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".[1]
