Notice I said "no effect beyond the placebo effect". Subliminal tapes are usually marketed with specific claims, such as "if you listen to this, you will have lucid dreams," and then you may get a placebo effect. On the other hand, if you are listening to a tape and have no reason to believe that there are subliminal messages on it, there is no effect at all.
