The Fear Factor: A Neuroscientific Deconstruction of Why Fear Appeals Dominate Persuasive Marketing

The Primal Power of Fear in Persuasion

Introduction: Fear as a Foundational Human Motivator

The enduring effectiveness of fear-based marketing is not a product of clever psychological manipulation alone; it is a direct and potent exploitation of the human brain's most fundamental, hardwired survival circuits. A fear appeal is a persuasive message that attempts to arouse fear by presenting a risk, highlighting a vulnerability to that risk, and proposing a protective action to divert behavior.1 The strategy relies on creating a threat to an individual's physical, psychological, or social well-being to motivate a specific action, such as purchasing a product or endorsing a policy.3 The central thesis of this report is that fear marketing's dominance stems from its ability to tap into a primal, evolutionarily conserved emotion. Fear is hardwired into our neurobiology as a survival mechanism, activating the "fight-or-flight" response, which hijacks cognitive resources and primes us to seek immediate safety.5 This inherited neural architecture provides the unshakeable foundation upon which all fear-based persuasion is built.

The Psychology of Threat: From Survival Instinct to Consumer Behavior

The psychological mechanism underpinning a fear appeal is the deliberate stimulation of anxiety. The audience, experiencing this uncomfortable emotional state, is then motivated to reduce it by adopting the course of action recommended in the communication.3 In a consumer context, this primal drive is channeled into modern anxieties, such as the fear of making the wrong purchase, the fear of missing out (FOMO) on a social trend or limited-time offer, or tangible concerns over personal safety and financial security.5 A critical distinction exists between fear and anxiety, which marketers skillfully leverage. Fear is an immediate, intense emotional response to a present and identifiable threat.9 Anxiety, conversely, is a sustained state of apprehension about a potential, uncertain, or future threat.10 While an ad showing a home invasion triggers immediate fear, campaigns for insurance, retirement funds, or preventative health products prey on anxiety about what might happen. This distinction is crucial because it reveals that the power of fear marketing often lies not just in the emotion it evokes, but in the cognitive state of uncertainty it creates. Uncertainty itself is a powerful stressor that the brain is highly motivated to resolve.12 A fear appeal, therefore, functions by first inducing a state of uncomfortable uncertainty about a negative outcome. The advertised product or service is then positioned not merely as a solution to the threat, but as the most direct means of resolving the cognitive and emotional discomfort of uncertainty, a fundamental drive of the human brain.

The Neurobiology of a Fear Appeal: A Journey Through the Brain

The Dual-Process Pathway: The Brain's Fast and Slow Response to Threat

The brain processes threatening information via two distinct but parallel neural pathways, a duality that explains both the instantaneous impact and the potential for rational override of a fear appeal. The "Low Road" (Thalamo-Amygdala Pathway): This is a rapid, subconscious, and evolutionarily ancient circuit. When a potential threat is perceived, sensory information travels from the thalamus directly to the amygdala, bypassing the cerebral cortex. This pathway provides a fast but crude signal, allowing the amygdala to trigger an immediate, instinctive "fight-or-flight" response before the conscious brain has fully processed what is happening.14 This neurological shortcut explains the visceral, gut-level reaction to shocking imagery, sudden loud noises, or alarming statistics in an advertisement. The "High Road" (Thalamo-Cortico-Amygdala Pathway): This is a slower, more deliberate and analytical route. Sensory information is relayed from the thalamus to the sensory cortex and then to the prefrontal cortex (PFC) for detailed analysis, interpretation, and contextualization. The processed information is then sent to the amygdala, allowing for a more considered emotional response. This pathway enables the conscious brain to evaluate the threat and either confirm the initial alarm or regulate and suppress the fear response if the threat is deemed non-critical.14 The profound effectiveness of many fear appeals is a direct result of the neuro-architectural tension between these two pathways. Marketers strategically design messages to exploit the speed of the "Low Road," creating a potent emotional state before the "High Road's" rational analysis can fully engage. The advertised solution is then presented to a brain already in a state of heightened arousal, making the offer feel less like a sales pitch and more like a welcome resolution to an existing emotional crisis.

