Consumer Behavior: Decision Processes, Heuristics, Context, and Post-Choice Evaluation

Comprehensive vocabulary flashcards covering the consumer decision-making cycle, low-effort heuristics, situational choice contexts, cognitive biases, and post-purchase evaluation principles.

Problem Recognition

The initial stage of the consumer decision process that occurs when an individual perceives a gap between their actual state and their ideal state.

Actual State

The consumer's current realistic situation, which can fall due to product depletion, malfunction, or changing needs, thereby triggering problem recognition.

Ideal State

The state or outcome a consumer desires to experience, which can be elevated through marketing, social comparisons, or exposure to superior alternatives.

Habitual / Routine Problem Solving

A low-effort decision-making approach requiring little conscious deliberation, minimal information search, and the repeat selection of familiar products such as toothpaste.

Limited Problem Solving

A mid-level decision-making process involving a moderate degree of involvement, minimal search, and comparison across a small number of attributes or alternatives, such as choosing a restaurant.

Extended Problem Solving

A comprehensive decision process triggered by high involvement, high financial or social risk, and costly consequences, requiring extensive search and careful evaluation across options like automobiles or laptops.

Internal Search

The retrieval of brand names, past experiences, product attributes, and evaluations stored in long-term memory.

External Search

The active acquisition of information from outside entities, such as search engines, retailer websites, user reviews, friends and family, creators, forums, or artificial intelligence assistants.

Consideration Set

The subset of salient brands or potential solutions that come to mind and are deemed worthy of serious evaluation by a consumer.

Search vs. Product Knowledge Relationship

An inverted-U relationship showing that consumers with moderate knowledge search the most, whereas novices lack knowledge on how to search and experts search selectively.

Heuristic

A cognitive shortcut or simple decision rule used to make evaluations quickly while conserving cognitive effort and time.

Satisficing

A decision strategy defined by Simon (1955) and Schwartz (2004) wherein consumers choose an option that is "good enough" to satisfy criteria rather than expending effort to optimize.

Availability Heuristic

The tendency to overestimate the likelihood, frequency, or importance of an event based on how easily specific instances or examples can be retrieved from memory.

Representativeness Heuristic

A cognitive shortcut in which consumers judge the probability of an outcome or category membership based on how closely it resembles an expected prototype or stereotype.

Base Rate Neglect

The cognitive tendency to overweight vivid, salient anecdotes while underweighting objective statistical frequencies and population base rates.

Halo Effect

A cognitive bias in which a general positive impression or a single favorable trait favorably colors assessments of unrelated attributes of a person, product, or brand.

Horns Effect

A cognitive bias where a single negative attribute or poor impression causes an evaluator to assume an entity performs poorly across unrelated characteristics.

Sunk Cost Effect

The tendency to persist in an activity or maintain an investment based on non-recoverable past outlays of money, time, or effort rather than assessing future net benefits.

Confirmation Bias

The cognitive inclination to search for, interpret, prioritize, and recall information in ways that reinforce preexisting attitudes, hypotheses, or beliefs.

Optimism Bias (Self-Positivity)

The belief that adverse events such as accidents, health crises, identity theft, or financial misfortune are significantly less likely to happen to oneself than to others.

Curse of Knowledge

A marketer assumption error where a firm presumes consumers share their insider technical vocabulary and specialized specifications, yielding incomprehensible packaging and advertising.

Spotlight Effect (Egocentric Bias)

The tendency of marketers and brands to overestimate the degree of consumer attention, prominence, and scrutiny placed upon their offerings.

False Consensus Effect

A marketing trap where brand representatives mistakenly project their personal preferences, tastes, and priorities onto prospective customers without inquiring about actual consumer values.

Scarcity Heuristic

A rule of thumb presuming that items difficult to obtain due to limited quantities, restrictive release windows, or exclusive access are inherently more valuable and desirable.

Price as a Quality Cue

A simplifying shortcut where consumers infer superior quality from high monetary costs, frequently applied when evaluating product attributes is difficult or expertise is scarce.

Brand Loyalty

Repeat purchase behavior fueled by a deep, enduring preference and emotional bond with a brand rather than mere convenience or habit.

Status Quo Bias

The tendency to maintain one's default choice or take no action when options are presented, rooted primarily in switching costs and loss aversion rather than brand devotion.

