Origins
It was in 1898 when a book containing the basic principles of subliminal messaging was published. The book was ‘New Psychology’ by E.W. Scripture. Then in 1900, the Müller-Lyer illusion came out. Where it was claimed that the illusion was due to the subconscious mind.
Then there was Harry Hollingworth, an American Psychologist that published an advertising book that said subliminal messages can be used by advertisers to sell their products. From then on, further studies on the said messaging system have been done.
More Development
During the World War II, a tachitoscope was developed that used the method of subconscious imaging. It’s an instrument that flashes a picture for a very short time. This was used to train the soldiers to be able to recognize the planes of their enemies. Now days, it is used to train people to read faster and test their sighting skills.
Technology has improved and subliminal messages are in different forms already. Now days, it is not only available to scientists and the government but also for public use. It can be purchased by anyone in the public either for his or her own private use or not. Acquiring subliminal media is very easy now and accessible to everyone.
A lot of people believe in it, and sometimes-even use it to, as they say ‘improve their lives’. They offer messages to help modify certain behaviors such as smoking, lack of confidence, being too lazy and much more. Many see it as the answer to the tantamount of problems they have.
