    How to explain to Americans: If You remove 3 bullets out of an Gen 4 Glock 26 9mm 12-Round magazine, that’s 1/4. If you remove 4 bullets, that’s 1/3. The police can shoot one more unarmed black man with 1/3 of the magazine than 1/4.

        No, the poor Americans will be confused by the inversion.

        First removing 1/3 (4 rounds) from a 12 round magazine leaving 2/3 (8 rounds) left … then switching to talking about how a 1/3 full magazine with its 4 rounds has more rounds left than the 1/4 mag with 3 rounds.

        They won’t be able to catch on, and are likely to respond with something along the lines of “But the one you took 1/3 out of has just 8 rounds left, and the 1/4 one has 9 rounds left, which is more. The 1/4 one is more.”

          Since you didn’t get it, you can cut a cake visually and have it make sense where you can’t with burgers.

          Cut a cake into 4 pieces, another cake into 3 pieces, the cake with 4 pieces, each piece is a 1/4 piece, the other cake for 3 and 1/3, which is bigger?

          It’s easy so I’m confused why you didn’t get it.

              Yeah, when I talk as I normally do to people they don’t understand me so I need to get on their level most of the time and that pisses me off because it really doesn’t take much effort to have a decent vocabulary and a basic understanding of how the world works so I end up being bitter, misanthropic and sarcastic nearly all of the time.

              80% of my life I feel like wherever I go I’m talking to stubborn, self-important children who think anything they don’t understand cannot exist.

              And it’s been that way for more than 4 decades now, so yeah, I talk down to people a lot because most of the time that’s all you understand.

                You have to respect that people are smart in different ways. The human mind has to spend its time doing something.

                Likely the people you meet have completely tangential interests to yours and so you don’t notice their intelligence, but there will always be a topic that someone else is expert in to which you are a novice in.

                The key is to bridge those small interest overlaps by finding a common vocabulary that you can use as a basis for examples. If you truly understand a topic, you should be able to create digestible examples for it.

                Refusing to compromise on this is more a sign of immaturity and insecurity, than a consolidation of your intellect.

                  Yes, Drumpf is an idiot for everything except manipulating people. Should I ‘respect’ his ability to literally get away consequence free with *Gestures wildly at EVERYTHING*

                  so you don’t notice their intelligence,

                  No, most people are idiots through and through, some people have self-improving interests and hobbies that gives them greater breadth of though, but I’d argue that’s less than 20% of the population.

                  Most people have a calcified worldview built from things their families and friends tell them with very little self-examination that they are STUBBORNLY resistant to shedding, and will ghost family instead of addressing their internal conflicts.

                  Look I get you have a positive view of humanity and at one point so did I but I cannot stress to you the importance of the fact that 60-70% of the population are basically just children that refuse to leave the Concrete Operational mode.

      My high school was great, if you were doing poorly in a class then next year they’d put you in an easier class to bring up your average grade (And if that didn’t work, then they’d just ignore you).

      Chuckle? Hell I know full grown adults in their fifties who wear their mathematical ignorance as a badge of pride!

      It’s like they’re clinging to their youth so desperately, that they continue on with the high school trope that only nerds who are undeserving of social interaction know math.

      Meanwhile, they also tend to continuously moan online how broke they are - inevitably from decades of poor financial decisions that landed them under a mountain of usurious debt with double digit compounding interest.

      They also like to get grammatically pedantic on the regular to show off their superior language skills - usually when they’ve got nothing of value to contribute to the conversation or they know they’ve been bested, so better point out those autocorrect errors.

      I know there is a syntactically correct way that everyone knows and accepts, but it does depend on what the expression is.

          When I was in elementary school I knew how to use the signs but not how to read them. So I’d always read it as greater than and flip it. So 3 < 5 I would read out loud as “5 is greater than 3”. My teacher quickly corrected me though. So it was only for like a week or so.

          Exactly, both of those statements convey the same information but are encoded in different ways.

          To a foreigner, seeing the > < brackets may be more contextual than it is symbolic.

              Yes, but if you have 5 > 3, you can read the “>” in two different ways:

              1. 5 is greater than 3 (reading left to right)
              2. 3 is less than 5 (reading right to left)

              So which one is the correct way to spell out “>”? I also was confused about that for some time, since I was taught that the pointy end always points to the smaller number which is intuitive and can very easily be remembered, but I still had to memorize which symbol is pronounced as “less than” and which is pronounced as “greater than” until I realized that at least in every language I speak it’s always read from left to right.

