Недостоверность слуха в данном случае понимается так, что информация СМИ содержит опровержение и тем самым инокулирует индивидов, то есть делает их невосприимчивыми к слуху. В то же время индивиды, успевшие принять слух, перестают доверять средствам массовой информации и тем самым становятся недоступными для переубеждения. Для данного процесса предложена математическая модель в двух вариантах. Вариант с непрерывным временем позволяет выявить некоторые математические свойства модели. Вариант с дискретным временем более удобен для анализа реальных процессов, так как позволяет оценить параметры модели. Для оценки этих параметров использованы данные о рейтингах основных социально-политических программ российских телеканалов. Приведено несколько сценарных расчетов модели с этими параметрами. Основной вывод состоит в том, что если информация, распространяемая средствами массовой информации, не является вирусной, то есть не пересказывается зрителями своим соседям по социуму, то СМИ оказываются не в состоянии противостоять слухам.

In this case, the unreliability of hearing is understood so that the information of the media contains a refutation and thereby inoculates individuals, that is, makes them immune to hearing. At the same time, individuals who have managed to accept the rumor cease to trust the media and thereby become unavailable for persuasion. For this process, a mathematical model is proposed in two versions. The variant with continuous time reveals some of the mathematical properties of the model. The discrete time option is more convenient for analyzing real processes since it allows one to estimate the parameters of the model. To assess these parameters, data on the ratings of the main socio-political programs of Russian TV channels were used. Several scenario calculations of the model with these parameters are presented. The main conclusion is that if the information disseminated by the media is not viral, that is, it is not retold by viewers to their neighbors in society, then the media are unable to resist rumors.
