People share the 18 things that are a 'subtle sign' someone is really smart

"They effortlessly communicate complex concepts in a simple way."

Albert Einstein

One of the strangest things about being human is that people of lesser intelligence tend to overestimate how smart they are and people who are highly intelligent tend to underestimate how smart they are.

This is called the Dunning-Kruger effect and it’s proven every time you log onto Facebook and see someone from high school who thinks they know more about vaccines than a doctor.

The interesting thing is that even though people are poor judges of their own smarts, we’ve evolved to be pretty good at judging the intelligence of others.

“Such findings imply that, in order to be adaptive, first impressions of personality or social characteristics should be accurate,” a study published in the journal Intelligence says. “There is accumulating evidence that this is indeed the case—at least to some extent—for traits such as intelligence extraversion, conscientiousness, openness, and narcissism, and even for characteristics such as sexual orientation, political ideology, or antigay prejudice.”

Reddit user Gisgiii posed a question to the AskReddit subforum: “What is a subtle sign that someone is really intelligent?”

The answers painted a clear picture of how smart people behave: They tend to be great communicators who understand their audience and are more concerned with getting things right than being right.

Here are 18 of the best answers.

1. They draw wisdom from multiple sources.

"They draw wisdom from multiple sources. Wait but that might be more wise than intelligent... But I guess those two tend to be seen together a lot," — Puzzlehead-Engineer

2. They know their audience.

"They can switch up the way they talk to match the person they're talking to without sounding condescending. They listen to how others learn and explain it in that person's language of understanding," — Wynonna99

3. They develop a keen sense for their job.

"I used to work with a doctor - Tom Howard - and the day I realized he was a genius was the time he guessed every single condition a patient of mine had based on minute pieces of information about him," — Yodei_Mon

4. Curiosity.

"They are curious about everything. To be intelligent you need to be knowledgeable and you can't be knowledgeable if you are never curious," — soup54461

5. They're great at conveying ideas.

"When they explain something they make you feel intelligent," — gwoshmi

6. Considerate questions.

"They spend time thinking before asking a question," — ParkMan73

7. They make hard ideas simple.

"They effortlessly communicate complex concepts in a simple way," — joculator

8. They know what they don't know.

"They know when their knowledge ends and say something to the extent of 'i don't know and anything else i say on this topic is ignorant speculation,'" — blutoboy

9. They ask great questions.

"They can ask really good questions."

"Edit: to anyone not understanding what mean, I’m talking about people who ask “really good questions”, not just any questions, really good ones. I don’t know how one would achieve this skill(I know I haven’t)," — milkmanbran

10. They don't pretend to know everything.

"They aren’t afraid to say they don’t know the answer to a question," — xchernx

11. They change their minds with new information.

"They admit to changing their mind about something," — FarAwayAdventure

12. They pivot well.

"They apply knowledge from one realm into a new and relevant situation," — soubestitch

13. They are open-minded.

"They can genuinely consider an idea which opposes their worldview without necessarily accepting it," — paidshill29

14. They use analogies.

"People who use analogies to explain concepts to others. It’s a form of code-switching and integrating concepts on the fly and is a clear indicator someone is both socially and conceptually intelligent," — SwimmerAutomatic2488

15. They don't argue.

"I think intelligent people are more willing to calmly debate/discuss, rather than argue. Like, you explain to them why you disagree, and they listen to you and ask further questions about your viewpoint before offering a different perspective; as opposed to an unintelligent person, who would just resort to insults when other people disagree with them," — AngelicCinnamonBun

16. They learn from mistakes.

"Admitting when they're wrong and being willing to learn from mistakes," — siyl1979

17. A sense of humor.

"Humor. I think that truly funny people are often very smart and cognizant of the different ways an idea can be humorous on several levels. They also know their audience. I think the difference between say a Jeff Foxworthy and a Dave Chappelle and a Bo Burnham is their audience and their interests," — biscuitboi967

18. A love of learning.

"They say they love learning and they learn something new every day. Then they listen more than talk," — throwingplaydough

Ontario teen says he'll live in 'modular home' invention for a year to prove it can end homelessness

He's already invented a wooden car.

Ribal Zebian is going to test a house he designed by living in it for a year.

