see also, HN, where "the system" that keeps discussion civil focuses entirely on silencing any even slight negatives, and scant attention is paid to the hypersensitivities of the numerous offendees
That's a misperception of the strategy, which isn't about keeping discussion "civil" (we stopped using that word years ago), let alone protecting oversensitive feelings, but rather about staving off the default tendency for internet discussion to turn into lame repetitive shit. We just want an internet forum that stays interesting instead of burning itself to the ground. Scorched earth is not interesting (https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...).
If you know a better way to do that, I'm all ears.
It might be good to first read some past explanations about why the rules are the way they are, so as not to repeat arguments that have already been answered. This subthread gives a worked, detailed example (but it's long): https://news.ycombinator.com/item?id=27161447.
> If you know a better way to do that, I'm all ears.
on /r9k if your message isn't sufficiently unique (judged by bot), it gets deleted and you get a small ban. if you continue, the ban duration increases.
The kind of repetition I'm talking about probably can't be detected by bots, but I'd be delighted to be proven wrong about that. The data is all public so anyone can try!
you were triggered because I mentioned HN and your closeness to HN moderation blinded you to the value of the comment I made.
The article we are discussing is very well summarized by its title, "'Negative intensification bias' and unintended meaning", i.e. I was "on topic".
You are dismissing my comment on a tangent about HN without considering whether the ideas of the article offer any fresh insights that would suggest some alternate goals for managing discussions in general, and whether they apply to HN.
and my comment is being treated with negative intensification bias in reaction to unintended meaning!
I don’t know, to me it seemed the in addition to common courtesy when composing emails it was more perhaps the more important part to also try to be charitable with your interpretation. That whole thing about offense being taken and given, that random strangers didn’t find these emails to be bad, etc.
I feel like I am downvoted for just engaging in an opinionated discussion, but whatever...
The sender there have more power over the result of the exchange, and respondent have a kind of passive role of reacting to the initial stimulus. The common courtesy is one thing known to almost everyone who cares but the sender's passive-agressiveness is hidden from their sight, as is the desire to pressure respondent for some kind of results. The respondents in a calm and charitable state of mind wouldn't normally overreact as much so they are either overworked or anxious which increases the threshold of picking the bad in seemingly common stuff.
It's impossible to change other random people nor alleviate their anxieties or tiredness. So it's on the sender to avoid that which I implied in the TS comment, which in itself is based on the article's examples.
If you read some of the emails that were offensive, it’s understandable why the sender thought they were ok.
I think the problem is that formal is taken for intimidating, and that’s not OK for us to go down that road as a society. This email, for example:
> We acknowledge that our request has a very short timeline and certainly appreciate that you are very busy.
That seems like a very courteous and respectful way to open or close an email to someone when you actually are under pressure and need a response despite the circumstances. I can see why/how the recipient could have been rankled to receive this email, but it’s only passive aggressive if you are expecting it to be, are overly sensitive, or have self esteem issues.
The thing is, sometimes people are in a crunch and do need something from you. That’s not ideal, but it shouldn’t be considered actually outright hostile. IMHO it’s important that it be OK to convey a sense of urgency if you couch your statements with respect and understanding.
> The thing is, sometimes people are in a crunch and do need something from you. That’s not ideal, but it shouldn’t be considered actually outright hostile.
This is true. But another thing is that it's normal for some rushed people to consider it to be an aggressive action. No amount of educational articles will change that, as it stems from a deeper psychological processes, and that makes this specific example almost unavoidable. It's both normal to politely convey urgency and overreact to it, at least internally. Preventing this internal reaction from spilling out is a part of personal emotional control/development which is out of scope of a pragmatic approach.
But other similar things, like harder pressuring and subtle passive-aggression, that cause the same effects and seem innocent for the senders, can be avoided realistically. Otherwise it'd be disingenuous to blame overreaction on the respondent. The sub-tones do matter no matter how polite the message sounds, after all.
I read it completely differently. I see a sentence without punctuation as disinterested, as if they don't even bother to complete the sentence. Maybe acceptable in an IM, but not an email.
Thanks for the response. As SquareWheel also commented, the lack of punctuation seems disinterested or dismissive to me. I suppose my criticism of lack of punctuation is not different than others criticism of its inclusion.
