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.
Dr Schnall’s study was inspired by some previous work of her own. She had found that when feelings of disgust are instilled in them beforehand, people make decisions which are more ethical than would otherwise be expected. She speculates that the reason for this is that feeling morally unclean (ie, disgusted) leads to feelings of moral wrongness and thus triggers increased ethical behaviour by instilling a desire to right the wrong. However, as the cleanliness and purification rituals found in many religions suggest, physical cleanliness, too, is linked to moral behaviour, so she decided to investigate this as well.
