Pratkanis (1994) reported that both groups in his controlled experiment on subliminal self-help tapes reported improvements in the areas they were told would improve, regardless of what tape they received. This suggests that the reported benefits of subliminal self-help tapes are likely due to a placebo effect, rather than any actual subliminal messaging.
