  This paper presents the research of the influence of cognitive, behavioral,
representational factors on the susceptibility of the participants in social
networks to misinformation, as well as on the activity of the nodes in this
regard. The importance of this research consists of method of blocking the
propaganda. This is very important because when people involuntarily acquire
information some of them experience an undesired change in their social
attitude. Such phenomena typically lead towards the information warfare. A
model was developed during this research for calculating the level of
misinformation of the social network participant (network node) based on the
model of iterative learning process.
