Determinants of a Civil Society 3-1 Explain the determinants of a civil society Have you ever stopped to think about the social glue that binds society together? That is, what factors keep people and organizations from running amok and doing harm, and what factors create order in a society like ours? The answer lies in social control, defined as any means used to maintain behavioral norms and regulate conflict. Behavioral norms are standards of proper or acceptable behavior. Social control is part of your life at every level, from your family to your local community, to the nation, to the global civilization. Several modes of social control are important to marketing: Ethics: Ethics are the moral principles or values that generally govern the conduct of an individual or a group. Ethical rules and guidelines, along with customs and traditions, provide principles of right action. Laws: Often, ethical rules and guidelines are codified into law. Laws governments create are then enforced by governmental authority. This process is how the dictum “Thou shall not steal” has become part of formal law throughout the land. Law, however, is not a perfect mechanism for ensuring good corporate and employee behavior. Laws often address only the lowest common denominator of socially acceptable behavior. In other words, just because something is legal does not mean that it is ethical. For example, Texas Pete is a hot sauce sold in grocery stores across the country. The packaging for Texas Pete features a lone star, just as the Texas state flag does, and a cowboy holding a lasso. The packaging, along with the name of the product, seems to indicate that the product is made in the state of Texas, or that it is at least made from ingredients sourced in Texas. Texas Pete, however, is produced by TW Garner Foods Company, a company headquartered in North Carolina, more than 800 miles from Texas. A class action lawsuit was filed against the company for false advertising. The lawsuit claimed that consumers were paying a premium price based on their belief that the product originated in Texas, which has a reputation for spicy food. Texas Pete does not explicitly state that the product is manufactured in Texas and actually lists TW Garner Foods’ North Carolina address on the bottle, but the name of the product and the packaging certainly suggest that it is a genuine Texas-based product and could be misleading to consumers. While this presentation is technically legal, is this ethical? What’s your opinion? Here’s another example: In every state, littering is a problem—and has been for many years. Threats of fines and even jail time are shrugged off as people toss food wrappers, plastic straws and cups, and everything else imaginable out the car window. Many companies are implementing new policies to try and curtail the negative effects of littering. For example, Starbucks in California no longer automatically gives straws and plastic cutlery to customers, but, rather, will only provide these items when customers specifically request them. Nicole Glass Photography/Shutterstock.com Formal and Informal Groups: Businesses, professional organizations (such as the American Marketing Association and the American Medical Association), and clubs (such as Shriners and Ducks Unlimited) all have codes of conduct. These codes prescribe acceptable and desired behaviors for their members. Self-Regulation: Self-regulation involves the voluntary acceptance of standards established by nongovernmental entities, such as the American Association of Advertising Agencies (AAAA) or the National Association of Manufacturers. The AAAA has a self-regulation arm that deals with deceptive advertising. Other associations have regulations relating to child labor, environmental issues, conservation, and a host of other issues. The Media: In an open, democratic society, the media play a key role in informing the public about the actions of individuals and organizations—both good and bad. Laundress, a luxury laundry detergent brand that claims to be better for you and better for the environment, came under fire after issuing a safety notice for almost all of its products. The company released the notice on its social media accounts but provided very little information about the reason for the notice. It was later revealed that the majority of the products the brand manufactured between January 2021 and September 2022 contained heightened levels of bacteria that were causing severe skin rashes and other physical ailments. Many major media outlets, including The New York Times and USA Today, published articles to inform the public of this safety notice and the product recall that eventually followed. An Active Civil Society: An informed and engaged society can help mold individual and corporate ethics, as well as socially responsible behavior. Research reveals that 56 percent of U.S. consumers stop buying from companies they believe are unethical. In the United Kingdom, 53 percent of consumers reported that they would completely stop buying from a brand accused of sourcing from unethical suppliers. manufactured between January 2021 and September 2022 contained heightened levels of bacteria that were causing severe skin rashes and other physical ailments.

