Subliminal persuasion

Accusations have been made by various groups that backmasking can be used to create subliminal messages.

Fundamentalist Christian groups

Various fundamentalist Christian groups have declared that Satan—or Satan-influenced musicians—use backmasked messages to subliminally alter behavior. Pastor Gary Greenwald claimed that subliminal messages backmasked into rock music induce listeners towards sex and drug use. Minister Jacob Aranza wrote in his 1982 book Backward Masking Unmasked that rock groups "are using backmasking to convey satanic and drug related messages to the subconscious." Christian DJ Michael Mills argued in 1981 that "the subconscious mind is being successfully affected by the repetition of beat and lyrics—being affected through a subliminal message." Mills has toured America warning Christian parents about subliminal messages in rock music

 hearings that:

The message [of a piece of heavy metal music] may also be covert or subliminal. Sometimes subaudible tracks are mixed in underneath other, louder tracks. These are heard by the subconscious but not the conscious mind. Sometimes the messages are audible but are backward, called backmasking. There is disagreement among experts regarding the effectiveness of subliminals. We need more research on that.

Stuessy's written testimony stated that:

Some messages are presented to the listener backwards. While listening to a normal forward message (often somewhat nonsensical), one is simultaneously being treated to a backwards message (in other words, the lyric sounds like one set of words going forward, and a different set of words going backwards). Some experts believe that while the conscious mind is absorbing the forward lyric, the subconscious is working overtime to decipher the backwards message.

", and other sound passages made up for the experiment. Vokey and Read concluded that if backmasking does exist, it is ineffective. Participants had trouble noticing backmasked phrases when the samples were played forwards, were unable to judge the types of messages (Christian, Satanic, or commercial), and were not led to behave in a certain way as a result of being exposed to the backmasked phrases. Vokey concluded that "we could find no effect of the meaning of engineered, backward messages on listeners' behaviour, either consciously or unconsciously." Similar results to Vokey and Read's were obtained by D. Averill in 1982. A 1988 experiment by T.E. Moore found "no evidence that listeners were influenced,
consciously or unconsciously, by the content of the backward messages." In 1992, an experiment found that exposure to backward messages did not lead to significant changes in attitude. Psychology professor Mark D. Allen says that "delivering subliminal messages via backward masking is totally and ridiculously impossible".

states that "you probably won't hear [backmasked] messages until somebody first points them out to you. Perception is influenced by expectation and expectation is affected by what others prime you for." In 1984, S. B. Thorne and P. Himelstein found that "when vague and unfamiliar stimuli are presented, [test subjects] are highly likely to accept suggestions, particularly when the suggestions are presented by someone with prestige and authority." Vokey and Read concluded from their 1985 experiment that "the apparent presence of backward messages in popular music is a function more of active construction on the part of the perceiver than of the existence of the messages themselves."
