Not a systematic theory about persuasive communications, this approach is a general framework within which research was conducted. The Yale researchers did not specify levels of importance among the factors of a persuasive message; they emphasized analyzing the aspects of attitude change over comparing them.
Lysenko's theory rejected Mendelian inheritance and the concept of the "gene"; it departed from Darwinian evolutionary theory by rejecting natural selection, viewing that concept as being incompatible with Marxist ideology. [46] Biodynamic agriculture – method of organic farming that treats farms as unified and individual organisms.
A typical example is sharecropping, which has been regarded as economically inefficient [4] or "second-best". [5] However, its persistence throughout the ages has challenged this premise, [6] leading others to conclude that it is efficient, thus credible and functional. [7] That credibility has been confirmed in other studies.
The idea that credibility, and in turn verisimilitude, rested on the reader's sense of the world encountered opposition because of the dilemma it created: every reader and every person does not have the same knowledge of the world. This kind of theory suggests that the novel consisted of distinct parts.
