I'd say it's technically a lie: an intentional misleading. Paltering is its close cousin.

[–] CultLeader4Hire@lemmy.world 3 points 20 hours ago

The intent matters. Did you omit something on purpose to serve your own agenda/narrative or did you omit something for some other reason.

If you’re omitting something to serve yourself it’s a lie.

Depends. Intentionally omitting information in order to mislead? That's a lie. Simply not mentioning something? Or not mentioning it because it's embarrassing for you or someone else, because you didn't think it was relevant, or because it's not their business or not your business to share? Not really a lie. Not in the same way anyway.

[–] VanRayInd@lemmy.world 3 points 1 day ago (3 children)

Disagree

All lies are deceptions, but not all deceptions are lies

Lies are specific acts that are done, not acting is in itself not an act

Conservation of energy cannot be called an expenditure of energy

When people call something a "lie by omission" it's an attempt to shift the blame wholly to the other person rather than deal with the fact that part of the blame belongs to themselves

My silence was not a lie; you guessed about reality, and I just didn't correct you

You can still use it as a basis for future distrust and you can still use it as a reason to cut off or minimize future encounters

But it is not and should not be considered a malicious action against you as you would a lie

[–] CultLeader4Hire@lemmy.world 3 points 20 hours ago

The his just feels like mental gymnastics to me

[–] mlc894@lemmy.world 2 points 1 day ago

You can absolutely fail to disabuse people of incorrect notions for malicious reasons.

[–] bhamlin@lemmy.world 2 points 1 day ago

I would disagree that omission is not malicious; the intent of the omitter can be any reason. Perhaps not malicious in every case, but it could be as ill-meaning as any lie.

[–] cattywampas@lemmy.world 53 points 2 days ago (1 children)

A lie is based on intent. If you're purposely intending to mislead someone, whether by omitting information or by outright stating false information, then it's a lie.

It really depends on context.

[–] Paragone@lemmy.world -1 points 21 hours ago

yin-lies & yang-lies are on the same spectrum, but at different ends of it.

It isn't a binary/dichotomy.

[–] agamemnonymous@sh.itjust.works 17 points 2 days ago (1 children)

Disagree. It's deceptive, but not a lie. A lie is a deliberately false statement, which omission cannot be.

[–] Cethin@lemmy.zip 0 points 1 day ago* (last edited 1 day ago) (1 children)

That's not totally true. Usually a lie by omission is implying something, and that something isn't true. It is deliberately instilling a sense of false knowledge. You didn't specifically say it, but you still conveyed it. It's still a lie.

Saying something sarcastic is not the same as saying it non-sarcastically, for example. What is conveyed is what's important, not what is said.

[–] agamemnonymous@sh.itjust.works 5 points 1 day ago (1 children)

It is deception, it is not a lie. Not all deception is lying.

[–] VanRayInd@lemmy.world 2 points 1 day ago

I like this, it helps a lot

All lies are deceptions, but not all deceptions are lies

My silence was not a lie; you guessed about reality, and I just didn't correct you

[–] SarahValentine@lemmy.blahaj.zone 28 points 2 days ago* (last edited 2 days ago) (5 children)

I wouldn't consider it in a vacuum. I also look at intent and consequences. Did they omit info to gain advantage over others, or were they refusing to tell a Nazi where they hid the jews? Did their choice lead to a better outcome for everyone, or did it cause chaos and disrupt lives needlessly?

Everyone going "duh it's still a lie" - calling someone a liar carries a specific connotation which I don't think applies in all cases of so-called "lies". To me, a lie carries with it not just an intentional falsehood but an accusation or an accusable misdeed. I wouldn't call someone a liar because they hid jews from nazis.

[–] Korhaka@sopuli.xyz 27 points 2 days ago

Pretty sure not telling the nazi is still a lie. But an example of when it is ethical to lie.

[–] SaltSong@startrek.website 11 points 2 days ago

You are either answering the wrong question, or are defining a lie based on some criteria I don't recognize.

Telling a Nazi there are no Jews in my basement is a lie. The only way it's not a lie is if there are, in fact, no Jews in my basement. But it is not wrong to lie to a Nazi.

[–] charokol@lemmy.world 10 points 2 days ago

A lie is still a lie, even if it’s told to a Nazi or if there’s an otherwise good outcome

[–] chahn.chris@piefed.social 4 points 2 days ago (2 children)

Your point highlights the fact that lies are a tool. The intentional omission is a lie.

Judgment about the tool’s use is subjective.

Everyone uses this tool. Calling someone a liar is either calling them a human or it means you’re saying they use the tool more than they should which is yet another subjective judgment.

Ooh I like that perspective.

[–] YoFrodo@lemmy.world 24 points 2 days ago (1 children)

Omission can be a lie as long as the intent is to deceive. Thats an important element to making something a lie

[–] amorpheus@lemmy.world 1 points 1 day ago (1 children)

I run into this with my wife because we put different importance on different information, and I tend to go for succinct rather than take an hour to get something across.