"Ok" is ever more informal than "Ok." The decision whether or not to add the period is of course not always a matter of trying to sound more assertive, but in a three character message that potential cue will necessarily be "scaled up".
I can’t say anything useful about short-form email (I have never been comfortable with it, to be honest), but in IM the termination requirement feels to be already satisfied by the built-in separation between messages—in longer messages, I frequently end up using periods as statement separators rather than terminators. The only reason to use a final period, then, becomes to attach a feeling of additional abruptness or finality to the last sentence, which easily reads as (passive-)aggressive or dismissive. (I’m not saying “offensive” as that’s really more about the perception of the recipient, but these two are about the intent of the originator.)
The conventions for formal messaging and informal messaging are different, and punctuation is a contextual marker for formality. Receiving a reply to a physical letter that read, on company letterhead and with a physical signature
Taxcoder, regarding your proposed changes,
Ok.
Sincerely, Jim Bossman
would be a bit alarming, because it's clear that the letter is a very formal one, but it deliberately omits everything you'd normally put in a letter. If you instead found your proposal mailed back to you with
OK - Jim Bossman
written on the bottom in red pen, you wouldn't be at all worried, although depending on the context you might be insulted by the informality.
I think if a message without punctuation seems sloppy, the situation is formal enough to write a full sentence or paragraph. The combination of little to no feedback and attention to detail is what worries people.
> A period can completely change the meaning of a message.
That's in your mind, unless you think your manager is one of the people who believes in Aggressive Periods. I've read the claim that periods are fraught with meaning many times, and yet I've never actually seen one used that way.
Unless, of course, you meant something more like "OK。。。".
It’s a pretty well documented/discussed aspect of text-based digital communication. Kind of like how text written in all caps is interpreted as “shouting”.
I’m honestly shocked there are HN users who are unaware of the tone implications.
> I’m honestly shocked there are HN users who are unaware of the tone implications.
The tone implications are not an objective fact. They are a quirk of your social group.
As I wrote above, I'm "aware" of the implication in that I have seen it described many times. But it's not an implication that actually exists in any context I am part of.
By contrast, the belief that the ordinary smile emoji U+14642 constitutes an insult rather than a smile is a very real, and therefore more painful and annoying, part of my personal context.
Since my social group does not extend to the NY Times, Washington Post, or any of the authors of any of the links I posted it’s quite clearly not just a “quirk” of my social group. It’s part of a wider shift in how we use language to communicate online.
You can accept it or you can ignore it. Either way, the shift has already happened whether you’ve realized it or not.
My Grandma TYPES LIKE THIS ON FACEBOOK because she insists it shows her excitement. Silly, Grandma...
> You can accept it or you can ignore it. Either way, the shift has already happened whether you’ve realized it or not.
You viewing periods as threatening is not a shift that has happened to me. It's a shift that's happened to you. If I were to "accept it" as you suggest, the only thing that would happen would be that I started misinterpreting my friends and taking offense where none was offered. No part of that is a good idea.
You seem to have a lot of difficulty with the idea that different groups might not communicate in the same way. Do you really believe that everyone using 88 as a fun way to say "bye" is really signaling Nazi sympathies?
Sounds like you not having the shift described by the other guy is a quirk of your social group. Either way, you're both arguing which is more prevalent because it's implied that not 100% of everyone agrees with a social norm. We go with the majority.
I don't think "we go with the majority" just because you prefer the majority's preferences. There are many cultures on the internet and the planet, and they have their own local preferences. If anything, I think it would make sense to go by the Robustness Principle (be conservative in what you send, liberal with what you receive), though not everyone has to accept that, of course.
You're saying the tone implications are a quirk of our social groups. Because of how widespread it is now, I'd argue the lack of tone implications is a quirk of your social groups. You don't have to change how you communicate within your groups, but I hope you'll at least keep this is mind when communicating with people outside those groups.
Interesting. I notice this thread has gradually shifted from being about emails to being about text messaging, and not sure if people noticed, maybe that explains the apparent crossed wires?
It's news to me that full stops are considered rude, but then I don't have a mobile phone. I chat a lot on facebook though, and on MSN before that (with people in many countries, half of them in spanish). Always in...sentences, with full stops. Maybe text chat is a third thing, different to both texting on a phone and email? I don't know. I'd never have suspected a full stop could be rude until reading this thread though!
