I have a special interest in faireness. There’s a technical definition in mechanism design: a mechanism (say for allocating goods) is Fair if all participants derive equal utility from participating. Compare to Efficiency: total utility is maximized (each good went to the person who wanted it most). You get both fairness and efficiency by having the winners pay the losers just enough so that the losers are as happy with the money as the winners are with the booty minus the money. A related mechanism property is envy-freeness: no one would prefer to trade places with anyone else.
Eliezer’s conception of fairness does not account for a whole category of “fairnesses”. Let me put the devil’s shoes.
There are many ways to divide the pie fairly. You may divide it according to the amount of people. In which case each person gets 1/Nth.
But my way is more fair. You should divide it according to the weight of each individual, in which case Big Joe gets more than Tiny Anny.
Agile Carlos stands up and says: No, the fair way is according to metabolic rates.
It is naïve to say that the pie should be divided equally between persons, since the numerical level of personhood is not the factor that best correlates with what food is useful for.
To decide what should a pie be divided according to, we would start to play Reference Class tennis, because it is hard to decide if fairness should be symmetric on the person, the metabolic, or the size level.
So even though arguments will stop Zaire from taking the whole pie, I am still not nearly convinced that it is obvious that 1/Nth is fair.
There’s a technical definition in mechanism design: a mechanism (say for allocating goods) is Fair if all participants derive equal utility from participating.
Could you provide a reference for this? The use of interpersonal comparison of utility here surprises me.
I thought that the usual definition of fairness took into account both what you gain from your participation and what other people gain from your participation.
ETA: Are you referring to the same notion of fairness as in this famous paper by Rabin?
