A bogus argument analogous to the argument in the last section now establishes that the ''average'' magnetization in the Ising model is always zero.
# Every configuration of spins has equal energy to the configuration with all spins flipped.
# So for every configuration with magnetization ''M'' there is a configuration with magnetization −''M'' with equal probability.
