Voluntarily wiggling your ears is genuinely uncommon. Researchers describe the skill as rare in humans, though precise prevalence figures are hard to pin down because the ability exists on a spectrum, from slight twitches invisible to onlookers all the way to dramatic side-to-side flaps.1PubMed. Neuroplasticity in normal and brain injured patients: potential relevance of ear wiggling locus of control and cortical projections Informal surveys over the decades have placed the share of people who can visibly move their ears somewhere around 10 to 20 percent, but those numbers come mostly from self-report, and the line between “can move” and “can’t” is blurrier than it sounds. What makes the topic genuinely interesting is that the muscles responsible are still there in everyone, they still fire in response to sounds and eye movements, and some researchers are now finding practical uses for them.
The Muscles Everyone Has but Few Can Control
Your outer ear is surrounded by three extrinsic auricular muscles: the anterior auricular muscle at the front, the superior auricular muscle on top, and the posterior auricular muscle behind the ear. On top of those, there are six smaller intrinsic muscles embedded within the ear itself.2PubMed Central. Neuroprosthetics for Auricular Muscles: Neural Networks and Clinical Aspects In animals that swivel their ears to track sounds, these muscles are large, well-innervated, and under fine voluntary control. In humans, the extrinsic set has shrunk considerably, yet they remain functional tissue, not just decorative leftovers. When researchers have placed wire electrodes directly into these muscles, they found that all three tend to fire together during deliberate ear movement, pulling the ear upward and backward as a coordinated unit.3PubMed. EMG study of the anterior, superior and posterior auricular muscles in man
That same electromyography work revealed something else: the auricular muscles are not silent during everyday life, even in people who would say they cannot wiggle their ears at all. The strongest electrical activity showed up during natural smiling and yawning. Opening the mouth alone or shifting the scalp also produced measurable contractions, though less reliably, only in about half of the subjects tested.3PubMed. EMG study of the anterior, superior and posterior auricular muscles in man So the wiring is live in most people. The gap between ear wigglers and non-wigglers is less about anatomy and more about whether someone has stumbled into conscious control of that circuit.
Why Humans Lost Most of Their Ear Mobility
In the broader sweep of primate evolution, ear swiveling is the norm rather than the exception. Prosimians, the group that includes lemurs and tarsiers, move their ears freely to locate sounds in the dark. That ability appears to have faded as primates shifted toward daytime activity, first in New World monkeys and then more dramatically in Old World monkeys and apes. Along the way, primate ears became shorter, more rigid, and progressively harder to move. Certain muscles vanished entirely: lesser apes such as gibbons still have an inferior auricular muscle that counterbalances the upward pull, but chimpanzees and humans do not.4PubMed Central. Vestigial auriculomotor activity indicates the direction of auditory attention in humans
The underlying logic is straightforward. Once primates evolved large, forward-facing eyes and began relying more on vision than hearing for spatial awareness, there was less survival pressure to maintain a complex ear-orienting system. The muscles shrank, the neural pathways that controlled them became less prominent, and the ears themselves stiffened. What remains in us is a vestigial echo of that system, functional enough to twitch but too weak and poorly controlled to genuinely reorient the ear toward a sound the way a cat or a horse does.
How Cats and Other Animals Compare
Watching a cat rotate one ear toward a noise while the other stays put gives you a sense of how different the ancestral system was. Researchers tracking cat pinna movements found that prominent ear rotations accompany both auditory and visual orienting responses. When a cat hears a sound, its ears respond with two distinct phases: an extremely fast initial movement, starting within about 25 milliseconds of the stimulus, and a slower follow-up that accompanies the animal’s head and eye movement toward the target. The fast component is strongly asymmetric, with the ear on the same side as the sound source showing much larger motion.5PubMed Central. Pinna movements of the cat during sound localization That kind of speed and precision simply does not exist in the human auricular system anymore. Even the most talented ear wiggler is moving both ears together in a general backward-and-upward sweep, not independently targeting a sound source.
