This article is a good excuse to get rid of outdoor advertising for safety reasons.

I was watching some tours of some very nice metro stations in China and Moscow. I didn't quite understand what was so nice about them until one comment pointed it out: no advertising blasting bright colors into your retinas. Advertising in public spaces needs to be banned. It's visual pollution and it's using publicly funded assets to make tangible profits while the losses are externalised easily because they're not well understood. If profit is all you care about then it's easy to justify turning your house into a brothel.

I'd say the daily "visual clutter" of living in Chinese cities is on par or more than other cities, like Tokyo.

In Shenzhen for example, it's not uncommon to see police wearing flashing sirens on their shoulders as part of their uniform. Motorcyclists share the same road as pedestrians, and with so many delivery app drivers you're always on the lookout to avoid being hit.

On SZ and Beijing metro trains, video ads are projected inside tunnels, matching the speed of the carriage - example: https://youtu.be/sp7KDNKpVhY

Personally I've seen much more advertising on Chinese shopping apps like Taobao, compared to say Amazon. Cluttercore advertising seems to be a deeply rooted culture there.

> In Shenzhen for example, it's not uncommon to see police wearing flashing sirens on their shoulders as part of their uniform. Motorcyclists share the same road as pedestrians, and with so many delivery app drivers you're always on the lookout to avoid being hit.

I don't think this is quite as distracting as semantic-laden graphics like ads. They quite literally pollute the mind as well as the view.

When I was in Tokyo in ‘97 they were already testing these subway displays. The ones I saw just showed fancy test patterns not ads, and were smaller.

Your heart is in the right place, but you negate all of that with either incorrect reasoning, or unnecessary hyperbole.

First, you can make your point without saying "turning your house into a brothel". You and I both know, you said that to elicit an emotion reaction. It is an appeal to moral values, when you could have much rather said - "profit maximizing at all costs is bad, or not well understood".

Second - "publically funded assets to make tangible profits". This is incorrect. Governments do all sorts of things so that private individuals / companies can make profit. For instance, they build roads and bridges and highways to enable commerce. They give our licenses to establish companies. They put up stock exchanges so that shareholders can speculate and make money.

By doing both of these, you have diluted the core of your argument which is "outdoor advertising is visual pollution" and has some "safety concerns".

> They give our licenses to establish companies.

How generous of them to allow us to pay to bypass the barrier they put in place

A company is meaningless without a government and law enforcement. The existence of a barrier is necessary for a company to have practical value as a legal concept.

That's not really true; in places without government, or adaquate aligned government, businesses have been known to form their own police forces and quasi-governments, even navies. Profit is a powerful motivator, if something business needs doesn't exist already they'll create it.

So, they create a government because it’s necessary for the businesses.

It's misleading to claim that companies own their existence to governments, to imply some innate subservience of companies to governments, when companies can and have created governments whenever the need arises.

You're getting the cause and effect wrong. For a company to exist, there needs to be stable structures in place. Foundational things like money, infrastructure, laws, people - "Capital".

There are many examples of companies causing those stable conditions to exist. They even create currencies whenever one doesn't already exist. It doesn't work in only one direction, that's my point.

When it goes the other way, would it be more appropriate to call those gangs, not companies?

> It's misleading to claim that companies own their existence to governments

It's misleading to point to exceptions as the rule.

> companies can and have created governments

If you are referring to a company as "a group of individuals" (vis a vis the dictionary definition), that's outside of this conversation.

>> They give our licenses to establish companies.

The original discussion is about corporations (and smaller business companies) as they exist in the US.

I'm talking about companies as commercial enterprises seeking to profit from doing business. No funny business with esoteric definitions.

You say companies creating governments are the exception because usually governments which are compatible with doing business already exist. And this is in no small part because companies modify their environment to create that set of circumstance in the first place. Sometimes they create governments outright where none previously existed. Most often they do it by lobbying or bribing a government to adopt rules better for doing business. Sometimes they hire private armies to destroy and replace governments which cannot be brought into alignment with the companies.

The colonial trading companies are the most famous examples because of how extreme they were, but there are countless examples throughout history and around the world. Companies forming governments outright, complete with new currencies, was common in the undeveloped American west. Companies hiring mercenary armies to destroy unaligned governments has happened several times in South and Central America.

Companies needing governments are like beavers needing ponds. If none suitable exists, they make one.

