Based on the strict definitions of concepts, such as deduction, the deduction rule and the deduction system, the form axiom, the substantive axiom, this article clearly shows the essence of the deductive reasoning, namely “Related attribute and the related restriction relations, which are conveyed in what the main concept of the deduction refers to, must be contained in those conveyed in what the premise proposition refers to”。Then puts forward the theorem “contradiction can not be derived from the strict deduction system”, and gives the proofs.

Interpersonal responsibility is an indigenous Chinese personality construct, which is regarded to have positive social functions. Two studies were designed to explore the relationship among interpersonal responsibility, proposal allocation ratio, and responders’ hostile decisions in an ultimatum game. Study 1 was a scenario study using a hypothetical ultimatum game with a valid sample of 551 high school students. Study 2 was an experimental study which recruited 54 undergraduate students to play the incentivized ultimatum game online. The results of the two studies showed a significantly negative correlation between interpersonal responsibility and responders’ rejection responses only when the proposal allocation ratio was 3:7. In addition, in study 2, interpersonal responsibility had negative effects on responders’ rejection responses under the offer of 3:7, even after controlling for the Big Five personality traits. Taken together, proposal allocation ratio might moderate the effects of interpersonal responsibility on hostile decision-making in the ultimatum game. The social function of interpersonal responsibility might be beyond the Big Five.
