Washing your hands may make you evil

Cleanliness may not be next to Godliness after all. Researchers have found that experimental subjects who had been primed with concepts related to cleanliness (e.g. pure, immaculate, pristine, et cetera) or who had just washed their hands were less likely to be troubled by questionable behavior, which they rated on a scale of 0 (perfectly okay) to 9 (very wrong).  The Economist has the story.

The researchers report that those who were given the “clean” words or who washed themselves rated the acts they were asked to consider as ethically more acceptable than the control groups did. Among the volunteers who unscrambled the sentences, those exposed to ideas of cleanliness rated eating the family dog at 5.7, on average, on the wrongness scale whereas the control group rated it as 6.6. Their score for using a kitten in sexual play was 6.7; the control group individuals gave it 8.3. Similar results arose from the handwashing experiment.

Dr. Simone Schnall conducted the research, which is published in Psychological Science.  The Economist reports that her hypothesis is that “feeling morally unclean (i.e. disgusted) leads to feelings of moral wrongness and thus triggers increased ethical behaviour by instilling a desire to right the wrong.”  The article concludes by saying:

Physical purification, in other words, produces a more relaxed attitude to morality. Perhaps it is no coincidence that Pontius Pilate is portrayed in the Bible as washing his hands of the decision to crucify Jesus. Something to think about for those who feel that purification rituals bring them closer to God.

Anyway, if you want to manipulate someone into doing something wrong, get them to wash up before making your proposal.
