To Be A Better Negotiator, Show More Facial Expressions

Listen to Dr. Matsumoto on Negotiate Anything Podcast

You may think that in a tough negotiation you need a good poker face, but recent research suggests that being pleasant and facially expressive could actually yield you better results.

Researchers out of Nottingham University in the UK collected data from over 1500 conversations while paying close attention to movements in the face like smiles, eyebrow raises, and nose wrinkles.

Their paper was published in Nature and is entitled “Being facially expressive is socially advantageous”.

They found that people who displayed more facial expressions were seen as more likable and socially successful.

Lead researcher Dr. Bridget Waller said this could explain why humans have more complex facial expressions than any other species.

Negotiation Study Methodology

In Study 1, the researchers recorded semi-structured video calls with 52 participants interacting with a confederate across various everyday contexts.

The researchers showed recorded clips of conversations to more than 170 people and asked them to rate how “readable” (in terms of emotions and expressions) and likable the subjects were in the videos.

In Study 2, they examined video calls of 1315 participants engaging in unscripted Zoom chats.

Facial expressivity indices were extracted using automated Facial Action Coding Scheme (FACS) analysis and measures of personality and partner impressions were obtained by self-report.

Negotiation Study Results

interview-office-meeting-greeting-hand-shakeIn Study 1, more facially expressive participants were more well-liked, agreeable, and successful at negotiating (if also more agreeable).

Participants who were more facially competent, readable, and perceived as readable were also more well-liked.

In Study 2, they replicated the findings that facial expressivity was associated with agreeableness and liking by their social partner, and additionally found it to be associated with extraversion and neuroticism.

These characteristics are part of the five most significant personality dimensions (the Big Five) identified by psychologists, which enable them to characterize personality differences between individuals in a comprehensive way:

  • Openness: willingness to adopt new ideas, experiences and values
  • Conscientiousness: dependability, punctuality, ambitiousness and discipline
  • Extraversion: sociability, assertiveness, adventurousness, dynamism and friendliness
  • Agreeableness: willingness to trust others, good natured, outgoing, obliging, helpful
  • Neuroticism (Emotional stability): self-confidence, equanimity, positivity, self-control

According to the study’s abstract, “these findings suggest that facial behavior is a stable individual difference that proffers social advantages, pointing towards an affiliative, adaptive function”.

Study Implications

This is the first large-scale study to examine facial expression in real-world interactions and researchers say it suggests that more expressive people are more successful at attracting social partners and in building relationships.

The work is part of a project known as Facediff (Individual differences in facial expressivity: Social function, facial anatomy and evolutionary origin), which is funded by the European Research Council.

Detecting Deception in Negotiation

Detecting Deception in Negotiation

Negotiations Ninja featured Humintell’s own Dr. David Matsumoto on their podcast to discuss detecting deception in negotiation!

During the episode Dr. Matsumoto shares his insights on how to read facial expressions, emotions, and intent. For those in negotiation, it’s sometimes difficult to understand what a person is actually feeling or thinking when they’re engaging face-to-face.

Dr. Matsumoto shares the research on less obvious facial expressions a procurement professional may encounter along the way. He’s sharing research into micro-expressions including what they are, what they reveal about the person, and how they communicate with the brain.

This is a fascinating conversation about everything from discipline in judo, to the way our approximately 23 facial muscles work, to his number one tip for professionals – active observation.

Research: Dogs Wag Their Tails To Make Us Happy

It’s amazing you can form such a strong bond with an animal who communicates with you exclusively non-verbally.

If you’re a dog owner, you know the joy of walking in through the door to be greeted by your pup excitedly wagging their tail.

But did you know that dogs are one of the few animals that use their tails primarily for communication?

Despite this fact, scientists still don’t understand exactly why dogs wag their tails. In a new paper published in the journal Biology Letters, researchers outline a few theories.

Most people equate tail wagging with a happy dog, but reality may be more complicated.

Take a look at more research out of the Canine Cognition Center here


There are many possible hypothesis for why dogs wag their tails and a couple of them are listed below.

1. Domestication Syndrome Hypothesis

This hypothesis relates to the human domestication of dogs, which began as early as 35,000 years ago.

Perhaps tail-wagging was a behavior that humans unintentionally selected for, because it was linked with other preferable traits, like tameness or friendliness toward people.

