People who argue that cold water will freeze faster than hot water when everybody knows that hot water freezes faster, right?

Hot water freezes slower but it has less dissolved air therefore it has more mass and therefore more heat capacity.

It's not a "wager" for anyone playing. It's wishing on a star.

Go find a fountain full of pennies. Throw one in and make a wish for a million dollars. Is that a wager? No. But it's exactly the same as playing the lottery.

Look... You don't get it. I get that you don't get it. Just leave it at that.
...The fountain isn't offering anything in return though, nor is any other person or entity. Any idea of getting a return on the coin is purely imaginary.


Roulette: You bet that the ball will land in a certain location. The ball randomly lands in a certain place, and you either win money if it lands in your favor, or you get nothing if it does not.

Lottery: You bet that the randomly-generated numbers will be in your favor. You either win money if the numbers are in your favor, or you get nothing.


Both are just forms of gambling.

The concept of selling used stuff on CL.
I see ads all the time when people would say, " I paid $xxxx for it".
I don't give 2 shits what you paid for an item.
Just because you overpaid for an item, does that mean you can sell it for more ???
If an item is worth ~$100 but you paid $400 for it back then, its still worth $100.

The best is people selling their old 2000 era computers. "I paid $3,500, only asking $900". That pentium 3 computer is not even worth $900! $100.. .MAYBE? A Raspberry pi is more powerful, and cheaper.

A late p3 might be worth forty, maybe, but only because it runs. You can get first generation C2D systems from university surplus sales for $50.

To generalize, most people are just bad at statistics, probability, money and driving.

Statistics:
-10x MORE TOXIC compared than something else is still as non-toxic when both are magnitudes below the safety threshold.

Probability:
-1 : 10 million of winning lottery = I'm going to win this week! (Considering the average human won't even live long enough to see 5000 weeks)
-1 : near infinity risk of death - OMG WE ARE GOING TO DIE FROM NUCLEAR RADIATION FROM JAPAN

Money:
-I can spend money on luxury items but I don't want a health insurance plan, when even though the financial consequences of not having it when diseases actually strike can be well over 100x of the pittance of premiums I that will save and disqualify me from getting said insurance.

Driving:
-I can tailgate because.
-I like to pay a lot more for car maintenance because my braking skills are shit.
-Bastard made me rear-end his car because he is an asshole who braked too hard, not because I'm too dumb to keep a safe following distance and pay attention in front.

This is crazy talk. It sounds like you got rear-ended or something.

I was selling a metal detector recently on craiglist. New it is $600.00. It was 1/5 years old and in excellent condition.

I received an offer for $150. I received many offers for $300.00..

yeah.. no.

Ended up selling it for $425. Everyone wants to lowball you on stuff. I agree, it doesn't matter what I paid for the item, but when you are offering way below fair market value (as shown by ended and purchased ebay auctions and other sites selling the same detector), I just shake my head.

On the opposite end of the spectrum, used S939 Athlon 64 X2s were selling over $200+ on Ebay during a time where one can get themselves a brand new C2D + mobo + DDR2 combo at stock speeds that destroyed anything from S939, let alone overclocked with the same money. That makes absolutely no sense because if you can install a CPU you surely have the technical know-how to install a mobo and RAM too.

This is crazy talk. It sounds like you got rear-ended or something.

Nah. I simply can't believe how anybody can remotely suggest the safety of their own car is the sole responsibility of anybody but themselves. These dangerous retards need to be banned on the road.

Oh, another road stupidity: Just because you can ride a high capacity motorbike at high speeds doesn't mean you are in any form of an expert with a bike. Any idiot can do that at high speeds, doing it safely while equipped with very slow skills is one whole ballgame altogether. If you can't even make a proper U-turn do everyone a favor and don't ride on the real road, thank you very much.

I think listing the original price has some utility for a buyer. I might not know much about metal detectors, but it wouldn't take long to find out how much I would have to spend to get a new one with the functionality I wanted. Finding listings that mention an original price that is in that range is one way to filter out the things that I don't want. Of course then I would move on to checking if the seller is being honest with their price, but even that would allow me to further narrow my range of choices by filtering out dishonest sellers. I encourage sellers to give me as much info as possible, accurate or not. It will always help me to either decide to buy their item or help me decide to steer clear of it.

Sounds like one of those annoying people who coast the last half mile to every stop sign. Aren't you worried about getting home in time to catch the new Antiques Roadshow, grandpa?

Simple example: I walked into the kitchen at my parents' house the other day and the oven door was open, even though the oven was off. My mom leaves the oven door open so as not to waste the residual heat after the baking is finished (during the winter).

Few years back I was talking to my dad about insurance and how the premiums go up every year even if you never make a claim. He said "Well, the insurance company knows that if you go for a while without an accident, you're due." I argued no, that's not the case, and pointed out that if you flip a quarter and it comes up tails 9 times, it's still 50/50 odds on the tenth flip. He told me 'no', heads is more likely on the 10th flip.

I'm always amused by these seemingly straightforward scientific and mathematic concepts that seem to elude people for whatever reason.

Another one that I've heard of but never personally run into is people that don't understand how graduated income tax rates work. i.e. they believe there are certain breakpoints where earning another dollar of income will result in reduced earnings because the taxes on their entire gross income will increase.

Anyone else have examples?

Damn. That's legit.

"Haters going to hate hate hate"

From the Taylor Swift song, except Taylor was probably referencing trolling by people about trivial shit like who she's dating, how much her music sucks, her hair, etc.

Somehow, people in serious trouble have used it as a defense. For example, one was involved with an alleged conflict of interest, the other allegedly misused company funds -- both pointed to "haters going to hate" in defense of their misdeeds.

My wife surprised me recently by telling me she thought to turn the fridge up higher (1-2-3-4-5 etc.) would mean it being warmer, eg. 1 being the coldest setting. She really did not know what direction to turn the knob...

*

And..of course...MOST economic/political/ecological concepts....this is why politicians use emotions to catch voters. (Because they KNOW that most people are dumb). Emotions don't require thinking.

*

The fact that people line-up in large crowds when there is a jackpot in a lottery. This is dumb for many reasons.
A) a jackpot means no-one won in a long time, so it's basically proof for the idiocy of a lottery
B) a jackpot doesn't increase your odds of winning
C) whether you win, say $5M or $50M or $500M is from a certain P.oV. irrelevant, saying that the notion of winning, say, $5M in a normal game is not less attractive than the notion to win $500M because there is a Jackpot. YET, many more people play when there is a jackpot, people who otherwise don't even play the lottery. LOGIC?????

*

The fact that illegal immigration is a tiny joke compared to the damage that outsourcing and 3rd world manufacturing does. Yet, in capitalism, outsourcing is entirely fine....a company outsourcing 1000s of jobs to India is ok....while around the corner there are standing protesters who want Jose and Ramirez go back to Tijuana "because they steal our jobs" etc..

Planet of retards.

Many people find that counter-intuitive. I don't know the numbers, but I'd guess it's around half

Reading instructions, no matter how simple they are. Part of my job includes writing technical documentation, and no matter how much I dumb it down, people just don't want to read. It's amazing. They shoot themselves in the foot over & over again simply because they want to dive right in. I've had customers blow through tens of thousands of dollars of equipment simply because they don't read simply things like the color-coded wiring diagram. Constantly blows my mind.

Yeah. Manufacturers know this so they put markings like "Colder" or a snowflake that tells people which direction is colder.