The difference is not just muscular. Animals that rely on ear-pointing for survival have muscle spindles, specialized sensory receptors that provide the brain with feedback about muscle position, embedded in their auricular muscles. Research on several non-human primate species, including rhesus monkeys and baboons, found classical spindles in their posterior and superior auricular muscles.6Wiley Online Library / PubMed Central. Muscle spindles in nonhuman primate extrinsic auricular muscles Whether human auricular muscles retain any spindles is less clear, and their absence would help explain why even people who can wiggle their ears have such crude control over the movement. Without proprioceptive feedback, fine-tuning the position of a muscle is extremely difficult.
Your Ear Muscles Still Respond to Sound, Even If You Cannot Feel It
Perhaps the most striking recent finding in this area is that the vestigial auricular muscles are not truly dormant. A 2020 study measured electrical activity in all three extrinsic auricular muscles while participants listened to sounds coming from different directions. Even in people with no conscious ability to move their ears, the muscles responded. When a sound came from behind and to one side, the posterior, anterior, and transverse auricular muscles on that side fired measurably harder than for sounds from the opposite side or from the front.4PubMed Central. Vestigial auriculomotor activity indicates the direction of auditory attention in humans In other words, the brain is still sending the “point toward that sound” command. The muscles just lack the size and mechanical leverage to follow through.
The responses tracked attention, not just stimulus location. When participants were actively listening for something, the muscle activity was more pronounced than when they passively heard the same sounds. This suggests the auriculomotor system is woven into the broader neural network for spatial attention, doing its best to orient the ears toward whatever the brain deems important. The fact that this happens involuntarily, below conscious awareness, is a reminder that vestigial does not mean inert. The system is degraded, not dead.
The Unexpected Link Between Eye Movements and Ear Movements
The connection between ears and spatial attention goes deeper than muscle twitches. Separate research has shown that every time you flick your eyes to look at something, your eardrums physically move, even when there is no sound playing. Using sensitive microphones placed inside the ear canal, researchers detected oscillatory eardrum movements in humans that began as early as 10 milliseconds before the eyes started to shift. These movements depended on the direction and size of the eye movement: larger rightward glances, for instance, produced different eardrum vibrations than leftward ones.7PubMed Central. The eardrums move when the eyes move: A multisensory effect on the mechanics of hearing
The same team found that these eardrum oscillations, measured as pressure changes inside the ear canal, reached a peak-to-peak level equivalent to roughly 57 decibels of sound pressure for moderate eye movements, and they persisted well into the period of steady fixation after the eyes stopped moving.7PubMed Central. The eardrums move when the eyes move: A multisensory effect on the mechanics of hearing That is not trivially small. The working theory is that the brain uses these movements to adjust the auditory system in real time as you shift your gaze, keeping your sense of where sounds are coming from aligned with where you are looking. It is a different kind of ear movement from wiggling, of course, but it underscores a broader point: our auditory hardware is more active and interconnected with other senses than most people realize.
Can You Learn to Wiggle Your Ears?
Many people who can move their ears report discovering the ability accidentally, usually in childhood, by experimenting with facial expressions. That tracks with the electromyography data showing that smiling, yawning, and scalp movements all activate the auricular muscles. If you smile broadly and pay attention to the sensation around your ears, you may notice a slight pull. The trick, according to anecdotal accounts and some clinical observations, is to isolate that sensation from the facial expression that triggered it, gradually learning to fire the auricular muscles without needing to grin.
Whether everyone can eventually learn the skill is an open question. The neuroplasticity hypothesis suggests that the neural pathways responsible for voluntary ear movement exist in a dormant state in most people. One researcher has proposed that if these pathways could be activated, whether through deliberate practice, electrical stimulation, or magnetic stimulation, they might even prove useful in rehabilitation after brain injury, because reawakening a complex motor skill could encourage broader neural repair.1PubMed. Neuroplasticity in normal and brain injured patients: potential relevance of ear wiggling locus of control and cortical projections That idea remains speculative, but it highlights a real observation: the pathway from cortex to auricular muscle is not destroyed in non-wigglers, it is just unused.
