       | analysis instead of going into defensive mode.
       | 
       | Daniel Dennett takes the paradigm further by adding a prequel,
       | which is to clearly articulate the other person's logic and state
       | of mind empathically first, before going into the analysis. Done
       | well, this enhances possibilities for cooperation because it
       | elevates the status of the receiver through respect, even when,
       | or especially when the parties views are not aligned.

           | The commenter's advice is emphasized quite a bit in
           | negotiations books/courses. If you want the other person to
           | listen to you, it really does help if you can summarize his
           | stance _in his voice_ - such that he will say  "This guy gets
           | what I'm trying to say."
           | 
           | Probably the majority of heated discussions I've witnessed is
           | where they are talking past one another, and as a 3rd party
           | observer it's very clear neither side understands where the
           | other party is coming from, and they waste most of the time
           | addressing things the other person isn't saying.
           | 
           | NVC is less explicit about it, but the principle is there:
           | 
           | "So it sounds like you're frustrated because the script takes
           | an hour to run and you believe it can run in 10 minutes, thus
           | saving you some time?"

       | The best advice I can give is to start investing into it early

       | For example, I try to make sure my team understand that I have
       | _always_ team 's best interest in mind, that I am first to admit
       | if I make a mistake and that I am always ready to evaluate my
       | position as new information comes.
       | 
       | It goes really a long way to help in a difficult situation but it
       | also prevents a lot of difficult situations from happening in the
       | first place.
       | 
       | It also tends to make other team members and management to be on
       | your side which may help in a lot of situations (but not always,
       | not with the most stubborn people).

       | In my own life, I have spent many, many years, dealing with some
       | of the most difficult people on Earth. Many, who have yet to
       | learn the tools of nonviolent (as in "Not picking up a chair, and
       | breaking it over your head" nonviolent) feedback.
       | 
       | There's something to be said for trying to confront someone that
       | could break you in two, has severe psych issues, and Bic-pen-ink
       | tattoos. It sort of helps you to focus on outcomes.
       | 
       | In my experience, starting by laying out a platform of common
       | goals and achievements is always a great icebreaker.
       | 
       | i.e.
       | 
       | ME: _" We've really made a lot of progress on the fundraising,
       | but we still have to get the registration packets done, and the
       | catering menus finished, in time for the conference."_
       | 
       | I've found that ignoring personal insults and blamethrowing is
       | useful.
       | 
       | BIG BUTCH: _" Well, you were so busy riding your high horse,
       | trying to impress Cathy, that you never checked on my team."_
       | 
       | ME: _" You're right. I should have checked in to see if you could
       | use help. So here we are, and I need your help to deliver the
       | packets to Joe's committee. How can we get this done?"_
       | 
       | Note how I sidestepped horses and Cathy? She'd probably be
       | crushed that I ignored her, but she was irrelevant to the
       | conversation.
       | 
       | Also, it always helps to give them some authority and "upper
       | hand."
       | 
       | Then, there is the firing conversation:
       | 
       | ME: _" I'm afraid that I can't work with your team, any longer.
       | I've found that I can't be productive in our work. I'll need to
       | find someone else to work with."_
       | 
       | There's really no need for "constructive feedback," since The Die
       | Is Cast. If they want that, I am happy to give it, but the main
       | subject needs to be made clear and unambiguous. The relationship
       | is at an end. The time for negotiations and bargaining is over.
       | 
       | I've learned that "weasel words" can be incredibly self-
       | destructive. They leave the appearance of "gaps" that aren't
       | actually there. They are dishonest, and paint me as a coward;
       | which can be taken as weakness. If the decision has been made,
       | then I can't allow it to be second-guessed or misinterpreted.
       | Plain vernacular is worth its weight in gold.
       | 
       | If I need to have a couple of bruisers with billy clubs
       | available, then I can have them file in quietly, after we're
       | settled.
       | 
       | I think that treating people with _respect_ , at all times, is
       | really, really important. Choosing the venue (like not
       | confronting them in front of others) can go a long way towards
       | helping to reach my goals.
       | 
       | Everyone deserves respect; even those that refuse to give me
       | respect.

       | I think the observation vs evaluation examples are sloppy (yes,

       | 
       | I understand this is not a general assessment of the value of
       | observations over evaluations outside of the framework of NVC.
       | Most of the examples would be perceived - at least by me - as
       | impersonal and dishonest. Voicing observations such as "you were
       | ten minutes late this morning" to someone who's knowingly been
       | late already before could be easily perceived as passive
       | aggressive. Passive aggressivity is, I believe, the most subtly
       | violent form of communication, and it really leads to nothing
       | useful or constructive.
       | 
       | Most of the examples read as passive aggressive to me, because
       | you're renouncing to a very direct evaluation that doesn't
       | require a specific knowledge framework and present instead your
       | interlocutor with an emotionless remark about their actions.

