Similar things happen surprisingly often in companies. Many intense arguments can be diffused by first being specific about what we agree upon.

Just to add to this, one strategy from the rationalist community that I rarely see practiced is to 'taboo' certain words. For example if two engineers are arguing about a solution not being scalable, taboo the word scalable. They both re-explain their POV without using the word scalable at all. It often works like magic and they quickly reach a shared understanding.


A great word to taboo in hardware tech is "performance".

I once witnessed a very heated argument among a group of programmers discussing some code on a microcontroller. Half of them thought the performance was abysmal. The other half thought the performance was great. To everybody it was obvious to see what the performance was, why were the other half being so bone-headed about it?

Turned out the first group were trained mechanical engineers, the second were trained software engineers. For the first group, "performance" meant how closely the motion of the device attached to the microcontroller tracked the optimal path. I.e. the performance of the function approximation that the microcontroller code was doing. To the second group, it meant how fast the code ran. This was completely irrelevant to the first group, since as long as it managed to run 1000 times per second (which it easily did), nobody cared how many nanoseconds there were to spare each cycle. Why are you even talking about that? The performance is shit, we need to improve it and who cares if it takes a few more CPU cycles.


Applause! I hate the word "performance" and its evil spawn, "performant".

Do you mean speed? Efficiency? Accuracy? Say what you mean.


This is my excuse for why I have no idea what "performance optimization" entails or means. Now to convince interviewers..


In a context of an interview it means how performance of an algorithm scales with respect to the input length. This is measured in Big O notation. Understanding that is seldom very helpful on the job, but it's very important for interviews, so make sure you learn it.


That's not specific enough. Memory usage, elapsed time, and energy usage are all functions of the input size, and each is a different optimization problem. Instead of talking about performance optimization, you should be talking about memory optimization or speed optimization.


Hahaha I appreciate the candor. Frankfurt's On Bullshit has never been more appropriate than at this time in my life and in history.


I wish it was a common practice to ban certain words from difficult conversations. But whenever I suggest it people just talk past me as though I've said some weird thing.

There's facts and opinions, but also definitions, and too often disagreements boil down to a different definition of a single word. Ban that word and say what you mean and the disagreement may suddenly be gone.

Edit: I wrote this before reading the second paragraph. :) I'll leave it as an alternate way of saying the same.

Let me ask, has anyone successfully "tabooed" certain words, or do people not understand the purpose of doing so?


I don't use the "taboo" terminology, but I frequently ask people to operationalise their definitions in arguments. ("What specific steps would I go through to test whether the system is scalable or not?")

The first time I ask, people ignore it and/or don't understand it.

The second time I ask, people get uncomfortable because generally they haven't thought about what they mean to that level of detail, and they try to weasel out of it.

The third time I ask, it diverges. Some people give me a reasonable definition. Some people say "sorry that's not possible" and depending on the subject, I pause the argument at that point to do something else.


> The first time I ask, people ignore it and/or don't understand it.

What if this also happens the second, third and Nth time you try?

> The second time I ask, people get uncomfortable because generally they haven't thought about what they mean to that level of detail, and they try to weasel out of it.

Or maybe people decide to stay here, believing their subjective views to be good enough answer for such a question. Then what?


This is where it has paid for me to practise interpersona skills. Once I'm outside of the common situations every situation is unique and I have no general advice.


I don’t think the parent commenter’s intent was that the words be universally banned, but instead context-specific words banned for a specific conversation. It’s just trying to remove implicitly differing definitions.


Typically I just disengage myself from the topic (or the drama/tension that is brewing up) and start asking what people mean when they use a certain word.

We've somehow started arguing about optimisation, for example. Time to take a step back and ask what "optimisation" actually means.

In fact, me saying "let's step back a bit" is pretty much my go-to phrase for saying we've gone too far down a rabbit hole and we should come back up for air.

I don't think I would have much success trying to make certain words taboo. Much better to create a shared understanding of what something means instead of trying to avoid it.


I didn't know this was a thing that had a term either! I don't talk politics anymore except with folks that I explicitly know want to talk politics, but I frequently suggest that people shouldn't use a whole litany of terms in those discussions: right/left-wing, capitalist, socialist, liberal, conservative, communist, libertarian, fascist...so many people use these terms as short-hand for "stuff I really/don't like", and then project values and policies onto them.

Throw them out, talk about the issues, talk about your shared values, etc, and you'll quickly find that you agree with people a lot more than you realized.


I didn't want to mention politics, but "Critical Race Theory" is a prime example and should really be tabooed as a temporary exercise to aid understanding. So many discussions about it without people having a consistent understanding of what it means. I think they've even written laws regarding it without defining what it means. But, sadly, politics is rarely about understanding each other or reaching consensus.


> But, sadly, politics is rarely about understanding each other or reaching consensus

This made a recollection (possibly a lucid dream) about a country who has replaced an (implicit or explicit) adversarial system with one that starts by getting the parties to co-author a document on what they agree upon.

I think this is what our politics (organisational and the representative system alike) should try to implement


Totally agree. Many of these terms mean totally different things to different people. And sometimes contradictory things to the same person. Get rid of the labels and talk issues instead.

