Confidence is key to a lot of success in life, but it's not some magic solution that allows someone to circumvent reality. However, that has never stopped a certain kind of person who, by the looks of it, makes it their life’s mission to embarrass themselves publicly.
So we’ve gathered some of the best posts from this group dedicated to folks sharing and shaming people who were 100% confident about something they were completely wrong about. Get comfortable as you scroll through, brace yourself for some secondhand embarrassment, upvote your favorite examples and be sure to share your thoughts in the comments down below.

"No Nation Older Than 250 Years"
The ridiculous stupidity of the original post aside, the concept of a “nation” is notoriously vague and tricky to define, considering how many diverse political, geographical, ethnolinguistic, and cultural aspects it attempt to amalgamate. Among all the modern nations, I think China is the closest to passing most antiquity tests. It has definitely been a nation in every sense for at least 3000 years.
The "Confidently Incorrect" subreddit has been around since 2017, and like much of niche internet culture, it was small at first before expanding into a shared belly-laugh of a community. What began as a simple concept, collecting screenshots of people being hilariously, confidently wrong, quickly took off. The internet, of course, is never wanting for people who have strong opinions and thin facts.
The subreddit has grown to hundreds of thousands of users over time and is now one of the default locations for humor that blurs the cringe-comedy line. Its material has a tendency to bleed into the mainstream, showing up on Twitter, TikTok, and Instagram, and sustaining the internet's hunger for this sort of material in general.

Indian Billionaires
Besides the obvious idiocy of confusing Native Americans with the inhabitants of India: since when does the presence of 10 billionaires testify of the wealth of the general population?? A society can have billionaires and still suffer from poverty. Ironically, India is a good example of that.
Oh, Lavern
Seriously. The fact that there are people grown adults with jobs and children of their own who insist they hate pronouns or that we need to get rid of pronouns, etc. absolutely boggles my mind. It’s a part of speech, you literally can’t even say “I hate pronouns“ without using pronouns.
The "Confidently Incorrect" subreddit is one of the darker corners of the internet where there's schadenfreude mixed with humor, and everyone can't help but congregate to stare in awe at how brazenly incorrect someone is. The rules are simple, posts, comments, or screenshots of individuals declaring things with complete and utter certainty, yet being laughably, irrefutably wrong. It's not the mistake that's funny, it's the swagger, the confidence, the complete and utter lack of doubt that turns boring errors into internet gold.

One of the reasons that this type of content is so popular is because it hits a very human frustration, we all know someone in our lives who acts like an encyclopaedia human but speaks absolute muck. Watching random individuals getting publicly roasted for it online is vicarious. It's like seeing the obnoxious guy at the dinner party get fact-checked by the universe itself. There's relief and humor in watching overconfidence get deflated by the world, and that's what makes the subreddit so engrossing.

A second is the uncooked humor of contrast. Someone who says "the moon is nearer than Australia" with unshakeable conviction is not just wrong, he's so wrong it's an artwork. The gap between their conviction and reality is the humor. While a flat-out mistake, coupled with the recognition of ignorance, can be annoying, confidently erroneous posts demonstrate the human tendency to bluff or to pose, and it usually leads to something absurd.

There's also a feeling of communal reassurance. As you scroll through the thread of unapologetically incorrect opinions, you can't help but feel just a little bit smarter by comparison. It's not sinister, exactly, it's more or less a harmless ego stroking. You might not know advanced physics or obscure trivia, but at least you’re not out here insisting with authority that “penguins are a type of plant.” The internet thrives on making people feel like part of an in-group, and laughing together at outrageous errors creates that bond.

Oh my lord....how do you get to be so stupid yet SO convinced you're correct???
Memetic potential plays a big role too. Most assertively wrong posts end up leading lives of their own, becoming jokes that cycle back in other corners of the web. The humor is easy to pass along, easy to understand, and contains low levels of context, great traits for viral content. To that degree, the subreddit is a part of the wider context of internet humor in which screenshots can go from Reddit to Twitter to TikTok, accruing chuckles along the way.

Finally, there is something disconcertingly endearing about fallibility being in action. Sure, it's funny, but it also serves as a reminder that confidence guarantees nothing and that even the most self-assured human can be an utter blunderhead. In a world where misinformation moves fast and individuals double down rather than backing down, there is value in seeing how silly that looks to others.
Rule
Okay, this might be obvious for native daily speakers. But if English is a language you need to learn, the grammar books explain: I, you, he/she/it = singular; we, you, they = plural, plus any variation to indicate relation to persons or objects. For a non-native speaker the only logic to use "their" (as in plural) in above case is: He/she = he or she = 2 options for a person = plural. If the gender is clear, it sounds very odd to use the plural form as in "Joe owns a car. It is their car." A non-native speaker learns "It is his car".

The great thing about maths, and indeed science, is that they don't care whether you agree or not.
The charm of the "Confidently Incorrect" subreddit, then, is a blend of humor, catharsis, and camaraderie. It's a place where egos are deflated, facts prevail, and all the folks scrolling by get to experience just a tiny bit more grounded in their own fallibility, without sacrificing the pleasure of enjoying someone else's absurdity.

Metric System At It Again
Eh, it's complicated. The software was metric because it was easier to code. Anything else was in imperial units. All the Mercury, Gemini and Apollo hardware was designed to specs in inches/pounds. The Shuttle was designed in imperial units, but they were "weird" because most of the design was made in metric units (for integration with international cooperation projects) and then converted to inches; so, they ended up with a lot of 64th in their fractions and plenty of mils on the sensitive stuff (.001 inch). After the 1999 Mars Orbiter f*ckup, all the recent projects (ISS, Artemis, SLS, Orion etc) have been in metric. Some subcomponents are derived from previous projects and may still be manufactured in imperial units, but anything critical has been switched over.

The Restaurant Listed Their Hours As 11 AM To 12 PM
Everyone being confidently wrong. There’s no such thing as 24:00 in the 24 hour clock. There’s 23:59, then it ticks over to 00:00 at midnight.
I still can't convince our print company to print our invitations with 12 noon. It's much less confusing for people like this. If 12 is the meridian, it can't be am or pm, although I guess only for 1 second.
Exactly! 12 is not AM or PM; it *is* the M.
Load More Replies...12 PM is noon = around lunchtime, because if any food is really good, you might say "please, more".
He is wrong but the american 12-hour system is F**K*N STUPID. 10 AM, 11 AM, 12 PM, 1 PM, 2 PM... How does it makes sense? Some dumb English monk took the perfectly good Roman system, that had the "meridiem" as the threshold, without numbers, and decided to number it anyway but following the sequence of the previous timespan. Then, they decided to rename it "noon" after the roman Nona, that is not even mid day because it is actually 3 PM!
Best part is, there isn't even consensus among the anglosphere on what 12 AM or PM is, with some style guidelines for major US government entities, scientific institutions using different conventions, and the NPL straight out advising AGAINST using both, preferring the 24 hours format whenever an hour within noon and 1 pm must be reported...
Load More Replies...I'm not sure if I agree with the 2400 is 12 pm. That's 1200H. Midnight is 0000H. So it's open from 1100H-0000H.
