Appeal to emotion or argumentum ad passiones ("argument from passion") is a logical fallacy characterized by the manipulation of the recipient's emotions in order to win an argument, especially in the absence of factual evidence. This kind of appeal to emotion is a type of red herring and encompasses several logical fallacies, including appeal to consequences, appeal to fear, appeal to flattery, appeal to pity, appeal to ridicule, appeal to spite, and wishful thinking.
Instead of facts, persuasive language is used to develop the foundation of an appeal to emotion-based argument. Thus, the validity of the premises that establish such an argument does not prove to be verifiable.
Appeals to emotion are intended to draw inward feelings such as fear, pity, and joy from the recipient of the information with the end goal of convincing him/her that the statements being presented in the fallacious argument are true.

Classical times
The power of emotions to influence judgment, including political attitudes, has been recognized since classical antiquity. Aristotle, in his treatise Rhetoric,
described emotional arousal as critical to persuasion, "The orator
persuades by means of his hearers, when they are roused to emotion by
his speech; for the judgments we deliver are not the same when we are
influenced by joy or sorrow, love or hate."
Aristotle warned that emotions may give rise to beliefs where none
existed, or change existing beliefs, and may enhance or decrease the
strength with which a belief is held.
Seneca similarly warned that "Reason herself, to whom the reins of
power have been entrusted, remains mistress only so long as she is kept
apart from the passions."
Centuries later, French scientist and philosopher, Blaise Pascal wrote that "People [...] arrive at their beliefs not on the basis of proof, but on the basis of what they find attractive." Baruch Spinoza
characterized emotions as having the power to "make the mind inclined
to think one thing rather than another." Disagreeing with Seneca the Younger that emotion destroys reason, the 18th century Scottish philosopher George Campbell
argued, instead, that emotions were allies of reason, and that they aid
in the assimilation of knowledge. However, Campbell warned of the
malleability of emotion and the consequent risk in terms of
suggestibility:
[Emotions] are not supplanters of reason, or even rivals in her sway; they are her handmaids, by whose ministry she is enabled to usher truth into the heart, and procure it to favorable reception. As handmaids, they are liable to be seduced by sophistry in the garb of reason, and sometimes are made ignorantly to lend their aid in the introduction of falsehood.
Drawing on the social psychology of his day, propaganda theorist Edward Bernays
confidently asserted that "in certain cases we can effect some change
in public opinion with a fair degree of accuracy by operating a certain
mechanism, just as a motorist can regulate the speed of his car by
manipulating the flow of gasoline." Bernays advised that to change the attitudes of the masses, a propagandist should target its "impulses, habits and emotions" and make "emotional currents" work to achieve the goal.
Indeed, some contemporary writers have attributed the popularity
of the most destructive political forces in modern history—from Nazism
to Jihadism—to the ability of their leaders to enchant (rather than
convince) publics and to oppose "the heavenly ecstasies of religious
fervor" to the "naked self interest" and the icy, individualistic
rationalism of modern liberalism.
Similarly, Drew Westen, professor of psychology psychiatry and
behavioral sciences at Emory University, drawing on current psychiatric
and psychological research to demonstrate the power of emotions in
affecting political cognition and preferences, wrote that, "when reason
and emotion collide, emotion invariably wins." Westen, an advisor to Democratic political campaigns, believes that
evolution has equipped people to process information via emotions and
that people respond to emotional cues more than to rational arguments.
Accordingly, Westen believes that emotion lies at the center of
effective persuasion and that appeals to emotion will always beat
appeals to reason:
A central aspect of the art of political persuasion is creating, solidifying, and activating networks that create primarily positive feelings toward your candidate or party and negative feelings toward the opponent …
You can slog it for those few millimeters of cerebral turf that process facts, figures and policy statements. Or you can … target different emotional states with messages designed to maximize their appeal.
Modern theories
A
social psychology theory posits that attitudes have three
components—affect, cognition and behavior. The cognitive dimension
refers "to beliefs that one holds about the attitude object, and
behavior has been used to describe overt actions and responses to the
attitude object." Affect, meanwhile, describes "the positive and
negative feelings that one holds toward an attitude object", that is,
the emotional dimension of an attitude.