And I guess the same is true in the examples of tech discussions where people couldn't agree because "scaling" or "performance" meant different things to different people, because by the nature of their work, they focus on different issues.


So often I see engineers get sucked into arguing something based on a buzzword that they either believe the system they are building needs to conform to, they think other people (outside the company) care about, or because it agrees with their pre-conceived design notions.

Nuking words interrupts this, I often ban the words "scalable", "Automated", "platform", and "system". It forces the conversation back to specifics such as "Ability to handle X requests per second supporting Y users", "Process requires x, y, z steps rather than a,b,c steps", "service supports use cases A, B, C"


Banning those words also makes the conversation easier to follow for people who don't know the jargon. Jargon can be a quick shortcut when everybody is talking the same jargon and is clear about what every word means, but it can become a massive barrier to discussion if one of those criteria is not met.


I have never heard of this approach before, but it sounds flipping great. I will now look for arguments that I can start and then later solve with this method. Winners all around!


> first being specific about what we agree upon.

Or even just trying to define the goal you are trying to accomplish. I've seen many disagreements on software projects because people's definition are completely different. The arguments are just a symptom of a deeper problem that no amount of careful discussions are going to fix.


It is very valuable to be able to spot differences in definitions, so you can address them before moving on. If you feel like you are talking past eachother, that might be the issue causing it.


I have been accused of being dim for not understanding a common word. Or alternatively of intentionally playing dumb.

Then I layout out six reasonable definitions for the word that could fit this context. Then I am accused of making other people feel dumb. Unless it's my wife, who simply claims, "You know what I meant." :)


This might not be the right place to ask..

How to find value from LessWrong? I see people derive value from it, but when I visit it, it’s not obvious


Read "The sequences" [0], may be the Harry Potter and method of rationality book.

For lesswrong (and the Rationalist community in general), I've found that their "broad stroke idea" is what brings the most value. The more in-depth discussions bringing those ideas to specific topics is intriguing to read, but probably much less valuable for daily life.

[0]: https://www.lesswrong.com/rationality


The site has a "curated" feed with articles the moderators deem to be useful.

What value you'll derive from it varies (especially if you're not into AI alignment) but there are a few gems every few weeks.



This seems quite impractical for the real world, since it assumes perfect knowledge, perfect communication and, above all, rationality.


I've often remarked at how common it is to hear two people talking about completely different things using the same words, thinking they're both understanding each other. Communication could be something that we think we're better at than maybe we actually are.


That's why type systems are important in languages.



The one thing that was drummed into my head in grad school was to define your terms. I often ask students "How much is 'most?'" as in "most people think X." Technically 50.1% would be "most" but when I say "most" I generally think closer to 75% or more. So people could think they are disagreeing over whether "most people think x" is true but they are really disagreeing over the definition of "most."


Communication is improved if, rather than redefining terms in common use, you just use the terms in common use that already mean what you want. So if you mean “at least 75%”, just say “at least 75%” rather than “most”, especially if you are negating it in a condition where negating it with the common definition would not be true.


>Many intense arguments can be diffused by first being specific about what we agree upon.

Exactly. Whenever I have the inclination to get into an argument about politics, I try to start by finding a common premise, in order to find where the problems or disagreements start. And eventually, I find that we have similar goals where you wouldn't expect sometimes, but are coming at it from completely different sets of facts that guide us to different conclusions.


This is a great idea. Not just for tech discussions; I think some political discussions would also be much improved if we could taboo certain words. Some people get too hung up on certain -isms without explaining what specific policies they're talking about.


People should do this with the word "decentralized".


Without properly-defined terms, where the participants agree on definitions, it's impossible to have a rational discussion grounded in logic.


"You keep using that word. I do not think it means what you think it means."


Or just ask "what do you mean by X".


This is one of those things "rationalists" do that doesn't always make sense. It is possible to tell someone to "taboo their words" to obstruct someone, in order to make it hard for them to discuss something whose meaning you know very well. It's also possible to tell someone to taboo their words because you want to nitpick an imperfect definition--regardless of whether the flaws in thde definition are relevant to the current argument.


I hereby taboo the words "taboo" and "rationalist"


Sorry to be a curmudgeon, it's a poetic little story - but isn't the takeaway a little banal?

"Different people have different perspectives." Well sure.

"Consider things from others' viewpoints." Of course.

I don't know, it rings a little of management-ese, or something overpaid consultants might present in the boardroom that gets everybody nodding their head and feeling like they've received great wisdom, but is a little hollow or obvious when you really break it down.

It's a good takeaway, even if commonsensical I guess.


You're not wrong, but this ability is not common. Our viewpoint is the core to many fundamental issues, which makes us "both right" which leads to endless arguments because we're both optimising for different things.

A really good example is how one "hears" the news. Some people hear "how this affects me", others hear "how this affects everyone else". There's talk of a minimum wage increase, do you think "yay, more money for them", or do you think "my taxes are going to go up to pay for this."