Tail-wagging may have simply been a byproduct of other specifically targeted characteristics.

2. Domesticated Rhythmic Wagging

This hypothesis suggests that humans consciously or unconsciously selected for tail-wagging during domestication, because they are drawn to rhythmic stimuli.


Tail Wagging 101

The new paper adds to the big-picture understanding of what scientists do and don’t know about tail-wagging.

The authors reviewed more than 100 studies about the behavior and summarized their findings: humans likely altered dogs’ tail wagging without realizing it.

According to the Washington Post, “the findings could flip the long-held belief that dogs are wagging their tails because they’re happy. Instead, Hersh and her colleagues suggest that dog tail-wags made people happy, so humans tended to select for that trait when welcoming dog ancestors into their lives and breeding the animal.”


Messages Conveyed by Tail-Wagging

Dogs also seem to wag their tails in different ways to convey different messages.

  • Wagging more to the right means a dog is curious and wants to approach
  • Wagging to the left is correlated with uncertainty
  • Low tail wagging—where dogs pin their tails down against their back legs—is also linked with insecurity and submission

Interestingly, a study found that dogs began wagging their tails more than wolves when they were as young as three weeks old. And another study found that dogs wag their tails faster and more often than other canines.


Domestication of Dogs

Scientists have found that dozens of dogs’ traits and behaviors changed during domestication, including the appearance of their fur, ears, body size — and even their ability to make “puppy-dog eyes.”

In fact, eyebrows give dogs a wider range of human-like facial expressions we can identify with and they play a vital role in how dogs became “man’s best friend.”

Evolutionary psychologists even believe that centuries of domestication “transformed the facial muscle anatomy of dogs specifically for facial communication with humans”.

Feeling angry? Write down your thoughts then throw them away

There are many ways to manage your emotions and researchers out of Nagoya Univeristy have discovered a simple, but effective, strategy to help with anger management.

Writing down your thoughts on the cause of your anger and then throwing that piece of paper away can be an effective way to neutralize your negative feelings.

The study entitled “After being insulted, writing down your feelings on paper then getting rid of it reduces anger” was published in Scientific Reports on Nature.

This important research builds on similar research on the association between the written word and anger reduction as well as studies showing how interactions with physical objects can control a person’s mood.

For example, after a bad breakup you may feel the desire to burn letters or destroy gifts from your ex.

Anger Study Methodology

For their anger project, lead researcher Nobuyuki Kawai and his graduate student Yuta Kanaya asked 50 participants to write brief opinions about important social problems, such as whether smoking in public should be outlawed.

Evaluators then deliberately scored the papers low on intelligence, interest, friendliness, logic, and rationality.

For good measure, evaluators added insulting comments such as: “I cannot believe an educated person would think like this. I hope this person learns something while at the university.”

After handing out these negative comments, the researchers asked the participants to write their thoughts on the feedback, focusing on what triggered their emotions.

One group was told to either roll up the paper with their thoughts and throw it in a bin or keep it in a file on their desk. A second group was told to shred the paper, or put it in a plastic box.

The students were then asked to rate their anger after the insult and after either disposing of or keeping the paper.

Anger Study Results

As expected, all participants reported a higher level of anger after receiving insulting comments.

However, the anger levels of the individuals who discarded their paper in the trash can or shredded it returned to their initial state after disposing of the paper.

Meanwhile, the participants who held on to a hard copy of the insult experienced only a small decrease in their overall anger.

Researchers concluded that “the meaning (interpretation) of disposal plays a critical role” in reducing anger.

The Japanese Tradition Hakidashira

This process is like a Japanese tradition called hakidashisara, in which people write their negative thoughts on a plate then destroy it.

Along with its practical benefits, this discovery may shed light on the origins of the Japanese cultural tradition known as hakidashisara (hakidashi sara refers to a dish or plate) at the Hiyoshi shrine in Kiyosu, just outside Nagoya.

Hakidashisara is an annual festival where people smash small discs representing things that make them angry.

The study’s findings may explain the feeling of relief that participants report after leaving the festival, the paper concluded.

Kawai imagines using his research to help businesspeople who find themselves in stressful situations.

“This technique could be applied in the moment by writing down the source of anger as if taking a memo and then throwing it away when one feels angry in a business situation,” he explained.
