How subliminal or binary beats work and they are effective or not and any side effects of listening to those subliminal or they are just fake.

Question

A search through the US National Library of Medicine/PubMed/Medline will reveal many studies with systematic assessment, where subliminal audio has been shown to outperform the placebo.
Search for yourself. These studies include both behavioural tests and fMRI studies. You?ll find proof that subliminal messaging has influences anxiety, agoraphobia, maths and learning potential. These are the larger studies - but the list goes on.
The confusion comes in, when subliminal audio is aimed at achieving things which it cannot change. Its not good for anything and everything.
There are few which are even more interesting, for example effects found where the subjects were not aware of the studies. Placebo is a big part of subliminal self-help audio, but then so are painkillers and anti-depressants etc.