Fundamental Attribution Error

The tendency to overemphasize internal personal traits and dispositions when explaining other people's actions while underestimating the impact of situational context.

Self-Serving Bias

The tendency to attribute one's own negative outcomes or transgressions to situational forces while taking credit for favorable accomplishments through internal traits.

Affect Heuristic ("How Do I Feel About It?")

An emotion-driven heuristic where consumers choose an option that produces immediate positive affective reactions, especially when cognitive processing capacity is constrained.

Choice Overload

A psychological paradox where an excessive number of choices attracts consumer interest initially but ultimately overwhelms cognitive capacity, decreasing participation and sales conversion.

The Jam Study

A classic retail experiment showing that a large display of $24$ jams drew more browsing shoppers ($60\%$) than $6$ jams ($40\%$), yet produced an inferior purchase rate of $3\%$ compared to $30\%$ for the small display.

401(k) Participation Choice Effect

A finding by Botti and Iyengar (2006) demonstrating that for every $10$-option expansion in retirement fund choices, projected individual employee participation rates dropped by $2\%$.

Gambler’s Fallacy

The erroneous assumption that independent random events will compensate for past streaks, believing that an event that has not occurred recently is now "due."

Hot Hand Belief

The cognitive presumption that an agent or event currently experiencing a streak of success will continue that streak, overweighting recent performance over historical baseline rates.

Illusion of Control

The cognitive bias where individuals overestimate their capacity to control or influence events governed entirely by chance, such as picking lottery tickets or rolling dice harder.

Willful Ignorance

The intentional avoidance of relevant and important information to shield oneself from guilt, ethical conflicts, or emotional distress.

Compensatory Decision Model

A comprehensive decision rule where consumers calculate holistic tradeoffs, allowing exceptional strengths on one attribute to make up for weaknesses on another.

Non-Compensatory Decision Model

A decision framework where options are screened against strict attribute thresholds, immediately eliminating any product that fails to satisfy a prerequisite requirement.

Survivorship Bias

A logical distortion resulting from evaluating only data points or entities that navigated a selective filter while ignoring those that vanished, exemplified by Abraham Wald's WWII aircraft armor analysis.

Sensory-Specific Satiety

A psychological state in which continued consumption of a food or product diminishes sensory pleasure specifically for that item, prompting consumers to seek alternative varieties.

Variety Seeking

The consumer behavioral tactic of selecting assorted options across consumption occasions to counter satiation, satisfy novelty needs, manage uncertainty, or signal sophistication.

Over-Variety

The tendency of consumers to select a wider assortment of items in simultaneous choice settings than they will actually enjoy or consume later.

Preference Mis-Forecasting

The systematic error where consumers fail to predict their future desires accurately, prompting excessive diversification when making decisions for future consumption periods.

Atmospherics

The strategic design of physical or digital commercial environments—including lighting, acoustics, aromas, color schemes, and layout—to influence customer emotions and purchase choices.

Post-Decision Regret

A cognitive and emotional reaction occurring after purchase when a consumer questions their choice and ponders whether an unchosen alternative would have yielded superior results.

Expectancy Disconfirmation Model

A framework stating that post-purchase consumer satisfaction is a function of the comparison between pre-purchase expectations and actual product performance.

Positive Disconfirmation

A post-purchase evaluation where delivered product performance surpasses pre-purchase customer expectations, creating delight.

Negative Disconfirmation

A post-purchase evaluation occurring when delivered performance fails to reach the benchmark of consumer expectations, producing dissatisfaction.

Attribution Theory of Blame

The psychological framework evaluating how consumers assign blame when an experience goes wrong based on locus of causality (who caused it), stability (is it recurrent), and controllability (could it be avoided).

Equity Theory

A fairness principle stating that consumers assess exchange interactions by weighing their personal cost-to-benefit ratio against the perceived cost-to-benefit ratio of transaction partners or peers.

Outcome Satisfaction

A consumer's subjective evaluation regarding the quality, utility, and desirability of the actual product or service received from an exchange.

Process Satisfaction

A consumer's evaluation of the overall procedural journey, ease of interaction, respect, and fairness experienced throughout the buying process.

Product Disposition

The terminal stage of consumer behavior where individuals decide whether to keep, donate, resell, recycle, trade in, or discard physical goods.
