Monkeys lead most negotiators to underestimate their own relative power and so negotiate too ‘chicken’. And there is a structural reason for this error. – When you look at your own situation you are only too aware of your own monkeys. But the other party may not be aware of these factors.• At the same time, the other guy has problems too – and he isn’t going to tell you about the monkeys on his back as this would only weaken his position. • So you have a distorted view of the power balance. It’s distorted because you have taken account of all your monkeys, but have not allowed for the monkeys he almost certainly has on his back – because you don’t know about those. And the distortion is always in the same direction: it always leads you to underestimate your own power.
