Risk as feelings
The assumption and process where people assess risks and uncertainties primarily based on their fast, intuitive, and automatic emotional reactions to potential hazards
Risk as analysis
The theoretical perspective assuming people form risk judgments by logically and mathematically integrating the desirability and statistical probability of possible outcomes
Affect heuristic
A cognitive shortcut where individuals make complex decisions and weigh risks and benefits by relying directly on the general positive or negative feelings a stimulus evokes
Integral affect
Positive or negative feelings that are directly, naturally, and inextricably linked to the conscious representation of a specific stimulus or decision (e.g., the innate fear of cancer)
Incidental affect
Background feelings or moods completely unrelated to the current decision (such as the weather) that unconsciously color the evaluation of a stimulus

Objective numeracy
The factual, measurable ability of an individual to adequately process mathematical principles, basic probabilities, and statistical concepts in daily life
Appraisal-tendency framework
A theory stating that specific, discrete emotions (like anger or fear) trigger unique cognitive appraisal dimensions (like personal control or certainty) which systematically influence risk perceptions

Cultural cognition theory
The theory describing that individuals form factual beliefs and risk perceptions primarily to keep them aligned with the fundamental values of the social groups they identify with
Bounded rationality
The fundamental concept that humans have limited mental capacity and time to consciously process all complex information, forcing them to simplify decision-making
Heuristic
A simple cognitive decision rule or mental shortcut that allows individuals to quickly form a judgment without analyzing all available details
Attribute substitution
The underlying cognitive process where a person unconsciously and automatically replaces a complex or abstract assessment question with a simpler, easier-to-answer question
Conjunction fallacy
A statistical error where an individual falsely judges that the simultaneous occurrence of two specific events is more probable than the occurrence of one of those events alone

Ecological rationality
The degree to which a specific decision rule or heuristic is extremely successful and accurate purely because it is optimally adapted to the statistical structure of its environment
Adaptive toolbox
The complete evolutionary or experience-based repertoire of different fast and frugal heuristics that an individual can unconsciously draw upon depending on the situation
Nudge
A subtle psychological intervention by choice architects in the physical or informational environment that steers human behavior in a predictable direction without forbidding options
Fast-and-frugal decision trees
Extremely simple, rule-based flowcharts requiring only a few sequential 'yes' or 'no' questions, designed to force quick and accurate decisions under heavy time pressure
Hindsight bias
The psychological phenomenon where individuals, after learning the factual outcome, falsely believe that the facts perfectly match what they had already intuitively predicted beforehand
Affect
The immediate, often unconscious emotional and intuitive reactions or moods that patients experience when processing medical information, which drive their ultimate behavior
Affect-rich
A characteristic of risks or medical outcomes (like severe physical complications) that evokes very vivid, powerful emotional reactions, pushing logical risk assessment into the background
Information evaluability
The psychological degree to which it is possible or easy for a decision-maker to intuitively assess the emotional meaning (good or bad) of an isolated mathematical number without a frame of reference
Comparative risk statistics
Additional contextual statistical data (such as the population average) presented to give a personal percentage meaning, fundamentally steering a patient's perception
Evaluative labels
Simple, subjective categorizations or judgmental words (like 'negative', 'positive', or 'low risk') added to medical statistics that directly guide the patient's emotional core meaning
Cancer recurrence
The medical risk of a previously treated tumor returning, which is psychologically accompanied by a much deeper, unique fear compared to an unknown new illness
According to the Appraisal-Tendency Framework, how do fear and anger differ in shaping risk perception?
Fear is characterized by low certainty and low control, leading to higher risk estimations, while anger involves high certainty and high control, leading to lower risk estimations
In the affect heuristic model by Alhakami and Slovic, what happens to risk and benefit judgments when a person has a strong positive affect toward a hazard?
The person will judge the benefits of the hazard as high and the risks as low, showing an inverse relationship

What are the four main functions of affect in decision-making?
Affect serves as information, as a spotlight, as a motivator, and as a common currency
What is the "local warming effect" mentioned in the literature?
The cognitive bias where people are more likely to believe in the long-term risk of global warming on a day when the local daily temperature happens to be unusually high
What is the core difference between a "nudge" and a "boost" in risk intervention?
A nudge subtly alters the choice environment to steer behavior using heuristics, whereas a boost aims to structurally improve the individual's own decision-making skills and competencies
According to the literature on heuristics, what cognitive bias explains why people fear highly unlikely events like airplane crashes or terrorist attacks?
The availability heuristic, because these events are highly publicized and easily retrieved from memory
Imagine a doctor tells a patient they have a "10% chance" of a side effect, while another doctor tells a different patient they are among the "10 out of 100" who will experience it. Based on the literature, predict how the reactions will differ.
According to the literature on presentation formats, the "10 out of 100" frequency format will evoke much more vivid, frightening imagery and result in a significantly higher emotional risk perception than the abstract "10%" probabilistic format
A highly numerate scientist and a low numerate citizen are reviewing a complex chart about climate change risks. How will their personality differences influence their processing?
Based on objective numeracy literature, the low numerate citizen will rely heavily on superficial affective cues and formats, while the highly numerate scientist extracts precise meaning from the probabilities. However, according to cultural cognition theory, the highly numerate scientist is actually most at risk of polarizing and filtering the data to fit their specific social group's worldview
A patient is choosing between Treatment A, which has a 5% mortality risk but causes a highly visible stoma, and Treatment B, which has a 10% mortality risk but no visible side effects. The patient chooses Treatment B. Explain this using the emotional theories of risk.
The stoma is an "affect-rich" outcome. According to the functions of affect, the emotion acts as a "spotlight" directing disproportionate attention to the vivid, frightening complication, causing the patient to completely ignore the logical mathematical reality that Treatment B is twice as deadly
During a pandemic, a news anchor states: "Look at the hospitals, there are way more vaccinated people admitted than unvaccinated people, so the vaccine clearly doesn't work!" What specific cognitive error is the anchor making according to the heuristic literature?
Base rate neglect. The anchor is utilizing the representativeness heuristic and completely ignoring the total population size (the denominator), failing to realize that the vaccinated group in the general population is vastly larger than the unvaccinated group

A government agency wants patients to estimate their personal risk of heart disease on a form before giving them their actual diagnostic test results. Why is this a bad strategy according to the empirical literature?
This will induce hindsight bias. The act of making an initial estimate fundamentally alters how the subsequent factual information is received; patients will falsely conclude that their actual results align perfectly with their prior intuitive estimate, diminishing the educational value of the real statistics
