Giving the cold shoulder? Just wash your hands of it.

SciAm warms my heart with a great interview about metaphor. Cognitive psychiatrist Chen-Bo Zhong of the University of Toronto is an expert in why certain feelings are actually processed as feeling something:

I found that people not only use coldness-related terms to describe social rejection (for example, “cold shoulder”), but also experience rejection as physical coldness: feeling cold becomes an integral part of our experience of being socially isolated. This research is consistent with recent theories on embodied cognition as well as general research on the connection between mind and body.

LEHRER: What are some other examples of how seemingly abstract thoughts, such as feeling excluded, can have physical manifestations?

ZHONG: Another example would be the relation between morality and physical cleanliness. In my early work “Washing Away Your Sins: Threatened Morality and Physical Cleansing” in collaboration with Katie Liljenquist [a professor of organizational behavior at Brigham Young University], we discussed how metaphors such as “dirty hands” or “clean records” may have a psychological basis such that people make sense of morality through physical cleanliness.

When people’s moral self image is threatened, as when they think about their own unethical past behaviors, people literally experience the need to engage in physical cleansing, as if the moral stain is literally physical dirt. We tested this idea in multiple studies and showed that when reminded of their past moral transgressions, people were more likely to think about cleansing-related words such as “wash” and “soap”, expressed stronger preference for cleansing products (for instance, a soap bar), and were also more likely to accept an antiseptic wipe as a free gift (rather than a pencil with equal value).

Further, physical cleansing may actually be effective in mentally getting rid of moral sins. In another study, in which participants who recalled unethical behaviors were either given a chance to cleanse their hands or not, we found that washing hands not only assuaged moral emotions such as guilt and regret but also reduced participants’ willingness to engage in prosocial behaviors such as volunteering.

The kicker’s right there at the end of the excerpt (emphasis mine). That’s why metaphors are important, folks.