Ribal Zebian, a student from the city of London in Ontario, Canada, already made headlines last year when he built an electric car out of wood and earned a $120,000 scholarship from it. Now, he's in the news again for something a little different. Concerned with homelessness in his hometown, Zebian got to work creating a different kind of affordable housing made from fiberglass material. In fact, he’s so confident in his idea that the 18-year-old plans on living in it for a year to test it out himself.

Currently an engineering student at Western University, Zebian was concerned by both the rising population of the unhoused in his community and the rising cost of housing overall. With that in mind, he conjured up a blueprint for a modular home that would help address both problems.

Zebian’s version of a modular home would be made of fiberglass panels and thermoplastic polyethylene terephthalate (PET) foam. He chose those materials because he believes they can make a sturdy dwelling in a short amount of time—specifically in just a single day.

“With fiberglass you can make extravagant molds, and you can replicate those,” Zebian told CTV News. “It can be duplicated. And for our roofing system, we’re not using the traditional truss method. We’re using actually an insulated core PET foam that supports the structure and structural integrity of the roof.”

Zebian also believes these homes don’t have to be purely utilitarian—they can also offer attractive design and customizable features to make them personal and appealing.

“Essentially, what I’m trying to do is bring a home to the public that could be built in one day, is affordable, and still carries some architecturally striking features,” he said to the London Free Press. “We don’t want to be bringing a house to Canadians that is just boxy and that not much thought was put into it.”

Beginning in May 2026, Zebian is putting his modular home prototype to the test by living inside of a unit for a full year with the hope of working out any and all kinks before approaching manufacturers.

“We want to see if we can make it through all four seasons- summer, winter, spring, and fall,” said Zebian. “But that’s not the only thing. When you live in something that long and use it, you can notice every single mistake and error, and you can optimize for the best experience.”

While Zebian knows that his modular homes aren't a long-term solution to either the homeless or housing crisis, he believes they could provide an inexpensive option to help people get the shelter they need until certain policies are reformed so the unhoused can find affordable permanent dwellings.

What to buy for the homeless at the grocery store. 🛒 Most people get it wrong. After being there myself, these are the survival items that actually matter 💯 The 2nd to last one is about more than survival—it’s about DIGNITY. We are all one circumstance away from the same shoes 🙏 SAVE this for your next grocery run. 📌 IG@hardknockgospel Substack@ Outsiders_Anonymous #homelessness #helpingothers #kindness #payitforward #learnontiktok

Zebian’s proposal and experiment definitely inspires others to try to help, too. If you wish to lend a hand to the unhoused community in your area in the United States, but don’t know where to look, you can find a homeless shelter or charity near you through here. Whether it’s through volunteering or through a donation, you can help make a difference.

Doctor reveals the 1-minute daily hack that can radically improve public speaking skills

It all starts with putting a pen in your mouth.

Want to speak better? Put a pen in your mouth.

Ever been told that you mumble? Or that your way of speaking is quiet or lacking confidence? It could be affecting you in a range of situations, from asking someone out to giving a presentation at work or interviewing for a job. Well, a behavior researcher has a solution for you: put a pen in your mouth.

Behavior expert and speaker Dr. Shadé Zahrai shared a technique in a social media video that could help people who mumble, rush through speeches, or generally struggle to enunciate when speaking aloud. She recommends taking a clean pen and placing it horizontally in your mouth, like a horse biting a bridle. Then take out a book and read it aloud to yourself for one minute, even overpronouncing some words if you need to. After a minute has passed, take the pen out of your mouth and continue reading the rest of the page. Doing this "Pen Drill" once a day should help you speak more clearly and effectively overall.

@shadezahrai

I promise you - so this for 60 seconds and you’ll enunciate better.

This may sound silly, but there's solid reasoning behind it. Because you're trying to hear yourself clearly while speaking with a pen in your mouth, you naturally slow down as your mouth opens wider than usual. This makes your speech and enunciation clearer by forcing you to slow down and articulate each word. A side benefit is that speaking slowly and enunciating clearly makes you appear more calm, confident, and authoritative.