Ethical Theories People usually base their individual choice of ethical theory on their life experiences. The following are some of the ethical theories that apply to marketing. Deontology The deontological theory states that people should adhere to their obligations and duties when analyzing an ethical dilemma. This theory means that a person will follow their obligations to another individual or society because upholding one’s duty is considered ethically correct. For instance, a deontologist will always keep their promises to a friend and follow the law. A person who follows this theory will produce very consistent decisions because those decisions will be based on the individual’s set duties. Deontological theory is not necessarily concerned with the welfare of others. For example, suppose a salesperson has decided that it is their ethical duty (and very practical) to always be on time for meetings with clients. Today they are running late. How are they supposed to drive? Is the deontologist supposed to speed, breaking the law to uphold their duty to society, or is the deontologist supposed to arrive at their meeting late, breaking their duty to be on time? This scenario of conflicting obligations does not lead us to a clear, ethically correct resolution, nor does it protect the welfare of others from the deontologist’s decision. Utilitarianism The utilitarian ethical theory is founded on the ability to predict the consequences of an action. To a utilitarian, the choice that yields the greatest benefit to the most people is the ethically correct choice. One benefit of this ethical theory is that the utilitarian can compare similar predicted solutions and use a point system to determine which choice is more beneficial for more people. This point system provides a logical and rational argument for each decision and allows a person to use it on a case-by-case basis. There are two types of utilitarianism: act utilitarianism and rule utilitarianism. Act utilitarianism adheres exactly to the definition of utilitarianism as just described. In act utilitarianism, a person performs the acts that benefit the most people, regardless of personal feelings or societal constraints like laws. Rule utilitarianism, however, considers the law and is concerned with fairness. A rule utilitarian seeks to benefit the most people but through the fairest and most just means available. Therefore, added benefits of rule utilitarianism are that it values justice and doing good at the same time. As is true of all ethical theories, however, both act and rule utilitarianism contain numerous flaws. Inherent in both are the flaws associated with predicting the future. Although people can use their life experiences to attempt to predict outcomes, no human being can be certain that their predictions will come true. This uncertainty can lead to unexpected results, making the utilitarian look unethical as time passes because their choice did not benefit the most people, as they had predicted. Another assumption a utilitarian must make is that they can compare the various types of consequences against each other on a similar scale. However, comparing material gains such as money against intangible gains such as happiness is impossible because their qualities differ so greatly. Casuist The casuist ethical theory compares a current ethical dilemma with examples of similar ethical dilemmas and their outcomes. This theory allows one to determine the severity of the situation and to create the best possible solution according to others’ experiences. Usually, one will find examples that represent the extremes of the situation so that a compromise can be reached to include the wisdom gained from the previous situations. One drawback to this ethical theory is that there may not be a set of similar examples for a given ethical dilemma. Perhaps that which is controversial and ethically questionable is new and unexpected. Along the same line of thinking, this theory assumes that the results of the current ethical dilemma will be similar to the results in the examples. This assumption may not be true and would greatly hinder the effectiveness of applying this ethical theory. Moral Relativism Moral relativism is a belief in time-and-place ethics, that is, the truth of a moral judgment is relative to the judging person or group. According to a moral relativist, for example, stealing is not always wrong—if you are a parent and your child is starving, stealing a loaf of bread is ethically correct. The proper resolution to ethical dilemmas is based on weighing the competing factors at the moment and then deciding to take the lesser of the evils as the resolution. Moral relativists do not believe in absolute rules. Their beliefs center on the pressure of the moment and whether the pressure justifies the action taken. Virtue Ethics Aristotle and Plato taught that solving ethical dilemmas requires training—that individuals solve ethical dilemmas when they develop and nurture a set of virtues. A virtue is a character trait valued as being good. Aristotle taught the importance of cultivating virtue in his students and then having them solve ethical dilemmas using those virtues once they had become an integral part of his students’ being through their virtue training. Some modern philosophers have embraced this notion of virtue and have developed lists of what constitutes a virtuous businessperson. Some common virtues for businesspeople are self-discipline, friendliness, caring, courage, compassion, trust, responsibility, honesty, determination, enthusiasm, and humility. You may see other lists of virtues that are longer or shorter, but here is a good start for core business virtues. 3-3. Ethical Behavior in Business 3-3 Describe ethical behavior in business Depending on which, if any, ethical theory a businessperson has accepted and uses in their daily conduct, the action they take may vary. For example, faced with bribing a foreign official to get a critically needed contract or shutting down a factory and laying off a thousand workers, a person following a deontology strategy would not pay the bribe. Why? A deontologist always follows the law. However, a moral relativist would probably pay the bribe. While the boundaries of what is legal and what is not are often fairly clear (e.g., do not run a red light, do not steal money from a bank, and do not kill anyone), the boundaries of ethical decision making are predicated on which ethical theory one is following. The law typically relies on juries to determine if an act is legal or illegal. Society determines whether an action is ethical or unethical. In 2022, Oracle, an information technology company, was forced to pay $23 million to settle charges of violating the Foreign Corrupt Practices Act (FCPA). The U.S. Department of Justice and the Securities and Exchange Commission (SEC) allege that subsidiaries of the company in India, Turkey, and the United Arab