“This research reveals that air pollution may have potential ethical costs that go beyond its well-known toll on health and the environment,” says behavioral scientist Jackson G. Lu of Columbia Business School, the first author of the research. “This is important because air pollution is a serious global issue that affects billions of people—even in the United States, about 142 million people still reside in counties with dangerously polluted air.”
Previous studies have indicated that exposure to air pollution elevates individuals’ feelings of anxiety. Anxiety is known to correlate with a range of unethical behaviors. Lu and colleagues hypothesized that pollution may ultimately increase criminal activity and unethical behavior by increasing anxiety.
In one study, the researchers examined air pollution and crime data for 9,360 US cities collected over a 9-year period. The air pollution data, maintained by the Environmental Protection Agency, included information about six major pollutants, including particulate matter, carbon monoxide, nitrogen dioxide, and sulfur dioxide. The crime data, maintained by the US Federal Bureau of Investigation, included information about offenses in seven major categories, including murder, aggravated assault, and robbery.

They saw this collage as they wrote a diary entry describing what it would be like to live in the location depicted. (Credit: ©Jackson G. Lu, Julia J. Lee, Francesca Gino, and Adam D. Galinsky)
