I don't think I've ever been exposed to those. No sophisticated negotiation in my line of work, just the usual half-truths, lies, pity-seeking.
I don't like to negotiate at all. When I trust a person, I just see if I can afford and go with it, even if I know that I might get it cheaper. Trustworthy people are so hard to find, so I rather pay a little extra for not negotiating. If I don't know them, I research as much as I can about what I need and pre-set my price. If they go whiny or greedy on me, I seek someone else to do the job.
Life is too short to negotiate 😅
We negotiate almost daily with employees, bosses, retail workers, banks, city council, students and teachers, partners, children, friends and family...it just happens in different ways I guess and doesn't always resemble a negotiation that a person has to win or lose. A discussion requiring compromise is a negotiation and negotiation is simply communication.
That's true, I still try to avoid it whenever I can. I think I'm not bad at it, I just don't like it. I prefer straight-forward deals that create win-win-situations. Just finished the negotiations on my CD, got 9.65%, up from the 8.5% that would've been the easy way - but I know how the little cooperativa-banks here work, so it wasn't much of a negotiation. I just stated what I wanted, dropped all the important key words (compound interest, CD renovation, client retention), and there it was. Last year was still 10%, but there's some pressure on cooperativas to drop the interest rates for loans. Guess they didn't negotiate well, and that's overall good for the economy. Most loans are around 15%-25% here.
