jdw64•1h ago
I feel like people only look at the form and ignore the substance of the content. Honestly, as long as the content itself is well written and the em-dash is used correctly, I don't think it really matters.

When I first learned about em-dashes, I was told they were a mark of sophisticated, intellectual writing. But now people say they sound like AI. Is that really a bad thing?

It's strange to see sophistication become low-class just because AI uses it. It makes me think that form is really about who the author is, not the form itself.

In that sense, I'm not sure what it even means to be 'human-like.' Being human-like just feels like an illusion that people who want to believe in it keep insisting on

sarreph•1h ago
I too find it a pity that the em-dash has been co-opted by AI. I use a double-hyphen ("--", the old school way of writing it), but fear that this will also become used by AI seeking a higher form of 'sophistication' as you put it.

We're experiencing broad scale changes in the sentiment of style in written English. I don't know what the best approach to take here is necessarily, but the more I see language evolving over time (especially over the past two decades) I think I'd prefer to shift my habits in line with whatever the "modern standard" is in order to avoid falling into pitfalls, i.e. being accused of being an AI writer.

1718627440•48m ago
> ("--", the old school way of writing it)

The old school of writing it in digital documents. Typesetting predates and is not limited to digital documents.

sarreph•25m ago
Good point, but I think it's a little more complex than that.

To my knowledge (and what I meant by "old school"), it was common to type a "--" dash on typewriters[0] because most of them lacked en- and em-dashes, which are obviously not digital documentation devices.

But yes, typesetters of old (old, old school!) had myriad glyph blocks available to them for pressing!

1718627440•12m ago
On a typewriter you can write symbols overlapping, so if you write '--' it becomes '–'.
Telemakhos•27m ago
The double-hyphen is by no means "old school": it's a kludge for twentieth-century systems like typewriters and word processors that did not have em dashes or an easy way to insert them. The very names "em dash" and "en dash" should illustrate their age: they go back to the fifteenth century, and "em" and "en" were standard printing widths in moveable type. People who write CSS still recognize em as a width.

The idea that a double-hyphen is "old school" is on par with the false notion that double-spacing between sentences is a product of the typewriter; one need only look at a typeset book from before the twentieth century to see the truth, or look at a decent image of the Declaration of Independence or other hand-written document from prior centuries to see the extra space left between sentences.

Many of the changes we see in written English style are the product of ignorance of the past beyond two generations or so. Avoiding em-dashes to keep up with the latest anti-AI fad is just reacting mindlessly to the stimulus of popular ignorance instead of deliberately situating one's style in the history of writing conventions.

nephihaha•1h ago
The em-dash-as-AI trope is nothing new. (Apart from the fact that MS Word etc convert them automatically.)

If I post some information, then I have had people accusing me of cribbing it off Wikipedia. When I have translated from some languages, people assume I'm using Google. Even though in one case, the language in question wasn't even available on Google Translate. (I went and checked.)

ssivark•54m ago
> people only look at the form and ignore the substance of the content.

This is largely because most people are incapable of thinking critically and evaluating substance. So they regress to indirect markers of good writing, and the whole thing becomes a game of signaling.

The rot is so deep, many popular resources on writing focus more on style and presentation than focusing on the substance of writing. And even when best-intentioned, all this does is make poor writing a bit more palatable by giving it a veneer of polish.

brazzy•40m ago
> This is largely because most people are incapable of thinking critically and evaluating substance.

No, with AI it's because it's MUCH faster than evaluating substance, and fast ways to weed out AI slop are desparately needed, since it can be produced so quickly.

brazzy•43m ago
The problem is that the substancelessness of AI writing nowadays tends to be subtle and well-hidden (but huge). Focusing on superficial "tells" is basically an attempt of a quick, cheap defense against the imbalance of human effort, where someone can spend a few dollars and a few minutes and e.g. generate dozens of PRs that would take many hours of real human effort to process and fix the deeper shortcomings of.
dxdm•37m ago
As of recently, there is a strong correlation between use of em-dashes and a verbose, bloated style of writing that uses many words to not quite get to multiple repeated points. Not well written, in other words.

The combination of both I usually find in text generated for me by LLM, and so far, it serves as a good signal for density of information and, inversely, not-quite-right ideas and their connections. (That's not to say it's pervasive, but below the surface, the quality of LLM text as a medium is often not great.)

There may be well-written text of non-trivial length generated by LLMs, but so far I haven't knowingly encountered any, with or without em-dashes. Human editing remains very necessary.

I agree they are inappropriate to use in formal writing. For stuff like blogs and chatting online though, they're fine.

I really don't get liking em dashes. Just use two sentences or modify your original one. Both options are clearer like 90% of the time.