You see this disconnect every time a customer is upset with a business. They imagine that a business optimises for the customer, whereas a business optimises for the business.

Like when a business is acquired and disappears. Users see this as bad, but owners see it as "I got paid".


I mean, it’s obvious in retrospect. If you’re the type of person who read the first half of this story and immediately went “Ah, I know what the problem is, the kid’s looking at the other signal!” then kudos to you for not needing this advice ever again, but I suspect the vast majority of folks could do with being reminded of common sense things from time to time.


> If you’re the type of person who read the first half of this story and immediately went “Ah, I know what the problem is, the kid’s looking at the other signal!”

I'm that person! :)

But admittedly only because a friend experienced a similar thing when she worked as a kindergarten teacher for three months in Bolivia; a few days in she had a conversation with a little girl who seemed very bright to her in general, but then they talked about how you properly cross the street, and when she asked the girl about traffic lights, she insisted you walk when it's red.

Turned out the town they were in didn't have signals for pedestrians, and since the signals for traffic are positioned like in Europe (ie not the other side of the junction) you had to check the signal for the cars and start walking when it turns red.


> "Consider things from others' viewpoints." Of course.

Difficult to do, isn't it?


Something the IQ measurement is actually kind of helpful for is being able to tell if a person is likely to be able to mentally model, understand the abstract and hypotheticals, or empathize intellectually with others.

If you can model what someone else may think, what someone else thinks someone else may think, or understand "what ifs", your IQ will almost certainly measure higher than 80. An example of the opposite is asking, "had you done this instead, what would have happened?" and receiving a response like "that's not what I did".

I have encountered people in functional corporate roles whose ability to grasp beyond what is directly in front of them was exactly why they held their positions. They were highly competitive of and motivated by metrics, no longer or unable to see how things done differently might produce different results ("that's not how we do it"), and generally didn't have a grasp of how their or their department's work fit into the company - they just knew it did. However, they often had a few great interpersonal qualities, like projecting confidence or leadership, patience and self-control in arguments, not easily being flustered or becoming nervous, or having a consistently positive demeanor.

When I think about privilege and justice, I include the existence of people different from me, which means I have to be aware of and understand who they are and what they are like. There's more than one right way to be or live, and it often comes as a shock to some that their communities, classes, and societies are so effective at insulating them from what people different from them are like, only highlighting simple, shallow, or visual differences instead.

My takeaway is that if the number of people this was helpful to was a surprise, your standard of common is too narrow.


My takeaway (and something I've been thinking about regarding precision in communication) is that people often believe to be talking about the same thing, yet will be talking about different things.

This is super frequent, especially in more heated discussions, and it leads me to want to look at writing things precisely, even the banal stuff, so that we can actually figure out what is going on. This is especially helpful in the "I can't believe you actually think that" cases


I think its pretty common, especially when building software for other people, to make all manner of invalid assumptions. This is a nice, succint story to demonstrate how easily things can get over our heads. To ground it a bit -- if people aren't buying your product, or aren't using your feature the way you expected, you try to understand them. But if they or the world don't make sense, you might need to more literally get into their shoes to figure out why. How often on HN do we see people complaining that what someone does makes no sense. Whether another political party, upper management, non technical people, etc. Its actually the main thing that drives me away from HN at times, because those comments never go anywhere substantive.


Maybe she meant that there was a lot more research needed before she understood him.


Yes, but that's not how we _learn_. You can read all the succinct bullet points of advice you want, but seeing a lesson explained through the eyes of an engaging story is a strictly better way of _ingesting_ said lesson and makes you more capable of actually pattern matching situations where it is appropriate.

"Consider things from others' viewpoints" is a summary of the lesson, but you could have told that to the mother in the story all day long and she wouldn't have grokked how to apply it to her situation, or even that she would benefit by doing so!


I mean it is a quote from a guest on the Tim Ferriss podcast. Not exactly a font of anything other than received wisdom and LinkedIn platitudes.


For me, the takeaway is pretty deep:

Other peoples world views are valid.

It's so easy and so human to criticize other people's views, filtered through my own world view. But then I'm really only criticizing own interpretation of their view.

For me, this is a lesson that almost can't be repeated enough, because I tend to slip into forgetting about it.

But good for you if you find it obvious and banal :)


It is banal but people often forget about banal things.

Especially in technical discussion where they are focused on "important things that everyone should already understand".

Then it turns out that simply asking to clarify assumptions helps a ton.


Yeah, posts like this getting a lot of upvotes makes me feel like I don't understand how humans operate these days anymore.


It's weird it took her so long to realize what was happening - I knew as soon as I read the first paragraph what was going on.

I suppose it's because I am younger (and thus have memories of being a kid) and was rather short as a kid, so I know what sorts of limited visibility you can have as a kid, and more recently I'm also used to driving at confusing intersections where it's not clear which light applies.


Your comment was the top one and it encouraged me to just click through to the article and... I just don't get it after the first paragraph. Indeed, colour blindness? But that doesn't make you "know" it wrong, that makes you not be able to tell (afaik). So then... the kid was either joking, had learned it the wrong way around, or tied the name 'red' to the bottom position perhaps.

