It's been said that "A half truth is a whole lie". Remind me to never buy anything from you.
You've actually just made my previous point of telling someone the absolute truth, and yet making them believe a lie.

If you
truly cared for someone, why would you ever lead them to believe that you didn't? Even if you then told them what you
really meant, that's like cutting someone, then offering to bandage the wound.
I was a very good retail salesman back in the 70's and early 80's. In fact, on my very first retail gig, I came on to the team a month or so into a sales contest and barely lost. But my mantra was always, "they are not buying the product. They are buying you.". So trust was a biggie.
However, you are right to a degree, but only to a degree. There was only one customer in all those years that I "intentionally screwed", and it has haunted me to a degree my entire life since then. The first word out of the young couple's mouths was that they didn't trust salesmen. They were a responsible couple and had saved a long time to be able to pay cash for a VCR.
I gained their trust and sold them a Sanyo Beta VCR.
Meanwhile, when wireless remotes came out, we had a ton of top of the line RCA VCRs with wired remotes to dump. I would sell them by pointing out that you never lose the remote, you don't have to worry about batteries going dead and no matter where you point it, it works rock solid.
I was telling this story to my son in law who owns his own very successful company and afterward he looked at me and said, "I did not know wired remotes ever existed. I think I would prefer it to our wireless remotes." i.e. I sold him on wired remotes 40 years later.
But your comment about "a half truth is a whole lie" describes the current mainstream news outlets beautifully. A classic example is the Nick Sandmann case. I saw their reporting, and then I saw the raw video. They intentionally misled, using "partial" information, and paid the price.
This is why I don't trust the press any more. And I mean ALL outlets. I yank out the raw data and ignore the fluff. And sometimes its very difficult to get the raw data.