Same. It is really annoying to write something and have someone say, “just so you know, em dashes makes it obvious it was written by AI.” You know how else uses em dashes? People who know how to write.
thewoodsman•41m ago
So... fuck 'em? Hit 'em with a: "You're absolutely right — em dashes are a common signifier of AI" and go about your business. Anyone creating on the internet[1] is running laps around the class of losers who run from post to post dropping useless comments.

[1]: I'd even go so far as to extend that "anyone" to: "anyone creating, even with AI assistance!"

II2II•23m ago
> It is really annoying to write something and have someone say (...)

It's worse than that. What they are saying is the equivalent to saying that knowing how to do something properly, and having the attention to detail to do so, makes it obvious it was written by AI. It sounds like a prelude to human incompetence, to ensuring that AI products are better than human ones.

About the only semi-convincing argument that I've heard is that AI over uses these tells. But let's face reality here: a lot of people griping about AI generated or AI assisted writing are not looking at over use. Plus a lot of people tend to over use the said tells while they learn how to use them properly.

koolala•52m ago
Test: 'There is no greater joy in life than typing a sentence, realising it needs a clarification, a caveat, an addendum, but in the same sentence, not a new one, and, guess what, the comma is right there for you. You want to package things neatly together, and the comma lets you do exactly this. Commas make writing feel like you are assembling lego bricks.'

I like using commas for spacing though em dashes do the same thing and avoid the run-on police?

url00•46m ago
It's a bit like 2 space indention versus 4 or 8 space. I find the em-dash example pretty compelling because visually relaxes my eye more than commas do — similar to how prefer at least 4 space indention over 2.

(Unrelated: The alt-code for em-dash on Windows is Alt+0151. I just typed my first manual em-dash wow exciting.)

thfuran•36m ago
I think offsetting the em dash with spaces is contrary to almost every style guide.
jachee•5m ago
Chicago does it one way and AP does it the other.

I definitely prefer it un-spaced, though, personally.

pohl•45m ago
Your first sentence is a perfect example of why emdashes need to exist. The comma is overloaded, since it can be used both as a list separator and for parenthetical asides. But that first sentence starts using them as a list separator, and then inserts a parenthetical aside into the list. Emdash wins this test.
john_strinlai•50m ago
i typically enjoy a good profanity-laden rant, but something about this particular one feels very forced. this sentence, for example: "[...] What if someone points one out in my writing?”. Bitch, please.". i cant really put my finger on why, but it almost feels like the author wrote their rant, then came back afterwards with a quota of fuck/shit/bitch they wanted to meet, placing them wherever they could.

in any case, i mostly agree with the author that ai has co-opted too many things to be concerned about it anymore. i remember being linked a list of "1,000 words not to use" because ai used them a lot (e.g. "delve", "absolutely", etc.) and the venn diagram with the 1,000 most common english words was practically a circle. you would be unintelligible if you rigorously avoided them all. now i just write without care of my ai-similarity score.

jimbokun•47m ago
It smacks of “Hitler also lived…(some innocuous thing).”
neuroticnews25•38m ago
>you would be unintelligible if you rigorously avoided them all

You could write naturally and then let an LLM translate avoiding the 1000 words, with verification harness or maybe a custom sampler.

moron4hire•50m ago
It's interesting that an article extoling the virtues of the em-dash isn't using them correctly. They don't get spaces around them.
etempleton•47m ago
I have seen this more and more and I don’t understand it.
douglee650•7m ago
I am personally a fan of space padded em-dash. Visually, semantically, it makes sense on all modern planes. There's an argument for line-break parsing.

Of course I recommend do-not-adopt, think Roman-cart-wheel-axle-width reasons.

Forgeties79•45m ago
That’s not entirely true. Some formats yes. In this case they’re using it correctly https://www.merriam-webster.com/grammar/em-dash-en-dash-how-...

It's a stylistic choice. Here's an analysis, complete with a link back to an old HN discussion:

ubitaco•47m ago
I didn't know that AP style recommended spaces either side of the em dash. Here in the UK we generally use en dashes instead, and I thought em dashes always had no spaces. Apparently the wire machines that AP sent their news out by in olden times couldn't always do en dashes.
WillAdams•47m ago
One of the more memorable and influential library finds for me was an article in _Advertising Age_ which enumerated all of the special characters which should be set so as to accurately communicate, so in addition to en and em dashes it noted:

- − (minus symbol) for use in math equations or to indicate a negative

- I believe it also noted that there were two forms for the hyphen, normal and discretionary

- × (multiplication symbol) for use in dimensions and when actually indicating multiplication

- ′ and ″ (single and double primes) for use when indicating feet and inches, or minutes and seconds

- it also made explicit the difference between º (ordinal o) and ° (degree symbol) and noted when to make use of the other ordinals

- … while available as a special character, it is often better to construct this using suitably sized non-breaking spaces

- © ® ™ ℠ ℗ (copyright and so forth) to indicate such legal constructs as appropriate

- the various spaces en and em space, non-breaking flex space, &c.