Emirates used discount schemes and sham marketing reimbursements to finance funds that were then used to bribe foreign officials. Michael Egbert, corporate communications VP for Oracle, stated that “The conduct outlined by the SEC is contrary to our core values and clear policies, and if we identify such behavior, we will take appropriate action.” Morals are the rules people develop as a result of cultural values and norms. Culture is a socializing force that dictates what is right and wrong. Moral standards may also reflect the laws and regulations that affect social and economic behavior. Thus, morals can be considered a foundation of ethical behavior. Morals are usually characterized as good or bad. “Good” and “bad” have many different connotations. One such connotation is “effective” and “ineffective.” A good salesperson makes or exceeds the assigned quota. If the salesperson sells a new computer system or an OLED TV to a disadvantaged consumer—knowing full well that the person cannot keep up the monthly payments—is that still a good salesperson? What if the sale enables the salesperson to exceed their quota? “Good” and “bad” can also refer to “conforming” and “deviant” behaviors. A doctor who runs large ads offering discounts on open-heart surgery would be considered bad, or unprofessional, because they are not conforming to the norms of the medical profession. “Good” and “bad” also express the distinction between law-abiding and criminal behavior. And, finally, different religions define “good” and “bad” in markedly different ways. A Muslim who eats pork are considered bad by other Muslims, for example. Religion is just one of the many factors that affect a businessperson’s ethics. Academic researchers have examined how consumers react to the trade-offs between highly competent but less moral service providers and less competent but highly moral service providers. Their study found that consumers valued competence more than morality. In other words, purchasers of services want someone who can do the job right . . . even if that person might be a bit shady. For example, a house-painting company that does excellent work but has had some legal problems in the past would be preferred over a mediocre painting company that has never had complaints or legal problems. 3-3a. Morality and Business Ethics Today’s business ethics consist of a subset of major life values learned since birth. The values businesspeople use to make decisions have been acquired through family, educational, and religious institutions. Ethical values are situation specific and time oriented. Everyone must have an ethical base that applies to conduct in the business world and personal life. One approach to developing a personal set of ethics is to examine the consequences of a particular act. Who is helped or hurt? How long do the consequences last? What actions produce the greatest good for the greatest number of people? A second approach stresses the importance of rules. Rules come in the form of customs, laws, professional standards, and common sense. “Always treat others as you would like to be treated” is an example of a rule. 3-3a.

Ethical Guidelines and Training In recent years, many organizations have become more interested in ethical issues. Yet interest and action are not always the same thing. Although some companies are now appointing a Chief Ethics Officer (sometimes called a Chief Compliance Officer), this role is still not present at many companies. It is very common, however, for companies of various sizes to develop a code of ethics as a guideline to help marketing managers and other employees make better decisions. Creating ethics guidelines has several advantages as follows: A code of ethics helps employees identify what their firm recognizes as acceptable business practices. A code of ethics can be an effective internal control of behavior, which is more desirable than external controls, such as government regulation. A written code helps employees avoid confusion when determining whether their decisions are ethical. The process of formulating the code of ethics facilitates discussion among employees about what is right and wrong and ultimately leads to better decisions. Ethics training is an effective way to help employees put good ethics into practice. The Ethics & Compliance Initiative’s State of Ethics and Compliance in the Workplace Report found that 84 percent of employees who work for a company with a strong ethics and compliance program perceived their organization as having a strong ethical culture. Comparatively, only 13 percent of employees working for an organization classified as having an underdeveloped ethics and compliance program felt that their organization had a strong ethical culture. Strong ethical cultures give employees the appropriate guidance to handle situations involving potential wrongdoing and lead to lower rates of misconduct. Still, simply giving employees a long list of dos and don’ts does not really help employees navigate the gray areas or adapt to a changing world market. In Carson City, Nevada, all governmental lobbyists are required to attend a course on ethics and policy before they can meet with lawmakers. The training outlines exactly how and when lobbyists are allowed to interact with lawmakers and how to report any money they spend. A clear understanding of ethical expectations is essential to an industry like lobbying, where illicit—often illegal—actions are taken to promote individual causes. Because artificial intelligence (AI) is becoming so pervasive in marketing interactions with consumers, it must also be taught about ethical decision making. Already Microsoft, Adobe, and IBM, along with smaller firms and start-ups, are developing ethical guidelines and best practices for their AI use. Type “gymnast” into Google’s image search and the vast majority of the top results are female, as are the results for “nurse.” The term “parents” shows almost exclusively heterosexual couples. The results of these searches are driven by AI, which isn’t explicitly taught to discriminate. Rather, these prejudices are the result of the data submitted to the AI algorithm. “There is increasing concern that algorithms used by modern AI systems produce discriminatory outputs, presumably because they are trained on data in which societal biases are embedded,” notes Madalina Vlasceanu, an Assistant Professor of Psychology at New York University, whose research explores biases in internet search algorithms and the potential impact of these biased search results on society. The Most Ethical Companies Each year, Ethisphere magazine (targeted toward top management and focused on ethical leadership) examines more than 5,000 companies in 30 separate industries, seeking the world’s most ethical companies. It then lists the top 100. The magazine uses a rigorous format to identify true ethical leadership. A few of the selected winners are shown in Table 3.1.