@joseczuniga

Try this pen trick to enunciate better and get a deeper more confident voice #josezuniga

There are additional benefits beyond clearer speech. Content creator Jose Zuniga claims the technique can help men deepen their voices. Zuniga says that when men speak from their chest rather than their throat during the "Pen Drill," the wider mouth opening allows them to speak at a lower pitch than usual. Singers and vocal coaches also recommend putting a pen in your mouth in order to reduce vocal strain.

@sophiesaidcoaching

A tip guarenteed to help with vocal strain!! Just grab a pen or a chopstick #vocalcoach #singing #singer

Speaking clearly is incredibly beneficial, not only because it helps you be understood and get what you want, but also because it makes you appear more eloquent and intelligent. Speaking in a clear, calm way makes you sound confident, which helps people believe your words and arguments more than if they were delivered meekly, filled with "ums" and "uhs." Combined with strong body language, it can mean the difference between being believable and being believed.

"Clear speech signals calm authority, and calm authority is magnetic," explains Zahrai in her video. "You don't sound rushed, you don't sound unsure, you sound like someone who expects to be listened to."

@gentlemens_collective

To be become a better speaker FAST… slow down.

If you want to improve your speech, whether to reduce mumbling, slow a rushed, worried pace, or sound more confident, put a pen in your mouth and swallow your pride (but not the pen!). With time and practice, it could change your speech patterns into ones people clearly understand and feel compelled to listen to.

Mom realizes she's been using the 'heavy' setting on her washer wrong for years—and fellow moms are shook

"Today years old when I realize why my blankets are sopping wet."

Stay-at-home mom Catrina shares shock at learning what the 'heavy' setting on her washer means.

Knocking out loads of laundry is a feeling of accomplishment that is unmatched. Depending on what needs to be washed, washing machines offer a variety of settings for the ideal clean. But even the most seasoned laundry pros can admit that they don't fully understand how to use them properly.

One stay-at-home mom shared her funny and relatable washing machine mistake. Catrina (@granolabarpan) got the shock of a lifetime when she realized that she had been using the "heavy" setting on her washer wrong for years.

"POV: today years old when it clicks why my blankets are sopping wet!!! I thought HEAVY meant heavy items being washed," she wrote in the video's overlay.

"Heavy on my machine means heavily soiled," she went on to add in the comments. "I thought it meant the stuff I was putting in the machine was heavy in weight/pounds."

Some moms are also realizing this for the first time. "Ok.. so I am 66 years old learning this???!! I always thought that heavy meant weight also😂," one person commented. Another person wrote, "Well I was today years old when I learned what heavy meant too…😂"

Others expressed confusion with so many settings, and reminiscing on simpler times. "Wait a minute. 😂. I think I need to for once go and read the manual because I have been wondering about all of the options," another user wrote. And another chimed in, "I want my old $250 3 options hot/warm/cold on/off washer back. It didn’t die it rusted out but took 25yrs to do it. I had 5 kids, plus my ex in-laws living with me."

Washing machine settings, explained

Struggling to understand the settings on your washing machine? You're not alone.

"Knowing these settings helps avoid common laundry mistakes, such as using the heavy cycle for heavy fabric weight instead of heavy soil, which can lead to ineffective cleaning or damage over time," Vanessa Ruiz, a professional organizer at Sparkly Maid San Antonio, tells Upworthy.

These are five washing machine settings and how they work:

1. Normal/Regular Cycle
Ruiz explains that this is your typical setting for day-to-day loads such as t-shirts, jeans, sheets, and underwear.

"These laundry loads are typically washed in warm water and the setting is rinsed with medium spin speeds through agitation in order to properly clean moderately soiled garments," she says. "This cycle is safe enough to wash a variety of different fabric content with a somewhat dirty load."

2. Delicate/Gentle Cycle
Ruiz notes that the delicate cycle is created specifically for delicate fabrics—lingerie, silk, lace, or embellished clothing—that may become damaged in a normal or regular wash.

"This cycle will use moderate spin speeds through gentle agitation to thoroughly dry clean and not damage clothes too easily," says Ruiz. "This is the preferred cycle when laundry items that require extra care or are labeled 'delicate' or 'hand wash' need to be washed."

3. Heavy Duty Cycle
The heavy duty cycle is specifically for heavily soiled items like work clothes, kitchen towels, and bedding.

