Also, STP’s use of coercive techniques (e.g. ratchet effect, labor camps, etc.), which are argued to be inherent to STP, on the one hand ensured the system's survival and on the other hand resulted in the distorted information that made effective planning challenging if not impossible.[17] And lastly these scholars argue that the semantic limitations of language made it impossible for STP planners to communicate their desires to enterprises in sufficient detail for planning to fully direct economic outcomes.[18] Enterprises themselves under STP still made a variety of economic decisions autonomously.