... turns out it's a localization problem. If you're sitting too low at the front of the queue, you'd see the overhead traffic light often better than the drivers do. I didn't think that this must, of course, be another USA-localization story and the traffic lights are elsewhere over there (across the crossing I guess).

> used to driving at confusing intersections where it's not clear which light applies

and I guess that explains why there are different systems. Why not change them around in the USA as well? It's not as if people could be confused and look at the wrong lights, as the others' lights are simply not visible when the lights are all on the side nearest to the lane(s) they apply to.


I'm not sure if you caught this or not, but I think the actual key to the story is that the child in the rear seat of the car and looking out the side window at the light for the stopped crossing traffic. Unfortunately for the anecdote, the "rear seat" part isn't mentioned until the 4th paragraph: "So I was in the back seat sitting next to Ben".

I think the issue is that in the US, all children below some age must be in a car seat, and in some US states, that car seat must be in the back of the car. The author presumed that by mentioning her son was 3 at the time, that her audience would automatically understand that he was in the rear of the car. Even as an American, I didn't.

I think it would make a better story if this was made explicit.


You ever seen a 3 year old in the front seat?


Yes. I'm 50, and grew up before the common use of car seats for children. Children of all ages would commonly ride in the front seat, or even in the back of pickup trucks. Even today, only about half the states have rules specifying that the carseats must be installed in the rear: https://saferide4kids.com/car-seat-laws-by-state/

As a fun anecdote, my father grew up prior to the time that most cars even came with factory seat belts. Before taking a family trip to Alaska in the 50's, his mother read about them and demanded that her husband install them in the station wagon before the trip. So he bought straps and buckles of some sort from a hardware store, and bolted them on so that all 6 kids would have "seatbelts" for the trip.


But you're 50. I'm 55, and for the large majority of my life (and presumably smaller than yours) kids were relegated to the back seat.


Remember getting stuck with the "hump" in the middle of the floor? I guess it was only a problem if you have more than one sibling and your parents had rear-wheel drive.


These laws are regulated by the states and vary widely:

Child Passenger Safety Laws in the United States, 1978–2010: Policy Diffusion in the Absence of Strong Federal Intervention

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3899584/#!po=1....


Maybe state dependent? I’m not yet 40 and recall being excited that I could finally ride up front when I turned 3.


At 3? You've got a damn good memory


Only a handful of vignettes from 3-5 but the excitement of riding in the front seat was enough to cement that one.


Hmm, I know car seats weren't always as big a thing, but I think it's pretty rare these days for a 3 year old to be in the front seat. Am I the only one who would instinctively feel it was unsafe? I feel like this would have been obvious even before I had kids and was basically clueless about their safety.

Yes. Up to a few years ago, I would often see rear facing car seats in the passenger side. It makes it easier for the driver to reach out to the toddler.


> Why not change them around in the USA as well? It's not as if people could be confused and look at the wrong lights, as the others' lights are simply not visible when the lights are all on the side nearest to the lane(s) they apply to.

As a German in the US, I find the positioning of traffic lights to be one of the very few traffic-related this that are better in the US. In Europe I find myself frequently leaned forward and looking up at the traffic light to see it at all. I never have an issue seeing the traffic light in the US. Figuring out which light is yours very rarely is a problem. At least not on the west coast where you usually have grid patterns.


> In Europe I find myself frequently leaned forward and looking up at the traffic light to see it at all.

Yeah that's exactly the issue I meant. I've never seen anything else though, so I don't know if it's better or worse. Just that the person I was replying to said they were sometimes confused by the US system.

I guess my approach to all this is to not drive as much and especially not much while in cities where there are traffic lights .. and public transport options. But if you've moved to the USA I suppose that's probably just not an option for you :/


I still remember the moment I realized (maybe at age 5 or so?) that even the cars coming toward us on the left side of the road were driving on the right side of the road from their perspective.


I don't think it's an age thing, I think it was just bloody obvious. So much so that I suspect that story was embellished a lot of dramatic effect. ie the author figured it out themselves quicker than they claimed to but it wouldn't have been as dramatic read if it was the literal sequence of events. Another oddity was the suggested age: 3 years old is very later to be teaching your kids the different between red and green.

Also worth baring in mind that the story happened roughly 20 years ago and I certainly can't remember every conversation I had with my family 20 years ago.


That's funny since I am older, and I sat in the front seat of the car my entire childhood; there were no car seats. When my mother had to make a sudden stop she'd hold out her arm to keep me in place. I remember being dazzled by the arrival of a light with 5 signals (yellow and green arrow and circle) and begging to stay in the intersection to watch them all cycle.


Isn't this just another example illustrating her point?


wow, I am exactly opposite. I didnt realize until I read the full story. I am in my 40s and didn't have car until I was in my 20s and actually rarely sat in one because of abundant public transport at the place where I grew up.


Something about the context--this is a short article posted to HackerNews--makes it easier to realize. I already had a feeling that the story was leading to the adult being wrong somehow.


