 Questions can also be raised about the techniques advertisers use to sell. These questions are similar to the ones asked about advertising. Salespeople are, in a sense, the final advertisers of products to consumers. An early contribution to the ethics of sales is found in Holley (1986), who develops a set of obligations for salespeople derived from the point of market activity, which he says is to efficiently meet people’s needs and wants (cf. Heath 2014). In what is probably the most sophisticated treatment of the subject, Carson (2010) says salespeople have at least the following four pro tanto duties: (1) provide customers with safety warnings and precautions; (2) refrain from lying and deception; (3) fully answer customers’ questions about items; and (4) refrain from steering customers toward purchases that are unsuitable for them, given their stated needs and desires. Carson justifies (1)—(4) by appealing to the golden rule: treat others as you want to be treated. He identifies two other duties that salespeople might have (he is agnostic): (5) do not sell customers products that you (the salesperson) think are unsuitable for them, given their needs and desires, without telling customers why you think this; and (6) do not sell customers poor quality or defective products, without telling them why you think this. For the most part, (1)—(4) ask the salesperson not to harm the customer; (5) and (6) ask the salesperson to help the customer, in particular, help her not to make foolish mistakes. The broader issue is one of disclosure (Holley 1998). How much information we think salespeople are required to share with customers may depend on what kind of relationship we think they should have, e.g., to what extent it is adversarial.
