Identify and understand the social factors that affect consumer buying decisions. Social factors include such external influences as reference groups, opinion leaders, and family. Consumers seek out others' opinions for guidance on new products or services and products with image-related attributes or because attribute information is lacking or uninformative.

Consumers may use products or brands to identify with or become a member of a reference group. Opinion leaders are members of reference groups who influence others' purchase decisions. Family members also influence purchase decisions; children tend to shop in similar patterns as their parents.

1. Family members play many different roles in the buying process: initiator, influencer, decision maker, purchaser, and consumer. Identify the person in your family who might play each of these roles in the purchase of a dinner at Pizza Hut, a summer vacation, Froot Loops breakfast cereal, an Abercrombie & Fitch sweater, golf clubs, an Internet service provider, and a new car.