As a kid my mom ran out of gas several times, and it was always on the same road, which had a gravel shoulder. We'd be riding along, she'd pull off into (what I call "the rocks"), the car would stop and she'd say "we're out of gas". Since the car was moving along fine before pulling off the road, and I had no concept of how cars worked, I made the connection that pulling into "the rocks" caused the car to run out of gas. After making that connection, I used to scream not to pull into the rocks when she ran out of gas. My parents eventually made the connection as to what I was thinking, and instead explaining how it worked used to tease me with it well into my adult years.


Earlier today I mentioned to my first grader that when I was a kid we didn't have an ice maker in our freezer, and we just used ice cube trays, instead. He sat there for a minute, stumped, and finally asked, "so what made the freezer cold?"

It took me a minute to figure out what he meant, but finally I realized that he thought the way our freezer worked was that we had a machine that made ice, and the freezer was cold because it was full of ice. It's really easy to reverse cause and effect when you can't see what's happening.


When my daughter was 5 she told me off for driving too fast to school. She was annoyed that whenever I drove fast she would be late for school.


In a sense, she was telling you to stop being late to school :)


I got a similar teasing because I used the word "lightricity". Too too long ago to really know where/why my brain locked into that word. Lights=>electricity=>lightning, it all gloms together.


This anecdote is a ridiculously great example of something I’ve found to be VERY VERY IMPORTANT with parenting (and probably lots else.)

You must be incredibly delicate with “wrong” answers otherwise you might gaslight, discourage, or otherwise mess with your child’s ontology.

I’ve learned to ask “why do you think that?” When I get a “confident wrong answer” as I call them. A surprising amount of the time my child has some very rational explanation.

Someone once told me, “most arguments among engineers boils down to communication. Usually you’re not arguing about the exact same thing.” These moments with my child really made me grok that.

I wish “being wrong with an explanation” was rewarded the way it should be when I was a kid.


Note that (AFAIK), for adults, "why" can get you the wrong response (puts people on the defensive), so (AFAIK) it's recommended to use "what" instead (which tends to get at the "why" you wanted in the first place) -

"why do you think that?" -> "what led to you thinking that?"

:shrug: It works, sooooo.


I also stay away from second person:

"what led to you thinking that?" -> "what led to that thought?"

My preferred version: "what was the motivation for choosing that?".

It's especially helpful on a team working with legacy software. Because the root cause can sometimes be a historic team decision, no longer attributable to anyone on the current team. Where "led you" can result in the "oh it wasn't my idea" responses, rather than "I think they made that decision because ..." responses.


This is great. I also often go with something like "can you explain that to me?", because it puts the focus on my apparent lack of understanding the thought process rather than the implication that there's a deficit in the process.


>what was the motivation for choosing that?".

That had the second person in it, it's just obfuscated with less-than-clear language. "The motivation" belongs to, and is exclusively controlled by, the second person.


> That had the second person in it,

It can have* the second person in it. It's up to the otherperson if they want to answer in with their motivation, or the team's motivation, or explain that they weren't told the motivation by <owning person/team>.

It gives me a lot of information about the person answering, and the problem at hand. For example, if it was a team motivation I can follow with "and what are your thoughts on it?". If it was "my motivation" I can follow with "and what does the team / <so and so> think of it?". If they don't know the motivation, I can follow with "Who can we talk to, to find the motivation?" help them learn this is an important part of being a great software engineer.

Anyways, it's just my preference, regardless if it "technically" has the second person in it. Your milage may vary.


No it is not. The motivation and choice belong to some person, the grammatical "second person" refers to you especially and no one else. Sure in some situations there is no one else who motivation and choice could be attributed to, but in many there are. Anyway this is about a rhetoric trick: avoid attribution to the person you are addressing to reduce the chance of them going defensive, denying responsibility, trying to wiggle out of blame, and instead answer the actual question. In a more general sense avoiding such details increases focus.


"How do you know".

But anyway, I don't think it matters that much.


Oh that's excellent, thank you!


I've been using "How did you figure that out?" which I got from Marilyn Burns and her wonderful interviews with kids.[0]

Her videos are really cool to watch — often the kids will self-correct their wrong answers when talking through their reasoning. Even if they make the same mistake the second time, it gives the listener really great insight into how they're thinking about the question.

And it's a great question to ask when the kid is right too — often I'm surprised by my son's answer, such as when he figured out how to spell "only" by looking out the window at the right-turn only sign painted on the street outside.

Why is clearly a personal judgement. What is something other, not the person, and we can even possibly feign objectivity and share a point of view of the matter.

Like the saying goes, nobody likes a "whys guy."


Please don't. Euphemism treadmills destroy langauge.


It seems to me that euphemism treadmills also create language.

That doesn't mean we should permit them, but there should be a better reason than "this will lead to change".


I prefer "What makes you say that?"


This makes me recall the time I was riding on the bus, and there was a little boy (maybe 4 years old) with his mum. The little boy was proudly reading the numbers off the other buses he saw drive by.

"7, 23, 5, 86," the boy proudly stated. Then a bus numbered "5X" came by.

"What's that?" The boy said, pointing in confusion.