Some people who learn the skill as adults describe a period of weeks or months during which they could only move both ears together, followed by a gradual ability to isolate one side. Others never manage to separate the two. That is consistent with the anatomy: because the three extrinsic muscles tend to fire as a coordinated group rather than independently, independent left-right control would require a finer degree of neural differentiation that may or may not develop with practice.
Ear Wiggling as an Interface for Assistive Technology
One of the more creative applications of auricular muscle control has emerged in the field of assistive technology. Because ear movements are discreet, hands-free, and do not interfere with speech or vision, researchers have explored using them as a control signal for devices. A recent study tested an “EarSwitch” concept in which participants used voluntary auricular muscle contractions to operate a basic interface. Participants who could produce the muscle signal achieved high accuracy in controlling the system, with self-reporting accuracy for the relevant muscle contraction reaching about 80 percent.8PubMed Central. Exploring the ‘EarSwitch’ concept: a novel ear based control method for assistive technology
The appeal is obvious for people with severe motor impairments. If you cannot use your hands, eyes, or voice reliably, an ear-based control signal opens up another channel entirely. The challenge is that not everyone can produce a voluntary ear contraction on demand, and even among those who can, the signal can be noisy and hard to distinguish from involuntary activity caused by jaw movements or facial expressions. Still, early results are promising enough that research groups are continuing to refine the concept, looking at better electrode placement, signal processing, and training protocols to expand the pool of potential users.
Why Exact Prevalence Numbers Are So Slippery
If you have ever tried to look up what percentage of people can wiggle their ears, you have probably seen figures all over the map. The reason is partly methodological: most estimates come from classroom demonstrations or informal surveys where someone asks “can you move your ears?” and tallies the hands. That approach has obvious problems. Some people have never tried and assume they cannot. Others think they are moving their ears when they are really just raising their eyebrows or shifting their scalp. And the threshold matters: should a barely perceptible twitch count, or does it need to be visible across a room?
There is also a biological continuum at play. Given that everyone’s auricular muscles fire during smiling and sound localization, the difference between a “wiggler” and a “non-wiggler” is not a clean binary. It is more like a dial, with some people having slightly better cortical access to those muscles than others. Genetics likely plays a role, since the size and innervation density of the auricular muscles vary from person to person, but no one has identified specific genes responsible. Family clusters exist, with ear wiggling sometimes running in families, but whether that reflects shared genetics, shared environment, or just shared amusement at the party trick is unclear.
What the research does establish is that ear movement is rare as a voluntary, visible skill, somewhere in the minority of the population but not vanishingly so. If you can do it, you are in a relatively small club. If you cannot, there is a decent chance you could learn with enough patient practice, because the underlying hardware is not missing. It is just waiting for a signal strong enough to wake it up.
Other Vestigial Muscles and How Ear Movers Fit the Pattern
The auricular muscles are part of a broader family of vestigial structures that linger in the human body long after their original function has faded. The plantaris muscle in the calf, for instance, is absent in a significant fraction of people and serves no clear mechanical role even when present. Wisdom teeth, the appendix, and the arrector pili muscles that produce goosebumps are other classic examples. What makes the ear muscles slightly unusual in this category is that they remain innervated and active rather than being purely structural remnants. They fire involuntarily in response to sounds, they activate during facial expressions, and in some people they can be voluntarily controlled. That puts them in a gray zone between truly vestigial and merely diminished.
Researchers studying vestigial structures have noted that the timeline for losing a trait can be extremely long. Hundreds of thousands of years may pass with the muscles slowly shrinking and the neural pathways slowly losing priority, but the whole apparatus does not disappear overnight. The auricular system in humans may still be mid-decline, evolutionarily speaking. Whether it will vanish completely depends on whether there is any residual selection pressure to keep it, and given that assistive-technology researchers are finding new uses for it, the answer to that question may be stranger than anyone expected.
