Playing on people's inferences (which is different from implying) is a common tactic of the abusive.
Of course, they're all master manipulators, ironically able to lie better than the common people because they can leverage that apparent veneer of truthfulness to deceive even more completely.
Of course when reading over it in the regular fast way of reading through the comments, one might think there is a contradiction, because you said there would be one and so we read it that way. But there really isn't. It's an evasive manoeuvre. Of course they know what you're asking and they specifically do not want to lie and so they choose words you are going to very likely parse in a particular way.
If you think about it, is the "there's a contradiction in the following sentence" way of stating this any different/worse/better than the original? I would argue it isn't. Same level just on opposite sides of the argument.
"Up to 100MBit" in the marketing material as well as the contract. When you complain that you only get 0.5MBit it's basically "buyer beware" because you bought "up to" not "always exactly" 100MBit of connectivity on a shared medium (cable). As long as it's true that the medium actually supports 100MBit there's nothing wrong with this except for it being very deceptive. This kind of thing is all over the place and a lot of people fall for it all the time. And then complain loudly but mostly toothlessly. The internet itself I guess has changed some of this as it's easier for companies to get bad enough publicity out of such things than back in the day but it's doesn't change the underlying facts and mechanics.
You can deceive somebody and still be 100 % truthful.
I've had people argue that answering a question with an intentionally misleading non-sequitur is not lying. e.g. "Did you reaearch your topic?" "I went to the library"; they didn't say when they went to the library nor that they did any research at the library. Or more recently: "Have you been vaccinated?" "Yeah, I've been immunized".
To me such non-answers are clearly a lie because it's not really any different than saying "Yes" and then claiming you were talking about the popular rock band from the 70s for no particular reason. I can see how some people would disagree and I'm not interested in arguing semantics, so I try to avoid the word "lie" in general when "deception" seems less contentious.
Spies seem masters in this, applying it for the good (of whomever they serve).
Bill Clinton's famous 'never had sex with that woman, miss Lewinsky' also comes to mind.
I think it could also be trained (including with humor, even when obviously a lie), as its basically a subset of social engineering or confidence game. When people succesfully lie, they are telling a truth from a certain PoV (one which benefits them). And, it can be a useful trait, too, depending on your where you stand (also a PoV).
Side note: the word lie is indeed not preferred, a better one is deceptive or manipative.
That being said, BPD was hyped in 90s where a lot of women got the diagnosis, while they were underrepresented in autism diagnoses.
No, it's not. Making an utterance with the intent of someone else inferring a particular thing from it is implying that thing.
