You ever see a dog that’s got its leash tangled the long way round a table leg, and it just cannot grasp what the problem is or how to fix it? It can see all the components laid out in front of it, but it’s never going to make the connection.
Obviously some dog breeds are smarter than others, ditto individual dogs - but you get the concept.
Is there an equivalent for humans? What ridiculously simple concept would have aliens facetentacling as they see us stumble around and utterly fail to reason about it?
Rejecting evidence that is right in front of our eyes because of some kind of religious faith or political beliefs.
Thinking that tailgating the vehicle directly in front of them will make thousands of other vehicles in front of that vehicle magically go faster. And many other reckless car-brain stunts.
Is this the root pathology behind traffic? Like, I never understood traffic, is there someone at the front refusing to go fast enough or is it the result of some distributed error like this that everyone mis-optimizes for that in aggregate results in traffic?
Based on a game* I think that the root issue is that there are multiple bottlenecks, unavoidable for the drivers, like turning or entering/leaving lanes, forcing them to slow down to avoid crashing. Not a biggie if there are only a few cars, as they’ll be distant enough from each other to allow one to slow down a bit without the following needing to do the same; but once the road is close to the carrying capacity, that has a chain effect:
- A slows down because it’ll turn
- B is too close to A, so it slows down to avoid crashing with A
- C is too close to B, so it slows down to avoid crashing with B
- […]
There are solutions for that, such as building some structure to handle those bottlenecks, but they’re often spacious and space is precious in a city. Or alternatively you reduce the amount of cars by discouraging people from using them willy-nilly, with a good mass transport system and making cities not so shitty for pedestrians.
*The game in question is OpenTTD. This is easy to test with trains: create some big transport route with multiple trains per rail, then keep adding trains to that route, while watching the time that they take to go from the start to the end. The time will stay roughly constant up to a certain point (the carrying capacity), then each train makes all the others move slower.
Traffic is a numbers game. I’ve often observed that in free flowing traffic where I live (a tiny city with only about 700k people in the entire metro) that if you take two cars that are a safe following distance apart there will be 5 cars in between. If we put in 6 times as many lanes (already a 3-4 lane freeway each way, so we are talk 20 lanes for my tiny city!) traffic wouldn’t go any faster, but they would space out to most maintaining a safe following distance. (if you put in 7 times as many lanes they would get farther apart yet, but still not go faster)
If I’m understanding correctly, your example wouldn’t apply to a highway that is experiencing heavy congestion.
It would, but worse. Both are a case of more cars than there is space. Heavy congestion would just need a lot more lanes to fix - maybe 10x as many. (don’t ask me to pay for that or where those lanes go)
Or in short, support better transit for your city. For that cost of miles of 15 lane highways you can put in a lot of transit.
Transit? PUBLIC transit? Wow that sounds a lot like socialism! Why do you hate freedom?!
/s
No, PRIVATE transit. I don’t support the government building roads - that is meddling in the natural state of things and makes private industry unable to compete. If you must have socialist roads than you must have socialist transit as well, but I reject that.
It may be helpful to think of it as a stream or a river, and not a collection of individual drivers. We can only control ourselves, not the stream. People working so hard to put themselves and others at risk are maybe shaving a minute or so off of their commute. Just not worth the risk.
I just drop a mph every couple seconds until they fuck off. Don’t break check, as that’s super dangerous for you and everyone around you; don’t change lanes to accommodate them (unless you’re the source of the bottleneck and camping in the fast lane, in which case GTFO), since transitions are when accidents tend to happen; but you can absolutely slowly annoy a tailgater until they leave your bubble.
If you do this in the left lane and cars are passing you on the right, you in fact are the asshole.
Very strong emphasis on the “unless you’re the source of the bottleneck and camping in the fast lane, in which case GTFO” part of my post!
Sure, but I’m the guy doing the speed limit in the right lane.
LOL, I also do the passive-aggressive slowdown thing. 99% of the time it works. But then there’s that rare psycho that refuses to get off your ass just to…uh…prove a point…by slowing themselves down? There was a post on schmeddit several years ago where a guy came to a complete stop in the middle of nowehere with the tailgator just sitting 1" from his bumper.
Or constantly inching forward at a red light as if you moving the extra 5 feet will make any significant difference in the time it takes for you to get where you’re going.
My favorite are the red light racers who have to pass me while I’m going the speed limit and zoom to the next stop light… Just so they can wait at a red light longer than I do.
A friend of mine calls that “racing to stop”.
Sadly it works out for them overall. It only takes a few times of getting to the next light as it turns yellow and they are way ahead while you are sitting there at a red light. Sure sometimes you get to see them when it doesn’t work out, but when it works out they are long gone.
Timing traffic lights is a hard problem.
We saw on mythbusters that tailgating is really good for fuel economy so we’re all just amateur scientists collecting data.
