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 beside a comment

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

Once a refugee seeking safety in the U.S., Anita Omary is using what she learned to help others thrive.

True

In March 2023, after months of preparation and paperwork, Anita Omary arrived in the United States from her native Afghanistan to build a better life. Once she arrived in Connecticut, however, the experience was anything but easy.

“When I first arrived, everything felt so strange—the weather, the environment, the people,” Omary recalled. Omary had not only left behind her extended family and friends in Afghanistan, she left her career managing child protective cases and supporting refugee communities behind as well. Even more challenging, Anita was five months pregnant at the time, and because her husband was unable to obtain a travel visa, she found herself having to navigate a new language, a different culture, and an unfamiliar country entirely on her own.


“I went through a period of deep disappointment and depression, where I wasn’t able to do much for myself,” Omary said.

Then something incredible happened: Omary met a woman who would become her close friend, offering support that would change her experience as a refugee—and ultimately the trajectory of her entire life.

Understanding the journey

Like Anita Omary, tens of thousands of people come to the United States each year seeking safety from war, political violence, religious persecution, and other threats. Yet escaping danger, unfortunately, is only the first challenge. Once here, immigrant and refugee families must deal with the loss of displacement, while at the same time facing language barriers, adapting to a new culture, and sometimes even facing social stigma and anti-immigrant biases.

Welcoming immigrant and refugee neighbors strengthens the nation and benefits everyone—and according to Anita Omary, small, simple acts of human kindness can make the greatest difference in helping them feel safe, valued, and truly at home.

A warm welcome

Dee and Omary's son, Osman

Anita Omary was receiving prenatal checkups at a woman’s health center in West Haven when she met Dee, a nurse.

“She immediately recognized that I was new, and that I was struggling,” Omary said. “From that moment on, she became my support system.”

Dee started checking in on Omary throughout her pregnancy, both inside the clinic and out.

“She would call me and ask am I okay, am I eating, am I healthy,” Omary said. “She helped me with things I didn’t even realize I needed, like getting an air conditioner for my small, hot room.”

Soon, Dee was helping Omary apply for jobs and taking her on driving lessons every weekend. With her help, Omary landed a job, passed her road test on the first attempt, and even enrolled at the University of New Haven to pursue her master’s degree. Dee and Omary became like family. After Omary’s son, Osman, was born, Dee spent five days in the hospital at her side, bringing her halal food and brushing her hair in the same way Omary’s mother used to. When Omary’s postpartum pain became too great for her to lift Osman’s car seat, Dee accompanied her to his doctor’s appointments and carried the baby for her.

“Her support truly changed my life,” Omary said. “Her motivation, compassion, and support gave me hope. It gave me a sense of stability and confidence. I didn’t feel alone, because of her.”

More than that, the experience gave Omary a new resolve to help other people.

“That experience has deeply shaped the way I give back,” she said. “I want to be that source of encouragement and support for others that my friend was for me.”

Extending the welcome

Omary and Dee at the Martin Luther King, Jr. Vision Awards ceremony at the University of New Haven.

Omary is now flourishing. She currently works as a career development specialist as she continues her Master’s degree. She also, as a member of the Refugee Storytellers Collective, helps advocate for refugee and immigrant families by connecting them with resources—and teaches local communities how to best welcome newcomers.

“Welcoming new families today has many challenges,” Omary said. “One major barrier is access to English classes. Many newcomers, especially those who have just arrived, often put their names on long wait lists and for months there are no available spots.” For women with children, the lack of available childcare makes attending English classes, or working outside the home, especially difficult.

Omary stresses that sometimes small, everyday acts of kindness can make the biggest difference to immigrant and refugee families.

“Welcome is not about big gestures, but about small, consistent acts of care that remind you that you belong,” Omary said. Receiving a compliment on her dress or her son from a stranger in the grocery store was incredibly uplifting during her early days as a newcomer, and Omary remembers how even the smallest gestures of kindness gave her hope that she could thrive and build a new life here.

“I built my new life, but I didn’t do it alone,” Omary said. “Community and kindness were my greatest strengths.”

quiet, finger over lips, don't talk, keep it to yourself, silence

It can be hard to stay quiet when you feel like you just have to speak your mind. But sometimes it's not a great idea to share your opinions on current events with your dad or tell your boss where they're wrong in a meeting. And having a bit of self-control during a fight with your spouse is a good way to avoid apologizing the next morning.

Further, when we fight the urge to talk when it's not necessary, we become better listeners and give others a moment in the spotlight to share their views. Building that small mental muscle to respond to events rather than react can make all the difference in social situations.

What is the WAIT method?