              It still takes a bit of a second for me once in a while these days to remember the correct name for the signs when I see them.

                The way my mind works is I find it faster to reconstruct the meaning every time rather than attempt to memorize which one is said which way.

                Example: 3<5

                My mind:

                1. 3 is the small number / 5 is the large number.

                2. How do I say that in a sentence?

                3. Three is less than five.

                I do the math, not remember the definition.

                  If english is your first and main language, then there is no confusion mapping “less than” → <, and “greater than” → >.

                  If english is not your first and main language, then you might hesitate or ask for clarification on the symbols, or guess from the context.

                We were always told < is less than. The symbol looks like an L for Less. If the L is facing the wrong way > it’s greater than.

        for some reason people love to revisit things like this and find post hoc justifications for dumb fucks to make them look smarter. it happens a lot with elon and TFG too.

        but the one timeless example that pisses me off the most is W’s “fool me once” flub. every time it’s mentioned, so many people come to his defense, adamant that it was on purpose! supposedly he didn’t want to have a clip of him saying “shame on me” on camera to be used against him in political ads and whatnot. not like we have tons of evidence that he was a fuckwit before that, and never mind that there’s absolutely no evidence for this to be so propagated like it’s a fact…

        but this is such bs on so many levels that I’m getting angry even right now thinking about it. wow! such marvelous political instincts… he sure didn’t end up giving a much worse soudbite that made him look like an absolute buffoon now, did he? what a savant!

        no, people can be stupid. but also the american public in general? come on… there’s areas in which you can try to save your national pride, math ain’t one of them.

        Yeah, I would think so. No other restaurant had problems selling 1/3lb burgers. Braums and Carls Jr sling them by the truckload. Almost all the small family restaurants here sell their burgers by 1/3lb 2/3lb sizes. And I don’t exactly live in an area known for it’s high intelligence. So I’m calling shenanigans.

          Every record that I can find says Carls Jr debut their 1/3 lb thickburger in 2002 and Braum’s was founded in the 1980s.

          So they were absolutely NOT contemporaries of A&W when they were marketing their 1/3 lb burgers.

          I’m not really sure what people like you get from coming here and lying on the internet, but I am so fuckdamn tired of it.

            Edit: the claim in the OP is “1/3lb burger failed in america” nothing to do with the 80’s. Lots of places still sell 1/3lb burgers 40 years later.

              Video games also failed in America. Some even thought it would never come back into prominence, and I don’t recall if it’s related but the writer of the Wticher books sold rights for the game in hard cash and not percentage of profit because he thought they’d never make money as a video game.

              Failed and such doesn’t mean forever. Things can change or changes in advertising/quality control can restore dead markets. Now maybe this means as you said it wasn’t American stupidity, but were also talking Americans who supported segregation at one time and by majority now do not. As different people grow up or even if people heard about this and learned to be less dumb, the conditions in which the original failure could have changed, making the statement true at the time.

              the claim in the OP is "1/3lb burger failed in america

              It did, in the 80s, when A&W tried to sell them. I live a 30m drive from the original A&W, they have newspapers up from that time with the people bitching about it. It’s a popular “fun fact” style story and has been since it happened

              The practice wasnt successful until the early 2000s, a little after it had become a fun fact that became more and more widely known. I think I even remember seeing an ad for Carl’s Jr that played on the fact that A&W had failed where they were succeeding and made some joke about dumb older generations or whatever to appeal to the youth

              Then they aren’t contemporaries of the time when A&W debut their 1/3 burger NOW ARE THEY?!

              I’m not really sure what you and the above asshat’s motivation is, do you think that somehow your intellectual dishonesty will make people think Americans are less stupid on average?

              Frankly I don’t even care and I am so fuckdamn tired of your kind.

            Nah, if you look in any American kitchen, you’ll find 1/3 cup and 1/4 cup measuring cups. They may not use them, but everyone has them, and it’s painfully obvious that the 1/4 nests inside the 1/3, therefore the 1/3 is bigger. If you want to make mac 'n cheese, you use the 1/4 for the milk, which means you’ll take it out of the 1/3 cup.

              Americans are so bad at measurements that graduation marks don’t work for them.

              They need an individual container for each common measurement.

              It’s absurd.

                Lol.