Exam Review Chapters 1, 2, & 3. Chapter 1 The Science of Psychology Behavior: Everything, we do that can be directly observed. Behavioral approach: an approach to psychology emphasizing the scientific study of observable behavioral responses and their environmental determinants. Biological approach: an approach to psychology focusing on the body, especially the brain and nervous system. Case study or case history: an in-depth look at a single individual. Cognitive approach: an approach to psychology emphasizing the mental processes involved in knowing: how we direct our attention, perceive, remember, think, and solve problems. Control group: The participants in an experiment who are as much like the experimental group as possible and who are treated in every way like the experimental group except for a manipulated factor, the independent variable. Correlational research: research that examines the relationships between variables, whose purpose is to examine whether and how two variables change together. Critical thinking: The process of thinking deeply and actively, asking questions, and evaluating the evidence. Dependent variable: The outcome; the factor that can change in an experiment in response to changes in the independent variable. Double-blind experiment: An experimental design in which neither the experimenter nor the participants are aware of which participants are in the experimental group and which are in the control group until the results are calculated. Evolutionary approach: An approach to psychology centered on evolutionary ideas such as adaptation, reproduction, and natural selection as the basis for explaining specific human behaviors. Experiment: A carefully regulated procedure in which the researcher manipulates one or more variables that are believed to influence some other variable. Experimental group: The participants in an experiment who receive the drug or other treatment under study—that is, those who are exposed to the change that the independent variable represents. Functionalism: James’s approach to mental processes, emphasizing the functions and purposes of the mind and behavior in the individual’s adaptation to the environment. Humanistic approach: An approach to psychology emphasizing a person’s positive qualities, the capacity for positive growth, and the freedom to choose any destiny. Hypothesis: A testable prediction that derives logically from a theory. Independent variable: A manipulated experimental factor; the variable that the experimenter changes to see what its effects are. Longitudinal design: A special kind of systematic observation, used by correlational researchers, that involves obtaining measures of the variables of interest in multiple waves over time. Mental processes: The thoughts, feelings, and motives that people experience privately but that cannot be observed directly. Natural selection: Darwin’s principle of an evolutionary process in which organisms that are best adapted to their environment will survive and produce offspring. Naturalistic observation: The observation of behavior in a real-world setting. Placebo: In a drug study, a harmless substance that has no physiological effect, given to participants in a control group so that they are treated identically to the experimental group except for the active agent. Placebo effect: The situation where participants’ expectations, rather than the experimental treatment, produce an experimental outcome. Population: The entire group about which the researcher wants to draw conclusions. Psychoanalysis: techniques involves an analyst unlocking a person's unconscious conflicts by talking with the individual about his or her childhood memories, dreams, thoughts, and feelings. Psychodynamic approach: an approach to psychology emphasizing unconscious thought, the conflict between biological drives (such as the drive for sex) and society’s demands, and early childhood family experiences. Psychology: The scientific study of behavior and mental processes. Sample: The subset of the population chosen by the investigator for study. Sociocultural approach: an approach to psychology that examines the ways in which social and cultural environments influence behavior. Structuralism: Wundt’s approach to discovering the basic elements, or structures, of mental processes. Theory: A broad idea or set of closely related ideas that attempts to explain observations and to make predictions about future observations. Validity: The soundness of the conclusions that a researcher draws from an experiment. In the realm of testing, the extent to which a test measures what it is intended to measure. Variable: Anything that can change. Wilhelm Wundt is most often regarded the "founding father" of modern psychology. He was also the founder of structuralism. William James was the founder of functionalism. J. B. Watson and B. F. Skinner believed that psychology should focus on an organism's visible interactions with the environment—that is, behaviors. Ethical Guidelines developed by the American Psychological Association include: • informed consent. • confidentiality. • deception. • debriefing.