"That's the bus number!" his mom said.

"X is a number now?" the poor kid asked in a painful tone. You could just hear his understanding of the world crumbling around him.


Still happens to me as a programmer when diving deeper into the domain.

Just to continue on the "number" theme: that address-form you recently built is probably wrong: https://en.wikipedia.org/wiki/House_numbering

(where "wrong" is considered in the larger domain. It is probably "right" for your use-case and niche-domain, though. E.g. where you are certain you'll never ship to Thailand. Ever)


This why I evaluate future coworkers (interviewer or interviewee) on the speed at which we can align mental models. I have worked with some great engineers with whom I felt like bashing my skull in trying to get them on the same page, and some very middling engineers with whom I was immediately able to understand. Maybe I'm an idiot, but I would rather work with someone I can communicate with than an unapproachable great.


I think it would be worthwhile to ask "why do you think that?" on some confident correct assertions as well. Will help with collaborating on developing the child's use of rationality in case they're right for the wrong reasons, and also to avoid overly associating being asked why with being wrong.


I’m more impressed that James was able to just write up an excerpt from someone else’s podcast and make it to the top of hacker news


The post adds value because it's significantly easier to consume than a timestamped link to a podcast.


Yes, this seems like a really "low-effort" post for an otherwise very technical and demanding audience.


The problem with this analogy (as the author ties it up to the end point) is it implies you're leading a team that simply can't see the reality.

More often, the change in perspective allows the person in the back seat to see the car that is about to run a red light and smash into you, rather than it being a question of presenting them a better context.


The child wasn't seeing something that wasn't real. The child was looking at a different light. The miscommunication occurred because neither realized that they were looking at different lights.


> it implies you're leading a team that simply can't see the reality

If everyone on the team has the same level of visibility into everything, there is insufficient specialization and/or utilization.

The child in the analogy wasn't blinded from seeing the light ahead. He could theoretically access that information. But in practice, he didn't, and that lead to a miscommunication.


I don’t think the story takes a position on who is right at what level (and, in fact, it sounds like the story teller herself concedes that leadership should be digging into why their teams are saying “red light” when it’s a green light).

I think the story should be ingested as “we don’t know why someone else can’t obviously see what we see; that problem itself warrants investigations perhaps before any conversation about what to do next.”

As it turns out, our company is currently having this problem: the market and employees of my company are screaming at the leadership to not follow through on a business plan, but leadership has their head buried in the sand and are bound and determined to move ahead because all they see is green lights.

And sure, there’s enough anecdotes out there about people zagging when everyone else zigs, but I think an unspoken prerequisite to those anecdotes is that you at least made sure you understood why they were zigging.


I had a very similar experience as a child. I always wondered how other drivers could tell which way we were turning. My parents told me that they can tell from your turn signal. 6-year-old me just thought turn signals entailed the green flashing arrows on the dash (not also on the car’s taillights). I just assumed all drivers were tall enough to see into the other car and tell from their dash (for at least the next year or so)!


Funny, I remember as a child wondering how my parents knew how to get where we were going. I saw the green lights on the dash (and couldn't see the signal lever from the backseat) and just thought that the car was smart enough to give them directions.


You were right eventually!


My child perspective story;

When we were young we watched a TV program called Play School. We always watched it when we got home from normal school. Mum put on the TV and on came Play School. I didn't understand until much later that the act of turning on the TV didn't 'start' the program, so if, for whatever reason, we got home early I used to get super frustrated with my mum for not turning on the TV and letting me watch Play School straight away.

Mum never took the time to understand why I was frustrated.


The amount of on-demand kids content these days makes this even trickier now. I frequently have to explain to my kids that no, I can't play that song again because this is the radio and we can't control what it plays.


The book "Difficult Conversations" coauthored by Sheila Heen and referenced here is an incredible read. If the OP is interesting, I highly recommend you read the book. It seems it was written for people with analytical minds. I have memorized the steps and am in the process of internalizing the self awareness required to be effective in this area. Hard but seems really worth it.


My take after reading this is a bit different than the others.

I think it's absolutely insane that a three year old has to learn traffic rules to not be mauled to death by passing cars. What a fail of society.


Even in countries with zero child deaths due to traffic, children need to have some traffic sense, and that's part of what helps keep the accident rate low. Cars exist and a child running into the road unexpectedly can still be injured by the safest possible car driven by the safest possible driver. Learning to cross the road is a basic skill children benefit from learning.

Having traffic sense also gives them more freedom and a better roaming range. My son was very traffic conscious from a young age, so I could let him run ahead on the pavement and freely run around small parks near roads. Other parents held their kids close because they were constantly worried they would run into the road. My son started walking to school at age 7 as he knew how to cross roads. These things gave him a lot of trust & freedom early on than other kids don't have.


This is the norm in many places in Europe and elsewhere. 6 year olds walking to school by themselves and crossing multiple roads on the way.

America is a bit different. It is also built completely differently when it comes to car-oriented infrastructure.


As someone with a child the same age, I see it very differenly.