Modern theorists have modified the tripartite theory to argue that an
attitude "does not consist of these elements, but is instead a general
evaluative summary of the information derived from these bases."
Political scientist George Marcus (writing with Russell Neuman
and Michael Mackuen) identifies two mental systems through which reason
and emotion interact in managing and processing political stimuli:
First, the disposition system "provides people with an understanding, an emotional report card, about actions that are already in their repertoire of habits." That is, the first system is that which monitors the casual processing of political information through habit, through which most of our information processing is done.
The second system, the surveillance system, "acts to scan the environment for novelty and sudden intrusion of threat."
In other words, the second system monitors the environment for any
signs of threat. If a threat is found, that system takes people out of
habitual, casual processing and puts them in a state of alertness and
receptivity to new information:
[W]hat is interesting about this second emotional system is that the onset of increased anxiety stops ongoing activity and orients attention to the threatening appearance so that learning can take place. [...] when the system detects unexpected of threatening stimuli, however, it evokes increased anxiety, it interrupts ongoing activity, and it shifts attention away from the previous focus and toward the intrusive stimuli.
Marcus further argues that "emotional engagement will motivate people
toward making more deeply reasoned decisions about politics than those
who remain dispassionate."
Other thinkers have argued that "when an emotion is aroused and
experienced, it can involve a number of psychological processes that can
then be used as a platform for promoting and securing influence and
compliance."
Regardless, it would stand to reason, then, that affecting a
subject's emotional state, in conjunction with a political message,
could affect that subject's attitudes.
In modern philosophy, there are two core appeals to emotion. One is the appeal to force (known as ad baculum) the other is the appeal to sympathy, known as ad misericordiam. These are only considered fallacies when used in doxastic systems.
Research
Accepted wisdom
is that, "[w]hen it comes to issues of emotional importance, convincing
someone to change his or her existing beliefs appears to be a virtually
hopeless undertaking." And yet, manipulating emotions may hold the key to shaping attitudes:
[T]he use of emotions to instill beliefs is prevalent in political propaganda. Depicting individuals, groups, or issues from an emotional perspective, or as actors in emotional events, evokes emotion. It thereby slips the belief that the emotion is about into the listener's mind. Presumably, it slips the beliefs into the listener's mind more easily, smoothly and unquestioned than would happen when the information alone was transmitted.
Though it is still a very undeveloped area of research, a number of
scholars are demonstrating that manipulating emotions surrounding a
persuasive message does affect that message's effectiveness. It has been
shown, for example, that people tend to adjust their beliefs to fit
their emotions, since feelings are treated by people as evidence, and
when feelings match beliefs, that is seen as validation of the
underlying beliefs.
Other research shows that "emotional stimuli can influence judgment
without a judge's awareness of having seen or felt anything (e.g.,
Bargh, 1997; Murphy & Zajonc, 1993)."
Indeed, "recent studies have confirmed that affect does play a
general role in attitude change, whether due to persuasive
communication, or to cognitive dissonance processes (Petty et al.,
2001)."
Psychologists Petty & Cacioppo found that there are two ways
of processing persuasive messages: (1) to focus on the content and
quality of the message (central processing), or (2) to focus instead on
external cues (such as the source of the message) and to disregard its
content (peripheral processing). "When participants use the
central/systematic route of responding to message content, they tend to
be persuaded more by strong arguments, and less by weak arguments.
However, the strength of the argument matters less when the peripheral
route is chosen. In that case, other "peripheral" factors, such as the
credibility of the source of the message or the intention of the
communicator become important in the persuasive process." Petty and
Cacioppo suggest that negative affect should lead to more central
processing and positive affect to more peripheral processing. That is,
"In happy moods, people tend to be persuaded equally by strong and weak
arguments, whereas in sad moods, people are persuaded only by strong
arguments and reject weak arguments."
Said otherwise, positive moods increase the reliance on positive
beliefs, whereas negative moods encourage the updating of beliefs in the
light of new, significant data.
