Enjoyment: how to spot a genuine smile.
Enjoyment is the primary positive emotion, signaling pleasure and safety. But not all smiles are real. True enjoyment involves specific, involuntary muscles around the eyes that are incredibly difficult to fake. Train your eye to catch the truth.
What is Enjoyment?
Enjoyment is the only purely positive emotion among the seven universal facial expressions. It acts as the social glue of human interaction, signaling that we are friendly, non-threatening, and experiencing pleasure or relief.
However, because smiling is the most common social mask, the face of enjoyment is also the most frequently faked. Humans use polite smiles to cover up discomfort, assert compliance, or feign agreement. Recognizing true enjoyment requires looking past the mouth and focusing entirely on the subtle mechanics of the eyes.
How to recognize genuine enjoyment
The key to decoding enjoyment is ignoring the mouth. A fake smile can easily manipulate the lips, but a genuine smile of enjoyment—known scientifically as a Duchenne smile—requires the involuntary contraction of the muscles orbiting the eyes.

Facial markers to watch
To verify if a smile is authentic, you must look for the synergy between two specific facial muscles. If one is missing, the emotion is likely manufactured.
Common FACS markers: AU12 (lip corner puller) combined with AU6 (cheek raiser - the 'Duchenne' marker).
Pleasure, affiliation, relational safety, reward.
"“This is good.” / “I am open and safe.”"
As a social function, expressing enjoyment plays a critical role in signaling friendliness and assuring that we are not a threat to others. From a biological standpoint, enjoyable emotions motivate us to pursue actions that are beneficial for our survival and well-being.
Enjoyment micro-expressions: the stealth signals
Genuine enjoyment frequently leaks as a micro-expression when someone is actively trying to conceal their delight. For instance, in a high-stakes negotiation, if a buyer hears a price that is much lower than expected, they will try to maintain a poker face to avoid showing their hand.
During that fraction of a second, the lips might remain pressed or neutral, but the orbicularis oculi muscle around the eyes will involuntarily twitch. Catching that subtle eye crinkle gives you absolute confirmation that they are pleased with the outcome, allowing you to hold your ground.

Intensity levels
Enjoyment scales from a quiet feeling of contentment to explosive, uncontrollable laughter. Training your eye across these intensities helps you differentiate between a polite nod of agreement and a deep, genuine sense of satisfaction.
Enjoyment covers a vast array of positive states, escalating through: Sensory Pleasure, Amusement, Relief, Excitement, Wonder, and finally Ecstasy.
MicroSigns trains you to spot the AU6 'Duchenne' marker even at the 'subtle' intensity level, where the wrinkles are barely visible.




Common confusions
Because smiling is our default social mask, enjoyment is the emotion we are most often tricked by. MicroSigns trains you to see through the noise.
Why it's confused
People use polite, social smiles constantly to appear agreeable, mask discomfort, or lie. Both actions pull the lip corners up.
How to tell the difference
A fake smile only activates the mouth (AU12). Genuine enjoyment almost always includes the involuntary contraction of the muscle around the eyes (AU6), raising the cheeks.
Why it's confused
Both emotions involve the lip corners moving upwards, which can make a dismissive smirk look like a friendly smile.
How to tell the difference
Enjoyment is symmetrical and engages the cheeks and eyes. Contempt is strictly asymmetrical, isolating tension to one side of the mouth with no eye involvement.
Why it's confused
Relief is a positive state that often follows a negative emotion like fear or anxiety, frequently resulting in a smile.
How to tell the difference
While relief includes a smile, it usually features a distinct relaxation of physical tension, a deep exhale, and a slight downward tilt of the head, rather than pure joyous elevation.

Most people naturally focus on the mouth when trying to read a face. To master the detection of genuine enjoyment, you must unlearn this habit and train your brain to snap its focus to the eyes.
The MicroSigns arena forces this behavioral shift. By blasting you with high-speed mix of fake and genuine smiles, you will quickly develop a reliable reflex to verify the authenticity of any positive expression.
The Flash
You are exposed to an expression for a fraction of a second, preventing your brain from second-guessing.
Forced Choice
You must instantly decide if the smile was genuine (Enjoyment) or a polite social mask.
Baseline Comparison
Review the expression against the neutral face to explicitly see if the cheek volume increased.

Frequently Asked Questions about Enjoyment
What exactly is a Duchenne smile?
Named after the French neurologist Guillaume Duchenne, it is the scientific term for a genuine smile of enjoyment. It requires the involuntary contraction of the orbicularis oculi muscle (creating eye wrinkles) alongside the lip pull.
Can people fake the eye wrinkles?
It is extremely difficult. While about 10% of people can voluntarily contract the outer part of the eye muscle, the timing, symmetry, and duration are rarely convincing compared to a spontaneous genuine smile.
Why do people smile when they are uncomfortable?
Smiling is an appeasement gesture. In social situations, we often flash a 'fake' or nervous smile to signal submission, diffuse tension, or hide the fact that we are actually experiencing fear or sadness.
Is enjoyment always a high-energy emotion?
No. Enjoyment covers the entire spectrum of positive feelings. It can be the high-energy excitement of winning a game, or the low-energy, subtle contentment of relaxing after a hard day.
How can I practice spotting genuine enjoyment?
The best way is to focus purely on the outer corners of the eyes. When someone smiles at you, actively check if their cheeks puff up and their eyes crinkle. If the eyes are dead, the smile is a mask.