For myself, I’m from Ohio and I’ve definitely seen language used this way. It is really dependent who you are talking to.
I hang out with a lot of people younger than me, who grew up outside the usual tech circles. They definitely text this way and it’s mostly how I text. People on Hacker News are not the type of people I see talking like this.
not offensive but it can be read as dismissive. sounds good to me or will do seem better, but tbh chat generally sucks and we all just have to learn to not read too much into it.
My last manager would frequently message me "Ack!" after I would bring up some work concern, and until just now I thought he was making the exasperated sound from the Cathy comic strip.
by abbreviating, it seems like you value your own time higher than the other person, like their message is not worth writing a whole word in response. At least, that's how I might feel about it. That and it feels a bit like that sketch in The Office where Kevin drops all his interstitial words for "efficiency" and ends up sounding brain damaged.
Obviously that's not the intent, but as per the article, work-related IMs and emails can heighten negative perception and such.
"In data networking, telecommunications, and computer buses, an acknowledgment (ACK) is a signal that is passed between communicating processes, computers, or devices to signify acknowledgment, or receipt of message, as part of a communications protocol."
No, from my experience, many people consider short reply to a long message a sort of dismissal of their effort, and if it uses slang it seems doubly offensive.
Right. My sense is it’s a dismissive and/or low effort response, especially to any sort of substantive message. But I’m also an anxious person so I’m likely reading into it too much.
My typical reply if I want to quickly acknowledge something is, “Got it. Thank you!”
I think it all depends on how that person usually responds, both in-person, and in written communication. If they are usually chatty and like to over-explain, and sprinkle emojis everywhere, and then, to this one particular message, they respond with just "ok.", then there could be something to it.
However, if they are simply terse and serious most of the time anyway, then they are just being themselves. I would be nice if they were chattier, but it's just their usual personality.
The apple harassment and discrimination claims that related to a manager providing feedback that they thought a presentation was better when it didn't sound like every sentence was a question? Does someone have a link to that. It was pretty recent I think.
The employee was female and was very offended.
The manager may have intended to be helpful.
It looks like this is called tone policing so maybe it is offensive feedback in fact:
The article has examples. It's not about emails "sounding" one way but "actually" not being that way, it's about how different people perceive the same email (the recipient versus outside parties).
> We asked them questions about the email and then asked objective observers to read the same messages. We found people who had received the emails directly rated the messages far more negatively than did the observers.
> Many were outwardly civil and even polite: “We acknowledge that our request has a very short timeline and certainly appreciate that you are very busy.” Or, “Just wondering why no update has been received. No news is good news hopefully!”
Not an office worker and spend much less than 2.5hrs a day reading and responding to emails, but man I don’t get this at all. Maybe people just don’t send me emails that make me feel bad?
Slightly worried I’m constantly offending people like back when I heard that putting a period at the end of a text is the same thing as stabbing them through the neck with a letter opener.
I'm honestly curious when that convention would have seeped into my brain; in checking, I only use periods for multi-sentence texts. And I've practically forgotten what it felt like to be in my 20s. Even my mother's text messages don't end in periods if they're a single sentence. Bizarre how the conventions of a particular communication medium just seep into your brain.
had to laugh at your second point - same for me. i was like, "but periods go after sentences, right?" but now i don't do it
the super weird one is (i live in china currently) that there's a smiley face that is not a smiley face. i always used it. i was hip. i was fitting in. my emoticon game was making progress and then apparently i found out i was doing the equivalent of a reddit /s at the end of all my messages: "that smiley face is a fake smile" how could i know that? it's a yellow smiley face! haha
For me, it was when I moved from the US to Germany. Germans do not use "haha" and the like, but instead emojis. A gratuitous amount.
Either you use them or don't, but you have to realize how you come off to the other person (though admittedly this is less of a problem in Germany to begin with - being direkt and monotone is a virtue here sometimes).
I couldn't care less. Proper grammar can be sacrificed for my own sake (read: laziness) but never for someone's "I'm in the mood of inventing a new rule thus a I state that...".
Here's how I avoid any appearance of a negative tone:
Before I try to correct an error, or ask for anything, I always preface it with "Thanks a lot for <replying, doing something previously, I agree with X, etc...>"
As soon as I noticed that pattern in your comms, I'd discount it. And probably be annoyed by the apparent insincerity, esp. when it would prefix something like "correcting an error".