> esoteric

The legal concept doesn't feel esoteric to me. In contrast, "companies" creating governments is quite rare in my mind. The historical concept you're referring to was even more of a legal concept. Those companies were individually chartered by their host governments. They might have inflicted something else on their victims, but ... Let's take the East India Company as an example. It might have appeared sovereign at times, but was trivially dissolved by the British Empire.

I suspect the downvotes are mainly due to the lack of something tangible to latch onto for a continuing line of dialog. The "and" in "Yes, and...".

I wish more comments on HN were as well-presented as yours. "By doing both of these, you have diluted the core of your argument which is 'outdoor advertising is visual pollution' and has some 'safety concerns'." -> Indeed. It's difficult for me to find fault with this.

Since childhood I've found billboards to be a very mildly dangerous distraction - increasingly so over the years as they've gotten colored lights, LED screens, animations, etc. And the proliferation of close-quarters digital ads which add audio feel particularly violating to me. When my Uber/Lyft rides have those tablets with unending ads, when gas station pumps insist on bombarding me with harsh noise from a too-small speaker driven too hard, etc.

Pro-tip for the vast majority of gas station pump TV advertising screens that are in service at the moment in the USA - if it has four rectangular buttons (all/mostly unlabeled) next to the screen, the third button down is an unlabeled "Mute" button about 90% of the time. I have not yet found a mute feature on the newest models that are just starting to replace those.

> profit maximizing at all costs is bad, or not well understood

How is it not well understood ? It does not seem very hard to imagine what the consequences would be since it already happens sometimes... Or do you think abuse when scaled up can have unexpected good social consequences ?

I would like to defend that brothel metaphor. You say the goal is to appeal to emotions (brothel bad == advertising bad) but it could be argued that the actual purpose is to be striking: It's unexpected so my brain will notice. To me this is just good storytelling and I didn't feel manipulated. Actually I would feel more manipulated if the metaphor was more discreet.

In Moscow metro my personal bane is the mind-numbing amounts of reverberating noise due to open design of stations with no soundproofing, but yes, there are also advertising screens in both trains and on stations.

In Beijing metro while going from the airport I remember the looping propaganda on LCD screens with caricatures of how the West consists of bad, fat, ugly people who should be hated. It’s been like 10 years since I have been there so I forget the details, but I have some photos from the metro where ads ended up in the shot.

In Shenzhen metro, screens with ads, screens everywhere on eye level. The highlight is when a screen is glitching.

I think whether they also blast audible ads, so that you truly have no escape, depends on the train. In Hong Kong, newer trains do.

People are often misled that because a country is ostensibly in opposition to the west, it is somehow immune to inconveniences and issues we associate with capitalism. All of those places are de facto capitalist, just with higher degrees of corruption and oligarchy, and (despite what propaganda paints) they suffer from all of the same issues, multiplied by lack of care from the authorities.

I don't like marketers or advertising, but I don't understand what you mean by: "Advertising in public spaces". In the US, advertising is always on private property.

...which is obviously designed to be maximally visible from the public space.

Private property visible from a mile away :)

I don't disagree, but how would you propose regulating that? Laws are made with money, so the advertisers win unless we can outspend them. That seems unlikely to me.

Many places have heavily regulated if not outright banned outdoor advertising. Businesses aren't quite as opposed to this as you might expect, since a lot of advertising is done to simply counterbalance the advertising their competitors are doing. If everybody is barred from it, everybody wins.

(Not the marketers). If this sort of logic held, health insurance wouldn't exist. I would love to be proven wrong, but I can't imagine it in U$A.

There are places in the """U$A""" where outdoor advertising is heavily regulated. A handful of states have banned billboards and many more towns have too. The Supreme Court has repeatedly reaffirmed that such bans are constitutional. Advertising companies may piss and shit themselves but pretty much everybody else likes it.

https://en.wikipedia.org/wiki/City_of_Austin_v._Reagan_Natio...

> Austin is one of 350 cities and towns in Texas that enacted bans related to digital billboards along the sides of highways, generally as a long-term effect of the Highway Beautification Act as well as to avoid distractions for drivers along these highways.

Basically, your defeatism isn't supported by the facts.

Advertising into public spaces.

Some of that "private property" is publicly funded (or at least heavily subsidized) infrastructure.

