As Seen On

Subliminal messages have been a topic of debate and fascination for decades. On the one hand, proponents argue that these hidden messages have the power to influence our thoughts and actions in ways we don’t even realize. 

On the other hand, detractors argue that subliminal messages are unethical, manipulative, and potentially harmful. So what are subliminal messages, and do they really work?

This blog post will explore the history, science, and ethics of subliminal messaging to help you decide for yourself. Get ready to dive into the world of hidden messages and discover the truth behind this controversial topic.

What are Subliminal Messages?

Subliminal messages are messages that are designed to influence the subconscious mind without the conscious mind being aware of it. These messages are often below the level of conscious perception, but the brain still processes them. 

They can be delivered in various forms, such as images, sounds, or even words and phrases that are presented too quickly to be consciously perceived. Subliminal messaging aims to shape thoughts, emotions, and behaviours without the recipient’s awareness. 

The effectiveness of subliminal messages is a topic of much debate, with some researchers claiming that they can impact behaviour. In contrast, others argue that their effects are overstated.

History of Subliminal Messages:

The history of subliminal messages dates back to the 1950s when a market researcher named James Vicary claimed that he could increase popcorn and Coca-Cola sales in a movie theatre by flashing subliminal messages on the screen. He claimed that he used messages like “Drink Coca-Cola” and “Eat popcorn” to influence the behaviour of moviegoers. Although this study was later discredited and found to be a hoax, it sparked widespread interest in the potential power of subliminal messaging.

In the decades that followed, subliminal messages became a topic of interest for advertisers, politicians, and even the military. Many reports of subliminal messages were being used in advertising, political campaigns, and military propaganda. However, despite the widespread interest, there was very little scientific evidence to support the claims about the effectiveness of subliminal messaging.

In the 1970s and 1980s, the Federal Communications Commission (FCC) in the United States ruled that the subliminal message in advertising was misleading and banned its use. This ruling helped to reduce the use of subliminal messages in commercial advertising. Still, it did not stop the use of subliminal messages in other forms, such as self-help tapes and other audio products.

Today, subliminal messaging remains controversial, with some researchers and marketers continuing to explore its potential while others warn against its unethical and manipulative nature. Despite the ongoing debate, one thing is clear: the history of how subliminal messaging works, is a fascinating and ongoing story that continues to challenge our beliefs about the power of the subconscious mind.

How do Subliminal Messages work?

Subliminal messages are believed to work by bypassing the conscious mind and influencing the subconscious mind directly. The idea is that presenting information below the level of conscious perception can be processed by the brain without being noticed or critically evaluated. It allows the message to influence thoughts, emotions, and behaviours without the recipient being aware of it.

The exact mechanism by which subliminal messages influence the brain still needs to be better understood, but several theories exist. 

One theory is that subliminal messages can activate automatic responses in the brain, such as instincts and emotions, which can then influence behaviour. 

Another theory is that these subliminal images and messages can plant ideas and beliefs in the subconscious mind that can then shape attitudes and behaviours.

The evidence for the effectiveness of subliminal messages is mixed, with some studies showing a significant impact on behaviour while others show little to no effect. 

The quality and design of the studies are major factors in determining the validity of the results. Some studies have been criticized for poor design, small sample sizes, and lack of control groups.

Controversy and Ethics around Subliminal Messages:

The use of subliminal messages has been controversial since it was first introduced. Some people believe that subliminal messages are unethical and manipulative, as they aim to influence people’s thoughts and behaviours without their knowledge or consent. Others argue that subliminal messages are harmless and can be used for positive purposes, such as self-help and personal development.

One of the main criticisms of subliminal messaging is that it is deceptive and violates people’s right to make informed decisions. It can lead to concerns about privacy, autonomy, and control over one’s thoughts and actions. By hiding messages below the level of conscious perception, subliminal messages can influence people’s thoughts and behaviours without their knowledge, which some argue is unethical.

Another criticism of subliminal messages is that they can be used for malicious purposes, such as political propaganda, military psychological operations, or commercial advertising. There is a fear that subliminal messages can be used to manipulate people’s thoughts and behaviours to benefit those in power.

In addition to ethical concerns, there is also a question about the effectiveness of subliminal messages. Despite decades of research, the evidence for the impact of subliminal messages on behaviour is mixed, with some studies showing a significant impact while others show little to no effect. It raises questions about the validity of the claims made about the power of subliminal messaging and whether it is a legitimate tool for influencing human behaviour.

Subliminal messages remain a controversial and widely debated topic. While some research on subliminal influence suggests that they can effectively influence behaviour, the results and the ethical implications of using subliminal messages to manipulate people’s thoughts and actions are mixed.

How Are Subliminal Messages Used in Advertising?

Subliminal messages in advertising often take advantage of our subconscious mind, aiming to influence our attitudes, perceptions, or behaviours towards a product or brand without being consciously aware. Here are a few ways subliminal ads and messages have been used:

  • Hidden Images and Words: Advertisers might embed hidden images or words within an advertisement. These elements are often related to positive emotions, desires, or needs, which the advertiser wants the viewer to associate with their product. For example, an ice cream ad might include a faint image of a sunny beach, aiming to make viewers associate their product with feelings of relaxation and happiness.
  • Subtle Symbols: Symbols can have powerful subconscious effects. For instance, a logo or image might be designed to look like something else at a subconscious level. Consider the FedEx logo, where a hidden arrow between the “E” and “x” can symbolize speed and precision.
  • Subaudible Messages: In this case, audio messages are incorporated into music or other sounds at a volume level typically unnoticed by the conscious mind. While this technique is not widely used due to regulatory restrictions, there have been historical instances where it was believed to be applied.
  • Flash Frames: This technique involves flashing an image or text for a split second, usually too quick for the conscious mind to register but potentially impactful on the subconscious. However, the use of flash frames is generally prohibited in many countries due to ethical concerns.
  • Priming: This technique uses images, sounds, or words to ‘prime’ the viewer by creating a specific mindset or mood. For example, a fast food ad might show a person eating and looking very satisfied, priming viewers to feel hungry or crave that food.

It’s important to note that while these techniques can be intriguing to discuss, the effectiveness of subliminal advertising is highly debated within the scientific community.

Frequently Asked Questions:

How are subliminal messages used in advertising?

Subliminal messages can be used in advertising in various ways, including hidden images and words, subtle symbols, subaudible messages, flash frames, and priming. These methods aim to influence the viewer’s attitudes, perceptions, or behaviors towards a product or brand without them consciously realizing it.


The intrigue and controversy surrounding subliminal messages persist, with a clear dichotomy between those who advocate for its potential benefits and those who voice ethical concerns. From its early introduction in the 1950s, when James Vicary claimed to manipulate consumer behaviour through subliminal messages, to present times, the efficacy and ethics of subliminal messages have been hotly contested.

During some research points towards the potential for subliminal messages to affect behaviour, other studies present contradicting results. The complex interplay between the conscious and subconscious mind, and the effects of subliminal stimuli that seemingly bypass our awareness, continue to baffle scientists and spark intense debates.

Ethically, subliminal messages raise serious questions about autonomy, privacy, and informed consent. The prospect of hidden messages influencing our thoughts, emotions, and behaviours without our knowledge or approval is a cause for concern and warrants a cautious approach.

In conclusion, subliminal messaging remains a fascinating and controversial field. Its true potential and limitations are yet to be fully understood. Still, it is clear that it provokes important questions about the nature of our minds, our autonomy, and the ethics of influence. 

The study of the subliminal perception of messages continues to challenge our understanding of human cognition and consciousness, and it remains an exciting and contentious area of research in psychology and beyond.

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!