Drawing on the work of Marcus, political scientist Tom Brader
says that, "by appealing to specific emotions, [communicators] can
change the way citizens respond to political messages."
Influence of emotion on persuasion
Negative emotions
Fear and anxiety
The
only widely studied emotion, with respect to persuasion, is fear. Fear
has been found to force individuals "to break from routine and pay close
attention to the external world," including persuasive messages.
Moreover, fear has been found to encourage political engagement:
[P]eople are demonstrably more likely to engage in the political realm when they are anxious about the candidates. Uneasiness about the available political choices leads people to pay closer attention to the political environment. [...] people learn more about the candidates (that is they acquire new and accurate knowledge) when they are anxious but not when they are enthusiastic about those candidates who dominate the political field.
More generally, "fear is associated with both attitude and behavior change."
However, "four variables that may interact to influence processing
depth of a fear-inducing message: (a) type of fear (chronic vs. acute),
(b) expectation of a message containing reassuring information, (c) type
of behavior advocated (e.g., disease detection vs. health promotion),
and (d) issue familiarity."
Guilt
Guilt is
the emotion that arises when an individual breaks an internalized moral,
ethical or religious rule. Guilt's effect on persuasion has been only
cursorily studied. Not unlike fear appeals, the literature suggests that
guilt can enhance attainment of persuasive goals if evoked at moderate
levels.
However, messages designed to evoke high levels of guilt may instead
arouse high levels of anger that may impede persuasive success.
Anger
Anger's
effect on persuasion has also seldom been studied. A couple of studies,
however, "suggest that a positive relationship exists between anger and
attitude change."
Specifically, researchers found that "anger evoked in response to
issues of juvenile crime and domestic terrorism correlated with
acceptance of legislative initiatives proposed to address those issues." Not unlike fear, anger was associated with close (central) information processing including of persuasive messages.
At the same time, "unintentionally induced anger in response to
supposed guilt and fear appeals has been shown to correlate negatively
with attitudes."
Sadness
Sadness arousal has been associated with attitude change in the context of AIDS, illicit drugs, and juvenile crime.
Disgust
Disgust
arousal, in the context of messages opposing animal experimentation, is
correlated negatively with attitude change. This is consistent with the
view that disgust leads to a rejection of its source.
Empathy and compassion
A
number of recent studies support the role of compassion in skewing
moral judgment. The researchers’ findings show there is a key
relationship between moral judgment and empathic concern in particular,
specifically feelings of warmth and compassion in response to someone in
distress.
Images of suffering children are the ideal triggers of this instinctive compassion.
Once triggered, compassion leads individuals to favor the few
they see suffering over the many who they know to be suffering but in
the abstract: "People who feel similar to another person in need have
been shown to experience more empathic compassion for that person than
do those not manipulated to feel similar to another."
Dan Ariely
notes that appeals that, through visual cues or otherwise, make us
focus on specific, individual victims affect our attitudes and lead us
to take action whereas, "when many people are involved, we don’t. A cold
calculation does not increase our concern for large problems; instead,
it suppresses our compassion."
In many ways, it is very sad that the only effective way to get people to respond to suffering is through an emotional appeal, rather than through an objective reading of massive need. The upside is that when our emotions are awakened, we can be tremendously caring. Once we attach an individual face to suffering, we’re much more willing to help, and we go far beyond what economists would expect from rational, selfish, maximizing agents.
Positive emotions
Pride
"Little
studied in the social influence context, the one clearly identifiable
study of pride and persuasion considered the role of culture in response
to advertising, finding that members of a collectivist culture (China)
responded more favorably to a pride-based appeal, whereas members of an
individualist culture (the United States) responded more favorably to an
empathy-based appeal."
Relief
Some
researchers have argued that anxiety which is followed by relief leads
to greater compliance to a request than fear, because the relief causes a
temporary state of disorientation, leaving individuals vulnerable to
suggestion. The suggestion is that relief-based persuasion is a function of less careful information processing.
Hope
Experiments
have shown that hope appeals are successful mainly with subjects who
self-report as being predisposed to experiencing fear
