when they do?
- If you gradually replace the planks of a wooden boat one by one, by the end of the process, will you have a new ship?
Think about it, did you renovate your old boat or gradually get a new ship?

If people didn’t die, how many people would be currently living on Earth?
- Can money buy happiness?
Is there a certain amount that can buy happiness?
- What starts and ends with an “e” and only has one letter?
- If people learn from making mistakes, why do we consider mistakes a bad thing?
What’s a mistake that you’ve learned something valuable from? If you could go back in time and not make that mistake but also not learn from it, would you change the past?
- If Pinocchio said, “My nose will grow now,” what would happen?
If it doesn’t grow, that will make the statement a lie, which should cause it to grow, making the statement true.

While learning what friends and family have been up to recently is valuable and essential, it can also be interesting to venture into conversations that help you see how people think about the world.
Here are some times and places you can use a mind-blowing question:
- Over dinner or coffee with your partner. Once you’ve had a chance to hear how your partner’s day is going, try asking them one of these questions! It can help you see how they think about the world and be a fun way to learn more about them.
- While on a road trip with friends or family. Do you have a couple of hours ahead of you in the car? Turning on an audiobook can be a great option, but it can also be fun to chat with the people you’re driving with. Try asking one or two of these questions and see if the people in your car engage with them. You can feel the vehicle’s vibe and opt for silly or more philosophical questions.
- If you work in the public service industry, choose a question and let people vote on the answer with their tips.
