Week 01
Consumer Behavior ยท Davood Wadi, PhD
People do not buy products. They buy solutions to feelings, problems, and social needs.
Most people think consumer behavior is just shopping.
The purchase at the register is only one second in a long chain.
Before
People spend weeks noticing problems, searching options, and asking friends.
After
After the sale, they use the item, feel happy or regretful, and tell others.
Consumer behavior studies the whole chain: before, during, and after the sale.
Consumption happens in three distinct stages.
Stage 1 is Prepurchase.
The consumer identifies a need and searches for information.
The marketer studies how consumer attitudes form.
Stage 2 is Purchase.
The consumer experiences the store, website, and checkout.
The marketer focuses on packaging, convenience, and store atmosphere.
Stage 3 is Postpurchase.
The consumer uses the product and judges its quality.
The marketer monitors satisfaction, returns, and repeat purchases.
Each moment below belongs to one stage of consumption. Sort them into Prepurchase, Purchase and Postpurchase.
Tap a card, then tap the group it belongs to.
In common speech, people use consumer and customer to mean the same thing.
A customer buys the product.
A consumer uses the product.
A parent buys baby food at the grocery store. The parent is the customer. The baby is the consumer.
Marketers must satisfy both people.
The parent cares about price and nutrition.
The baby cares about taste and texture.
Old economics assumed buyers were perfectly rational.
This model assumed buyers compare all choices, calculate costs, and pick the best option.
Real people have limited time and energy. They use mental shortcuts instead.
Real decisions depend on mood, habits, brand loyalty, and social pressure.
Marketers who treat consumers as cold calculators make bad predictions.
Which of these shoppers fits the old economic model, and which behaves like a real person? Sort them into the two groups.
Tap a card, then tap the group it belongs to.
Need
A need is a basic biological or psychological requirement.
Examples include thirst, hunger, shelter, and belonging. Needs exist before marketing.
Want
A want is a specific way to satisfy that need.
Culture and personality shape wants.
A thirsty person in Montreal wants cold tap water or a soda. A thirsty person in another country might want hot tea.
Marketers do not create basic needs.
Marketers create attractive wants to satisfy existing needs.
One purchase often involves several distinct roles.
The initiator identifies the problem first.
The influencer gives advice and sways the choice.
The buyer pays for the goods.
The user consumes or handles the product.
In a household buying a family car, children influence the choice, but parents buy the vehicle.
A surrogate consumer is an agent who makes buying decisions on behalf of another person.
Personal shoppers, travel agents, and wedding planners have long played this role.
Today, consumers can also delegate this role to AI agents.
The consumer states a goal, such as โfind running shoes under $120.โ
The AI agent searches for options, compares them, and can complete the purchase.
The consumer still uses the product and judges its quality after the sale.
In the language of roles, the AI agent can act as the influencer and the buyer. The consumer remains the user.
Marketers now inform two audiences: the consumer and the AI agent that shops for the consumer.
A student asks an AI agent to buy her hiking boots. Who does each step: the consumer or the AI agent? Sort them into the two groups.
Tap a card, then tap the group it belongs to.
You cannot appeal to everyone with the same message.
Market segmentation divides a big market into smaller groups with shared traits.
Demographics group people by age, gender, income, and education.
Geographics group people by location, city size, and climate.
Psychographics group people by lifestyle, values, and personality.
Behavioral segments group people by how often they buy and how they use the item.
Match each segmentation base with the company that is using it.
Segmentation base
What the company does
Tap a term, then the example it goes with.
Understanding consumers gives firms great power over everyday choices.
Helping
Ethical marketing informs buyers and delivers genuine value.
Manipulating
Manipulative marketing takes unfair advantage of human cognitive weaknesses.
Dark patterns are deceptive website designs that trick shoppers into signing up or spending more.
Dark patterns can also target the AI agents that shop for consumers. A store can make key details, such as the unit price, hard for an agent to find. The agent may then choose a worse option for the consumer.
Regulators and consumers increasingly punish companies that rely on trickery.
Discussion: Think of an item you bought recently that you now regret buying. Which stage of consumption failed you? Did you buy it for a need or an impulsive want?