[–] CultLeader4Hire@lemmy.world 3 points 20 hours ago

I think the issue with this situation is often one person assuming they know what’s important and what’s not instead of letting the other person decide for themselves once they’re given the full info, it’s why omissions are often considered lies.

[–] gigastasio@sh.itjust.works 15 points 2 days ago (2 children)

If Jean-Luc Picard says it’s so, it’s so.

[–] cattywampas@lemmy.world 6 points 2 days ago* (last edited 2 days ago)

Completely serious - I often use WWJLPD to inform a decision I have to make.

[–] Asafum@lemmy.world 3 points 2 days ago

Jean-Luc Piucard demands you make it so

[–] determinist@kbin.earth 10 points 2 days ago

the crucial element of a lie is intention to decieve, either by ommission or commission

[–] Cytobit@piefed.social 6 points 2 days ago

I think omission can be used for misleading/deception, but that it's distinct from a lie.

[–] WongKaKui@piefed.ca 5 points 2 days ago (1 children)

Reminds me of Wheel of Time

Something like "shall speak no word that which is not true" is one of the 3 oaths... but they can still deceive without technically lying...

[–] SpikesOtherDog@ani.social 2 points 2 days ago

Your dress is green.

[–] Kommeavsted@lemmy.dbzer0.com 5 points 2 days ago

If the person lying by omission has the intent of causing the recipient to have false understanding (e.g. to provide basis for a choice) then it's at least as dishonest as a blatant lie.

If they omit information because they think it's irrelevant then it's just ignorance or negligence. Dishonest in the sense that it's not forthright.

Neither lies nor omission are inherently unethical without some basis for the relation between the two people being honesty/loyalty.

[–] chicken@lemmy.dbzer0.com 3 points 2 days ago (1 children)

I think it depends on the context. If it's like a close friend and the deception screws you over and was an unexpected betrayal, then it's basically a lie. If there's some reason someone might suck at a job and they don't mention it in the interview and were not asked, that's different because it's an adversarial situation and looking out for yourself means not showing all your cards, and everyone should understand that it's like that.

No, that would be deceit. Similar, but not the same. You can deceive someone by lying. Lying is an act of deceit.

[–] yesman@lemmy.world 3 points 2 days ago (2 children)

The core of dishonesty is disrespect for others and the truth. That's the core issue. Focusing on the method of prevarication is academic.

[–] yermaw@sh.itjust.works 1 points 1 day ago* (last edited 1 day ago)

I think we need better/more descriptive words for lying and deception.

When I tell my child to stay still for the injection because it wont be very sore and they'll hardly feel it, its not out of disrespect or malice. It is a fucking straight-up lie though I remember getting them when I was a kid.

Edit : for the most part I agree with you, but i think better language could help. Lying to sell a timeshare and lying to get a kid to take their medicine are basically the same thing even though theyre very different.

[–] Nemo@slrpnk.net 1 points 2 days ago

I'm not sure how I feel about your answer, but I appreciate it as a perspective and am glad you shared it.

[–] RBWells@lemmy.world 2 points 2 days ago

If it's on purpose to deceive, I guess.

[–] Deestan@lemmy.world 4 points 2 days ago

Yes.

And lie by suggestion and implication is also a lie.

[–] dohpaz42@lemmy.world 3 points 2 days ago (1 children)

Are you sure you’re not really asking if lying is good or bad? To me that’s an important distinction that should be addressed.

My kids used to believe in Santa and the Tooth Fairy. I perpetuated those lies because it was fun for everyone, and the boys enjoyed it. Now they’re older and know better, and they understand both sides. They were not hurt or upset.

But if I know my friend’s wife is cheating on him, and I don’t say anything to him, then obviously that’s bad and my friend would be devastated even more to find out I withheld such important information.

We often conflate “not telling lies” with “all lies are bad”, and that’s not always true.

[–] Cherry@piefed.social 2 points 2 days ago

I’m an adult and I believe in Santa so when mine asked I could confidently answer Yes.

Call me silly but I’m happy. I believe

[–] northernlights@lemmy.today 2 points 2 days ago (1 children)

Yes, that's why it's called that

agree.

but context matters.

[–] 87Six@lemmy.zip 2 points 2 days ago

Not sure I'd call it a lie according to these definitions...

A lie is an assertion that is believed to be false

a false statement made with deliberate intent to deceive; an intentional untruth

We don't need to call it a lie to ackowledge it still carries the same moral burden, judgement and implications.

I'd call it deception.

[–] Hackworth@piefed.ca 2 points 2 days ago (1 children)

How about a lie of omission to myself?

[–] Reygle@lemmy.world 2 points 2 days ago (2 children)

You can omit things from yourself? I'm not sure if I should be jealous or afraid.

No. Otherwise everyone lies constantly by not telling everyone everything they are aware of at all times. Granted I met some people that would be pretty honesty by that metric. And everyone wants to get away from them.
