That makes sense. I was approaching it from an "all models are wrong, some are useful" perspective though, and it seems to me like the consultant-vs-salesperson analogy might be a useful way of thinking about it.
I’d begin by limiting the number of rounds allowed in the negotiation. I’ve spent the last decade in sales, and the best negotiations are typically the ones in which both parties have a hard deadline and have to get it done quickly.
Agreed. In an ideal world there's no benefit to having more than one round, since all information that's going to be shared can be shared up front. I'm not sure if real life considerations change that.
Salesperson here. Most of us think like consultants. At least those of us who stay in the game for more than two or three years.