The way I explain it is that traffic lights, roads, crossings, etc, are a mechanism by which society co-operates. Everyone's trying to do something a little different, and if we work together and buy into a shared understanding then we can all do what we want to do. That's a really positive thing. We can all get on with what we need to without resorting to ideology which isn't relevant to the task at hand.

Also, I think it's important for children to learn about everything around them, to see how the world works. It's irresponsible to leave a black hole of knowledge. Especially for things that can be dangerous. Mine knows all about volcanoes, dinosaurs, power tools, chisels, hammers, etc. And he's learned how to interact with at least some of those safely.

Otherwise it's quite literally learned helplessness!


It's not co-operation if one part lives at the mercy of the other.


They are mostly a mechanism by which car drivers ensure they don't run over other people.


A 3 year old shouldn't be in traffic unsupervised of course, but it can't hurt to help them understand what's going on around them. Even at age 3, kids are interested in that stuff. And eventually they do have to learn this, and by the time they're old enough to be in traffic unsupervised, they should already know it. So you start early.


> And eventually they do have to learn this

Yes. But they shouldn't have to. It's just a testament to how car-infected society is, that you have to move around based on their demands. Why should a car be able to drive straight through my street, while I have to go out of my way to find a safe crossing? It should be the opposite.


That is absolutely true. I'm all for car-free spaces, and an abundance of safe crossings. Although for any crossing, "safe" still depends on the responsibility of the car driver; I always point out to my kids that even if they do have right on way on a zebra crossing, they still need to watch both ways.

Still, cars or not, there will always be dangers, and you're always going to have to teach kids how to deal with them. I live in a former docks area; lots of water, and my youngest still doesn't have a swimming diploma, for example. And even bikes can hurt you if you are careless around bike paths.



This story highlights the value of putting yourself in the mindset and perspective of the "other" that you disagree with, to see things their way, for your own benefit.

The entire Tim Ferris podcast episode (from which the quoted story was told - https://tim.blog/2021/09/09/sheila-heen/ ) is good, and brought to mind an EconTalk podcast episode that explores how seeing and doing things in the interest of others is many times in one's own best interest in the long run:

When I was very young I couldn't say "milk". I called it "momo".

But I could say "homogenized".

So I'd ask my mom, "Can I have some homogenized momo?"

She would reply "Do you mean homogenized milk?"

I answered "Mom! I can't say milk!"


When my brother was very young, maybe 4 or 5, he wanted to get McDonald's one day. My mom, for whatever reason, didn't want to and told him McDonald's food was too greasy. He insisted that it wasn't greasy at all. My mom told him it was. This went back and forth with him getting more and more upset until he finally screamed "GREASE IS WHAT DAD PUTS ON THE WHEELS OF THE CAR".

My Dad always did all his own oil changes and lubed the wheels with a grease gun. My brother had watched him do this and was furious that he thought my mom was insisting that the thick axle grease that came out of the grease gun was what was on McDonald's food.


I think this highlights the necessity of patience and compassion in everyday interactions. Sure I might be more experienced than my junior devs and sure, often times I have access to the broader picture and direction of the project but if they come up with something that runs to the contrary, the least I should be able to offer them is considerations on my part. As in, sit with them, try to understand why they think that way. This will have two possible effects:

1. I'll know that I have not been communicating enough with them and they are making inferences with limited or distorted assumptions.

2. I have been making incorrect assumptions or inferences.

Needless to say, both of these have their own values. I think this is what is necessary in a teacher as well. Lots of time we say that people with genius thinking does not make a good teacher because they automatically arrive at the correct answer and are usually baffled by those who aren't able to do so. The genius required to be a teacher is the ability to predict the different (and not necessarily correct) ways that people can arrive at a conclusion and identify why and which path someone took for a particular problem... and be kind about it.


I wish I wrote down all these kinds of things my kids have said. One thing I remember is my daughter explaining, full of confidence, to her brother that in summer the ice sinks to the bottom of the canal and it comes up in winter. Which is a very good hypothesis if you don’t know about phase changes in matter.

Kids always say these kinds of things because the models of the world in their little heads are incomplete. But then, for who are they complete, really?


I'm always amazed at kids ability to quickly build hypotheses and communicate them. The one you mentioned is actually a great one and I wish people wouldn't stop doing that after they grow up. I find it very similar to what actual scientist do on the frontiers of knowledge, where no one really knows, what correct really is - yet.

I wonder how the kid would react, if they saw the bottom of the canal in summer somehow -- missing the ice


Yeah exactly, I always try to (make them) come up with an experiment that would show if they’re right or not. Honestly it’s a challenge and my wife always points out that the kids have stopped listening. I need to learn to stay brief… It just happens so little that I get too excited when it does.


Great story but what's with the fixation on fault? It's nobody's fault if a genetic trait is inherited, there's no control over that.


It was the first thing I noticed as well, the blame. It was like "blame the husband" was the terminal state of sorts, solving the issue somehow.

Of course the anecdote is about changing the perspective, but I think there's an obvious elephant in this room as well


You could argue if incest is morally bad then so is procreation when you have negative inheritable traits and know about them. It gets ugly pretty quickly from there though.