The Amygdala: The Brain's Sentinel and the Seat of Fear

The amygdala, a pair of almond-shaped nuclei located in the medial temporal lobe, is the brain's primary threat detection and fear processing center.9 Its principal function is to continuously scan the environment for salient, biologically relevant, and potentially dangerous stimuli.14 Upon detecting a threat, the amygdala initiates the cascade of physiological and behavioral changes known as the "fight-or-flight" response.5 Functional magnetic resonance imaging (fMRI) studies confirm that the amygdala exhibits disproportionately high activation in response to threatening stimuli, such as fearful facial expressions, and that this activation correlates with the accurate identification of fear.14 This innate sensitivity explains why the depiction of fearful or distressed faces in advertising serves as such a powerful and universal non-verbal cue, capable of capturing attention and signaling danger without a single word.

The Hippocampus: Encoding Fearful Memories and Context

The formation of lasting fear memories relies on a critical interaction between the amygdala and the hippocampus, a brain structure vital for the consolidation of long-term, explicit memories.16 During an emotionally arousing event, the amygdala modulates hippocampal activity, effectively "tagging" the experience as significant and prioritizing it for encoding into long-term memory.16 This is the neurobiological reason why fear-based advertisements are often far more memorable than neutral or positive ones; the brain is evolutionarily programmed to remember threats to its survival. Furthermore, the hippocampus is responsible for encoding the contextual details surrounding a fearful event—the "where" and "when" of the threat. This process, known as contextual fear conditioning, is how a previously neutral environment can become a powerful trigger for fear.15 Marketers leverage this by associating a common, relatable context (e.g., a family home at night, a crowded public space) with a specific threat (e.g., a burglary, a virus), thereby extending the feeling of vulnerability into the viewer's own life and making the advertised solution seem more personally relevant and necessary.

The Prefrontal Cortex (PFC): The Executive Controller and Emotional Regulator

The prefrontal cortex (PFC) serves as the brain's executive control center, responsible for rational thought, planning, and the top-down regulation of emotional responses generated by subcortical structures like the amygdala.15 The ventromedial prefrontal cortex (vmPFC), in particular, plays a critical role in integrating emotional input with complex decision-making, assessing the value and relevance of stimuli, and inhibiting the amygdala's fear output—a process known as fear extinction.15 In contrast, the dorsolateral prefrontal cortex (dlPFC) is more involved in executive functions such as working memory and cognitive control, acting as the brain's "willpower muscle" that can override impulsive, emotionally-driven behaviors with more considered, goal-oriented actions.22 A fear appeal engages the PFC by presenting a problem that requires a solution, prompting this region to evaluate the threat and the proposed remedy.

The Biochemical Cascade: Adrenaline and Cortisol

When the amygdala detects a threat, it triggers a rapid biochemical cascade that prepares the body for action. Adrenaline (Epinephrine): Released from the adrenal glands, adrenaline is the immediate-response hormone. It surges through the bloodstream, causing a rapid increase in heart rate, blood pressure, and blood glucose levels. This provides the body with a burst of energy and heightened alertness, creating the physiological sensations of arousal, urgency, and power that are characteristic of the "fight-or-flight" response.10 Cortisol: Known as the primary stress hormone, cortisol is released more slowly and sustains the body's heightened state of alert over a longer period. It helps mobilize energy reserves and, crucially, interacts with the amygdala and hippocampus to enhance the consolidation of fear memories, etching the threatening experience more deeply into the brain.23 This dual-hormone response ensures that a fear-inducing message is not only felt intensely in the moment but is also remembered long after the initial exposure. Brain Region Primary Function Role in Fear Appeal Amygdala Threat detection, fear activation, emotional memory modulation Triggers the initial "fight-or-flight" response; tags the message as important for memory. Hippocampus Formation of explicit, contextual memories Encodes the details and context of the threat, linking it to specific situations or environments. Ventromedial Prefrontal Cortex (vmPFC) Emotional regulation, value-based decision-making, fear extinction Evaluates the threat's relevance; can inhibit the amygdala's fear response. Key in processing the "efficacy" part of a message. Dorsolateral Prefrontal Cortex (dlPFC) Executive control, working memory, willpower, rationalization Engages in conscious problem-solving to address the threat; resolves cognitive dissonance created by the appeal.

From Threat to Action: The Cognitive Dynamics of Fear Marketing

Capturing the Brain's Spotlight: How Fear Hijacks Attention

Fearful stimuli are granted a privileged status in the brain's attentional systems. The activation of the brain's defense networks enhances the processing of any cues related to the threat, effectively forcing the individual to pay attention.24 This phenomenon often results in a narrowing of the attentional field, a state sometimes described as "tunnel vision," where cognitive resources are intensely focused on the source of the fear and the immediate environment, while non-essential information is filtered out.25 This attentional capture is not a conscious choice but a neurobiological imperative. The amygdala directly modulates activity in sensory processing areas, such as the visual cortex, essentially instructing them on what to prioritize.14 This is why viewers often find it difficult to "look away" from a frightening or graphic advertisement; their brain is hardwired to monitor the threat.