> we can’t read out of the corner of our eyes, no matter how hard we try

This is not quite true. Reading via peripheral vision is a skill, but most people never have the right kind of motivation (and perhaps not the right kind of visual stimulus) to learn it. I know this because I have personally known someone who read exclusively via her peripheral vision.

There's an inherited retinal disease that runs in my family. It's a form of 'cone-rod dystrophy'. Cone-rod dystrophies are diseases where the cones and the rods in the eye eventually stop responding to light. The order of the terms in the naming reflects the typical order of the dystrophy: first the cones (responsible for central vision) go, then the rods (responsible for peripheral vision) go, too. As the cones and rods go bad, this results in loss of visual acuity in central and peripheral vision respectively. (It often causes lots of other, less generic problems, too, such as: blind spots, warping/twisting distortions in the visual field, sometimes flickering artifacts, progressive colorblindness, extreme light sensitivity, and an effective reduction of contrast.)

Between individual cases, there's a lot of variation in how the disease presents. There's no fixed timeline or ordering for the progression (even though the disease's genetic cause has been identified as just a single gene!).

Anyhow, in my late aunt's case, her central vision was useless long before her peripheral vision could give out. So she learned, somehow, to do things like read her smartphone using only her peripheral vision.

We chatted about it once or twice. Onlookers often could not comprehend that she was looking at her phone, since her eyes weren't pointed towards it. She once laughed to me about how someone had asked her 'Why are you sniffing your phone?', while she held it up to her face to read a text message.

My impression is that learning to rely on your peripheral vision in this way is extremely counter-intuitive and difficult to do. (This may have something to do with the mechanisms discussed in TFA.) I wonder if it can even be done at all without first obscuring one's central vision (which I guess you could do artificially with contacts). But evidently it can be done.

It makes me think of a common trick in stargazing that is to look at stars with peripheral vision. Fixating them will make them disappear.

That's because the fovea, the "high resolution" part of the eye we use when focusing on some point is entirely made of cone cells, which give you color vision, but are less sensitive, as opposed to rod cells, that make up most of the peripheral vision. In other words, peripheral vision is better in low light situations.

I discovered this growing up when lying in bed at night. I'd always feel like there was light coming under the door. Then I'd look directly at it and it was pitch black to me. I'd look to the side and the light would seemingly come back. Only years later did I discover the cause you described.

I discovered it similarly in a camping trip when I was a kid. We were walking around in near pitch darkness, and I saw out of the corner of my eye someone walk away from the group and try to hide behind a table or something. When I turned to look I couldn't see anything at all, but if I averted my eyes I could clearly see there was a person moving around crouched behind a table. I can't remember exactly, but I think I wasn't so much seeing them, but rather their movement, and mentally perceiving their silhouette.

I guess it looks sort of like this: https://www.youtube.com/watch?v=M83sF7_fYdM

This was used as a magical trait in Tamora Pierce's Circle of Magic books. One of the characters has the ability to see magic and beings at the edge of her vision ("around" her glasses).

You can also discern some flickering lights in your periphery that are otherwise 'solid' when focused on. Quite annoying.

I guess what the article means is that it's not possible to read with peripheral vision except with very large font size and up close. Was your aunt able to read normal print besides titles? Also, I just tried out of curiosity. I must imagine only her fovea was unusable, and the area just around it (I think it's like 5° off-axis) was still fine, because I think I have pretty good peripheral vision, and I can't make out anything if I intentionally look away from what I'm trying to read. Certainly not on a phone; I have to get it so close to my face that it goes out of focus.

By the way, while it is true that cones are far more densely packed in the fovea, their function is color vision, not central vision. Rods are responsible for motion perception and vision in low-light environments.

> except with very large font size and up close

Yeah, it's hard to say what the determinative factors were because her general visual acuity was so low that she generally needed very large fonts very up close anyway. My mom and my sister and I also have this condition and rely on magnification to varying degrees (and for various reasons— sometimes it's truly about acuity but sometimes larger sizes/bolder fonts are a clumsy way to try to make up for contrast issues). But even those of us with usable central vision generally need large fonts anyway. We're also all, for reasons I think are mostly incidental, naturally myopic (although my mom is no longer nearsighted but farsighted (with low acuity— she's legally blind)).

> Was your aunt able to read normal print besides titles?

No. Even titles, like titles of chapters in a paperback, she could likely only read with magnification. And that's if she could get enough contrast at all. At some point, screens become much easier to read than paper, even at equal sizes.

