What's the dumbest thing you thought as an adult that you recently learned was wrong?

I just realized while cooking that a measuring-cup cup (as measured out as 250mL in a glass measuring cup) is the same amount(s) as one of the actual plastic baking measuring cups that go inside each other like Russian dolls lol
I thought they were different somehow (something something imperial metric yadda yadda yaddda)
Your turn to come clean Lemmings!
**EDIT: to clarify, I mean volumetrically for measuring liquids

Until he was 50 years old my father did not know how his mother could see through walls.
When he was little his mother sat in the living room while he was playing with his sister in their playroom. With a wall and a hallway between them. But every time he tried to pull his sister's hair or something their mother would shout from the living room for him to stop it. He was really angry and confused because he couldn't fathom how she could see them.
On his 50th birthday his mother revealed that she could see them perfectly fine through the reflection in a wardrobe that stood in the hallway.
mirror/reflection
Yep, that'll do it, altho its weird he didn't see her. Mirrors reflections are usually bidirectional, no? Like if I see you <-> you see me usually...
You get used to seeing something your whole life and it becomes background noise, but it wouldn't have been like that for the mom's whole life, she'd be more likely to notice that she can see him that way.
This trick also works on pets. My cat finally caught on though. And she's only 2.
Mom's are the bane of children's pesky antics!
This is a relevant metaphor for childhood trauma and relationship dynamics, wow. Thanks for that
Kid brains are something special.
I think it had a glass door so was only half reflective.
It depends on the angle. There are definitely times you can see someone/something but they can't see you.
What? Could you give an example?
The reflection is only bidirectional if you can see the other person's eyes.
It's like if someone is in a bathroom stall. You could see the stall is occupied by seeing their feet stick below the wall of the stall, but they cannot necessarily see any part of you since their eyes are not where their feet are.
Same principle applies to reflections, where maybe the body part that you can see is just the top of the head, and since the person isn't tall enough they can't see that you can see them.
If you can see their eyes, they can see your eyes. But it's possible you can see some of them without them being able to see you, or the other way around. Unless your eyes are the only part of you (because you're a camera), you need more information in order to know they can't see you.
Even when you can see their eyes that isn't always the case. It depends on how sharp the angle is and where you and they are relatively speaking. You can definitely see their eyes without them seeing you.
Definitely not.
Definitely yes. I'm amazed (but not surprised) by the lack of understanding of this concept.
I suggest that everyone here play around with mirrors and learn something themselves.
I'll leave you with this. Why do mirrors work to see around corners when you are trying to not be seen?
This might help explain things.
That link shows that Mario would see your eyes in the mirror. Those light rays work in both directions. If you can see Mario's eyes, Mario's eyes can see yours. This is clearly shown in that link.
People use mirrors to covertly look around corners because the mirrors they use are smaller than their head. And if the mirror is still spotted getting a bullet in the mirror is much less lethal than getting a bullet in the head. It has nothing to do with the mirror somehow being magically invisible to whoever is around the corner.
You are wildly misunderstanding the effect at play. All this says is peoples brains are inherently misinterpreting the angles
I'm not misunderstanding anything. That was the first article that popped up that I thought might give some of you something to think about.
Maybe I did overestimate the mental strength of those here. I shall not make that mistake again.
And to repeat. Yes, you can see things in a mirror or other reflective surface without them being able to see you. I'm still amazed at the fact that no one here seems to understand that. Everyone here must have gone to public school in a red state where they make sure you don't learn how to think for yourself.
You can see other people in a reflection without them being able to see you.
It is not possible to see someone else's eyes (except from the side, so it's only seeing their eyes in profile) in a reflection without them being able to see you too.
It's literally not possible via reflection, as everything is equal and opposite. If light can go from their eyes to yours, it's also possible to go the opposite direction.
This is what everyone has been saying but instead of thinking through everything clearly, you resorted to bullying.
The only way to accomplish this one-way vision is by adding something that is not reflection to the system (like a one-way window), but that's breaking the premise under which everyone else has been commenting in good faith.
Play around with mirrors and learn something.
