Final answer:
Riku exemplifies Theory X in assuming his employees are gullible and need to be strictly controlled, which is the opposite of the more empowering Theory Y management style.
Step-by-step explanation:
The question appears to be based on Theories X and Y, which are concepts in management. Theory X describes a management style that assumes most people dislike work, avoid responsibility, and want to be told what to do, achieving goals through rules and punishments. On the contrary, Theory Y suggests people enjoy work, seek responsibility, and prefer to set their own work goals, achieving goals through enticements and rewards.
In the scenario provided, it seems Riku has a dismissive view of his employees, thinking they will believe anything they are told and suggesting they do not think independently. This perception aligns with Theory X, under which managers believe employees are inherently lazy and must be strictly controlled and directed.
