Many classical-liberal theorists, such as Hayek, have argued that market economies are a spontaneous order, "a more efficient allocation of societal resources than any design could achieve." They claim this spontaneous order (referred to as the extended order in Hayek's "The Fatal Conceit") is superior to any order a human mind can design due to the specifics of the information required. Centralized statistical data, they suppose, cannot convey this information because the statistics are created by abstracting away from the particulars of the situation.
