7 7  When it comes to designing a persuasive conversational agent, there are several models that can be used. The general approach is to select the response and rule of replying that is most likely to lead to success.

(Once again, maybe not something we will be able to implement but can try to somehow mimic the idea of).

26 +The article does, however, continue by mentioning that the Wizard approach where the robot is simply controlled by a human in a wizard-like fashion managed to persuade 25/60 users and the conversation agent based on the model only managed 1 out of 10 users. It is necessary to remember that designing a persuasive conversational agent consists out of two important aspects - having the robot follow genera human conversational rules, but also applying persuasiveness tactics. I will attempt to clarify these tactics a bit below.