One way people have honed the skill of holding back when they feel the burning urge to speak up is the WAIT method, an acronym for the question you should ask yourself in that moment: "Why Am I Talking?" Pausing to consider the question before you open your mouth can shift your focus from "being heard" to "adding value" to any conversation.

The Center for The Empowerment Dynamic has some questions we should consider after taking a WAIT moment:

  • What is my intention behind what I am about to say?
  • What question can I ask to better understand what the other person is saying?
  • Is my need to talk an attempt to divert the attention to me?
  • How might I become comfortable with silence rather than succumb to my urge to talk?

The WAIT method is a good way to avoid talking too much. In work meetings, people who overtalk risk losing everyone's attention and diluting their point to the extent that others aren't quite sure what they were trying to say. Even worse, they can come across as attention hogs or know-it-alls. Often, the people who get to the heart of the matter succinctly are the ones who are noticed and respected.

Just because you're commanding the attention of the room doesn't mean you're doing yourself any favors or helping other people in the conversation.

The WAIT method is also a great way to give yourself a breather and let things sit for a moment during a heated, emotional discussion. It gives you a chance to cool down and rethink your goals for the conversation. It can also help you avoid saying something you regret.

How much should I talk in a meeting?

So if it's a work situation, like a team meeting, you don't want to be completely silent. How often should you speak up?

Cary Pfeffer, a speaking coach and media trainer, shared an example of the appropriate amount of time to talk in a meeting with six people:

"I would suggest a good measure would be three contributions over an hour-long meeting from each non-leader participant. If anyone is talking five/six/seven times you are over-participating! Allow someone else to weigh in, even if that means an occasional awkward silence. Anything less seems like your voice is just not being represented, and anything over three contributions is too much."

Ultimately, the WAIT method is about taking a second to make sure you're not just talking to hear yourself speak. It helps ensure that you have a clear goal for participating in the conversation and that you're adding value for others. Knowing when and why to say something is the best way to make a positive contribution and avoid shooting yourself in the foot.

James Van Der Beek's realization about his identity after cancer has people pondering

"I had to look my own mortality in the eye," said the Dawson's Creek alum. "I had to come nose to nose with death."

James Van Der Beek in 2010 and 2023

There's nothing like a brush with death to make you reflect on your life. It's so easy for all of us to get caught up in the day-to-day details of living and not take the time to ponder the deeper elements of existence, from the nature of the universe to the meaning of life to our own individual role in the big picture.

Existential questions can sometimes feel overwhelming, but actor James Van Der Beek shared a thoughtful 48th birthday message with his own life reflection after facing cancer, and it distills a lot of the angst of those questions into a simple yet profound answer that's hitting home with people.


Van Der Beek, who starred in the millennial favorite Dawson's Creek, announced he'd been diagnosed with stage 3 colorectal cancer in 2024 at age 47. He and his wife, Kimberly, have six children, and in a video shared on social media, Van Der Beek shared the progression from his somewhat unfulfilling identity as an actor to "the ultimate" identity as a husband and father prior to his cancer diagnosis.

"I could define myself as a loving, capable, strong, supportive husband, father, provider, steward of the land that we're so lucky to live on," he said. "And for a long time, that felt like a really good definition of the question, 'Who am I? What am I?'"

"And then this year, I had to look my own mortality in the eye," he continued. "I had to come nose to nose with death. And all of those definitions that I cared so deeply about were stripped from me. I was away for treatment, so I could no longer be a husband who is helpful to my wife. I could no longer be a father who could pick up his kids and put them to bed and be there for them. I could not be a provider because I wasn't working. I couldn't even be a steward of the land because at times I was too weak to prune all the trees during the window that you're supposed to prune them."

He found himself facing the question: "If I am just a too-skinny, weak guy, alone in an apartment, with cancer, what am I?"

So often we define ourselves by our roles in life or by what we do, but what if those things change? Who are we when it's just us, alone, with nothing external to anchor us to a particular identity?

"And I meditated and the answer came through," Van Der Beek shared. "I am worthy of God's love, simply because I exist. And if I'm worthy of God's love, shouldn't I also be worthy of my own? And the same is true for you."

I offer that to you however it sits in your consciousness. However it resonates, run with it," he said. "And if the word God trips you up, I certainly don't know or claim to know what God is or explain God. My efforts to connect to God are an ongoing process that is a constant unfolding mystery to me. But if it's a trigger or if it feels too religious you can take the word 'God' out and your mantra can simply be 'I am worthy of love.' Because you are."