The Memory Enhancement Effect: Why Fearful Events are Better Remembered

The robust connection between the amygdala and the hippocampus ensures that emotionally charged events are encoded more deeply and are more resistant to being forgotten than neutral experiences.16 The surge of stress hormones like adrenaline and cortisol during the fear response acts as a neurochemical accelerant, further strengthening the consolidation of these memories in the brain.23 This memory enhancement effect is a cornerstone of public health campaigns that utilize graphic, fear-inducing imagery to discourage behaviors like smoking or dangerous driving.3 The message becomes memorable because the brain is evolutionarily designed to retain information critical to survival.

Inducing Cognitive Dissonance: The Psychological Discomfort That Demands Resolution

A key psychological mechanism activated by fear appeals is cognitive dissonance. This is the state of mental discomfort that arises when an individual holds two or more conflicting beliefs, values, or cognitions—for example, the belief "I am a safe and responsible person" conflicting with the new information "My current behavior puts me at serious risk".22 Fear-based advertisements are expertly crafted to induce this state by presenting a threat that directly challenges a person's positive self-concept or sense of security. Neuroimaging studies reveal that the experience of cognitive dissonance activates brain regions associated with conflict monitoring and negative emotional states, such as the anterior cingulate cortex and the anterior insula, signaling to the brain that something is wrong and must be resolved.29

How Action Alleviates Dissonance: The Neurological Basis for Choice-Induced Preference Change

The brain is powerfully motivated to reduce the discomfort of cognitive dissonance. Since altering a core belief about oneself is psychologically difficult, the path of least resistance is often to change the conflicting behavior. The decision to take action—to buy the product or adopt the recommended behavior—is therefore a profound act of psychological self-regulation. fMRI studies have shown that the process of making a choice to resolve dissonance and subsequently rationalizing that choice engages the prefrontal cortex (specifically the right inferior frontal gyrus and medial fronto-parietal regions) and the ventral striatum, a key node in the brain's reward system.29 This neural process underlies the phenomenon of "choice-induced preference change," where individuals, after choosing one option over another, subsequently rate their chosen option more favorably and the rejected option more negatively. This shift is not merely a self-reported justification; it is reflected in underlying brain activity, suggesting that the brain actively rewires its preferences to align with the action taken.29 Consequently, the ultimate goal of a fear appeal is not merely to scare the consumer, but to create a state of cognitive dissonance that can only be satisfactorily resolved by taking the marketer's proposed action. The purchase becomes a self-justifying act that restores cognitive consistency, a process that is neurally reinforced and psychologically rewarding.

The Fear Appeal Formula: Threat, Efficacy, and the Extended Parallel Process Model (EPPM)

Deconstructing the Message: Perceived Threat and Perceived Efficacy

A successful fear appeal is a carefully constructed message with two essential components: a credible threat and a viable solution. The absence of either component renders the message ineffective.3 Perceived Threat: This is the part of the message that establishes the risk. It is composed of two sub-components: Perceived Severity: The individual's belief about the magnitude and seriousness of the threat (e.g., "Driving while tired can lead to a fatal accident").32 Perceived Susceptibility: The individual's belief about their personal vulnerability or likelihood of experiencing the threat (e.g., "I often drive long distances and could be at risk for fatigue-related accidents").32 Perceived Efficacy: This is the part of the message that provides the solution and empowers the individual to act. It also has two sub-components: Response Efficacy: The belief that the recommended action is effective in averting the threat (e.g., "Taking a 15-minute break every two hours is proven to reduce the risk of crashing").32 Self-Efficacy: The individual's belief in their own ability to successfully perform the recommended action (e.g., "I am capable of planning my trip to include regular rest stops").32

The EPPM Framework: Predicting Consumer Response

The Extended Parallel Process Model (EPPM) is the leading theoretical framework used to explain and predict the outcomes of fear appeals.32 The model proposes that an individual engages in a two-stage appraisal process upon receiving a fear-based message. First, they appraise the threat. If the perceived threat is low, they are unmotivated to process the message further, and it is largely ignored. If, however, the perceived threat is high, they become motivated by fear to address the danger and proceed to the second stage: appraising the efficacy of the recommended solution.33

