Consumer behaviour starts with needs and wants, follows a decision process, varies with involvement, depends on perception, is often emotion-led, shows loss aversion, uses mental shortcuts, is shaped by culture and society, expresses identity, responds to perceived risk, produces post-purchase doubt, follows an adoption pattern for new products, varies in price sensitivity and is increasingly digital.
Why will someone queue for hours to buy a new iPhone but spend ten minutes comparing two brands of salt to save ₹2? Consumer behaviour is the study of how people choose, buy, use and get rid of products, and it is full of contradictions like that. Marketers who understand those patterns can design products, prices and messages that actually work.
Here are 14 characteristics of consumer behaviour, with the research behind several of them. For why it matters to firms, see the importance of consumer behaviour in marketing.
14 Characteristics of Consumer Behaviour
1. It Starts With Needs and Wants
Every purchase begins with a need, from hunger to status. Maslow’s hierarchy is still the most common way to map them.
2. It Is a Process, Not a Moment
Buyers move through need recognition, information search, evaluation, purchase and post-purchase review. For a car this can take months; for a snack, seconds.
3. It Varies With Involvement
High-involvement buys (a house, a phone) get careful research. Low-involvement buys (toothpaste) run on habit and shelf visibility.
4. It Is Shaped by Perception
People react to how they see a product, not to what it objectively is. Packaging, price and brand change perceived quality.
5. Emotion Often Leads, Reason Follows
Many choices are made emotionally and justified rationally afterwards.
6. Losses Hurt More Than Gains Please
Daniel Kahneman and Amos Tversky’s prospect theory (1979) showed people weigh a loss roughly twice as heavily as an equal gain. That is why “do not miss out” offers and free trials that auto-renew work.
7. People Use Mental Shortcuts
Buyers rely on rules of thumb: the best-known brand, the middle-priced option, the item with most reviews.
8. It Is Influenced by Culture and Society
Family, friends, religion, region and social class shape what people buy. Festive buying around Diwali or Eid is a clear example.
9. It Expresses Identity
People buy products that say something about who they are or want to be.
10. It Responds to Perceived Risk
Buyers seek to reduce financial, social or performance risk through brands, warranties, reviews and return policies.
11. It Produces Post-Purchase Doubt
Leon Festinger’s cognitive dissonance theory (1957) explains why buyers seek reassurance after big purchases, and why follow-up messages from brands help.
12. Adoption of New Products Follows a Pattern
Everett Rogers (1962) grouped adopters into innovators (2.5%), early adopters (13.5%), early majority (34%), late majority (34%) and laggards (16%).
13. It Is Shaped by Price Sensitivity
Sensitivity varies by product, income and how visible the price is. Many Indian shoppers check MRP and compare across apps.
14. It Is Increasingly Digital
Reviews, influencer content and comparison across apps now shape most purchase journeys, even for goods bought offline.