I should learn more about the precise anatomy because it's interesting, but currently I know more about the subjectivity of it than the mechanics.

> By the way, while it is true that cones are far more densely packed in the fovea, their function is color vision, not central vision. Rods are responsible for motion perception and vision in low-light environments.

There may be other factors in these inherited retinal dystrophies that affect the way their progressions affect field of view, idk. But what I said about which areas are first distorted for cone-rod dystrophies is true, and its reverse is true for rod-cone dystrophies (i.e., retinitis pigmentosa), where people with that condition lose their peripheral vision first and their field of view shrinks from the outside-in. My assumption so far has been that this corresponds to those density differences you mentioned.

> Rods are responsible for motion perception and vision in low-light environments.

I do know that much. :)

One of the features of this illness that's very prevalent for me and my sister right now is extreme light sensitivity, presumably because our eyes rely increasingly on their rods even during the daytime and even in high-light environments. One related I've written about on HN before is how the need for lower total light emission pushes both of us to high-contrast dark themes with the lowest brightness possible. OLED screens are really nice when your rods are in better shape than your cones!

One that I don't think I have is that my colorblindness has been getting worse over time. The last time I took a colorblindness test (administered by a medical professional, at my retinal specialist's office), I could hardly read any of the Ishihara plates at all. (When the doctor came in, he asked me if I only saw in black-and-white, which I found mildly irksome but very amusing. I laughed about it with my family afterwards. I do still see many colors! I just have trouble distinguishing a lot of them, too.) My sister, who was not colorblind at all when she was growing up, is now also colorblind, about as much as me based on her tests.

> Anyhow, in my late aunt's case, her central vision was useless long before her peripheral vision could give out. So she learned, somehow, to do things like read her smartphone using only her peripheral vision.

All I can say is wow.

Humans are incredibly adaptable beings, and she proved it. :)

She'd been through a hell of a lot in her life, but it was always important to her to be pleasant company to the people around her, even in tough times. She was always joking and laughing and telling stories. RIP

Macular degeneration also tends to start in the middle and spread outward. Those people learn the same tricks.

Yep. Before my mom got a correct diagnosis via genetic testing, she was told it was a form of macular degeneration, in part on the basis of those features.

Anecdotally, I noticed that I am much happier and more focused after I clean and declutter my apartment. Clean, flat surfaces, nothing for your brain to process.

Even if it's your own apartment or a house, your brain will constantly have a "thread" firing on all cylinders that tries to parse what you are seeing, non-stop.

If it's things all around you, small details, objects - it will sap your mental energy and you won't even know why.

I feel this as well, and increasingly as I get older. It drives me to simplify my office over and over, or at least add storage elements that can hide clutter. Our dystopian future visions for AR always include an extreme visual chaos of ads — maybe the killer app future for AR is actually to remove extraneous visual noise, much like noise-cancelling headphones.

My girlfriend (who has quite severe ADHD) is exactly like you. Before she can get any work done in our office everything needs to be put away/organized/in it's place or she'll get detracted all the time.

I've noticed that you sometimes host scientific articles discussed on HN, but I don't see you on the author list. Are you mirroring a prepublishing archive, or did you ask authors for special permission or are you just ... sharing it?

Good article!

“Therefore, the detailed visual information you’re getting is from the car in front of you, but the information of interest is outside of your focus.”

This must be one of the reasons you get fatigue and exhaustion during traffic rush hour due to so much visual information.

I noticed intense fatigue wandering Tokyo with my friend who wore magnifying lenses and he could not understand why I was tired. I said it's all the visual stimulation, the signs, the lights, the billboards. I think he was at an advantage with the eyewear, in retrospect.

isn't this the counter example? japanese ads, magazines, documents, websites, are often super visually cluttered. seems counter to the paper to me

if this clutter has negatie affects why has japanese design settled on it?

Its same for TimeSquare still people pay big dollars. Both things can be right, it has negative effect however it is still engaging and effective. It gets the eyeballs

This may just be one small point, but I recall reading that visual clutter signifies a good bargain while lots of white space gives the impression of luxary. Most consumers want a good deal.

I found the opposite personally. Something about the neatness and tidiness let my mind relax and see everything similar to a calm flowing stream. Tokyo is one of the most peaceful cities I've been to, even in the busy areas, and by far the biggest and most populated.

