The ''Lady Macbeth'' effect or ''Macbeth'' effect is a priming effect that occurs when response to a cleaning cue is increased after having been induced by a feeling of shame.〔 The effect is named after the Lady Macbeth character in the Shakespeare play ''Macbeth''; she imagined bloodstains on her hands after committing murder. In one experiment, different groups of participants were asked to recall a good or bad past deed, after which they were asked to fill in the letters of three incomplete words: "W_ _H", "SH_ _ER" and "S_ _P". Those who had been asked to recall a bad deed were about 60% more likely to respond with cleansing-related words like "wash", "shower" and "soap" instead of alternatives such as "wish", "shaker" or "stop". In another experiment, experimenters were able to reduce choice-supportive bias by having subjects engage in forms of self-cleaning. The effect is apparently localized enough that those who had been asked to lie verbally preferred an oral cleaning product and those asked to lie in writing preferred a hand cleaning product over the other kind of cleanser and other control items. However, others have failed to replicate the basic findings of this effect using larger samples.〔Earp, B. D., Everett, J. A. C., Madva, E. N., & Hamlin, J. K. (in press).
