40 People Share Basic Facts That Are Ignored By Alarmingly High Number Of People

A 28-year-old woman refused to believe that vaccines do not cause autism, and that single stubborn thread somehow pulled in everything else, from “essential” oils to how fast a semi-truck can stop. The post was basically a magnet for the most ignored basic facts on the internet, and the comments turned into a full-on courtroom drama where nobody agreed on what “common sense” even means.

It got complicated fast, because people weren’t just sharing facts, they were calling out the daily chaos those facts prevent: phones blaring on the bus, headphones left behind, turn signals treated like optional decorations, and the left lane turned into a hangout spot. Then you had the heavier stuff too, like homelessness not being a simple moral failure, and the harsh reality that coming back from it is way harder than people assume.

By the time someone added the classic “cough medicine is out of stock because of a factory in Ukraine” guess, you could feel the whole comment section bracing for impact, one ignored fact at a time.

21. Medications

That your local pharmacy doesn't have any control over the actual production of your medications.Why is cough medicine out of stock? I don't know. Maybe a factory in Ukraine blew up and they are our main supplier. Maybe Jeff pressed the wrong button and contaminated all the medications on the production line. I DON'T KNOW.And yes, I am well aware that a pandemic is currently occurring. Thanks for the reminder.I hate people.FilthySingularTrick

22. "Shopping carts don't belong in parking stalls."

23. I don't know if this is considered basic knowledge, but it's really good to know:

If your car gets stuck in snow, take out the floor mats and stick them under your tires as best you can, in the direction you want to go (so the tires can drive on them). This helps give you some traction. You can reuse this technique as needed; just park, get out, and move the floor mats back to right in front/behind your tires.It irks me when I watch TV shows where the characters get stuck and can't get out of the snow when they clearly have floor mats in their car. It has come to my attention over the past couple of years that a lot of people don't know this, so now I try to bring it up every time it remotely comes up in a conversation.Also, keep emergency supplies in your vehicle: jumper cables, a flashlight and batteries (keep them stored separately because of corrosion), food/water, gloves, winter boots if applicable where you are, etc. Also, look up the underwater car episode of Mythbusters; it's just good to know :)EDIT: As u/ruetheblue says below, if the snow is covering the tailpipe, TURN THE CAR OFF.

Cover it with the pot or pan lid and turn off the heat.Edit: People in the replies have also added that baking soda and salt can work to smother the fire. Additionally, a grease fire-safe extinguisher is a good thing to have in your kitchen.MakennaTalia

40. "Just the basics of using a computer, especially nowadays when most things are done digitally."

It’s just mind-boggling when a co-worker's Wi-Fi does not work, or a program freezes and they just don’t know what to do. Then, when I reset the router or restart the computer, they proceed to call me a wizard. Like, dude, what the heck?blgbra6

That’s when the “vaccines do not cause autism” comment immediately got tangled up with the mom who still believes it, even after everything else in the thread got real.

Then the bus scene hit, with people arguing about whether forgetting headphones means you’re inviting the entire crowd to hear TikTok at full volume.

After that, the traffic rules piled on, because someone had to explain turn signals, left lane behavior, and why biking with traffic is not a vibe, it’s safety.

Finally, the pharmacy section turned into a blame spiral when someone guessed cough medicine shortages were due to a far-off factory explosion, and nobody could agree what was actually true.

Knowledge is a term that refers to a real belief that may be distinguished from an opinion or educated guess by the use of evidence. Here, we see people who might know what they ought to do, but they fail to act.

The scariest part is how confidently people keep repeating the same wrong basics, like they’re family lore.
