Every day it seems like we feel hundreds of different emotions ā each nuanced and specific to the physical and social situations we find ourselves in.
According to science, itās not that complicated by a long shot. A new study says weāre really only capable of four ābasicā emotions: happy, sad, afraid/surprised, and angry/disgusted.
But much like the āmother saucesā of cooking allow you to make pretty much any kind of food under the sun, these four āmother emotionsā meld together in myriad ways in our brains to create our layered emotional stews.
Robert Plutchikās famous āwheel of emotionsā shows just some of the well known emotional layers.

In this post weāll take a close look at each of the four emotions, how they form in the brain and the way they can motivate us to surprising actions.
Happiness makes us want to share
Psychoanalyst Donald Winnicott discovered that our first emotional action in life is to respond to our motherās smile with a smile of our own. Obviously, joy and happiness are hard-wired into all of us.
The left pre-frontal cortex of the brain is where happiness traits like optimism and resilience live. A study done at the Laboratory for Affective Neuroscience watched Buddhist Monks and found that the left prefrontal lobe of their brains lit up as they entered a blissful state of meditation.
Other than making us ā¦ well, happy ā¦ joy can also be a driver of action. Winnicottās discovery of a babyās āsocial smileā also tells us that joy increases when it is shared.
No wonder, then, that happiness is the main driver for social media sharing. Emotions layered with and related to happiness make up the majority of this list of the top drivers of viral content as studied by Fractl.

Hereās what Fractlās study of top emotional drivers looks like overlaid on the emotion wheel:

Jonah Berger, professor of marketing at the University of Pennsylvaniaās Wharton School and author of Contagious: Why Things Catch On, studied nearly 7,000 articles in The New York Times to determine what was special about those on the most-emailed list. He found that an article was more likely to become viral the more positive it was.
Googleās Abigail Posner describes this urge as an āenergy exchange:ā
āWhen we see or create an image that enlivens us, we send it to others to give them a bit of energy and effervescence. Every gift holds the spirit of the gifter. Also, every image reminds us and others that weāre alive, happy and full of energy (even if we may not always feel that way). And when we ālikeā or comment on a picture or video sent to us, weāre sending a gift of sorts back to the sender. Weāre affirming them. But, most profoundly, this āgiftā of sharing contributes to an energy exchange that amplifies our own pleasure ā and is something weāre hardwired to do.ā
Sadness helps us connect and empathize
Perhaps fitting if one looks at sadness as the other side of happiness, the emotions of sadness and sorrow light up many of the same regions of the brain as happiness.

But when the brain feels sadness, it also produces particular neurochemicals. A study by Paul Zak looked at two interesting ones in particular.
Zak has study participants watch a short, sad story about a boy with cancer.
As they experienced the story, the participants produced cortisol, known as the āstress hormoneā; and oxytocin, a hormone that promotes connection and empathy. Later, those who produced the most oxytocin were the most likely to give money to others they couldnāt see.
Zak posits that oxytocinās ability to help us create understanding and empathy may also make us more generous and trusting. In a different study, participants under the influence of oxytocin gave more money to charity than those not exposed to the chemical.
āOur results show why puppies and babies are in toilet paper commercials,ā Zak said. āThis research suggests that advertisers use images that cause our brains to release oxytocin to build trust in a product or brand, and hence increase sales.ā
Fear/surprise make us desperate for something to cling to
Although those who are prone to anxiety, fear and depression also exhibit a higher ratio of activity in the right prefrontal cortex, the emotion of fear is mostly controlled by a small, almond-shaped structure in the brain called the amygdala (seen below).

The amygdala helps us determine the significance of any scary event and decides how we respond (fight or flight). But fear can also cause another response that might be interesting to marketers in particular.
A study published in the Journal of Consumer Research demonstrated that consumers who experienced fear while watching a film felt a greater affiliation with a present brand than those who watched films evoking other emotions, like happiness, sadness or excitement.
The theory is that when weāre scared, we need to share the experience with others ā and if no one else is around, even a non-human brand will do. Fear can stimulate people to report greater brand attachment.
āPeople cope with fear by bonding with other people. When watching a scary movie they look at each other and say āOh my god!ā and their connection is enhanced,ā says study author Lea Dunn. āBut, in the absence of friends, our study shows consumers will create heightened emotional attachment with a brand that happens to be on hand.ā
Anger/disgust make us more stubborn
The hypothalamus is responsible for anger, along with a lot of other base level needs like hunger, thirst, response to pain and sexual satisfaction.

And while anger can lead to other emotions like aggression, it can also create a curious form of stubbornness online, as a recent University of Wisconsin study discovered.
In it, participants were asked to read a blog post containing a balanced discussion of the risks and benefits of nanotechnology. The body of the post was the same for everyone, but one group got civil comments below the article while another got rude comments that involved name-calling and more anger-inducing language.
The rude comments made participants dig in on their stance: Those who thought nanotechnology risks were low became more sure of themselves when exposed to the rude comments, while those who believed otherwise moved further in that direction.
Even more interesting is what happened to those who previously didnāt feel one way or another about nanotechnology. The civil group had no change of opinion.
Those exposed to rude comments, however, ended up with a much more polarized understanding of the risks connected with the technology.
Simply including an ad hominem attack in a reader comment was enough to make study participants think the downside of the reported technology was greater than theyād previously thought.
So negativity has a real and lasting effect ā and itās evident in how content gets shared, too. In the previously mentioned New York Times viral content study, some negative emotions are positively associated with virality ā most specifically, anger.

Why emotions are important in marketing
What does all this teach us as social media sharers and marketers? That emotions are critical ā maybe even more than previously thought ā to marketing.
In an analysis of the IPA dataBANK, which contains 1,400 case studies of successful advertising campaigns, campaigns with purely emotional content performed about twice as well (31% vs. 16%) as those with only rational content (and did a little better than those that mixed emotional and rational content).

That makes sense based on what scientists know about the brain now ā that people feel first, and think second. The emotional brain processes sensory information in one fifth of the time our cognitive brain takes to assimilate the same input.
And since emotions remain tied to base evolutionary processes that have kept humans safe for centuries, like detecting anger or fear, theyāre so primal that weāll always be wired to pay attention to them ā often with surprisingly powerful results.
Like this one: In a twist on the customer survey, Generac, a standby generator manufacturer, asked some of their customers to draw their experience with the generators.
As reported in the Harvard Business review:
They saw men drawing their generators as superheroes protecting their family, and women drawing the fear of being without one like sinking on the Titanic. This exercise led them to change their marketing from technical specs to testimonials of real consumers telling their stories of how Generac saved their lives and homes. It has helped their business double in the last 2 years to $1.2 billion.
Emotion ā the feeling of overcoming a primal fear ā was the driver that moved their customers.
Thatās why Googleās Abigail Posner says we canāt underestimate the importance of understanding the science of emotion in marketing:
āUnderstand the emotional appeal and key drivers behind the discovery, viewing, sharing and creation of online video, photography and visual contentā¦.In the language of the visual web, when we share a video or an image, weāre not just sharing the object, but weāre sharing in the emotional response it creates.ā
