Nail, meet head. It’s the ultimate game played out over and over. Two people are put in a room. One is given a sum of money and told to split it with the other. If the other accepts the offer, they keep the money. If the other rejects the offer, they both get nothing.
You’d think 50/50 would be an easy solution, right? But it seldom plays out that way. Instead, one will ask the other how much more than nothing they’d like.