"This setting uses higher water temperatures, longer wash times, and powerful agitation to remove stubborn dirt and grime. It’s perfect for those tough laundry jobs, but not recommended for delicate fabrics," explains Ruiz.

- YouTube www.youtube.com

4. Bulky/Bedding Cycle
This cycle is often confused with "heavy."

"This cycle accommodates larger, heavier items that absorb a lot of water, such as comforters, pillows, and sleeping bags," says Ruiz. "It uses more water, medium spin speeds, and longer wash times to thoroughly clean bulky items without causing damage or imbalance."

5. Quick Wash
In a rush? This is the perfect setting to use.

"It is an accelerated wash cycle designed for small loads of lightly soiled clothes, usually lasting 15 to 40 minutes," says Ruiz. "It’s great for when you need clean clothes fast and can save energy compared to longer cycles."

People share tips from housekeepers that they do to keep their homes organized and clean.

Keeping a clean house is not easy. Approximately 21% of Americans report that they find cleaning tasks overwhelming according to a survey from the American Cleaning Institute, and approximately 10% of Americans enlist extra help to keep their homes spotless from housekeepers, notes the Home Cleaning Centers of America.

In an online discussion about cleaning tips on Reddit, people shared the most impactful housekeeping advice they've gleaned from housekeepers that have helped them keep their homes not just clean, but free from clutter.

"When I think of a clean home, it’s not just a wiped down surface; it’s tidy, organized, decluttered and presentable," one person wrote. "These tips contribute to the feel of a tidy, intentional and presentable home."

- YouTube www.youtube.com

These are 18 helpful housekeeping tips that will help you keep your home orderly and sparkling clean.

"I wrap my phone charger through my bed frame so it’s always easy to grab. It used to just hang on the ground. It was life changing when I first got into bed and saw my housekeeper did this for me." - Bubbly_Picture_9876

"I open ALL blinds and curtains. I used to clean but keep it pretty dim, but opening ALL blinds makes a huge difference! Feels so much cleaner immediately." - Bubbly_Picture_9876

"[Having a handheld vacuum]. LIFE CHANGING!!! Taking out the vacuum was a pain so I did it when crumbs would accumulate. Having a small one in the kitchen drawer makes it so easy, so I don’t mind quickly vacuuming crumbs and dirt whenever I see them." - Bubbly_Picture_9876

"Wipe down the bathroom surfaces with toilet paper before cleaning to get the dust up. Then clean. So much quicker. Even better - cut a small piece of a disposable duster off and use it to dust the toilet first. It works SO well and gets in the weird nooks and crannies of the exterior toilet where dust and whatnot accumulates." - Advanced-Public4935, dodie437

"I worked as a housekeeper for a while and picked up the habit of vacuuming the bathroom before cleaning anything. It picks up dust, hair, and any other miscellaneous things you might not want to grab with bare hands." - iufgv

"Baseboards wiped with a dryer sheet 🙏🏻." - dphiloo

- YouTube www.youtube.com

"LIGHT SWITCHES! It’s the first thing I notice in homes and I would say in general one of the big 'blind spots' for people. And refrigerator and oven handles, wipe daily with a damp micro fiber and you’ll notice such a nicer feeling grabbing them." - ccoopp10

"Scrub the door that goes from the house to garage. It is usually filthy, and we rarely think of it cuz guests don’t usually use it." - ExpressionKey2820

"I have a step to climb to get into my bed. My ladies put my slippers there. It made me feel cared for, like when I was a child." - Lily_V_

"I clean off the counters / wipe them down, then sweep, BEFORE doing the dishes. I always get water on the floor while doing dishes and then either mess up my broom / sweeping bc it’s wet or have to get on my hands and knees to clean up the water and waste paper towels or a dirty up a towel. So my order goes: counters, sweep, dishes, mop." - Sanch0panza

"Dishwashing soap to clean my glass shower stall." - wildblueberry9

"Dusting & disinfecting the underside of the toilet. So between the seat and the floor. So many people miss this area and it's like night and day. Most don't notice dust there because you'd have to get up close to see it, or deliberately look at the underside of the toilet, but once it is dusted you can tell right away from a distance. The whole bathroom feels so clean." - DaisyFart

