In the mathematical theory of games, the Penrose square root law, originally formulated by Lionel Penrose, concerns the distribution of the voting power in a voting body consisting of N members. It states that the a priori voting power of any voter, measured by the Penrose–Banzhaf index ψ {\displaystyle \psi } scales like 1 / N {\displaystyle 1/{\sqrt {N}}} .
