CONSUMER BEHAVIOR:
THE PSYCHOLOGY OF MARKETING
Introduction
The study of consumers helps firms and organizations improve their marketing strategies by understanding issues such as how
The psychology of how consumers think, feel, reason, and select between different alternatives (e.g., brands, products, and retailers);
The psychology of how the consumer is influenced by his or her environment (e.g., culture, family, signs, media);
The behavior of consumers while shopping or making other marketing decisions;
Limitations in consumer knowledge or information processing abilities influence decisions and marketing outcome;
How consumer motivation and decision strategies differ between products that differ in their level of importance or interest that they entail for the consumer; and
How marketers can adapt and improve their marketing campaigns and marketing strategies to more effectively reach the consumer.
One "official" definition of consumer behavior is "The study of individuals, groups, or organizations and the processes they use to select, secure, use, and dispose of products, services, experiences, or ideas to satisfy needs and the impacts that these processes have on the consumer and society." Although it is not necessary to memorize this definition, it brings up some useful points:
Behavior occurs either for the individual, or in the context of a group (e.g., friends influence what kinds of clothes a person wears) or an organization (people on the job make decisions as to which products the firm should use).
Consumer behavior involves the use and disposal of products as well as the study of how they are purchased. Product use is often of great interest to the marketer, because this may influence how a product is best positioned or how we can encourage increased consumption. Since many environmental problems result from product disposal (e.g., motor oil being sent into sewage systems to save the recycling fee, or garbage piling up at landfills) this is also an area of interest.
Consumer behavior involves services and ideas as well as tangible products.
The impact of consumer behavior on society is also of relevance. For example, aggressive marketing of high fat foods, or aggressive marketing of easy credit, may have serious repercussions for the national health and economy.
There are four main applications of consumer behavior:
The most obvious is for marketing strategy—i.e., for making better marketing campaigns. For example, by understanding that consumers are more receptive to food advertising when they are hungry, we learn to schedule snack advertisements late in the afternoon. By understanding that new products are usually initially adopted by a few consumers and only spread later, and then only gradually, to the rest of the population, we learn that (1) companies that introduce new products must be well financed so that they can stay afloat until their products become a commercial success and (2) it is important to please initial customers, since they will in turn influence many subsequent customers’ brand choices.
Social marketing involves getting ideas across to consumers rather than selling something. Marty Fishbein, a marketing professor, went on sabbatical to work for the Centers for Disease Control trying to reduce the incidence of transmission of diseases through illegal drug use. The best solution, obviously, would be if we could get illegal drug users to stop. This, however, was deemed to be infeasible. It was also determined that the practice of sharing needles was too ingrained in the drug culture to be stopped. As a result, using knowledge of consumer attitudes, Dr. Fishbein created a campaign that encouraged the cleaning of needles in bleach before sharing them, a goal that was believed to be more realistic.
As a final benefit, studying consumer behavior should make us better consumers. Common sense suggests, for example, that if you buy a 64 liquid ounce bottle of laundry detergent, you should pay less per ounce than if you bought two 32 ounce bottles. In practice, however, you often pay a size premium by buying the larger quantity. In other words, in this case, knowing this fact will sensitize you to the need to check the unit cost labels to determine if you are really getting a bargain.
There are several units in the market that can be analyzed. Our main thrust in this course is the consumer. However, we will also need to analyze our own firm’s strengths and weaknesses and those of competing firms. Suppose, for example, that we make a product aimed at older consumers, a growing segment. A competing firm that targets babies, a shrinking market, is likely to consider repositioning toward our market. To assess a competing firm’s potential threat, we need to examine its assets (e.g., technology, patents, market knowledge, awareness of its brands) against pressures it faces from the market. Finally, we need to assess conditions (the marketing environment). For example, although we may have developed a product that offers great appeal for consumers, a recession may cut demand dramatically.
Consumer Research Methods
Market research is often needed to ensure that we produce what customers really want and not what we think they want.
Primary vs. secondary research methods. There are two main approaches to marketing. Secondary research involves using information that others have already put together. For example, if you are thinking about starting a business making clothes for tall people, you don’t need to question people about how tall they are to find out how many tall people exist—that information has already been published by the U.S. Government. Primary research, in contrast, is research that you design and conduct yourself. For example, you may need to find out whether consumers would prefer that your soft drinks be sweater or tarter.
Research will often help us reduce risks associated with a new product, but it cannot take the risk away entirely. It is also important to ascertain whether the research has been complete. For example, Coca Cola did a great deal of research prior to releasing the New Coke, and consumers seemed to prefer the taste. However, consumers were not prepared to have this drink replace traditional Coke.
Secondary Methods. For more information about secondary market research tools and issues, please see my handout.
Primary Methods. Several tools are available to the market researcher—e.g., mail questionnaires, phone surveys, observation, and focus groups. Please see my handout for advantages and disadvantages of each. The below flow chart suggests appropriate choices for different types of information needs.

Surveys are useful for getting a great deal of specific information. Surveys can contain open-ended questions (e.g., “In which city and state were you born? ____________”) or closed-ended, where the respondent is asked to select answers from a brief list (e.g., “__Male ___ Female.” Open ended questions have the advantage that the respondent is not limited to the options listed, and that the respondent is not being influenced by seeing a list of responses. However, open-ended questions are often skipped by respondents, and coding them can be quite a challenge. In general, for surveys to yield meaningful responses, sample sizes of over 100 are usually required because precision is essential. For example, if a market share of twenty percent would result in a loss while thirty percent would be profitable, a confidence interval of 20-35% is too wide to be useful.
Surveys come in several different forms. Mail surveys are relatively inexpensive, but response rates are typically quite low—typically from 5-20%. Phone-surveys get somewhat higher response rates, but not many questions can be asked because many answer options have to be repeated and few people are willing to stay on the phone for more than five minutes. Mall intercepts are a convenient way to reach consumers, but respondents may be reluctant to discuss anything sensitive face-to-face with an interviewer.
Surveys, as any kind of research, are vulnerable to bias. The wording of a question can influence the outcome a great deal. For example, more people answered no to the question “Should speeches against democracy be allowed?” than answered yes to “Should speeches against democracy be forbidden?” For face-to-face interviews, interviewer bias is a danger, too. Interviewer bias occurs when the interviewer influences the way the respondent answers. For example, unconsciously an interviewer that works for the firm manufacturing the product in question may smile a little when something good is being said about the product and frown a little when something negative is being said. The respondent may catch on and say something more positive than his or her real opinion. Finally, a response bias may occur—if only part of the sample responds to a survey, the respondents’ answers may not be representative of the population.
Focus groups are useful when the marketer wants to launch a new product or modify an existing one. A focus group usually involves having some 8-12 people come together in a room to discuss their consumption preferences and experiences. The group is usually led by a moderator, who will start out talking broadly about topics related broadly to the product without mentioning the product itself. For example, a focus group aimed at sugar-free cookies might first address consumers’ snacking preferences, only gradually moving toward the specific product of sugar-free cookies. By not mentioning the product up front, we avoid biasing the participants into thinking only in terms of the specific product brought out. Thus, instead of having consumers think primarily in terms of what might be good or bad about the product, we can ask them to discu
