There's an old idea of fairness that when cutting a cake between two people one person cuts and the other picks the piece they want.
This method aligns the interests of both parties, no matter how corruptible and *human* they may be.
I think it's underappreciated how often the US government design has a similar method in its checks and balances: one group can reject an official, but they don't get to choose the replacement.
See, for example, impeachment proceedings.
After all: "This policy of supplying, by opposite and rival interests, the defect of better motives, might be traced through the whole system of human affairs, private as well as public."

@volkris Id argue this tactic garubtees an advantage always to the person selecting their piece.
@freemo which means that the person cutting has every interest to make sure both pieces are the same size!