Why does the effect seem to be reversed when out in nature? When I walk in the woods, the visual complexity is arguably much higher than it ever gets in cities, even on a busy highway. But the mental effect seems to be rejuvenating.

I think the fractal patterns match our million year old brains expectations, "stuff" in the article refers to "stuff i need to focus on" (which is everywhere in traffic but mostly in front of you while hiking, and in general, focusing 100 yards away is better for the eyes, and a good walk helps everyone feel better. But this is mostly off topic opinion.

That depends on the nature of the nature. Walking through the African veld is also tiring, because you’re constantly processing threat signals.

It's partly because you're not paying attention. Next time you're out in the woods, try to still hunt for a while. It's a hunting method where you move extremely slowly throughout the woods from cover to cover while watching for animals. You'll find that it takes a lot of mental focus to maintain that level of vigilance.

I feel the opposite, in nature I find the complexity much less. Things are not really moving, they are static. Colors are also very much within similar range. You can be very much in passive mode and enjoy the scenery vs actively trying to process.

According to my Claude chat -

This reality might be like a quantum observation field - cities are full of conscious minds actively observing/measuring/collapsing probability states. Like millions of wave function collapses happening constantly. Nature lets those quantum states breathe, maintaining possibility spaces longer.

Some people thrive in that urban collapse-field - they want that constant measurement and definition. Others need more quantum coherence time, seeking out spaces where consciousness can maintain superposition longer. It's not about visual complexity or stimulation, but about how much conscious observation is forcing reality into defined states.

Cities vs nature isn't just about peace or chaos - it's about the density of consciousness collapse. Like the difference between metal (constant forced collapse) and ambient music (sustained possibility states).

Does this even really mean anything?

One of the ways to load balance the visual information is to scan around the car and briefly look at other things.

Checking mirrors often, looking outside your side window, etc.

Whenever I do those things it helps refresh me quite a bit.

Tangential: staring at a computer screen while having a phone call is distracting. Recommend looking at not-a-screen while talking on-the-phone :)

I have a (IMO bad) habit of looking away from my computer screen (at visual nothingness) when having concentrated discussions over video calls.

For whatever reason it’s just easier to talk when staring out the window at a tree than staring at a face on a screen. I call it a bad habit because it results in accidentally ignoring body language of the person on the other end

100% with phone calls. I typically just slowly pace around around my house when on a phone call without video.

Strange, for me it is obvious how it works.

It goes for locations and activities too but mostly if I look at something it locks and unlocks memories but the thing I'm looking at also becomes part of the active memory.

You have a bunch of stuff hashed against the tree or against a dead gaze or you don't want the person to be part of the thought process.

I forgot the code for the warehouse at a previous job. Typing the wrong one locks the place down. I somewhat panicked but went there anyway, got distracted by something and typed the code without even thinking about it. I also remembered it after walking inside. Took some coffee and it was gone again. I thought, I've been typing that code for years but had never realized I only remember it when looking at the door.

As I reflect and re-read my comment, I think for me it’s simply I’m overloaded.

Looking at a face while talking vs. a tree just increases the mental energy necessary for the call. When you’re chronically exhausted, you start cutting out the little things that seemingly don’t matter (like someone’s body language or facial expression during a call)

Definitely a tangent here. Love the warehouse example though. Similarly, I can’t for the life of me recite my iphone, Apple Watch, or home security alarm PIN codes. It’s just pure muscle memory at this point. When I try to recall the PIN codes in my head, my mind immediately tries to recall the numbers by visualizing my phone (or alarm keypad) and attempting to remember the movement of my fingers in order to deduce what the numbers are.

There’s a saddle point of reading body language that improves communication. But at the point you read micro expressions of dishonesty then it becomes problematic. Nobody likes being called on their bullshit. Detectives get away with it because it’s their job. But none of the suspects like them or want to spend any time around them afterward. They’re effective but they’re also assholes by most cultural standards.

This is why I hate the idea that discussions over coding style are "bike shedding". At least for me they have a very real impact on my productivity and likelihood if introducing bugs.

Is this research not stating the obvious?

As a painter I would differentiate background from foreground by decreasing its saturation, lightness and hue local contrast, softening edges, decreasing neighboring regional contrast and Lessing its average color values in relation to the foreground. Painters have been doing this for hundreds of years.

