CHAPTER 9
Judgment and Decision Making Based on Low
Effort
CHAPTER SUMMARY
This chapter examines the nature of consumer judgment and decision-making when MAO
(and consequently elaboration) is low. In these situations, consumers are more likely to use
simplified heuristics or decision rules. Consumers use the representativeness and availability
heuristics to make judgments; that is, they base judgments on comparisons to a prototype or
on accessibility of information, respectively.
Sometimes low-effort decisions are made unconsciously, sometimes consciously.
Unconscious decisions may be strongly influenced by environmental cues. Conscious low-
effort decision making can follow a hierarchy of effects in which thinking leads to behaving and
results in feeling; in contrast, the hierarchy of effects for high-effort decision making is typically
thinking-feeling-behaving. For simplicity, consumers making low-effort decisions may satisfice
rather than optimize. They may also devise choice tactics over repeat purchase occasions
through a process similar to operant conditioning. Cognitively based choice tactics include
performance, habit, brand loyalty, price, and normative influence; affective-based choice
tactics include affect referral, brand familiarity, variety seeking, and impulse buying.
CHAPTER LEARNING OBJECTIVES
At the end of this chapter, students will be able to:
1. Identify the types of heuristics that consumers can use to make simple judgments.
2. Explain why marketers need to understand both unconscious and conscious decision-
making processes in low-effort situations.
3. Highlight how consumers learn to apply choice tactics through operant conditioning.
4. Discuss how consumers make thought-based low-effort decisions using performance–
related tactics, habit, brand loyalty, price-related tactics, and normative influences.
5. Describe how consumers make affect-based low-effort decisions using feelings as a
simplifying strategy, brand familiarity, variety seeking, and impulse purchasing.
CHAPTER OUTLINE
I. Low-Effort Judgment Processes
A. The Representativeness Heuristic
1. Categorization process that involves comparisons to the category prototype
2. Marketing Implications
a) Marketers can position their product or service close to a prototype or
exemplar that has positive associations in consumers’ minds.
B. The Availability Heuristic
1. Judgments can be influenced by the ease with which instances of an event can
be brought to mind.
a) More accessible or vivid events are more likely to be recalled and
therefore influence judgment.
2. Word-of-mouth communication leads to the use of the availability heuristic.
3. Tends to ignore base-rate information—the rate at which an event really occurs
for all consumers.