Danger Control: The Path to Persuasion

When an individual perceives both a high level of threat and a high level of efficacy, they are predicted to enter a danger control process.36 In this state, their cognitive efforts are focused on managing the danger itself. They are motivated to adopt the recommended strategies to avert the threat. This cognitive pathway leads to message acceptance, attitude change, and the adoption of protective behaviors, which is the intended and successful outcome of a fear appeal campaign.34

Fear Control: The "Boomerang Effect" and Message Rejection

Conversely, when an individual perceives a high level of threat but a low level of efficacy, they enter a fear control process.36 In this state, the individual believes the threat is severe and they are susceptible, but they feel helpless or incapable of averting it. The overwhelming emotion of fear itself, rather than the external danger, becomes the primary problem to be managed. This leads to maladaptive coping responses designed to reduce the feeling of fear, which results in message rejection. These responses include: Defensive Avoidance: Actively ignoring or tuning out the message to avoid the unpleasant feelings it evokes.38 Denial: Dismissing the threat as exaggerated or irrelevant to oneself.3 Reactance: A motivational state where an individual feels their freedom is being threatened, leading them to deliberately engage in the risky behavior to reassert their autonomy.41 This fear control pathway is the mechanism behind the "boomerang effect," where a poorly constructed fear appeal—one that instills significant fear without providing a clear and achievable solution—can inadvertently reinforce the very behavior it seeks to prevent.35

Finding the Sweet Spot: The Debate on Optimal Fear Levels

While early theories posited an inverted U-shaped relationship, suggesting that moderate levels of fear were most persuasive, this has been largely superseded.7 A large body of meta-analytic evidence now supports a positive linear relationship: stronger fear appeals are more effective than weaker ones, with one critical condition— the message must also contain a strong efficacy component.44 The key to success is not to moderate the fear, but to ensure that the sense of empowerment and the viability of the solution are scaled to match the intensity of the threat. When efficacy is high, there are no identified circumstances under which strong fear appeals backfire.45 This reveals a crucial dimension of the EPPM: successful fear appeals are not solely about fear, but about the dynamic relationship between fear and empowerment. The threat component of a message is designed to evoke fear, but the efficacy component serves a different emotional purpose. According to appraisal theories of emotion, information that instills confidence in one's ability to cope with a challenge generates hope.47 Therefore, a masterfully crafted fear appeal is not a monologue of dread, but a narrative that skillfully transitions the audience from a state of fear to a state of hope. The persuasion occurs within this emotional pivot, transforming a passive, fearful viewer into an active, hopeful agent of change.

High Perceived Efficacy Low Perceived Efficacy High Perceived Threat Danger Control Message Acceptance, Adaptive Behavior Change. Strategy: Provide clear calls to action. Fear Control Message Rejection, Defensive Avoidance, Denial. Strategy: Educate about solutions and build self-efficacy. Low Perceived Threat Low Motivation Message may be acknowledged but little action taken. Strategy: Increase perception of risk and susceptibility. No Response Message Ignored. Strategy: Educate about both risk and solutions.

The Individual in the Crosshairs: Personality, Genetics, and Susceptibility

Why Fear is Not a Monolith: Individual Differences

The impact of a fear appeal is not uniform across an audience; its effectiveness is significantly moderated by the psychological and cultural characteristics of the recipient.1 Factors such as age, gender, coping style, self-esteem, and cultural background can all influence how a threatening message is processed.1 For example, some research suggests that individuals from collectivistic cultures, which prioritize group harmony, may be more responsive to threats of social rejection, whereas those from individualistic cultures may be more motivated by threats to personal safety and autonomy.48

The Neuroticism Factor: Heightened Threat Sensitivity

A particularly important moderator is the personality trait of neuroticism. As one of the "Big Five" personality dimensions, neuroticism is defined by a stable tendency to experience negative emotions—including fear, anxiety, anger, and sadness—more frequently and with greater intensity.11 Individuals scoring high in neuroticism are predisposed to interpret ambiguous situations as threatening, to react more strongly to stressors, and are at a significantly higher risk for developing clinical anxiety and depressive disorders.20 Neuroscientific investigations have revealed that neuroticism is not necessarily linked to a hyperactive amygdala in isolation, but rather to altered functional connectivity between the amygdala and the ventromedial prefrontal cortex (vmPFC).20 This suggests a relative failure of the PFC's top-down regulatory control over the amygdala's emotional output. In essence, individuals high in neuroticism possess a less effective neural "brake" on their fear response, making them biologically more susceptible to threat-based messaging.

