Answer:
Credence attribute
Step-by-step explanation:
Credence attribute refers to situations in which a customer cannot personally evaluate the quality or expertise of a particular person who provides a good or service prior to obtaining it. This means that a person cannot see with his own eyes, before purchase or consumption, whether a person is adequate for the job that he is required to do or the good he is required to produce. Therefore, the customer has to believe in his reputation or his claims of expertise. This is the case with Eric, who is unable to discern whether his surgeon is good or not at what he does.