         | 
         | I can see your concern, because it's not clear from the
         | article. It _is_ passive aggressive if you leave it at that.
         | NVC does not recommend leaving at that - you have to state all
         | 3: Observation, Need and Feeling[1] - and the book explicitly
         | calls out what happens if you omit any one. In that sense, your
         | position is in line with the NVC book.
         | 
         | A more complete NVC approach is:
         | 
         | > You were ten minutes late this morning. I was annoyed at
         | having to wait for you and lose productivity. Could you explain
         | why you were late?
         | 
         | And no, I should never assume you _know_ you were late, or how
         | late you were. Because I may well be wrong to begin with (my
         | clock is wrong, got you confused with someone else, etc).
         | Without stating this fact, you would be confused.
         | 
         | Or in this conversation we may discover that your watch was
         | off, and the simple correction is to fix your watch. Or you may
         | know you were 10 minutes late, but you also know that others
         | tend to be 15 minutes late and you may want to bring up with me
         | that I hold them to the same standard as I'm holding you. If
         | any of these is true, the conversation is tougher if I don't
         | mention that you were late by 10 minutes.
         | 
         | > Most of the examples read as passive aggressive to me,
         | because you're renouncing to a very direct evaluation that
         | doesn't require a specific knowledge framework and present
         | instead your interlocutor with an emotionless remark about
         | their actions.
         | 
         | Definitely true if you merely make the observation.
         | 
         |  _Edit_ : Another commenter raised a very good point. One of
         | the benefits is to make the observation (without judgment)
         | clear in your own head. It's quite easy to have your brain
         | quickly jump to "lazy" or "tardy" - particularly for repeat
         | offenders. And if you do that, it becomes equally easy to
         | vocalize it, which would be a very big mistake.
         | 
         | In most cases, there is no good reason to make that judgment.
         | If someone is always late, it's quite fine to fire him because
         | he cannot be on time, without having to portray him as a
         | "tardy" person. You and your business have your needs and he
         | couldn't meet them. _What_ he is need not enter into the
         | discussion or narrative.
         |

           | 
           | Honestly, this sounds even worse to me than just the
           | observation. IMO a good test is "Would I say this to my boss?
           | If not, then probably I shouldn't say it at all.". I would
           | not say this to my boss. Not even close.
           | 
           | How about instead:
           | 
           | "Hey, I noticed you were a little bit late, which is unusual
           | for you. Is everything OK?"
           | 
           | And if the pattern continues:
           | 
           | "Hey, I noticed you were a bit late in the last couple of
           | meetings. I think it is somewhat important to be on time. Is
           | there anything I can do to help you avoid being late next
           | time?"

         | I think some missing context here is that the "observation"
         | phase of an NVC communication:
         | 
         | 1. Is in large part for you, the speaker. It forces you to get
         | clear about what you really know to be true. I'm surprised at
         | how often I'm trying to communicate some reaction I'm having,
         | and it's really hard to even say what triggered it. In the
         | process of figuring that out I get a lot of clarity about hat I
         | was expecting or hoping for, what was missing, what the other
         | person actually did, and just by virtue of the reflection,
         | often some "free" insight into what they might have been
         | thinking.
         | 
         | 2. Is always followed by a feeling, need, or request (or some
         | combo of those). This, I think is the key to making it not
         | passive aggressive. If I start with "I need for you to not be
         | late anymore," it's a bit disorienting in the conversation for
         | the other person. What caused you to say that? Why now?
         | Providing an objective observation as context for the rest of
         | what you say allows both people to be on the same page about
         | what the subject even is. Being late is a bit of a trivial
         | example, but just like making the observation alone leaves a
         | lot of work on the listener to infer what you expect to happen
         | as a result of the observation, making the request alone leaves
         | a lot work on the listener to infer what generated the request
         | in the first place, ie. what you think has been happening, what
         | matters to you, etc.
         | 
         | I think the strongest move is actually: observation, then
         | impact, then request. Like:
         | 
         | > Hey, you were ten minutes late this morning. We had to push
         | back the client meeting because you weren't there, and I'm
         | afraid we looked disorganized and untrustworthy as a result. I
         | need you to be on time from now on.
         | 
         | It's quite direct that way.
         | 
         | Also much like the observation step triggering useful self-
         | reflection, the impact step requires you to know why the
         | request matters to you at all. Like if there was no client
         | meeting, what do you care if the other person was 10 minutes
         | late? Maybe you still care, but you need to reflect enough to
         | actually understand why, so that you can say it.