Van Der Beek's sincere, warm delivery and universal message of love and worth hit home for a lot of people. Fellow celebrities and fans alike praised and thanked him for it:

"Happy birthday brother. This was absolutely beautiful 💜🙏🏻💜," wrote singer Chris Daughtry.

"You’re a gift to this earth and I’m grateful to know you even if it’s just through IG. Greatly admire the graceful way you share and happy you made it around the Sun again," wrote New Kids on the Block's Joey McIntyre.

The Sopranos' Jamie-Lynn Sigler wrote, "That is it James. That is it. And you my friend are love. A steward of love. A teacher of love !❤️. We love you !!"

"I watched this with Bodhi with tears in our eyes and Bodhi said 'that was really touching' thanks for being love James and sharing that with everyone, ❤️" added actor Teresa Palmer.

Battlestar Galactica reboot's Katee Sackhoff wrote, "Thank you for your vulnerability and wisdom ❤️ Amen!'

"You are such a special soul. You are pure love my friend," added actor Nikki Reed. "Worthy of it all… hoping to hug all of you soon. Happy birthday❤️❤️❤️"

Some people took issue with Van Der Beek saying people could remove the word "God" from the message if they wanted to, but the reality is that not everyone has positive feelings about God or religion, and some have even been deeply hurt by people weaponizing them. Van Der Beek making a message of love more universal so that everyone can take it in and benefit from it without barriers or hang-ups is part of what makes it so beautiful. He was able to express his own religious/spiritual experience without shying away from the terminology that was true for him, while also making sure that his message was accessible to everyone regardless of faith or belief.

Perhaps we can all take a lesson from Van Der Beek's sincere, open, and balanced approach as well.

Gloria the cat strolls in with a pink bow.

If you love a cat video AND surprises, then meet Gloria. This rambunctious little tortoiseshell cat has an entire life so separate from her owner at times, he has to piece together stories from random clues. Said cat guardian is comedian Martin Rizo, who, alongside a few small dogs, has had Gloria for about six years.

In a Facebook Reel, Rizo shared a clip of Gloria returning home from an adventure with a hot pink bow on her head. A chyron initially appears on screen asking, "When you know your cat has other families. She came back with a hair bow."


In the clip, we see Gloria stroll in with a giant hot pink "hair" accessory tied lovingly around her neck. Rizo asks, "Bro. How many owners do you have? How many names do you have besides Gloria? I don't even know who you are! How many families do you have? How many times do you eat per day?"

Gloria is then seen playing with a cat treat on the ground. Rizo continues his line of questioning while giving her gentle head scratches. "Am I your favorite owner?" Gloria then jumps off the couch. "Where are you going? Oh, you're going over there again, huh? Please don't go, wait." At the bottom of the Reel, he asks, "Does your cat cheat on you also?"

The comment section is on fire. Those who have "outside cats" are probably aware that their kitty's adventures often lead them to all sorts of hijinks around town. At over 224,000 likes and nearly 4,000 comments, people have opinions and their own stories.

One hilarious Facebook follower shares, "My cat was in my neighbor's Xmas photo last year. In a 'blanking' Xmas outfit."

Another shares a photo of their black cat dressed in some sort of checkered sweater, saying, "This happened to me this week. The cat came back looking like this. But ready for food."

This person relays that they met the "other" family, writing, "Our cat disappeared for a few days, then came home a couple of days. After this happened a few times, we followed her. This is how we found out she 'adopted' the neighbors. We named her Fancy and the neighbors named her Pepperoni, so she is now Fancy Pepperoni and we share custody."

Upworthy had a chance to chat with Rizo, who explained that Gloria was (and still kind of is) a stray in every sense of the word. "Once a stray, always a stray. So I guess she lives here part time. But I do see her every day, and there are nights she won't come home."

He further explains that Gloria's relationship with the neighbors is also quite special. "I have seen her chilling at the neighbors—sitting on their lap. I do need to follow her one of these days to see where she goes."

Some commenters point out the dangers of not keeping one's cat indoors. One person politely suggests, "Please put a collar on ur kitty so someone doesn’t take her. Edit: to everyone trying to argue that cats can get hurt/caught if they have a collar on… please educate yourself on breakaway collars."

In the article "Are Outdoor Cats Happier?" The Animal Humane Society experts have thoughts. "People who let their cats outside may have the best intentions, but that doesn’t change the outcome of a recent study, which found the average life span of a cat is dramatically shorter for those that roam freely outdoors — by as much as 10–12 years!"

That said, there are some cats who truly take the world as their oyster. Their sense of adventure merely can't be contained with cat nip and a climbing tree. Even the Humane Society accepts that "community cats" exist. They note, "Community cats are un-owned cats that live outdoors in the community. They may be feral or friendly, may have been born into the wild, or may be lost or abandoned pet."

