questionswhat is something you were just plain wrong about?


Hot water does freeze faster, I thought. The more dramatic temperature change and other physics stuff I only half understand.

But my answer is nothing. I'm never wrong :)



Maybe our experiment wasn't controlled well enough or the trays got switched.
I will definitely be revisiting.


TL;DNR on @carl669's post: Under certain circumstances hot water can freeze faster than cool water. See: Mpemba effect

For some reason I remember reading at a young age that Pepsi had more caffiene than Mountain Dew. Turns out Mountain Dew has a lot more. Not sure why I thought that it didn't.


I didn't believe the Monty Hall problem.

If you were given the opportunity to win a car that is behind one of 3 doors but the other two doors have a goat behind them. You pick door number #1. The host then opens door #2 to show you that it has a goat and gives you the option to keep your choice of door #1 or switch to door #3. It was mentioned that you should switch because it does make a difference statistically. I didn't believe it and was very vocal against it.

So then I did a computer simulation of this and it's true. It really does make a difference if you switch. The chances are in your favor to select the other door that you didn't initially pick.


Back to the OP: What is something you were just plain wrong about?


There are two types of people in the world: people who love opera and people who've never been to an opera. I used to be the second type.


I thought I was wrong once, but I was mistaken.


The pronunciation of the word "renovate." Before I saw it in writing (or, at least, before I PAID ATTENTION to the word in writing), I said "re-innovate." I seriously thought that this was the word.

Having said that, I'm sure I've been wrong on any number of occasions. I have managed to raise two kids who still live at home in their 20's, so that is proof of something I've done wrong, at least. On the other hand, neither is in jail, so there's that.


The apocalypse. And now I've got this darn Thunderdome in my back yard.


re: hot water freezing; Can under certain conditions is far far away from does
just saying.
Since I offer vague and/or "all probable outcomes" as replies to things, I am rarely incorrect.

I just learned yesterday that "renumerate " isn't really a word - the word I wanted was "remunerate".


@cengland0: I was the same way in one of my informatics courses. The short version explination:

When you initially make your choice your probability of making the correct choice is 0.33 (1 in 3). And (this is the hard part to wrap your head around): that probability does not change moving forward.

So, then Monte reveals one of the wrong choices. The probability of the door you didn't choose having the car is now 0.5. But the probability of you being correct initially remains at 0.33

Of course, IRL it isn't so easy. This assumes that Monty will always play the same game regardless if you were right or wrong initially. If you know that the contestant knows this is the preferred strategy, you would only offer it if he guessed right correctly, knowing he would jump to the wrong door, and not offer if he was wrong initially.


@wilfbrim: Actually, the way it works is that the door you first picked has a 1/3rd chance of having the car.

The other two doors combined have a 2/3rd chance of having the car.

You open one of the doors that you didn't pick causing the remaining door to have the full 2/3rd chance of having the car.

And you are right about the consistency. For example, if you picked door #1 and it contained a goat, the host might immediately open door #1 and say, oops, you didn't win the car. But, if they always reveal a door that you did not open and let you decide to keep the door you originally picked or change to the remaining unopened door, the statistics are in your favor if you switch doors.

If you do not switch doors, you will win 33.3% of the time. If you do switch doors, you will win 66.6% of the time.


@cengland0: I saw them test the Monty Hall problem on Mythbusters. Very interesting.

You can not put metal in a microwave. Turns out you can, you just need to be careful on the shape.


We deleted a JetBlue deal a few days ago...

...just sayin'.


@caffeine_dude: I love he Mythbusters and wish I still had a satellite dish so I could watch them. Unfortunately I'm too poor so I only have an outdoor antenna.

Here's the non-Mythbuster's explanation:


@machgogogo: Copy that on the ex-wife.

It turns out that the wise man marries his second wife first!


Lots of things. Sometimes on purpose. Even though I know you are not supposed to, I pronounce the "l" in salmon. Saying "sammin" sounds childish to me, like saying "basketti" instead of spaghetti. I used to argue that if you were in a plane traveling faster than the speed of sound you couldn't talk to the person in the seat in front of you, just to watch my science-inclined friends' eyes bug out. I like to speculate that we all see different colors, but we have all been taught to call that color in the sky blue so that's the name we assign to whatever different thing we are all seeing. My grandmother touted the hot water freezing faster thing and I treated it like I treat a lot of stuff (including religion), I allowed for the possibility without believing it myself. I am wrong often enough and am sufficiently comfortable with it that I don't recall the times I have been wrong.


oh man, LazyZombie, I was flat out wrong about that.


@moondrake: As a child I always believed the color thing, still don't know if I'm wrong about it.


@moondrake: I've been trying to convince DH of the color thing for years. It's not that he doesn't believe me, it's that he doesn't seem to comprehend what I'm saying. I also believe that the same thing applies to taste and smell. What I call "sweet" might not taste the same to you, but since you've been taught that candy is sweet, you call it sweet regardless of how you experience that taste. I took an undergrad course in sensation and perception many years ago. We hashed over my theory in class back then, but, of course, there was no resolution.

I'm wrong on a regular basis. Just ask anyone who lives with me, especially if I married or gave birth to them. (sigh)


@blgauthier: wow, I think I've been saying that wrong too! EDIT - oops, I mean @secretagentman02

For me, when I was little, the pronunciation of the word "naked". At some point in my very early life, either me or my brother mispronounced it as "bacon." And before bath time (we were probably 2 and 4 yrs old) we would run around inside the house yelling "running bacon! running bacon!" After I realized that we meant "naked", I started yelling that, but it just wasn't the same.


Hmm, just now I learned from a TV show that the word "forte", as in "TV sports are not my forte" is pronounced fort, not fortay. So I have been saying it wrong all my life.


The lyrics to "Margaritaville". In my youth, I decided warm front was the two syllable w word in the line: "Some people claim that there's a woman to blame." Weather seemed more likely to be trouble at the time.


@moondrake: You weren't wrong - according to " Both the one- and two-syllable pronunciations of forte are now considered standard ".

(Is it just me, or is Blue Bloods getting more and more like a daytime soap? I'm surprised it hasn't been cancelled yet, and I don't think I'll miss it when it eventually goes).


@ripwave: But it's now considered standard because so many people got it wrong that the word just surrendered. That's how "alright" got into the dictionary. There's an interesting tension between proper English and English as a living language.

Yeah, Blue Bloods has lost a lot of it's drive, but it was never one of my favorites. Usually it's my favorites that get canceled, so I expect it will keep chugging away. Tom Selleck is still a force to be reckoned with, if the show is canceled I hope we see him again in a meaty role.