                But yes, we do have graduation marks like this one, which would also clearly label the 1/4 cup and 1/3 cup parts. Whichever one you have, it’s pretty intuitive that 1/3 > 1/4. I prefer the separate ones since they take up less space so they can go in a drawer instead of the cupboard (and I have 2-3 of each size), but to each their own.

      My teacher put a kid with dwarfism and tall kid side by side in front of the black board and drew a line between the tops of their heads, and then another still downwards but in the opposite horizontal direction. Thus the pointy end always faces the smaller thing, while the open end always faces the larger thing. Doesn’t work so well in english, though since it kind of implies people with dwarfism are “less than” people without the condition. In the language it was taught the verbs used for < and > are also used when comparing heights.

        That was another point of frustration. People would think if they asked for a half pound and the scale reads .6 they get a deal, but in reality it’s just printing a label that says my pounds and they gotta pay accordingly. Some customers would accuse you of ripping them off if they asked for a specific amount and got that amount exactly.

            Beats me. It’s not like we were taking money at the deli counter either. Also the labels say how much weight there is, price per pound, and the total price. Just like meat from the meat department would. But I guess because they’re asking for it in person they think it works differently.

    Well, the 1/3 also had to compete with the double-quarter (aka, half pound, but two patties), which is bigger and feels significantly more substantial as well.

    It doesn’t help that any place I saw selling them (let’s be real here, this is about McD’s) was offering an expensive and fancy 1/3rd burger (deluxe bacon, southwest ranch style, Asian sensation with real gold flake, etc) against the old reliable (cheap) quarter-pounder. Perceived value is everything.

    Also, we’re bad at math, lol

          I keep seeing people talking as if they didn’t exist anymore but they still have about 600 restaurants in the US and 400 elsewhere (not counting the Canadian version which is independent and doing very well as far as I know and actually has more locations than the US chain)

                First restaurant founded in 1923. 1972-1923 = 49 years. 2024-1972 = 52 years.

    It doesn’t take a ton of mental capacity, but even though I have a good education in math, I still find myself doing the heuristics of assuming that larger digits means larger number. Using fractions for comparing sizes can flip these heuristics. And I think a lot of people are like me, and also that they won’t spend a lot of time reading each item on the menu.

    Where I’m from, burger sizes are just given in amount of grams, which makes it a lot easier to compare.

        Fractions are easier to do calculations in your head or on paper than trying to do the same stuff in decimals. E.g. half of 1/2 is 1/4, half of 1/4 is 1/8, half of 1/8 is 1/16, half of 1/16 is 1/32 etc. In decimals this would be 0.5 -> 0.25 -> 0.125 -> 0.0625 -> 0.03125. When building stuff, I find it useful to be able to do that kind of stuff in my head easily.

          The problem occurs when you have a 1/4 pound burger for $1 and a 1/3 pound burger for $1.25. Is it worth it?

          If only using fractions in powers of 2 1/2, I understand that it’s simpler. A carpenter is happy to meassure 3/16s of an inch, since the tools have notches or marks for that. But when you include other fractions, it becomes messy.

          How much more is 1/3 than 1/4? Instead of handling digits, you have to find the lowest common denominator to perform the subtraction. I.e. 1/3 - 1/4 = 4/12 - 3/12 = 1/12.

          And at this point, I believe the relationship to the units are lost. Do you have any direct sense to what 1/12 of a pound is?

          The 1/3 pound burger is (1/3)/(1/4) times the size of the 1/4 pound burger. So the burger is worth it if $1*(1/3)/(1/4) is greater than $1.25. We arrive at $4/3 which we want to compare to $1.25. Now, since we are relating units which use fractions to units where fractions are unusual, we have another problem. (Yes, we can easily see tha 4/3 = 1.333…, but we wanted to use fractions, right?). So to compare the numbers, we can see that 1.25 = 125/100, which we can simplify to 5/4. So in the end we are left with the simple problem of finding which is bigger between 4/3 or 5/4.

          To summarize, I agree that fractions are nice when you have them in a vacuum and don’t have to relate them to numbers of other units.

              I get what you mean, but its adding a useless complexity layer.

              If the thing always is smaller than, for example, a kilogram, just use the next measurement unit, a gram. 100g, 200g, 500g, etc.

              It’s true the other way around, if the thing is always bigger than, for example, a kilogram, use it as is. 1kg, 1.5kg, 4kg, 6.2kg.

