Answer:
Richard is using the central route of persuasion.
Explanation:
According to the elaboration likelihood model, there are two fundamental routes to persuasion: peripheral and central. While the peripheral route is driven by immediate impressions, the central route considers all the objective merits of a decision.
For example, if a person wants to buy a car, the central route would make the person consider the car durability or fuel efficiency; on the other hand, a person under the peripheral route could make his decision based on the colour or design.