At highway speeds, tailgating 10 ft behind a 53 ft tractor-trailer will net you about a 39% boost in fuel economy. And further your fuel usage will drop by 100% after the trailer flattens your hood from a sudden stop maneuver!
Also, the closer you are to the trailer, the safer you are! Because the speed difference is much smaller, when you touch the trailer!
Capitalism isn’t purpose and purpose doesn’t exist.
Many people, including myself, are too dumb to understand that other people don’t value the same thing in us that we value in others.
You see them try and become what they like, in order to try to appeal to others. “Well I wish I got more attention, so I’m going to give tons and tons of attention to others”. “I wish someone would make a grand romantic gesture to me, so I’m going to do that to someone else”. That kind of thing.
This is sometimes called “fundamental attribution error” although I think that concept covers a bit more ground.
This is not the fundental attribution error. The fundamental attribution error is seeing an action from a person and assuming it is a fundamental attribute of them. Literally in the name. E.g. you seem someone being rude in public so you assume they are a rude person. Meanwhile if you are rude in public you chalk it up to being in a bad mood as a result of something that happened to you, not because you are a rude person.
It’s really similar to the fundamental attribution error, though, as you can see if phrased this way: “I value $foo by a certain amount because I’m a human being, thus other human beings value $foo as much as I do”.
This is the most charitable interpretation of why guys send dick pics
I think it’s exactly why they do it
I’m a guy, I received unannounced boob pics, that EXACTLY what men sending dick pics want.
Probability. If something has a 50% chance of occuring, that does not mean it will happen every second time, and our brain has a very hard time rationalizing that. For example, we assume its near impossible to flip heads on a coin three times in a row when really, the probability is 12.5% - not that low. Another example would be something with a 95% chance of success - we naturally round up and assume thats basically garenteed success, but theres still a very decent chance of failure, esspecially on repeat attempts. Our brains are just not wired to handle randomness well, which is part of why gambling is so addicting and why games like X-Com have to rig the odds in the players favour to avoid pissing them off.
And that past random events have no influence on future ones.
If a coin landed on one side ten times in a row, it’s still a 50% chance on the next throw. Something a lot of people have trouble with.
This is my answer as well.
We have developed intuition around things like naive physics - you can catch a thrown frisbee without doing calculus in your head - but it’s really, really hard to think through statistical questions in an intuitive way.
It’s one reason I’m extremely skeptical about the utility of informed consent in medicine. A physician can tell a patient’s family that if they don’t do the procedure then the patient will definitely die, but if they do it there’s a 20% chance of complication A and a 5% chance of complication B. The right thing to do is plan on the complications happening and having a realistic idea of what that will entail. But people, especially under stress, really aren’t able to deal with that kind of thing as easily as they can deal with catching a ball thrown to them.
The existence of poverty/hunger/homelessness in a post-scarcity world. if we wanted to eliminate those problems we could, but humans are blocked on how it can be done without hurting their own wealth.
Under capitalism, food isn’t produced to eat but to make profits. When it’s not profitable to sell, they will rather dump foods, starving the people rather than to plainly donate. We produce enough foods to feed the entire population. But the sole purpose of food is to not feed the people, but to feed the greed of the producers, the farmers, the corporates. Capitalism created an artificial scarcity of food where we produce too much food for the obese and throw the rest away to rot in front of the poor.
🍇 😡
We’re not yet in a post scarcity world. We’re tantalizing close, but not quite there yet.
There are three main areas we need to work on.
First is power generation. We need more, and it needs to be decupled from fossil fuels. Nuclear is the obvious answer for massive amounts of power output without using massive amounts of land, but fossil fuel lobbies have been hamstringing development since the 50s.
The important thing here isn’t just replacing fossil fuels. That would just leave us were we are now. No we need to double or triple world power generation as a start.
The second area that needs work is connected to the first. Transportation. Not just electric cars, but container ships and trains and everything in-between.
This is where that added power generation comes in. We need to make it basically free to move things from point A to point B. There are some ways to do this, particularly for container ships. But we need the raw power available before they become viable.
The final area is automation. We need more. Once people need to be put out of work in massive numbers. We need to decuple work from life.
That final step is the hardest with the most pitfalls. It will happen. Well, the automation and unemployment will happen. After that we can either spiral into a hell scape or rise above into a post scarcity utopia…
It really depends on when and how the guillotines come out
You’re right, and I suppose I was half-thinking along the lines of “we have all the pieces to solve this, but we don’t because we’re frozen in place by greed” instead of “this is something we could do with infrastructure today”. If everyone could collectively let go and re-distribute wealth and materials efficiently everyone would be much better off for it, but instead we’re stuck in some game theory hell where the optimal personal choice results in one of the worst outcomes.