       | Although I do think it's worthwhile to try to think and
       | communicate as clearly as possible, over the years I've learned
       | in this industry that 90% or more of coworkers and managers are
       | not going to put the same effort into it. You can do everything
       | right and the majority of the time it won't matter. The only
       | thing that (almost) guarantees good relationships with management
       | is to just do whatever they want even when it is leading the
       | company to ruin, never voice your objections, etc.
       | 
       | There is no common goal with most managers because they don't
       | usually care about the success of the company, just their own
       | personal success. And with most coworkers, few want to do things
       | better more than they want to just have an easy ride.
       | 
       | If anyone is aware of an environment where meritocracy exists in
       | this industry I'd love to know about it. Where, where can I find
       | a company that cares about making money by providing value?
       | (Obviously some attention is paid to this to make enough money to
       | keep the company going, but it's second to the higher goal of
       | accumulating their personal status and wealth, and there is
       | misalignment between that and actually delivering value due to
       | usually poor leadership at the top and poor investor oversight.)
       | 
       | Maybe it's all just a consequence of capital concentration. There
       | are plenty of companies that could be out competed but
       | competitors just won't be funded, except if they are run by other
       | connected people who don't have the talent to out compete the
       | existing ones.

         | This is correct but the implication is that a good career means
         | having the courage to accept the risk of poor relationships
         | with management and to be willing to end an unhealthy

         | 
         | That is not my experience. When management asks to do
         | something, it doesn't mean it likes any outcome. I am not
         | calling to oppose any decision, but usually there are ways to
         | express concerns. "High risk" for example is language they may
         | understand. I've found that managers many times more confused
         | and disoriented than you may expect. Sometimes asking questions
         | discovers, that there are missing parts in the plan. But it is
         | not easy, even to start questioning you need to have reputation
         | (ex. guy that make things done). Finding right forum ("small

         | Well, people who put "success of the company" at highest
         | priority usually not become manages. Many times managers are
         | blind, because they have to follow orders (directions). Hearing

         | 
         | My general position: I prefer to warn about potential bad
         | outcome of decision without refusing to follow orders.

       | Ah , non-violent communication, a great tool.
       | 
       | I've copied an excellent summary by @BeetleB
       | 
       | To add to the above:
       | 
       | 1. Observations should be specific, not generic ("you are lazy"
       | vs "you have not accomplished any of the tasks you've been
       | assigned"). They should also be objective - third party witnesses
       | should have consensus. We can agree that you've not accomplished
       | your tasks for the week. We will likely disagree on whether that
       | means you're lazy.
       | 
       | 2. Feelings are internal and should not involve someone else. "I
       | feel cheated" is really just saying "I believe I've been cheated"
       | - it's accurately portraying your inner narrative (which may be
       | OK), but it is not portraying your feelings. Instead, you may
       | feel sad, depressed, upset, nervous, whatever. Another way to
       | think of it: Feelings are always legitimate - they are never
       | wrong. The narrative in your head, though, may well be wrong. If
       | someone can reasonably dispute it (assuming he/she is not a
       | jerk), then it probably was a narrative and not a feeling.
       | 
       | 3. Needs: This, in my experience, is easy for tech people to
       | state. If you think someone cheated you out of money, you
       | probably need things like integrity, honesty, security, etc. If
       | your report at work seems unreliable to you, you probably need
       | consistency, peace of mind, etc.
       | 
       | 4. This is making a request. A request is not a demand or a
       | command (so yes, NVC is not appropriate/relevant in contexts
       | where orders make sense). If the person declines your request and
       | you're upset a fair amount by it, you probably were not sincere
       | in making the requests. And finally, your request should also be
       | precise. Not "Could you rephrase that in a respectful manner",
       | but "Could you rephrase that and address me as Mister instead of
       | Dude?"
       | 
       | A few other tidbits from the book (also in Crucial
       | Conversations): You are not responsible for other's feelings.
       | Relieve yourself of that burden/guilt. However, if you want to
       | take things to the next step and have better relations with
       | people around you, do care about their feelings and use
       | techniques to have them feel better - but out of empathy and not
       | out of responsibility or guilt.
       | 
       | In general, the book is about realizing that you have a choice in
       | most things - even things like whether you want to earn money to
       | feed your kids. Likewise, it's about eliminating the language of
       | obligation from your internal dialogues. This may be offputting
       | to people who have a strong sense of obligation.
       | 
       | The above is likely about 90% of the book. The rest of the book
       | are specific, concrete strategies related to the above.

           | I give money to avoid being a "bad" person. NVC eschews the

           | One thing to say here is that empathy is basically putting

           | you also find room in your heart to forgive them, ie. when
           | you see the way their behavior makes sense from the inside,
           | most of the time there's less blame and more "that makes
           | sense, if I look at it that way."
           | 
           | And I guess you're right that by having a policy of caring
           | about people's feelings and acting on that care, you're
           | "taking responsibility" in a broad sense. But there is a
           | difference between acting out of obligation or coersion vs
           | acting out intrinsic care or even out of even-handed
           | consequentialist reasoning (ie. "what communication will
           | cause the outcome I want?").
           | 
           | There's a lot to say about what that difference is, but--just
           | in terms of outcome--"empathizing" out of obligation almost
           | never works. It's because that obligation is kind of lurking
           | within our motivations and comes through in various ways that

           | going on with the other person. Plus it disrupts
           | communicating that understanding in a way that comes through

           | 
           | If there's unspoken blame and contempt in the interaction,
