Self-Improvement Through Audio: What Subliminals Are and How They Work
Subliminals and their effect on the subconscious.
A new self-improvement tool has appeared on social media. Creators of special audio recordings — subliminals — promise remarkable results with no extra effort: just listen to music or nature sounds containing hidden messages, and your subconscious will absorb everything you need on its own.
The DeTalks team looked into what subliminals actually are, and whether they can really influence our emotions, physical state, and habits.
What Subliminals Are
Subliminals are audio affirmations designed to influence people's conscious and subconscious minds. These messages are typically hidden behind various sounds (music, nature, ambient noise) and are used to reprogram thoughts, relieve stress, improve well-being, and even help achieve goals.
The concept of subliminals has existed for decades, gaining popularity as far back as the 1950s thanks to the idea that they could be used in advertising to influence consumers. This belief emerged after an experiment that claimed that quickly flashing the phrases 'Drink Coca-Cola' and 'Eat popcorn' during a film screening increased sales. It later turned out this data was fabricated, which led to widespread misunderstanding about what subliminal messages actually are.
Subliminals began catching social media users' attention again, this time in a positive light. They're now known as a tool for achieving goals: better sleep, higher self-esteem, improved appearance, and more — all without extra effort.
How Audio Affirmations Work
The effectiveness of audio affirmations rests on the idea that the subconscious mind absorbs far more information than the conscious mind, and can influence how a person thinks. Researchers believe subliminals bypass the mind's conscious defenses, directly affecting the subconscious and changing behavior, thoughts, and habits.
This hypothesis is also supported by an experiment conducted at Massachusetts General Hospital and Harvard Medical School. At the start, participants were shown photos of faces on a screen while receiving pain stimuli of varying intensity. In the study's second stage, all participants received the same level of pain, but their perception of it now depended on which face had appeared before them. Even when the images flashed too quickly for conscious perception, people still felt more intense pain or relief, based on associations formed earlier.
So even subconscious visual cues triggered both a placebo effect (improvement due to belief in something's effectiveness) and a nocebo effect (worsening due to negative expectations).
This same mechanism applies to the audio that subliminal affirmations are built on. Subliminals are usually concealed within audio tracks so they can't be consciously perceived — as low- or high-frequency statements embedded in background music. A weight-loss subliminal, for instance, might contain positive affirmations about healthy eating and physical activity, disguised as a calm melody. And although the conscious mind doesn't recognize these statements, the subconscious absorbs them and programs the corresponding habits — similar to hypnosis.
Are Subliminals Actually Effective?
A study published in the Journal of Counseling Psychology examined the effectiveness of subliminals in helping people quit smoking. Researchers ran an experiment involving 60 people trying to quit. Participants were split into two groups: one listened to audio affirmations aimed at overcoming nicotine addiction, while the other listened to identical recordings, minus the hidden content. Researchers closely tracked participants' smoking habits over six weeks.
The results showed that the group listening to subliminal messages quit smoking at a significantly higher rate than the other. About 50% of the first group's participants successfully quit, compared to only 20% in the second group.
Other studies also support subliminals' effectiveness. One of them showed that subliminal messages can reduce anxiety levels. Audio affirmations have also been shown to improve cognitive functions, including attention and memory.
The Downside of Audio Affirmations
One drawback of subliminals is the risk of picking up imposed beliefs or desires. In 2019, a scandal broke out around creator Mind Power, whose subliminals contained harmful and negative programming. According to victims of the channel, the videos triggered demonic and sexual dreams, while others claimed Mind Power's audio affirmations sent them to the emergency room.
A person is forced to fully trust the creator of the affirmations, since it's practically impossible to independently verify an audio's hidden message. So there's no guarantee that a subliminal contains positive programming rather than negative.
Subliminals remain a controversial phenomenon: some consider them a useful self-improvement tool, others see them as nothing more than a placebo effect. Research shows they can positively affect emotional and physical well-being, but there's a risk of imposed negative programming, since hidden messages are difficult to verify.