Despite it being parroted by the terminally online, we do not live in a post-scarcity world.
Humans totally ignore that they are part of nature. Most think that reduced biodiversity won’t include them.
In a lot of ways we aren’t though. The vast majority of people spend the vast majority of their time in a built environment of some type.
Even when we’re in the “outdoors”, most of us spend most of our time on manmade tracks or paths.
We engage with nature on our terms in a way that is very unique.
I kind of feel the opposite. Most people I know is wary of “destroying nature”.
I think meh. It is just getting streamlined. We are getting for the next phase of human civilization. We are more like an organism with white blood cells and well separated and controlled compartments of bacteria filled sacks. It is bound to get more homogenous.
Higher civilization means the meaning of biodiversity will change domains.
Earth is the only planet that we’re adapted to live on. Nowhere else will be as forgiving of our mistakes.
I suspect that colonizing Mars (or wherever else) will turn out to be much more than just an engineering problem. If we get things like food, water, atmosphere, and even gravity right, I think we’ll still find an endless list of requirements that we didn’t know were requirements… and some mystery problems that don’t seem to have any cause at all. Those problems will be because of factors we never thought of, or don’t even know how to detect.
There could also be surpluses/deficiencies in our diet or environment that will take years (or perhaps generations) to show up. Again, that would be because of unanticipated, and maybe unsolvable, problems.
We for sure will need to exercise, because low gravity turns our muscles into mush.
I remember sitting in on a briefing from the Biosphere folks when they reached out for collaborating institutions. One of the things that stuck with me was that they discovered that trees that were not subject to wind failed to develop a healthy trunk and tended to fall over and die. That’s not something that the researchers had even thought of.
I suspect that there’s going to be a lot of that.
Interesting! Plus, that’s exactly the sort of weird, unanticipated thing I’m talking about. How do you plan for everything? You can’t.
The first human colonists (who are just ordinary people) won’t be the rich. They’ll be desperate people who are sold a dream of the future and treated as human lab rats.
4D baby
We live in 4D though. The three spacial dimensions (length, width, depth) and time.
That’s why the term “4D chess!” is so comical. 4D chess is just a normal game of chess lol.
When people say “4D” they typically mean four spatial dimensions, in addition to time. You’re not being clever, you’re misinterpreting the context.
We’re not even quite sure yet that time is actually different from space. All research seems to suggest they are sides of the same coin.
Depending on how you look at it, considering time a separate dimension at all just seems silly.
Then again, this is just some more context for your context.
Yeah, I’m not arguing that time can be considered a fourth dimension, or the relationship between time and space.
But the comment about 4D being hard to comprehend was referring to the idea of a fourth spatial dimension (as we could comprehend such a thing). Obviously, we don’t have a hard time comprehending time (at least superficially), so the comment about it being “comical” is pedantic and has strong “AKSHUALLY” energy.
Normal chess is 2D + time
Yep, it’s called math.
I was generally surprised at how many people can’t do simple math without a calc, like multiply 7 x 8.
Check mate. Sucker.
Erm…
Meh, close enough.
I haven’t done any long division since highschool, and now that I’d like to, I can’t remember how. 🥺
Good thing search engines exist, eh?
Are you suggesting that I lift a finger to help myself? Why, I never!
The zipper merge.
Impulse control and the general idea of delaying minor pleasures now that will have significant benefits later, or even just not doing things that kinda feel good in the moment but will make you miserable in the near future. As a species we’re pretty terrible at those kinds of judgments.
The meme of the guy poking a stick into his bike wheel in one frame and lying in a crumpled pile in the next is timeless for exactly that reason. Same with shocked Pikachu.
I was going to say long-term thinking. We’re just not wired to consider long-term consequences for the things we do. We continually get duped by promises of lower taxes without considering the damage it will cause for decades to come.
This was my thought too, delayed gratification. Lot’s of people make short term decisions that have negative long-term effects on their mental, physical, or financial health. And humanity does it as well, such as pollution or using fossil fuels when we know it’s going to cause problems in the future.
Exponentials
Breathing without choking on spit
Everybody else is saying things that some humans are too dumb to grasp. I’ll give you an example that virtually all humans are too dumb to grasp.
How are our decisions affected by conflicts of interests? The last time I looked into this, the research in this area said that humans virtually always underestimate the effect that a conflict of interests has on them, by a lot. Many people don’t even see the conflict of interests. People who recognize the conflict of interests believe that because they are aware of the conflict of interests, they can mitigate the effects completely. They are wrong.
Humans get entangled by conflicts of interests just like dogs get entangled by their leashes. Just like dogs, many times, humans don’t realize that they’re caught. Just like dogs, even if you show a human the problem, they cannot understand. But even worse than dogs getting tangled by their leashes, humans believe they can understand what to do when they’re caught up, but it turns out that they’re wrong.
