Some people will believe anything, especially if they stand to gain something by it. This is what gives conmen, hucksters, snake oil salesmen, and Nigerian “princes” an endless supply of hapless victims.

Someone asked the internet, “What’s a lie people still believe no matter how often it’s debunked?” and a community of netizens were only too happy to weigh in with patently false facts some folks still stubbornly cling to. Here’s a collection of the most ridiculous.

Medical clinic entrance at night with illuminated red sign, highlighting common debunked lies people believe about healthcare. People believe all day long that abortion bans, reducing birth control and s*x education will lower abortion rates, rather than looking at the policies of countries who ACTUALLY HAVE low abortion rates and doing what they do. (Which is not banning abortion, making birth control EASIER to access and by giving comprehensive s*x education young).

Not being theist and allowing sexual education and birth control and overall an non-shamimg of s*x makes a better life and less shameful life and etc etc.

    We live in the age of search engines, fact-checkers, and science at our fingertips. So, why do some people still believe that lightning never strikes the same place twice or that vaccines cause autism? The answer: human brains are weird. And messy. And deeply committed to clinging to whatever feels easiest, even if it’s wrong.

    Repeat something often enough, and it starts to feel true. That’s not magic, it’s psychology. The “illusory truth effect” means the more we hear a lie, the more our brains go, “Well, that sounds right.” It’s why urban legends live forever and your uncle still insists shaving makes hair grow back thicker.

    Not just abducted. If a person is vulnerable they should be reported far sooner than 24 hours. There is no standard length of time to wait until calling for help. So much depends on the person, their health, their situation, the weather, etc. There's a vast difference between a 3 year old who has managed to open the front door and has wandered off, and a 21 year old student who was last seen two weeks ago. If you are concerned, phone the non-emergency police number and ask for advice.

    We’re all guilty of loving information that agrees with us. Confirmation bias means we seek out stuff that matches what we already believe and ignore what doesn’t. So even if the truth is doing jumping jacks in front of someone, they’ll still believe that gluten is evil because their favorite podcast said so.

    When someone’s beliefs get challenged, it actually causes discomfort in the brain. That pain? It’s called cognitive dissonance. And instead of facing it, many people double down on the lie. It’s easier to scream “FAKE NEWS” than admit your favorite childhood fact about goldfish memory was always total nonsense.

    This idea comes from the 'average life expectancy'. That's true, but this is because so many babies and little ones died in the first five years old life. Many women died in pregnancy/childbirth, and young men died from war, hazardous work, and doing stupid things. If you survived these things, you'd live a decent amount of time.

    Here’s the secret sauce: lies often come wrapped in juicy emotions. Fear, outrage, nostalgia, take your pick. These feelings make the lie memorable and hard to forget. Cold facts are great, but they rarely spark joy. A juicy conspiracy theory, on the other hand? It comes with drama, excitement, and a built-in villain.

    This study was done on random wolves thrown in captivity. It was the equivalent of studying prison behavior and thinking you know how humans behave. In the wild, packs are family units. Mom and Dad are the 'alphas' and the rest are their kids. So the guy you see at the amusement park, with the waist pack full of snacks making sure all his kids are having fun and are fed and hydrated? That is the trueest alpha male you will ever meet.

    Admitting you’re wrong feels like stepping barefoot on a Lego block. So people protect their self-image by defending old beliefs, even when they’ve been proven false. It’s not about being stubborn (well, not just that), it’s about pride. Saying “I was wrong” is tough, especially when the lie became part of your identity.

    Some falsehoods are more entertaining than the truth. Aliens built the pyramids? Intriguing! Birds aren’t real? Hilarious! Reality is often boring, and our brains are wired for storytelling. So even after a myth is debunked, people keep repeating it because it makes life a little spicier.

No, I think it was because they want to believe the schools will accommodate this and thus are a threat....to the children....yeah....

    In the end, lies don’t win because they’re convincing; they win because they’re easy, emotional, and ego-friendly. Truth requires effort. Lies let us stay cozy in our comfort zones. So next time someone swears chewing gum stays in your stomach for seven years, remember: it’s not ignorance, it’s just psychology doing its messy thing.

    I've heard so many people say that they have made less money after getting a raise. Those people are either lying to try to prove a (dumb) point or they don't understand how numbers work.

    EDIT: Yes, there is the Medicare Part D donut hole, but that's not what these people are talking about. This is straight up, "my boss tried to give me a 5% raise but I turned it down because it would put me in a higher tax bracket.".

    Pregnant woman in casual clothes sitting on a couch holding her belly, illustrating common lies proven false over time. That when women spend enough time together, their cycles sync up. It’s simply not true. Everyone’s cycles are different, so if you spend enough time with someone, eventually they’ll align for a bit. It’s like when you’ve got your indicator/blinker on and you’re comparing it to another blinker (just me?) - they’re out of sync until a couple of blinks, when they momentarily align (which is satisfying as f**k, or maybe I just need to get a life).