Anxiety Sensitivity and Harm Avoidance: The Neurobiological Underpinnings

Beyond broad personality traits, specific cognitive sensitivities also predict responses to fear. Anxiety Sensitivity (AS) is the specific fear of anxiety-related bodily sensations (e.g., a racing heart, dizziness), which are misinterpreted as signs of a catastrophic physical or mental event.53 Neuroimaging studies have linked high AS to greater activation in the anterior insula, a brain region critical for interoception—the sensing of internal physiological states. This suggests that high-AS individuals have a heightened neural sensitivity to the physical feelings of fear itself.53 Harm Avoidance (HA) is a temperament trait characterized by excessive worry, shyness, and a tendency toward behavioral inhibition to avoid punishment or novelty.54 Meta-analyses of neuroimaging studies have associated high HA with distinct patterns of brain structure and function, including altered gray matter volume and resting-state activity in regions of the prefrontal, temporal, and parietal cortices.54

Implications for Psychographic Targeting

These individual differences in personality and temperament represent pre-existing vulnerabilities that can be targeted by sophisticated marketing. Individuals high in neuroticism, anxiety sensitivity, or harm avoidance are theoretically prime targets for fear appeals because their brains are already wired for heightened threat detection and a more robust negative emotional response. This provides a clear, if ethically challenging, basis for psychographic segmentation, where marketers can develop distinct customer personas based on these psychological traits and tailor fear-based messages accordingly.55 The neural correlates of these traits provide a biological explanation for why the EPPM's "Fear Control" pathway is more readily triggered in some individuals. For a person high in neuroticism, a given threat is likely to be perceived as more severe and more personally susceptible due to their inherent threat sensitivity and weaker emotional regulation. This amplification of perceived threat makes it far more likely to overwhelm their sense of efficacy, pushing them directly into a state of defensive avoidance or denial. This underscores why a "one-size-fits-all" fear appeal is a flawed strategy; marketers are not addressing a uniform audience, but a collection of differently wired brains.

The Future of Fear: Hyper-Personalization, AI, and Neuroethics

Hyper-Personalized Fear Appeals: The Power of AI and Big Data

The future of fear marketing lies in the convergence of artificial intelligence (AI), big data analytics, and dynamic creative optimization (DCO). Hyper-personalization is a strategy that moves beyond simple demographic targeting to deliver experiences tailored to an individual's real-time behaviors, preferences, and psychological states.58 This is made possible by machine learning (ML) models that can now reliably infer complex psychological traits, including the Big Five personality dimensions like neuroticism, from an individual's digital footprint—their social media activity, search history, location data, and even patterns of mobile phone use.59 This technological leap enables a new frontier of marketing: the ability to identify individuals who are psychologically predisposed to be susceptible to fear appeals and then target them with hyper-personalized messages. Dynamic Creative Optimization (DCO) platforms can automatically assemble and serve advertisements with the precise imagery, copy, and call-to-action most likely to resonate with that individual's specific anxieties and motivations.61 This creates the potential for a "perfect storm" of manipulation: an automated system that can identify a person's deepest anxieties in real-time and instantly generate a bespoke fear appeal to exploit that specific vulnerability. This represents a qualitative shift from mass marketing to automated, individualized psychological influence.

The Ethics of Neuromarketing: Persuasion vs. Manipulation

This new capability forces a critical examination of the line between ethical persuasion and unethical manipulation.63 Persuasion is generally understood as the use of appeals and information to help a consumer make an informed choice that aligns with their own best interests. Manipulation, in contrast, involves the use of deceptive tactics or the exploitation of psychological vulnerabilities to subvert an individual's rational decision-making for the marketer's gain, often to the consumer's detriment.65 Hyper-personalized fear appeals that target inferred, subconscious traits like neuroticism or anxiety sensitivity risk crossing this line decisively. They operate by identifying and leveraging vulnerabilities that the consumer may not even be aware of, undermining their capacity for autonomous, rational choice.64

Cognitive Liberty and Neurorights: Protecting the Sanctity of the Mind

These technological advancements bring to the forefront the emerging ethical concept of Cognitive Liberty, or "neurorights." This principle posits that individuals have a fundamental right to control their own mental processes, free from non-consensual monitoring, alteration, or manipulation.67 The use of AI and neurotechnologies to build psychological profiles for the purpose of commercial targeting poses a direct and unprecedented threat to this liberty, raising profound questions about mental privacy and the nature of free will in the digital age.67

