80. Ambiguity and a polysemy of any statement as a source of a possible error

From the point of view of the authors of the regulation instructions for the Chernobyl nuclear reactor, personnel had broken their requirements, whereas from the point of view of the personnel, they operated precisely according to its requirements⁵⁷. Regulations required for operators to “muffle the reactor,” from the point of view of the authors this was to be done immediately, but from the point of view of the operators is was to be gradual. Another example is when there is an automatic rescue system in a plane as well as a manual rescue system, and if they are both executed simultaneously, they run into each other and lead to catastrophe (nose-dive and crash of Aeroflot Flight 953 in 1994 in Siberia). It is difficult to reach an unequivocal understanding of terms in cases where we do not have experimental experience, as in global catastrophes.