Isn’t this really just signal-to-noise ratio? The information flow can be any input, be it visual, auditory, tactile, etc. “Clutter” is not a neutral word and leads the reader.

"Visual clutter" is an existing term that's been in use for a while now: https://books.google.com/ngrams/graph?content=%22visual+clut...

Aren't you suggesting that we use the ear term for the eye term instead of the eye term for the ear term? ;)

Signal-to-noise is often used as a modality independent term.

Someone might reference signal-to-noise issues with modern news sources, body language, or a data set of any particular origin.

That seems intuitive. E.g. It is pretty common for people to turn down the radio in their car when they are looking carefully for an address.

I've learned its best to have everyone's camera off in a VOIP call. For many reasons, one cuz if I see faces on screen live it distracts my brain internals enough it impairs my effective IQ in the moment, and adds a kind of biological lag. I don't need any fancy academic studies to "prove" it, because I've lived through directly hundreds of A-vs-B cases over many years.

You lose some things without live faces/cameras, but also gain a lot.

Blog post of mine on it:

Even more compelling reasons to block ads online and in public.

What counts as a "visual stimulus" is unclear to me. Does it mean a static object, as opposed to a blank surface or something that moves, and if it is something that moves, does it move predictably (ex: a rotating fan) or not (ex: a notification).

It is kind of obvious that stimuli like notifications are disruptive, but less so in the other cases.

Some figma boards end up looking like someone vomited a pile of confetti. A prime example of visual clutter for me.

Not sure if this counts, but whenever I'm starting a new project or need to figure out something involved I always start by cleaning up the shop and all surfaces. I was wondering why I did that?

I always looked at my feet while walking as a kid. People sometimes thought I was depressed, but I was just always thinking, and reducing visual noise in service of that.

I wonder if it's the same as looking up and to the left when thinking?

When I started walking for exercise I pulled in a lot of the scenery. As I started trying to walk faster, and over the same old ground, my vision pulled in as I was concentrating on proprioception. On a leisurely jaunt you don't really have to think about what your legs are doing. When you're hauling ass it begins to matter if your left foot is landing a little different from your right, and how big that heave in the sidewalk is ten feet in front of you.

Interesting! I dragged this icon onto my desktop to read later.

Oh no!

It's also interesting how your brain processes information in the corner of your eye. It seems to only process the most basic information - not even color.

If I take a red Coke can and place it in the corner of my eye, I can't even tell what color it is. I can tell there's an object there but the color does not come through until I place it slightly more in my direct line on sight.

I was about to post a link about the fact that our retinas themselves can't sense colors in our peripheral vision.

But apparently that's been debunked!

https://www.aop.org.uk/ot/science-and-vision/research/2015/1...

Back in high school a teacher told us this "fact" as well and I remember being very surprised because it did not match my experience at all. Many times have I tested this theory since, e.g. when waiting at a pedestrian traffic light, looking off to the side so that the light is on the very edge of my peripheral vision, seeing if I can perceive it turn green and always being able to. Of course this is not proof that there are no people who can't do this, but I definitely know that I can see color at the edge of my peripheral vision and I've come to assume that this just varies from person to person.

Maybe it's my red/green color blindness that's playing a role.

I figure the OP link and adversarial images (in ML) are special cases of a more general class of tomography problems.

Any research on the effect of visual clutter in UI design/screens?

No wonder why Steve Jobs was so obsessed about focus, he loved not only a clean interface but also wore same type of clothes and lives a minimal lifestyle.

I've always felt like I have more mental clarity whenever I'm out in the fog, the heavier the better - maybe this is why.

Take Amazon's web site for instance....

Been yelled at one too many times for being bad at finding things when trying to find something amidst clutter.

I try my best, and it’s like…I just can’t see it without a lot of effort and more time than you’d think.

This is a minor technical detail of a well known obvious fact. Research, but news.

I wonder if this is relevant to tech workers. Does a second monitor - if not used as a productivity boost, but rather a neutral convenience - hinder your capability to focus on tasks? Should we turn it off to properly focus?

I have suspected this might be the case for a while, but I'm not aware that it is obvious.

I don't know about other people, but I seem to be able to focus more with visual and auditory noise. Something to do with "stochastic resonance"?

A quick search yields:

> Beneficial effects of noise on higher cognition have recently attracted attention. Hypothesizing an involvement of the mesolimbic dopamine system and its functional interactions with cortical areas, the current study aimed to demonstrate a facilitation of dopamine-dependent attentional and mnemonic functions by externally applying white noise in five behavioral experiments.

