— I often hear people say they “can’t be hypnotized” because they tried it once and nothing happened. In my experience – which happens to match what I learned in hypnosis class – an experienced hypnotist can hypnotize anyone, so long as the subject is willing. Where the confusion comes in is that only about 20% of the public can experience what hypnotists sometimes call “the phenomena.” The phenomena describes any situation in which the subject experiences a full-blown illusion, such as seeing something that isn’t there, or feeling something that isn’t real.

In general, mechanics that works for subliminal messages is different than one used to hypnotize somebody. Level of 'agreement' between those two techniques differ and in my experience success rate is better with subliminal messages.

Hypnosis has been well researched to be effective. Subliminal messages have been well studied to be bogus.
