Principle: Employees of telemarketing agencies should never do anything that predisposes people to dislike the agencies' clients
Application: If an employee of a telemarketing agency has been told by a person the employee has called that he or she does not want to buy the product of a client of the agency, the employee should not try to talk that person into doing so
People who are already predisposed to dislike the client of a telemarketing agency are more likely to refuse to buy the product of that client than are people who are predisposed to like the client.