> ..These results suggest that white noise has no general effect on cognitive functions.

Differential effects of white noise in cognitive and perceptual tasks https://pmc.ncbi.nlm.nih.gov/articles/PMC4630540/

> Perceptual decision-making relies on the gradual accumulation of noisy sensory evidence. It is often assumed that such decisions are degraded by adding noise to a stimulus, or to the neural systems involved in the decision making process itself. But it has been suggested that adding an optimal amount of noise can, under appropriate conditions, enhance the quality of subthreshold signals in nonlinear systems, a phenomenon known as stochastic resonance.

Stochastic resonance enhances the rate of evidence accumulation during combined brain stimulation and perceptual decision-making https://pmc.ncbi.nlm.nih.gov/articles/PMC6066257/

I went from two screens back to one with a tiling window manager.

What I was finding, was each tab/window/screen swap was a chance to lose focus. In practice I do lose focus a lot if I'm switching between screens.

I don't have the same issue with tiles, and I can also setup workspaces to act a bit like focus rooms. I do a lot of little things to retain focus, another one is removing the mouse from my workflow as much as possible as it feels kind of like taking your hands off the wheel to fiddle with the car stereo. You switch mode, and that can disrupt focus.

I have a friend with 4 monitors. I've set at his desk and the feeling is very similar to a tanning bed.

I don't know that he actually needs those monitors, he seems to end up watching e-sports during his work day, though it hasn't affected his career as far as I know. But then he's well above average so even coasting he's doing more than most.

I really have trouble justifying more than two, unless I'm working on a project with DevOps responsibilities.

There are several windows you need and 'losing' one is more problematic for some people than others.

You need to write code. You need to test the code you just wrote. You need source material for writing new code (docs, bug dbs, stack overflow), and you need windows for any background tasks you're responsible for.

Since source material and testing tend not to overlap, one monitor for both usually works out pretty well. A third monitor, oriented it portrait mode, can usually accommodate enough windows to monitor logs or grafana dashboards. Giving over a spare monitor to it improves the gestalt and increases the odds that you will look at it on an interval that your boss approves of. With a wider (taller when rotated) monitor you can fit 2 dashboards with a little room left over to see the rate of new logs - when things are scrolling too fast or too slow that can indicate a problem with the system before it shows on the graphs.

With a big enough primary monitor, I could do with just 2 (and would have to - my 2nd monitor already hangs off the end of my desk). But at 32" I don't feel I have the space to lose it. Also the 2nd monitor has my only video camera.

Oh I totally should have mentioned, I went from two 24"@ 1080p each to a single 34" at QHD as they call it. So a significant real-estate increase was required to manage one monitor.

I don't use it like two monitors in one. Usually my code editor is two thirds of the screen wide, application I am testing is one third,then terminal windows are across the whole bottom of the screen at about a quarter of the bottom of the screen.

So you are right you do tend to need those things in easy view, and I have achieved that but slightly differently to a multi-monitor setup.

I've noticed that I get very distracted by motion in my peripheral vision, but not by static images. So I can use a second monitor for things like documentation, but not something like Slack that shows new messages, animated gifs/emojis, etc.

I've also configured my text editor to be very "static": when I type, the only things that can happen are the cursor moves, or text is inserted. I have to manually trigger things like the autocompletion popup, LSP checks, or highlighting the symbol under the cursor.

This reminds me of some of the early linting tools that emerged around the time ES5 / node.js was blowing up. I found the defaults to be insanely distracting, giving me warnings about unused variables etc as I was still typing the code (of course it's unused, I just defined it!)

GitHub Copilot is similar, defaulting to provide suggestions to finish your LOC whenever you stop typing. While the AI tools can be very useful, the benefit is lost if I can't focus on what I'm writing.

That's one of the reasons I use Vim. It does absolutely nothing without an input and has nothing unnecessary on the screen. Unfortunately pretty much all modern editors and IDEs aim for the exact opposite, the last time I tried VS Code it even had a button floating above the code for some git related stuff.

So far I haven't seen a piece of software that tries to do everything under the sun while also being enjoyable to use.

Sending this to my partner next time I ask them to clean up.

Another indictment of "transparent" UI (as if we even needed one).

That opposite of what Einstein said