Somatosensory cortex: A region in the cerebral cortex that processes information about body sensations, located at the front of the parietal lobes. Stem cells: Unique primitive cells that have the capacity to develop into most types of human cells. Stress: The responses of individuals to environmental stressors. Stressors: Circumstances and events that threaten individuals and tax their coping abilities and that cause physiological changes to ready the body to handle the assault of stress. Sympathetic nervous system: The part of the autonomic nervous system that arouses the body to mobilize it for action and thus is involved in the experience of stress. Synapses: Tiny spaces between neurons; the gaps between neurons are referred to as synaptic gaps. Temporal lobes: Structures in the cerebral cortex that are located just above the ears and are involved in hearing, language processing, and memory.

Convergence: A binocular cue to depth and distance in which the muscle movements in an individual’s two eyes provide information about how deep and/or far away something is. Depth perception: The ability to perceive objects three-dimensionally. Difference threshold: The degree of difference that must exist between two stimuli before the difference is detected. Feature detectors: Neurons in the brain’s visual system that respond to particular features of a stimulus. Figure-ground relationship: The principle by which we organize the perceptual field into stimuli that stand out (figure) and those that are left over (ground). Frequency theory: Theory on how the inner ear registers the frequency of sound, stating that the perception of a sound’s frequency depends on how often the auditory nerve fires. Gestalt psychology A school of thought interested in how people naturally organize their perceptions according to certain patterns. Inner ear: The part of the ear that includes the oval window, cochlea, and basilar membrane and whose function is to convert sound waves into neural impulses and send them to the brain. Kinesthetic senses: Senses that provide information about movement, posture, and orientation. Middle ear: The part of the ear that channels and amplifies sound through the eardrum, hammer, anvil, and stirrup to the inner ear. Monocular cues: Powerful depth cues available from the image in one eye, either the right or the left. Noise: Irrelevant and competing stimuli—not only sounds but also any distracting stimuli for the senses. Olfactory epithelium: The lining of the roof of the nasal cavity, containing a sheet of receptor cells for smell. Opponent-process theory: Theory stating that cells in the visual system respond to complementary pairs of red-green and blue-yellow colors; a given cell might be excited by red and inhibited by green, whereas another cell might be excited by yellow and inhibited by blue. Optic nerve: The structure at the back of the eye, made up of axons of the ganglion cells, that carries visual information to the brain for further processing. Outer ear: The outermost part of the ear, consisting of the pinna and the external auditory canal. Pain: The sensation that warns an individual of damage to the body. Papillae: Rounded bumps above the tongue’s surface that contain the taste buds, the receptors for taste. parallel processing: The simultaneous distribution of information across different neural pathways. Perception: The process of organizing and interpreting sensory information so that it makes sense. perceptual constancy: The recognition that objects are constant and unchanging even though sensory input about them is changing. perceptual set A predisposition or readiness to perceive something in a particular way. place theory: Theory on how the inner ear registers the frequency of sound, stating that each frequency produces vibrations at a particular spot on the basilar membrane. retina The multilayered light-sensitive surface in the eye that records electromagnetic energy and converts it to neural impulses for processing in the brain. Rods: The receptor cells in the retina that are sensitive to light but not very useful for color vision. selective attention: The act of focusing on a specific aspect of experience while ignoring others. semicircular canals: Three fluid-filled circular tubes in the inner ear containing the sensory receptors that detect head motion caused when an individual tilts or moves the head and/or the body. Sensation: The process of receiving stimulus energies from the external environment and transforming those energies into neural energy. sensory adaptation: A change in the responsiveness of the sensory system based on the average level of surrounding stimulation. sensory receptors: Specialized cells that detect stimulus information and transmit it to sensory (afferent) nerves and the brain. signal detection theory: An approach to perception that focuses on decision making about stimuli in the presence of uncertainty. subliminal perception The detection of information below the level of conscious awareness. Thermoreceptors: Sensory nerve endings under the skin that respond to changes in temperature at or near the skin and provide input to keep the body’s temperature at 98.6 degrees Fahrenheit. top-down processing The operation in sensation and perception, launched by cognitive processing at the brain’s higher levels, that allows the organism to sense what is happening and to apply that framework to information from the world. trichromatic theory: Theory stating that color perception is produced by three types of cone receptors in the retina that are particularly sensitive to different, but overlapping, ranges of wavelengths. vestibular sense: Sense that provides information about balance and movement. visual cortex: Located in the occipital lobe, the part of the cerebral cortex involved in vision. volley principle: Principle addressing limitations of the frequency theory of hearing, stating that a cluster of nerve cells can fire neural impulses in rapid succession, producing a volley of impulses. Weber’s law: The principle that two stimuli must differ by a constant minimum percentage (rather than a constant amount) to be perceived as different.