"Invest in a steam cleaner. It cleans everything." - iNerdRage

"I found some cable clips that I love for my cell phone, iPad, and watch charging cables. They’re attached to the side of my nightstand. Go to Amazon and search for 'cable clips.' Then I can find the charging cable I need within reach." - blueSnowfkake

"When my fridge starts running low on food and I’m purging I do a quick inside wipe down / sink wash of a couple of fridge shelves and also wipe down the inside and around the fridge." - No-Rush8716

"I also got some rubber gap covers that cover the slit in between the stove and counter. It’s been a game changer because it keeps that spot clear. It use to drive me crazy to clean and stuff would stuck in there all the time." - No-Rush8716

"My last cleaning crew used a mop that had clips. They could attach microfiber or other cloths to use depending. I couldn't find exactly the model they used but found one on Amazon called Mr. Siga. I buy 50 packs of terry shop cloths at Costco and similar packs of microfiber cloths. They all fit on the head of this mop. For me, these are so much better than Swiffers. I use a spray bottle with all purpose cleaner dilution when I'm doing the floors. It also works much better than a broom when dry." - gripping_intrigue

"I keep a dish scrubber brush in the shower, and in the soap reservoir of it I use 1/2 cleaning vinegar and 2/3 dish soap. Once a week while I'm in the shower I can scrub the shower down while I'm in it and it makes it so much easier. Got it from a housekeeper on Tiktok." - tatertots8sunburns

The one sign that someone is highly intelligent, according to author Oscar Wilde

Of course, he said it with his signature wit.

A woman carrying books and writer Oscar Wilde.

People are quick to point out when someone has changed their mind on a topic, whether it’s in the political world, where switching sides on an issue makes you a flip-flopper, or in our personal lives. When a friend suddenly changes their mind on an important issue, we become skeptical of their motives or whether they even have any genuine beliefs in the first place.

Are we a little too harsh on people who change their views? Don’t intelligent people change their minds when presented with new information, while those who are more interested in protecting their ego cling to incorrect ideas even more strongly?

Oscar Wilde on intelligence

Legendary author, humorist, and raconteur, Oscar Wilde, sang the praises of those who can freely change their mind in an 1885 piece on painter James McNeill Whistler in The Pall Mall Gazette of London. “Consistency is the last refuge of the unimaginative,” he famously wrote.

Dr. Emma Jones, a physician and burnout coach, elaborated on Wilde’s quote in a recent viral Instagram post. She agrees that the ability to change your mind is a hallmark of brilliance.

“Here's how you know someone is highly intelligent: It's not their degrees. It's this. It's what led Oscar Wilde to say that ‘consistency is the last refuge of the unimaginative.’ What he meant by that was that highly intelligent people know how to change their minds,” Jones says. Jones goes on to say that intellectually gifted people use phrases such as “I used to think,” or “That's a good point, let me reconsider.”


Jones adds that mental flexibility is a sign of strong character. “Most people double down to protect their ego. But intelligent people update their beliefs. They get more curious instead of more defensive,” Jones continues. “They don't tie their identity to being right. And they treat being wrong like data, not humiliation.”

Oscar Wilde had no problem with people who changed their mind

Wilde firmly believed that people should be mentally flexible and had zero issue with those who were wildly inconsistent in their views, as long as they were charming. “The well-bred contradict other people. The wise contradict themselves,” he wrote in 1894’s Phrases and Philosophies for the Use of the Young.

He’s got a point. Who's to say that we all have to carry around rigid worldviews and must be consistent 100% of the time?

Adam Grant, an organizational psychologist and author of Hidden Potential: The Science of Achieving Great Things and Think Again: The Power of Knowing What You Don't Know, also believes that being able to change your mind is a hallmark of intelligence.

“A sign of intellect is the ability to change your mind in the face of new facts. A mark of wisdom is refusing to let the fear of admitting you were wrong stop you from getting it right. The joy of learning something new eventually exceeds the pain of unlearning something old,” Grant wrote on Twitter.

Ultimately, maybe inconsistency isn’t a personal flaw but a way of adapting to a world constantly in flux. Those who lack imagination cling to their strongly-held views, while the wise continue to change. Great thinkers and psychologists agree that changing your mind shouldn’t be seen as a weakness but as a sign of a strong mind and character.