              For ease of comparison, always use the most significant unit.

      Interesting.

      But we use fractions a ton here in the US. For example, you can buy milk in a half gallon or a gallon. When you measure, you use 1/4 cup or 1/2 cup. In metric, you rarely use fractions and instead just change the unit (e.g. 250ml or 1L).

      Since it’s so common here, it’s honestly nuts to me that anyone here would be confused at whether 1/4 lb or 1/3 lb is bigger, because we use fractions so often here. If you’ve ever cooked anything in your life (incl. macaroni and cheese from a box), you’ve dealt with fractions in real life. I probably do more fraction math than decimal math, especially since I buy everything with my credit card, so when I see a decimal, I round it to the nearest convenient fraction (e.g. I bought 4.5lbs of meat recently for a dinner party, and I communicated that as 4 1/2 lbs). If you ask me how many ounces are in a 1/4 cup, I’d have to stop and think. But if you ask me how many 1/4 cups are in a cup, I’d have the answer for you on the spot.

      So I could see this happening in areas where fractions aren’t common, but in the US, it’s something everyone deals with, pretty much daily. Oh, btw, we have one of these at my local dump:

        It’s indeed a form of mental laziness because the mind is designed to approach some concepts with a non-perfect optimization. That’s heuristics. Yes, I can very easily see which number is the largest if I put my mind at it. But scanning over a fast food chain-sized menu, seeing numbers for 2, 4, 8, 12 piece nuggets, prices on different items and a 1/3 pound burger next to a 1/4 pound burger, I could easily see my mind skip the math and mess up the size comparrison.

              Like the article says in the first sentence, heuristics “is any approach to problem solving that employs a pragmatic method”. Looking at fractions and assuming that the big number is larger is not a pragmatic method, it’s a completely smoothbrain approach. I can’t even comprehend how you think that’s a good approach to fractions. It’s just flummoxing.

                I think we just disagree on the level something has to be to be considered “pragmatic”. Almost all numbers we deal with in a daily basis are not fractions, so it’s very natural to develop a shortcut to quickly look at digits to compare numbers. That is a practical approach.

                Now, if you don’t get too stuck on the word “pragmatic” but actually finish the sentence, you might find it to be more applicable.

                Or maybe even look at the wikipedia page for heuristics from a psychological perspective:

                  Yes, I disagree that looking at a fraction and thinking “bigger number = larger number” is heuristic. It’s just really extremely dumb and I can’t even.

                  That’s it. There’s no argument, although you seem to think there is.

                  I believe that’s the jist of it. Heuristic is a way to get a roughly correct answer to a specific problem. If it doesn’t provide a response that stays in the same ballpark of the real solution to the problem it’s not heuristic, it’s just a wrong train of thought.

    The third burger failed because it was a stupid amount when it came out, iirc it was more expensive than the quarter lber and like a dollar less than a double quarter lber.

      Why the fuck would you bring ounces into it? We were having a perfectly fine conversation here and now you’ve brought imperial unit conversion into the mix.

      What’s the ounce to pound thing again? 12? 16? 20, or 32 or something? Who am I kidding? I don’t give a shit.

      If you’re not using metric at least have the decency to stick to pounds, kilopounds, millipounds, micropounds, or whatever the fuck you want to name your orders of 1,000. Just don’t ever come here fucking about with short tons and long tons or I’ll strap you to a board, drop you in a tub, and drown you in a metric ton of sewage.

          It’s probably just a british person complaining about units as they can’t make up their mind what to use. Ounces is perfectly valid in the context of pounds…

            A pound is roughly half a kg, we can work with that. But nobody outside the imperial using countries knows what an ounce is, and we don’t regularly use any unit close to it.

                Ok. Canada finished converting in 1985, there’s bound to still be a lot of people who grew up with imperial. “Current or former imperial using countries” then.

                  You clearly don’t live in Canada. Imperial units are very common for measurements. You ask nearly anyone, old or young, their height or weight, you’re getting an answer in feet/inches or pounds respectively.

                  Tons of baking is done using cups, tsp, tbsp etc.

                  Golfers use yards.

                  I’m sure there are more examples I am forgetting, but you get the idea. It’s not just people who grew up before 1985. It’s everyone.

              Pretty much everyone uses troy ounces for things like gold.

              But if you’re in the US, you also need to be more specific, since we also have fluid ounces.