I _think_ I still have a photocopy somewhere, but really should find a copy of the actual magazine....

The far more egregious and reprehensible thing is that many books now are published using quite pedestrian typing of the near equivalents from the keyboard as opposed to actually typing the correct signs.

I wrote a bit on this at:

https://tug.org/texshowcase/onetype.pdf

(note that it intended to be printed, folded, cut in the center, then re-folded so as to make a "hot dog" booklet: https://www.makingbooks.com/hotdog.shtml )

jonhohle•28m ago
If you’re on a Mac or iOS, it’s extremely easy to use the global text substitution to replace three periods (..., v...) with ellipsis (…, ⋮), and other symbols ((c), (r ), ^o, etc.) with their Unicode equivalent (©, ®, °, etc.).

If I'm writing something, typically I want to share my thoughts with other people and get their feedback. It won't work if they dismiss my writing because of some superficial stylistic choice, without even trying to engage with the ideas that I'm trying to express.

adamtaylor_13•39m ago

I only ever see them with an AP-style spacing before and after.

ryukoposting•37m ago
This post is so self-consciously dependent on inserting em dashes everywhere that it kinda supports its own counterargument. If you're going to make a case for em dashes enabling more fluid writing and more distinctive voice, then you ought to actually use them that way.
st_goliath•34m ago
> ...on Mac, for example, it’s simply Option + Shift + Hyphen.

Fedora with XFCE here, but last I checked on Windows, it worked exactly the same over there: With a Chinese IME installed, tap shift to switch input language, shift+hyphen produces a double em-dash: ——, likewise, shift+6 a double elipsis: ……

You encounter those a lot in simple, machine translated Chinese, along with literal translations of "not X but Y", "not just ... but also" and similar sentence constructs that are common in Chinese. I suspect that's how a disproportionate amount of that ended up in training material in the first place.

cma256•33m ago
I did not know option + shift + hyphen produced an em dash. I've always used a double hyphen as a stand in -- as I did just now. LLMs don't do it and I haven't been accused yet. Though, more likely, I'm not popular enough for people to notice!

The overemphasis by critics on punctuation and "this not that" is tiring. I don't really know how to describe LLM writing but it has the same qualities as flat soda. Some authors you feel as though you fall through their work with little effort; unable to stop until gravity slams you into their conclusion. LLM writing can feel like an uphill hike to a sewage treatment plant. That is, its easy to convince yourself to stop at any time. There's a positive quality to that. I hope AI labs don't find a way to remove it.

I've used dashes in typeset works ever since I learnt how to do them in (La)TeX (---). You don't usually put spaces around them, though.

There are actually four different "dash" type things in TeX: a hyphen, an en dash (for ranges like "10--20 pages"), em dash (---), and the minus symbol ($-$).

swe_dima•22m ago
I also love them - makes spotting AI written content easier. People debated implementing complex algorithms how to watermark AI content - but luckily AI just settled on it by itself.

vitorsr•16m ago
Nothing wrong with CMOS/APA/MLA dashes, I quite like them but usage in LLM prose has ruined it for me. AP dashes are weird, too much horizontal spacing, looks horrible and can really erode typographic color sometimes. "International" Oxford/Cambridge spaced dashes is nicest.

The funny thing is at both extremes, either none or indiscriminate use of dashes like in TFA, is a canary of "human writing".

People (including comments here) often attribute LLM use to prevalence in training data but it is probably far less common in the wild than we are led to believe, the more likely scenario is that whatever text-to-text normalization tools used ended up inserting whatever their idiosyncratic typographic styles were.

douglee650•11m ago
Author failed to explain the dash universe and their semantic assignments.

- em dash: adjoining thought (Hey, so — <declaration>)

- en dash: expresses a range (1–100)

- dash: compounds word-parts (Sarbanes-Oxley)

I'd also like to see more concise philosophy around em v. ellipsis, "limerance" is poetic (and ironically antithetical … and what of parens?). In short, em is communication and ellipsis is prosaic.

I offer this feedback as a humorously offended fan of all sidecar prose pre-AI era.

Finally, I'd love to hear from this author regarding modern use of period in modern comunication, with canonical use-case of bulleted list as example.

Yeah. They also use em dashes to repeat a word with emphasis, something that is done much better with parentheses and italics.

I just thought of the most annoying blog in the world. Individual spacing between words, depending on how thoughtful you want the pause to be. And by "individual" I mean a different floating point number denoted amount of em each. em > em-dashes. Or put differently, em dashes em-dashes.

WillAdams•15m ago
The big reason for manually constructing an ellipsis is to ensure consistent spacing for the 3 and 4 dot forms --- some typefaces will include both, but may not fit well if the type specs have the text set tight or loose.

My apologies, should I have typed \thinspace.\thinspace.\thinspace.\thinspace.?