I have someone who reviews some of my work and will tell me how great my work is then points out all the changes they want made -- it's clear nothing about the work is what they wanted, so the "well done with ..." just feels like being gas-lighted.
In this case, however, I don't think they realise they're doing it.
I think people get upset that they are interacting with an algorithm so to speak. Actually that's not it either, people don't get upset when you start all your letters with "Dear X,". The upsetting thing is the violation of expectations. They thought you spontanously dropped the compliment but you didn't. So the best thing might be to go even further, make it actually obvious that it is formulaic. Just thinking out loud here.
One of the few ideas out of an "employee handbook" that has ever stuck with me is the idea that you should always interpret messages like in this situation - in a professional setting - with vast assumptions that the author isn't trying to offend or upset you. They're just conveying information.
I had never seen anyone use these non-ironically until starting my first job, at which point I assumed every message containing one was passive-aggressive.
I now realize that’s not the case, and use them myself
A few years ago I had a classmate who was rudely terse in his replies to group emails. For instance, if someone asked, "Here is my understanding of blah blah. Is this correct?" This person would reply to all with only the word: "No."
I was surprised to eventually learn that the person behind these weird emails was the friendliest student in the class. Apparently he just wasn't used to emailing. To him, "no" was equivalent to "No, sorry, I don't think that's quite right. I'll try to follow up shortly with a more detailed answer."
What seems to missing from this discussion is fundamental understanding of the mediums used for communication and why you might choose one of the other. We all know about them and yet skirt around the obvious issues with articles like this.
Email generally gets through way faster than a mail letter but is often thought of as being similar. (E)mail gets the text through and no more in general although it can carry pictures and other media. (E)mail is store and forward - it will tolerate delays and eventually arrive.
A phone call/direct conversation is immediate and generally requires more setup cost in time and effort. If the other end is unavailable it wont work at all. Telephone calls may suffer from lag and drop outs. Vocal comms do allow subtle extra information without needing crass emojis etc. Vocal comms are much faster.
There are other factors such as delaying tactics and the like. For example if your work stack is too much, you can simply ignore emails for a while but an incoming call has to be answered or not at that point in time. To be fair, most people understand that non answer means try again later even if you know they could have answered at that time.
Emails can be sat on. Emails can also be fibbed about: "Sorry, my spam filter must have eaten it" or "Your GMail is not sending to my Hotmail".
Email is also often treated as IM. The thing about IM is it is instant by design and is supposed to be a two way chat. smtp isn't.
On balance: for me, I prefer telephony or direct contact than email unless it is impractical or I need a record - even then I still can record a conversation.

QED
The sender there have more power over the result of the exchange, and respondent have a kind of passive role of reacting to the initial stimulus. The common courtesy is one thing known to almost everyone who cares but the sender's passive-agressiveness is hidden from their sight, as is the desire to pressure respondent for some kind of results.

They’re making up names on the spot and we’re nodding our heads as if these are accepted academic phenomenon
A period can completely change the meaning of a message.
One of the managers in my company has the bad habit of making speech to text replies to everything. The end result is:
“Okay, Kayodé.
Thanks.”
Those replies do not help my anxiety disorder. XD
I tend to stay away from one word replies, and if I need to confirm use 10-4 or wilco. Are either of those offensive?
I think if a message without punctuation seems sloppy, the situation is formal enough to write a full sentence or paragraph. The combination of little to no feedback and attention to detail is what worries people.
That's in your mind, unless you think your manager is one of the people who believes in Aggressive Periods. I've read the claim that periods are fraught with meaning many times, and yet I've never actually seen one used that way.
Unless, of course, you meant something more like "OK。。。".
Examples:
“It’s fine!” (It is indeed fine.)
“It’s fine.” (It’s not at all fine.)
“K, thanks” (Got it, thanks)
“K. Thanks.” (Cool. Thanks for nothing.)
“Bye” (See you later)
“Bye.” (Fuck off)
And it's a mistake to assume that your manager must follow the same weird typographical conventions that you do. Odds are he's never heard of them.
I’m honestly shocked there are HN users who are unaware of the tone implications.

Since context is important, let's say this is the message you received after a largely successful demonstration of something you've been working on.