Gloria is neither lost, nor abandoned. Her love is simply too big to give to just one family, and it seems her admirers wouldn't have it any other way.

urine, urinalysis, pee, doctors, medicine, healthcare, wellness, reddit, reddit confessions, weird

A guy says he can tell when he's getting sick based on the taste of his pee. Ancient doctors would probably agree.

A recent Super Bowl ad by the hydration brand Liquid IV urges viewers, with an assist from Phil Collins, to "take a look" at their urine as the color could be a warning sign of dehydration. It's long been known that lighter pee often means you've been drinking more water and other fluids. Darker yellow or amber pee can mean you're not well-hydrated, which forces the kidneys to concentrate the urine, leading to darker colors and a more powerful odor. Crucially, striving for pee that is completely clear isn't ideal.

In short, there's a lot you can learn from pee without any complicated lab tests. But some people take this pee science more seriously than others. A user on Reddit recently went viral for confessing that he's been not only tracking the color and clarity of his own pee for four years, he's been tasting it as well.


- YouTube www.youtube.com

"Every morning for the past four years, I've tasted my own urine. Approximately 5ml, enough for proper palate evaluation," he wrote in a post.

Again, don't try this at home.

"I've developed what I call the Golden Index, a standardized evaluation framework with six primary metrics," he explained, going on to list how he evaluates his urine's color, clarity, sweetness, salinity, bitterness, and mouthfeel each on a five-point scale each morning.

He writes that after a while, he grew sensitive to any slight change in the color, clarity, and yes, especially the taste. Those changes were often a sign of something happening in his body. Most notably, he says that he could tell he was getting sick about three days before feeling any symptoms.
"At approximately month eight, I identified a predictive pattern. When salinity exceeds 4.0 AND a copper/metallic undertone is detected, illness onset occurs within 72 hours. I've now observed this pattern 12 times and eleven predictions were accurate - that's a 91.7% accuracy rate with an average lead time of 68.4 hours before symptom manifestation." He also writes that he could see and taste when he was dehydrated, had consumed alcohol, had eaten red meat, and even when he was overly stressed.

Naturally, the jokes practically wrote themselves over the course of several hundred comments:

"'Hi Mr. Johnson, just wanted to call in sick for my shift on the 19th…' ... 'But it’s only the 16th' swishes profusely around mouth 'Trust me sir, you’re gonna want to find coverage'”

"Please tell me stool isn’t your next experiment"

"I am equally impressed and disgusted by this"

And OP was kind enough to answer the question on everyone's mind: "My wife believes I simply 'take a long time' in the bathroom each morning. She's not aware of the research."

We don't know for sure who this anonymous, and brave, Internet data-nerd is, but modern doctors advise that you should never drink, or even taste, your own urine. But he's not wrong about one thing: Medical professionals used to taste pee all the time.

It's hard to stomach, but the tasting of pee proved to be a crucial step forward in the diagnosing of some illnesses, especially diabetes.

Diabetes was, if not discovered, then at least noticed by the ancient Egyptians as far back as around 1550 BCE. Papers discovered from the time recommended an antiquated treatment for "excessive urination" involving a concoction of pond water, elderberry, milk, and more. A few hundred years later, ancient Indian physicians noted that the urine of people who were sick with this mysterious affliction attracted ants.

It wasn't until 1674 that a doctor named Thomas Willis tasted diabetic urine and couldn't help but notice how sweet it was. "Wonderfully sweet as if it were imbued with honey or sugar," were his exact words. Further experiments would eventually prove that the pee was full of sugar. It took centuries, but, in 1921, the very beginnings of an effective treatment for diabetes began to pop up. The discovery of sugar in urine was an incredible key to understanding the disease.

Doctors had been tasting and visually analyzing urine for centuries in order to detect illnesses. They even had complex charts correlating different colors with potential diagnoses. It was a practice called uroscopy.

Most of it was, respectfully, bunk, and uroscopy became mostly extinct not long after Thomas Wills' discovery. But some elements of it persist today.

Signs of ailments like urinary tract infections, liver failure, and certain kidney issues can be outwardly visible in urine samples upon visual inspection. Doctors will still look for color, clarity, and thickness in their visual exams. But most of the rest of urinalysis is best performed in a lab, where accurate readings on pH levels, protein, glucose, nitrites, and more can tell them far better information.

But as gross as it is, not to mention unsanitary and potentially unsafe, there are crazier ideas out there than the concept that tasting your own pee could alert you to a brewing illness. Ancient Indian and Egyptian doctors would probably agree with this guy.