The Regulatory Landscape: Platform Policies and Data Privacy

Existing regulatory frameworks offer some protection, though their adequacy in the face of rapid technological change is debatable. Platform Policies: Major advertising platforms like Google and Meta have policies that prohibit "shocking content," "sensationalism," and the exploitation of crises or sensitive events.70 Meta's policies are particularly stringent regarding ads that assert or imply personal attributes, including physical or mental health conditions, which could be interpreted to restrict advertising based on inferred neuroticism or anxiety.73 However, the automated and dynamic nature of AI-driven campaigns presents significant enforcement challenges. Data Privacy Laws: The General Data Protection Regulation (GDPR) in Europe provides a strong legal foundation for user control. Article 21, the "right to object," gives individuals an absolute right to stop their data from being used for direct marketing purposes, including profiling.75 Article 22 provides protections against purely automated decision-making that has significant effects on an individual. These regulations empower consumers to resist the data collection that fuels psychological profiling.

Recommendations for Ethical and Effective Application

Synthesizing the neuroscientific, psychological, and ethical dimensions of fear appeals leads to a clear set of best practices for responsible and effective communication. The core principle is to shift the focus from fear to empowerment.

Principle Ethical Persuasion (Danger Control) Unethical Manipulation (Fear Control) Threat Presentation Present a credible, realistic threat relevant to the audience. Ground claims in facts and statistics.8 Exaggerate or fabricate threats. Use shocking imagery without context or solution. Promote unfounded fears.71 Efficacy & Empowerment Provide a clear, accessible, and effective solution. Build the consumer's self-efficacy and sense of agency. Frame the solution as a path to a hopeful outcome.57 Present a threat with no clear solution, inducing helplessness. Offer a solution that is ineffective or misleading.8 Audience Targeting Segment based on relevant behaviors and needs, respecting privacy and consent. Use positive framing and empowerment for all segments.81 Target vulnerable groups (e.g., children, anxious individuals). Use inferred psychological traits like neuroticism to exploit subconscious anxieties without consent.60 Transparency & Regulation Be transparent about data use. Comply with GDPR's right to object and platform policies on sensitive content.73 Use "stealth neuromarketing" to bypass conscious awareness. Collect and use psychological profile data without explicit, informed consent.64

Ultimately, the most powerful and ethical application of this knowledge is not to simply scare consumers, but to understand the neurobiology of fear in order to craft messages that effectively guide them toward a sense of safety, control, and hope. By presenting a credible threat and immediately coupling it with an empowering and achievable solution, marketers can align their objectives with the brain's fundamental drive to not only avoid danger but to actively seek security and well-being. 참고 자료 Fear appeal - Wikipedia, 8월 5, 2025에 액세스, https://en.wikipedia.org/wiki/Fear_appeal (PDF) Fear Appeal Theory - ResearchGate, 8월 5, 2025에 액세스, https://www.researchgate.net/publication/265807800_Fear_Appeal_Theory The Use of Fear Appeals to Communicate Public ... - SWORD - CIT, 8월 5, 2025에 액세스, https://sword.cit.ie/cgi/viewcontent.cgi?article=1030&context=irishbusinessjournal Appeal to Fear Marketing Psychology: Does Scaring Your Buyer Work?, 8월 5, 2025에 액세스, https://chantellemarcelle.com/fear-appeal-marketing-psychology/ The Power of Fear in Consumer Psychology - The Upward Spiral Group, 8월 5, 2025에 액세스, https://www.upwardspiralgroup.com/blog/the-power-of-fear-in-consumer-psychology Psychology of Fear in Advertising - Unleashing Emotional Impact in Marketing - Markitome, 8월 5, 2025에 액세스, https://markitome.com/psychology-of-fear-in-advertising/ Effects of Anti-Smoking Advertisements on Young People: Role of Gender and Level of Smoking - Athens Journal, 8월 5, 2025에 액세스, https://www.athensjournals.gr/media/2019-5-4-4-Chung.pdf Scare Tactics in Advertising: How Businesses Use Fear In Sales - Nudgify, 8월 5, 2025에 액세스, https://www.nudgify.com/scare-tactics-in-advertising/ The Role of the Amygdala in Human Behavior and Emotion, 8월 5, 2025에 액세스, https://www.verywellmind.com/the-role-of-the-amygdala-in-human-behavior-and-emotion-7499223 What is Adrenaline?