> maybe he’s color blind, which then that would be my husband’s fault

I've just discovered a huge deficiency in English. In my native language I've got a perfect response:

I'm not guilty as I didn't broke any law.

Which goes along with both classical nullum crimen sine lege and with UN's Universal Declaration of Human Rights no less:

> No one shall be held guilty of any penal offence on account of any act or omission which did not constitute a penal offence, under national or international law, at the time when it was committed.

The problem in English is the word "fault", which can mean both "a physical or intellectual imperfection" and "responsibility for wrongdoing" among its many meanings. Phew, try to defend against that, accusation of not being perfect.


The Chinese for traffic light is red-green-light (hónglǜdēng).


Interesting. It's 신호등(shin ho deung) and 信号灯(shin go tou) in Korea and Japan. Both literally meaning signal(信号, 신호) light(등, 灯), so I would have thought Chinese would use something similiar (I can see 灯 is being used). I wonder why that happened. Maybe because red is an auspicious color? Or maybe because the word may have originated from Japan and they wanted a different word? or maybe simply because that's what people started to call it and it stuck?


An excellent post that illustrates a common problem of perception. For those questioning some of the statements being made I just wanted to point out that the storyteller is probably engaging in hyperbole in order to help bake her point clear and persuasive.


I often realize that I'm caught in a conversation where we don't use the same terms/concepts.

The hard part becomes getting the other person to slow down and actually explain their basic premise.

People can get defensive no matter how you ask them "What do you mean by X?", and worst of all they sometimes have a fixed route they want to take and are just giving some pretext to justify their actions.

I do my best, but I've never seen any framework that consistently works here (has anyone?), so I honestly think we need to work on this on a socio-cultural level. It might help with couples as well.


What often helps is if you frame it in a way that shows you as the less knowledgeable person, that way people tend to feel less "attacked".

For example: "I didn't understand X, could you explain (again) what you mean by that?"

But in the end, I guess the more important thing is to build up enough trust between the teams, that one isn't constantly driving the attack/defense line, but can openly talk about ideas and see questions as clarifying, rather than attacking.


Point of View and context are some of the most important things in communication. You can't remove point of view and have a conversation.

Some of the hardest work I do is trying to understand what colleagues are saying.


> perhaps the problem has nothing to do with communication

Going for experiments and research and never further discuss the situation with the kid feels to me like it has everything to do with communication...


I immediately guessed why, but for a slightly different reason.

Some people when driving (e.g. me) have an unfortunate habit of looking at the other lights, to anticipate the green.

I thought perhaps that the kid was watching the parent's head direction. In fact I suspect that this is the real answer. Lights aren't typically that hard to see ahead, even from the back seat.


I'm glad I'm having these traffic light discussions with my kids on foot or on a bike. That way I can be sure about what they can see. Or when we have it in the car, it's when they're in the front seat at least, but I'm a poor enough driver that I'd rather focus on traffic than try to teach my kid while driving.


It makes me think of the first slide in the first episode of Sliders where Quinn Mallory slides, thinks his machine failed, then realizes he slid into a world where the red light means go and the green light means stop and someone yells at him "Don't you know you're supposed to stop at a green light?"


I developed a habit of looking at the cross traffic light to be "ready" for the upcoming green. I thought I was being smart and then I started noticing other people doing the same. Now I think just looking at the light directly is the totally fine obvious thing to do instead of this over-eagerness.


Lots of people are taking away "be kind when you listen to others' perspectives", which is right.

But another point we can take away from this is: finding & amplifying the people who see colors that other people can't see — is a really valuable thing we can do, both for those people and your team.


My four year old just did this to me yesterday. I went through an intersection and he said, "daddy you just went through a red light". I got freaked out because it was an empty intersection but then I saw someone else go through and realized it was looking out the side window!


Rather than a lesson about perspective, my take away is about the resilience of the self-supervised signal, i.e. the child relying on sense data, even when the strongest of supervised signals is contradicting it, i.e. the mother/teacher.


"A change in perspective is worth 80 IQ points" - Alan Kay


That's cute, I have no idea what window the GOP is looking out of...


This seems like an external real world Schrodinger's cat.


I love that the first reflex is to blame the husband.


Never miss an opportunity to quote Marx: "Being determines consciousness!"

;-)


>>Now just think about the conversation from his point of view.

Bad parents don't do this one simple thing.

Please don't post unsubstantive comments.


Ha, fictional stories are so much better right?

> This woman comes off as incredibly weird and arrogant. Her first instinct is that her son is color blind, and then her next immediate instinct is to assign blame to her husband for that? She then goes on to run "experiments" on her child _FOR THREE WEEKS_ rather than just ask him a few simple questions that likely would have eliminated the confusion.

Why so judgemental on the mom, butwhywhyoh?

Being a parent is a difficult challenge in the best of circumstances. She's not claiming to have been an adept empath-of-children, so I don't understand where this is coming from.

Is it possible this speaks more about you and your parental relationships?

Half-joking here, if at all. This is an extremely common behavioral-baggage pattern that most of us hu-mans carry with us one way or another.
