The life of each ethnic group takes place in relatively the same conditions of existence, which quite naturally gives rise to members of the ethnic community's views on the same subject, common criteria, and similar behaviours. Thus, the surrounding human world has a certain elements of uniformity that typify human behaviour, that is, subordinate to the norms developed and accepted in the community. Stereotypes dictate both the form and content of actions. Stereotyped behaviour doesn't need the motivation. The most powerful argument in favour of this mode of action is a reference to the law of their ancestors. The present study focuses on studying the stereotypical behaviour of the Russian peasant, reflected in folk superstitions. The authors analyzed the sources that precisely recorded standards of behaviour established historically, and came to the several conclusions. Constant monitoring of the environment allowed the farmer to form behavioural patterns under risk and uncertainty of farming. People's signs based on the concept of cyclicity of time and events. An important condition governing the behaviour of the farmers, was the observation of celestial bodies, phase of the moon. Large number of texts will focused on the biological "indicators" – plants, animals. Much more superstitions are advisory in nature than prohibitory. In our work we use the terms “signs” and “omens” interchangeably.
