//The point has already been made, that if you wish to truly be honest, it is not enough to speak the truth.
I generally don't tell people I'm an atheist (I describe my beliefs without using any common labels). Why? I know that if I say the words "I am an atheist," that they will hear the following concepts:
- I positively believe there is no God
- I cannot be persuaded by evidence any more than most believers can be persuaded by evidence, ie, I have a kind of faith in my atheism
- I wish to distance myself from members of religious tribes
As I said, the point has already been made; If I know that they will hear those false ideas when I say a certain phrase, how can I say I am honest in speaking it, knowing that I will cause them to have false beliefs? Hence the saying, if you wish to protect yourself, speak the truth. If you wish to be honest, speak so that truth will be heard.
Many a politician convincingly lies with truths by saying things that they know will be interpreted in a certain positive (and false) way, but which they can always defend as having been intended to convey some other meaning.

The New
There is a counterpart to this insight, come to me as I've begun to pay more attention to the flow of implicit social communication. If speaking the truth in a way you know will deceive is a lie, then perhaps telling a lie in a way that you know will communicate a true concept is not a lie.
I've relaxed my standards of truth-telling as I've come to understand this. "You're the best" and "You can do this" statements have been opened to me, no qualifiers needed. If I know that everyone in a group has to say "I have XYZ qualification," but I also know that no one actually believes anybody when they say it, I can comfortably recite those words, knowing that I'm not actually leading anybody to believe false things, and thus, am not being dishonest.
Politicians use this method, too, and I think I'm more or less okay with it. You see, we have a certain problem that arises from intellectual inequality. There are certain truths which literally cannot be spoken to some people. If someone has an IQ of 85, you literally cannot tell them the truth about a great number of things (or they cannot receive it). And there are a great many more people who have the raw potential to understand certain difficult truths, but whom you cannot reasonably tell these truths (they'd have to want to learn, put in effort, receive extensive teaching, etc).
What if some of these truths are pertinent to policy? What do you do, say a bunch of phrases that are "true" in a way you will interpret them, but which will only be heard as...
As what? What do people hear when you explain concepts they cannot understand? If I had to guess, very often they interpret this as an attack on their social standing, as an attempt by the speaker to establish themselves as a figure of superior ability, to whom they should defer. You sound uppity, cold, out-of-touch, maybe nerdy or socially inept.
So, then...if you're socially capable, you don't say those things. You give up. You can't speak the truth, you literally cannot make a great many people hear the real reasons why policy Z is a good idea; they have limited the vocabulary of the dialogue by their ability and willingness to engage.
Your remaining moves are to limit yourself to their vocabulary, or say something outside of that vocabulary, all the nuance of which will evaporate en route to their ears, and which will be heard as a monochromatic "I think I'm better than you."
The details of this dynamic at play go on and on, but for now, I'll just say that this is the kind of thing Scott Adams is referring to when he says that what Trump has said is "emotionally true" even if it "doesn't pass the fact checks" (see dialogue with Sam Harris).
In a world of inequality, you pick your poison. Communicate what truths can be received by your audience, or...be a nerd, and stay out of elections.
Suppose X is the case. When you say "X" your opposite will believe Y, which is wrong. So, even though "X" is the truth, you should not say it.
Your new idea as I understand it: Suppose saying "Z" will let your opposite will believe X. So, even though saying "Z" is, technically, lying, you should say "Z" because the listener will come to have a true believe.
(I'm sorry if I misunderstood you or you think I'm being uncharitable. But even if I misunderstood I think others might misunderstand in a similar way, so I feel justified in responding to the above concept)
First I dislike that approach because it makes things harder for people that could understand, if only people would stop lying to them or prefer to be told the truth along the lines of "study macro economics for two years and you will understand".
Second, that seems to me to be a form of the-end-justifies-the-means that, even though I think of myself as a consequentialist, I'm not 100% comfortable with. I'm open to the idea that sometimes it's okay, and even proper, to say something that's technically untrue, if it results in your audience coming to have a truer world-view. But if this "sometimes" isn't explained or restricted in any way, that's just throwing out the idea that you shouldn't lie.
Some ideas on that:
I think you've hit upon one of the side effects of this approach
All the smart people will interpret your words differently and note them to be straightforwardly false. You can always adjust your speaking to the abilities of the intelligent and interested, and they'll applaud you for it, but you do so at the cost of reaching everybody else
